Vapi on Future AGI
Voice & Realtime
Vapi voice agents — capture STT, LLM, and TTS spans end-to-end.
What you get
Everything traced, scored, and improvable
One install instruments Vapi on OpenTelemetry. Future AGI then layers evaluators, optimisers, and simulations on top of the same trace tree — no second SDK, no double instrumentation.
Trace
Auto-instrumented spans
Every Vapi call becomes a span — inputs, outputs, latency, tokens, cost, model name, tool args, retrieval results, and chain steps captured automatically.
Evaluate
70+ evaluators on every span
Attach Groundedness, Context Relevance, Prompt Injection, Toxicity, and 70+ more — purpose-built scorers powered by the Turing eval models, not generic LLM-as-judge.
Optimize
Closed-loop improvement
Pipe failed traces into agent-opt: GEPA, PromptWizard, ProTeGi, and Bayesian search rewrite your prompts with proof of measured gains.
Simulate
Adversarial scenarios at scale
Generate hundreds of personas and run them through your Vapi agent before launch — text and voice, scripted or persona-driven.
Quickstart · <3 min
Instrument Vapi in three steps
-
Step 1
Install the traceAI package
One package per language, ships from PyPI, npm, and Maven Central.
-
Step 2
Register the trace provider
Set
FI_API_KEYandFI_SECRET_KEY, then callOpenAIInstrumentor().instrument(). -
Step 3
Run your existing Vapi app
No code changes. Traces appear in the Future AGI dashboard within seconds.
Install
pip install traceAI-openaiInstrument
from fi_instrumentation import register
from fi_instrumentation.fi_types import ProjectType
from traceai_openai import OpenAIInstrumentor
trace_provider = register(
project_type=ProjectType.OBSERVE,
project_name="VAPI_APP",
)
OpenAIInstrumentor().instrument(tracer_provider=trace_provider)
# Your existing Vapi code runs unchanged from here.
# Every call is now an OpenTelemetry span in Future AGI.Pick a recipe
