A Root-Cause Analysis Agent for Error Feed, Observe Loads 50 to 70% Faster, and Claude 5 and the Gemini 3 Family

Error Feed gets a root-cause analysis agent that investigates a failing cluster on its own and lays out the likely cause. Observe load times drop by 50 to 70% on high-volume projects, the newest Claude 5 and Gemini 3 models are live across evaluations and the AI gateway, and editing a custom eval's prompt now saves and runs a new version. Plus custom date ranges, a Users CSV export, read-only access for the Viewer role, Bland.ai voice support across Simulate and Observe, and a larger dataset upload limit.

2 new model families in evals and the gateway: Claude 5 and Gemini 3
25 MB dataset upload limit, up from 10 MB
Bland.ai added as a voice provider across Simulate and Observe
Monitor New

Root-cause analysis agent in Error Feed

Error Feed's new root-cause analysis agent investigates a failing cluster on its own. It works through the traces in the cluster, streams its reasoning live in the Fix tab, and lands on the likely root cause, caching the result so reopening the cluster brings it back instantly. Feed pages also load a lot faster.
Evaluate New

Claude 5 and the Gemini 3 family are live

Add your Anthropic or Google API key and the newest Claude 5 and Gemini 3 models appear in the model picker across evaluations and the AI gateway. Gemini 3.6 Flash, 3.5 Flash, and 3.1 Flash Lite are priced, so requests to them return an accurate per-call cost and land in your usage with the right credit math from the first call.
Monitor Improved

Faster Observe and dashboards on high-volume projects

Observe load times drop by 50 to 70% on high-volume projects. Trace lists, the Users and Sessions tabs, and dashboard breakdown charts stay fast even across long date ranges, because queries read only the data inside your selected window, so a wide breakdown returns in seconds. Results are unchanged, just faster to return.
Simulate New

Bland.ai as an inbound and outbound voice provider

Connect a Bland.ai voice agent as a provider and its production calls, inbound and outbound, come into both Simulate and Observe. You can run simulations against your Bland agents and trace their real calls alongside your other voice providers.
Evaluate Improved

Custom eval prompt edits are versioned

Editing a custom eval's prompt on the dataset page now saves it as a new eval version and runs that version, so the prompt you edited is the one that gets used. Each edit is captured as a version you can pick from the version dropdown.
Platform Improved

Read-only access for the Viewer role

The Viewer role now gets a consistent read-only view across tasks, evaluations, dashboards, and the agent playground. Write actions like Create, Save, Test, Duplicate, and Delete render as disabled, matching the permissions the role already has, so viewers see exactly what they can act on.
Monitor Improved

Custom date ranges on dashboards

The dashboard date bar now opens a Custom option where you pick any start and end date, and every widget updates to that range. The widget editor keeps the same range on reopen with its dates intact, instead of falling back to a preset.
Evaluate Improved

Eval usage tab

A new Eval Usage tab shows how often each eval has run, with the eval version recorded on every execution, so you can see usage over any time window and tie it back to the version that produced it.
Evaluate Improved

Eval runs show live status

Eval tasks now report their lifecycle status across the product, so a run's state is clear while it works. Long-running and continuous eval tasks keep going and reconcile on their own instead of needing a manual nudge.
Evaluate Improved

A clearer way to map variables into evals

You can now click any row to map it into a field instead of typing the path, across tracing, simulation, and dataset variable mapping. The dataset variable-mapping picker also handles nested JSON and array fields, with search that reaches deep fields directly and a tree that stays legible in dark mode.
Monitor Improved

Export the Users tab to CSV

The Observe Users tab now exports to CSV. The full list streams to a file straight from the view you are already looking at, so you can pull every user out for analysis without paging through the grid.
Evaluate Improved

Export experiment results to CSV

The aggregate experiment Summary view now exports to CSV, with download progress and clear success or error feedback, so you can pull a full experiment out for analysis in one click.
Platform Fixed

Larger dataset uploads

The dataset upload limit moves from 10 MB to 25 MB, so realistic prompt and eval datasets upload without hitting the cap.
API Improved

The AI gateway works with more clients and models

The gateway now accepts max_completion_tokens for the latest OpenAI reasoning models, so your existing OpenAI client reaches them without extra configuration. Chat completions always return a content field, so clients written to the OpenAI shape keep working even when a model returns no text. Sub-cent request costs show at full precision in the gateway logs.
Platform Improved

Smoother self-hosted setup

Self-hosting is easier to stand up. A guided first-run setup walks an operator through launching a self-hosted stack, with live infrastructure checks, browser-based signup, and invite links for the team. One Docker setup now serves both self-hosted and internal deployments, sign-in has a guided flow for creating an account and resetting a password, and Optimization and Knowledge Base are available in the open-source build.
Monitor Fixed

More users per page

The Observe Users grid now shows 50 rows by default and adds a rows-per-page selector. A filter reads against the full set rather than a short first page, so counts match what you expect.
Monitor Improved

View a session from the annotation queue

You can now open a session directly from the annotation queue, without leaving it. When a queued trace or span belongs to a session, open the full session inline and jump back to the trace when you are done.
Monitor Fixed

Dashboard polish

Deleting a dashboard or widget now asks you to confirm first. A chart whose data falls outside its configured axis range shows a clear warning instead of a blank canvas, and an empty dashboard shows an empty state rather than a blank page. Filter chips display the selected value names instead of a count, and the global time filter adds 30-minute and 6-hour options.
Platform Fixed

Delete your own prompt templates

Prompt templates you created can now be deleted from the Prompt Templates drawer, with a confirm step and a success message, so your template list stays tidy.
Evaluate Fixed

LLM-as-a-judge editor matches the agent layout

The LLM-as-a-judge editor now uses the same layout as the agent editor, with correct model logos, so editing a judge feels the same as editing an agent.

Perplexity ships Sonar and gpt-5.1 to self-hosted Future AGI, plus polish across Evals, Observe, and Platform

Straight from Perplexity. The team sent a PR into the open-source Future AGI repo with first-party support for every current Perplexity model on self-host. Plus a new customer-agent task-completion eval, faster audio eval runs when there's no feedback to retrieve, filter and column fixes across Observe, and a pricing and usage page that renders correctly.

API New

Perplexity contributes Sonar and gpt-5.1 to self-hosted Future AGI

Perplexity contributes Sonar and gpt-5.1 to self-hosted Future AGI

Five Sonar variants are now in the eval model picker and the AI gateway: `sonar` (fast, search-augmented chat), `sonar-pro` (the new default with 200K context), `sonar-reasoning` and `sonar-reasoning-pro` (chain-of-thought over live web results), and `sonar-deep-research` (long-form, multi-source investigations). Perplexity's Agent API adds `gpt-5.1` for agent workflows with built-in web search and tool use. Add your Perplexity API key as `PERPLEXITY_API_KEY` to enable them on self-host.

6 new Perplexity models on self-host
50 improvements across evals, observe, and platform
1 new built-in customer-agent eval
Evaluate Improved

New built-in eval: customer-agent task completion

Score whether your agent actually finished the job. A new built-in eval, `customer_agent_task_completion`, reads the full conversation and returns Pass or Fail with a reason on whether a customer-facing agent completed the task the user asked for. Useful as a top-line outcome metric on voice and chat support conversations, alongside the evals you run on each individual turn.
Evaluate Fixed

Regex PII detection: default to all five PII types

If you leave `detect_types` empty on the Regex PII Detection eval, it now scans for all five built-in types (emails, phone numbers, SSNs, credit cards, IP addresses) instead of returning nothing. You can still narrow the list per eval.
Evaluate Fixed

Eval type persists correctly when creating LLM and Code evals

Creating a new LLM-as-Judge or Code eval now writes the right eval type to the row, instead of defaulting to a placeholder. Reopening the eval picks up the correct type. Templates and saved evals behave the same.
Evaluate Fixed

Eval config auto-populates from the baseline column

When you add an eval inside an experiment and pick a baseline column, the eval settings (model, criteria, output type) now auto-fill from that baseline. Faster setup when you're rerunning an existing eval on a new run.
Evaluate Fixed

Eval workflow: a batch of refinements

Variables in your prompt highlight when you connect them to data in the test panel. Turning data injection on or off is now a clean toggle. Once you pick how the eval scores (pass/fail, numeric, choices), that choice is locked, but the specific labels, score numbers, and thresholds stay editable. When you upload expected answers as ground-truth data, you can watch the processing progress in real time. `Pass Rate` is now called `Task Completion Rate` across all stats and charts.
Evaluate Fixed

Eval picker: stale data prevented, mapping disabled while columns load

The eval picker no longer flashes stale data when you reopen it after switching projects. Variable mapping rows are disabled while the source columns are still loading, so you can't map to a column that hasn't arrived yet.
Evaluate Fixed

Custom eval URLs: open on default version, ?v= survives, task errors expandable

Opening a custom eval URL without a version parameter now lands on the default version. A `?v=` parameter in the URL is preserved across navigation inside the eval. When an eval task fails, the error panel has a Show more toggle that expands the full message.
Evaluate Improved

Audio eval runs are ~3.5x faster when there's no feedback to retrieve

Evals that use feedback-based retrieval now skip the lookup when there are no feedback rows yet. On audio-heavy projects with no feedback corpus, a single eval run is roughly 3.5x faster (about a 70% drop in time).
Evaluate Fixed

Clear error when an eval can't reach a media URL

When an eval fails because it can't fetch an image or audio file from the URL you mapped, the error message now says so and points at the URL, instead of returning a generic backend error. Easier to fix mapping mistakes and broken links.
Evaluate Fixed

Dataset evals with template variables in instructions no longer crash

Dataset evals whose instructions contain `{{variable}}` placeholders no longer crash trying to resolve those placeholders as IDs. The instructions stay untouched and the eval runs cleanly.
Evaluate Fixed

semantic_list_contains handles numeric expected values

The semantic_list_contains comparator no longer crashes when the expected value is a number (for example, an ID or a quantity). Numbers are coerced to strings before comparison.
Evaluate Fixed

Static few-shot examples reach the LLM eval

Few-shot example rows stored on a dataset now expand into the prompt for the LLM eval, instead of being passed as metadata only. Few-shot prompting on dataset-backed evals works as documented.
Evaluate Improved

Voice call mapping reaches deeper into the raw log

When voice eval mapping can't resolve a field in the structured trace data, it now falls back to the raw call log. More voice rows map cleanly without manual intervention.
Evaluate Fixed

PDF filter chip in the eval picker is populated

Evals that accept PDF input are now tagged so the PDF filter chip in the eval picker actually lists them. The chip previously returned no results; it now lists every PDF-capable eval.
Evaluate Fixed

Confirmation dialog before deleting an eval template

Deleting an eval template now asks for confirmation. Prevents accidental clicks on the row action.
Evaluate Fixed

Pass and Fail chips on trace eval drawer

When an eval returns a Pass or Fail result, the trace eval drawer shows a Pass or Fail chip instead of 100% or 0%. Makes the outcome obvious at a glance.
Evaluate Fixed

Multi-choice eval output type flows through the playground and picker

If an eval is configured as multi-choice, that flag is now propagated through the playground run and the eval picker, so the run is scored as multi-choice end to end.
Evaluate Fixed

Error localiser: Show more works and composite evals are hidden

The Show more toggle on the error localiser now expands the full per-highlight reason for the highlighted span. The error localiser panel is hidden for composite evals, where it doesn't apply.
Evaluate Fixed

Fix-with-Falcon hides on label-field eval rows that already pass

On evals where the result is stored in the label field, the Fix-with-Falcon button no longer shows up on rows that already pass. Cleans up the action menu on passing rows.
Evaluate Improved

Eval usage rollups: date range and session-target row exclusion

The `/eval-task/get_usage/` endpoint accepts a date range so you can scope usage to any window. Rows targeting sessions are now excluded from the per-trace usage rollup, so the count matches what you see in the UI.
Evaluate Fixed

Data injection on system evals checks your variable mappings

When you turn on data injection for a system eval, every required variable (like the question and expected answer) now needs to be mapped before you can save. The eval is ready to run as soon as you create it.
Evaluate Fixed

Long eval and label names are readable on hover

Truncated names in the Evals list and truncated labels in the Eval Usage detail panel now show the full text in a hover tooltip. The Evals list grid also fills its container properly instead of clipping.
Monitor Fixed

Trace Name and Span Name filter dropdowns populate suggestions

The Trace Name and Span Name filter pickers on Observe now show the list of names from the current project as suggestions, instead of an empty dropdown.
Monitor Fixed

Span-attached annotations appear in the Annotations filter category

Annotations applied at the span level (not just the trace level) are now included in the metrics endpoint that powers the filter picker. The Annotations category in the filter dropdown is populated for span-only score rows.
Monitor Improved

Text filters are case-insensitive across Observe

Filters on text fields (Trace Name, Span Name, model, provider, span attribute strings) now match regardless of case. Searching for `gpt-4o` finds rows tagged `GPT-4O`.
Monitor Fixed

Trace ID and Span ID filters render as single-select

The Trace ID and Span ID filters now render as a single-select control (a radio, no chips, no +N count) since a span belongs to one trace at a time. Reloading and then editing a saved filter with an ID also returns the right rows instead of zero.
Monitor Fixed

Cleared filters stay cleared after a page refresh

Clearing a filter on Observe now sticks. The filter no longer reappears when you navigate away and come back to the page.
Monitor Fixed

Annotation filters: operator dropdown, chip label, and task filter

Categorical and thumbs-up annotation filters now show the right operator dropdown after the page hydrates. The chip label matches the selected operator. The Tasks filter returns rows on thumbs annotations instead of returning empty.
Monitor Fixed

Add and edit filter chips on Sessions, Users, and User Traces

The plus icon to add a filter chip, and click-to-edit on existing chips, now work on the Sessions, Users, and User Traces tabs. Previously these actions only worked on the Traces and Spans tabs.
Monitor Fixed

Column order persists across auto-refresh on every Observe grid

When you reorder columns by dragging on Traces, Spans, Sessions, or Call Logs, the new order survives the next auto-refresh and stays in sync with the display panel.
Monitor Fixed

Consistent grid theme across Traces, Spans, Sessions, and Users

Header text colour, row hover state, and cell padding are now identical across all four Observe grids (Traces, Spans, Sessions, Users), instead of each grid having a slightly different look.
Monitor Fixed

Call Logs grid: autosize works and Call ID column respects the width you set

On the Call Logs grid (used by voice projects), the autosize columns action now fits column widths to content instead of being a no-op. Widening the Call ID column also shows more of the UUID, instead of clamping at 130 pixels and truncating in the middle of the value.
Monitor Fixed

Hover tooltip on long span-attribute column keys in Live Preview

Long span-attribute paths in the Task Live Preview now show the full key as a tooltip on hover, so you can read the path without resizing the column.
Monitor Fixed

Single loading spinner on the Users page

The Users page no longer shows two stacked loading spinners on initial mount. One spinner appears while data loads, then the rows render.
Monitor Fixed

Save View buttons visible, full tab name preserved

The Save View button is now visible against the dark theme on every Observe tab. Long view names truncate visually with an ellipsis instead of being cut down to a shorter stored string, so the full name stays in state.
Monitor Fixed

Agent Graph and Agent Path: real fullscreen, disabled on voice projects

The fullscreen button on the Agent Graph and Agent Path views now opens a real fullscreen view of the graph, and dead zoom controls on Agent Path are removed. On voice projects, where there's no agent graph to render, both tabs are now disabled with a tooltip explaining why, instead of opening to a black screen.
Monitor Fixed

Tasks list chip hover and popover stay usable

Cell chips on the Tasks list now keep their hover colour while the cursor moves onto the popover, so you can read the popover without it closing the moment you move toward it.
Monitor Fixed

Eval tasks list refreshes while rows are pending or running

The eval tasks list now polls while any row is pending or running, so progress updates appear without a manual refresh. Relative-time cells (`2 minutes ago`) also refresh on each poll instead of going stale.
Monitor Improved

Voice projects: call recording on the Error Feed cluster overview

On voice projects, the Error Feed cluster Overview tab now shows the call recording in place of the agent flow diagram, so you can listen to the call that produced the error.
Monitor Fixed

agent_talk_percentage is filterable on voice traces

`agent_talk_percentage` is now a first-class system metric for voice projects. The filter dropdown matches what you see in the grid (`40%` as a single metric), instead of showing `0.4` as a custom attribute.
Monitor Improved

Faster Users tab and session detail loads

The Users tab now loads instead of timing out on workspaces with high session volume, and session detail no longer returns a 400 on slow queries. Both pages reach the data through a faster path on the backend.
Monitor Fixed

Reliable trace ingestion: custom user IDs and span PK retries

Two ingestion fixes. Traces with custom user IDs from the SDK no longer fail to ingest (the CUSTOM enum value was restored). And bulk span writes tolerate primary-key collisions during retry races, instead of dropping the whole batch.
Monitor Fixed

Voice eval fan-out: longer scheduling window

The scheduling window for voice eval fan-out is now twelve hours, so large voice runs don't lose rows when individual evals queue for a long time before starting.
Platform Improved

Pricing and usage page: correct rounding, units, and free-tier savings

The pricing and usage page now rounds small numbers correctly, shows the right units on per-call costs, and surfaces free-tier savings as a separate line. Sub-1 usage and sub-cent costs render legibly. The legend is visible and the period caption matches the selected window.
Platform Fixed

Faster, more reliable signup with reCAPTCHA

The signup form now waits for reCAPTCHA to be ready before allowing submit, so fast typists no longer hit a `reCAPTCHA not ready` error. The page also preconnects to the reCAPTCHA host, so the script loads sooner.
Platform Fixed

Commit action surfaced on the prompt workbench

The Commit button on the prompt workbench is now on the main toolbar, not buried in the More menu. Saved queries are invalidated right after a commit, so the new version shows up immediately in the version list.
Platform Fixed

Better text contrast across Agent, Persona, Scenarios, Test Detail, Eval Picker, and Error Feed

Secondary text colour has been adjusted across the Agent builder, Persona, Scenarios, Test Detail, Eval Picker, and Error Feed pages so labels and descriptions read clearly against the dark theme.
Platform Fixed

Dataset media fetches no longer hang

Image and audio fetches on dataset rows now have a request timeout, so a slow or unreachable URL fails fast instead of hanging the eval indefinitely.
Platform Fixed

ffmpeg calls time out on malformed audio

ffmpeg subprocess calls inside voice and storage paths now have a timeout, so a malformed audio file can't hang a worker indefinitely.
Platform Fixed

Agentic eval Azure callback handles missing invocation params

The agentic eval Azure callback no longer crashes when `invocation_params` comes back as `None`. Useful when Azure returns a short-form response that omits the params block.

Evals on Traces and Sessions, Configurable Eval Context, and Polish Across Evals, Observe, and Simulate

Every eval type (LLM-as-Judge, Code, and Agent) can now score at every level: spans, traces, and sessions. Eval setup also gets simpler: turn on context injection and skip variable mapping entirely. The eval reads the context on its own. Plus two new conversation evals: Dead Air Detection (a Code eval at zero LLM cost) and Conversation Hallucination. Plus eval inputs up to 200K characters, partial inputs as warnings, custom dotted paths in mapping, span-level fields and API columns, and polish across Observe and Simulate.

Evaluate New

Score traces and sessions with any eval

You can now run any eval (LLM-as-Judge, Code, or Agent) at three levels: on one step the agent took (a span), on a full run (a trace), or on a whole conversation (a session). Composite evals work at all three too. A composite eval is one score that combines several evals. Inside a composite, each eval can have its own settings, like a minimum word count or a regex pattern. In Tasks, you can also type custom paths to map deeper fields, not just pick from the dropdown. And if some mapped variables are missing, the eval runs with a warning instead of failing. It still errors only if all of them are missing. Built-in system evals stay strict.

Evaluate New

Skip variable mapping with context injection

You can now skip variable mapping. Turn on context injection and the eval reads the context on its own. Just pick what you want the eval to see: a dataset row, a span, a trace, a session, or a voice call. This works for every eval type (LLM-as-Judge, Code, and Agent). Inside a Task, the right context is picked for you based on the row type. For large traces or sessions, the eval looks at just the spans it needs, not the whole thing.

Trace + Session added to evals
5 context types in eval setup
2 new built-in conversation evals
~70 improvements across evals, observe, and simulate
Evaluate Improved

Two new conversation evals: Dead Air Detection and Conversation Hallucination

Two new built-in evals for voice and conversation projects. Dead Air Detection flags conversations with too much silence. It's a Code eval, so it runs at zero LLM cost (signal analysis on the audio, no model call). You can tune the share of silent audio, the longest single silent gap, and a silence threshold. Conversation Hallucination scores the whole conversation, not one turn at a time. It catches invented facts and unsupported claims that build up across the full exchange, which a single-turn hallucination eval would miss. Add either eval to any voice or conversation project.
Evaluate Improved

Eval inputs accept up to 200K characters

Long inputs no longer get clipped. LLM-as-Judge and Agent evals now accept up to 200K characters of input (was 15K). Fits long agent transcripts, large retrieved contexts, and multi-document grading.
Evaluate Improved

Consistent scoring across built-in numeric evals

Built-in scoring evals (accuracy, balanced accuracy, Cohen's kappa, F-beta, Matthews correlation, precision, and more) now normalise inputs the same way every time: case is ignored, whitespace is handled consistently, and comparing two empty values returns a perfect-match score. Several system eval rule prompts are also refined.
Evaluate API Improved

Eval mapping reaches span-level fields and API columns

You can now map eval variables to span-level fields like latency, cost, and tokens. Use paths like `spans.0.latency_ms`. The API column also accepts the same dotted-path syntax in URL, body, params, and headers. You can send a JSON column as the request body directly (no wrapping needed). And numeric array positions like `items.0.role` work everywhere, including LLM-as-Judge evals.
Evaluate Improved

Code eval parameters: numbers in, required fields enforced

Numeric parameters on code evals (latency limits, percentage thresholds, scoring weights) accept the text values that form fields produce (`200`, `0.75`) and validate them against the min and max bounds. Required parameters keep the Save button disabled until they're filled. Any parameters you add to your custom `evaluate` function appear in the Variable Mapping panel as soon as you type them.
Evaluate Improved

Deleting an eval task removes all related results

Deleting an eval task now removes its results from eval columns, charts, monitors, and filters in one step. No leftover rows or stale entries.
Evaluate Improved

Eval versioning: V1 on publish, full-field snapshots, draft separation

V1 is created the first time you publish an eval, not when you save a draft. Restoring an earlier version brings back every field on the eval (output type, pass threshold, choice scores, error localisation, and tags). When you run an eval, you can change a few settings just for that one run (for example, whether the eval has internet access, or what context to inject) without saving the change to the eval. And draft evals stay in the editor; they join the eval picker only after you publish them.
Evaluate Improved

Eval picker: configuration persists, source-aware naming, local preview filter

Every option you set in the eval picker (model, criteria, run settings, mapping) is saved and restored when you reopen the eval. Auto-generated names include the source (dataset, experiment, workbench, etc.) and a precise timestamp. The right pane has a local preview filter that shows the level you're scoring at (span, trace, session, or voice call). The Save & Add Evaluation button becomes clickable for code evals as soon as mapping is complete.
Evaluate Improved

Built-in evals work out of the box on open-source installs

Open-source installs ship every built-in eval as LLM-as-Judge, ready to run on first boot (no extra setup). On system evals, you can change the model used to judge, but the instructions stay read-only.
Evaluate Fixed

Cleaner eval cells across the platform

When an eval errors, the cell now shows a red 'Error' chip instead of looking blank. Voice and call-log grids hide Reason columns until an eval has filled them in. And eval result values display consistently across formats (number, category, choice list, or score-with-reason).
Evaluate Fixed

Eval tasks: detail-page edits reflect in the list automatically

Updating, pausing, resuming, or renaming an eval task from the detail page refreshes the task list automatically, so changes show up without a hard refresh.
Evaluate Fixed

Evals UI: faster reruns, accurate version banner, cleaner sliders and animations

Editing an eval inside a test execution triggers a rerun. The `Viewing version X` banner reflects the current version state in real time. The Save Version button activates when you've made a change. Required-field asterisks use a consistent style across every field. Pass-threshold sliders display clean whole-number percentages. The eval picker search shows a spinner while a search runs. The in-progress step in optimisation timelines animates with progress. The Evals login carousel uses up-to-date screenshots.
Monitor Improved

Trace ID and Span ID filters on the Tasks page; consistent operators across Observe

Trace ID and Span ID filters work on the Tasks page the same way they do on the Tracing page. Filter operators on span attributes are consistent across every Observe page. Saved views with ID filters reopen with the right operator selected.
Monitor Improved

More discoverable column resize, persistent custom columns across Observe

Observe tables show a clear column resize handle at rest, brighter on hover, with a wider grab area. Custom columns added on any Observe tab (Traces, Spans, Sessions, Users, Voice Calls) persist across refresh, tab switch, and switching saved views.
Monitor Fixed

Trace list: complete user data, filter chips, tag input, and overlay timing

The User column on the trace list shows the trace's end user. Span-attribute filter chips on the Tasks page display the complete operator and value. The enter-arrow icon on the tag input adds the tag on click. Categorical eval scores display consistently across new and historical runs. The `No traces found` overlay is suppressed while data is loading or filters are changing. The property picker handles duplicate property names across categories cleanly.
Simulate Improved

Voice projects: usage visibility, trace-level evals, surfaced errors

Voice provider traffic shows up in usage summaries and billing reports. Trace-level evals (evals that score a trace rather than one step) show up on the trace detail page. Errored evals on voice traces show a red Error chip, kept out of score averages. Customer call logs from the voice provider appear inside the simulation call detail page. Eval tasks run end-to-end on voice calls.
Simulate Improved

Simulate: safer runs and better failure handling

Starting a simulation against a scenario that hadn't finished generating used to give you zero connected calls and a permanent `Pending`. Run New Simulation now waits until every selected scenario is fully ready before it activates. The Edit Agent form used to leave you guessing whether the agent picked up provider changes; it now auto-syncs with the provider the same way Create Agent does, with a clear syncing indicator and an error notification on failure. And when every call in a run errored out, the eval bar used to disappear entirely; it now shows zero so the run still reports a meaningful result.
API Improved

AI gateway: Bedrock structured output and streaming failover

If you're calling Bedrock through the gateway, you can now use the same structured-output format you use for OpenAI and Gemini. The gateway translates it for Bedrock automatically, so you don't need provider-specific request shaping. And streaming chat with provider failover handles a common silent failure: when the upstream stream returns nothing, the gateway switches to the fallback model before the client sees a broken response.

Self-Host in One Command, Jinja2 Prompts, and Polish Across Evals and Observability

Self-host Future AGI in one command with pre-built images and a Windows installer. Prompts add Jinja2 alongside Mustache. Plus Request Explorer and polish.

Platform New

Self-Host Future AGI in One Command

Self-hosting Future AGI is one script: clone the repo, run `bin/install`, log in. The script pulls pre-built service images from Docker Hub, brings the stack up in about 30 seconds, and works on macOS, Linux, and Windows (through Git Bash, WSL, or a new native PowerShell installer). The first account is created from the command line, with no email server required.

Platform New

Prompts now support Jinja2 templates alongside Mustache

Use `{% if %}` for conditionals, `{% for %}` for loops, and Jinja2 filters to transform values inline. The existing Mustache `{{ variable }}` syntax keeps working, and a Template Format dropdown picks between the two per prompt.

~30s self-host pull-to-up
5 pre-built service images
Mustache + Jinja2 prompt templating
14 improvements across evals, observe, and voice
Monitor Improved

Reliable voice evals, no dependency on provider URLs

Future AGI now stores its own copy of every recording the moment the call arrives. Evals on voice traces run against audio you control, with no dependency on the original provider URL, so traces, replays, and eval reruns stay valid as long as you keep the trace. Storing your own copy is on by default for every voice provider and can be switched off per provider.
Evaluate Improved

Export annotations and eval scores alongside traces to datasets

Pick which annotation scores and eval results to export alongside traces when sending them to a dataset. The selected metrics arrive as dedicated columns in the dataset, so it's immediately ready for experiments with baseline scores, training data, or downstream exports — no re-running the evals.
API Improved

Filter and export AI gateway request logs

A new Request Explorer in the AI gateway logs filters every request by model, status, or metadata and exports the result. Useful for cost audits, error investigations, and compliance pulls.
Evaluate Improved

Reach into nested JSON fields from eval and prompt variables

Eval and run-prompt variables accept dotted paths into nested JSON. A single column like `payload` can feed multiple variables (`payload.user`, `payload.request.id`) without flattening the data upstream first.
Monitor Improved

Filter Observe by trace ID or span ID, plus Select all view columns

Paste a trace ID or span ID into the Observe filter bar to jump straight to that trace or span. The view-columns picker has a new Select all toggle.
Monitor Improved

Faster session list on high-volume traces

The session list now loads in seconds on workspaces ingesting millions of traces. No more waiting at a spinner to pick up a session for review.
Evaluate Improved

API columns: smoother edits, visible progress

Edits to an API column's URL, method, headers, params, or body now sync across devices and browsers. Requests run in batches, so rows fill in as each batch completes and the column's progress is visible while it runs.
