Accounts Fireworks Models GPT Oss 120B (Fireworks AI, 131,072-token context) versus Baidu Ernie 4.5 VL 28B A3b Thinking (Novita AI, 131,072-token context). Accounts Fireworks Models GPT Oss 120B is cheaper by 4% on a blended token mix. Baidu Ernie 4.5 VL 28B A3b Thinking uniquely supports parallel tool calls and vision input. Use the live calculator below to plug your real usage shape into both, then route the winner via Agent Command Center for shadow A/B without code changes.

Bottom line — Accounts Fireworks Models GPT Oss 120B vs Baidu Ernie 4.5 VL 28B A3b Thinking

Accounts Fireworks Models GPT Oss 120B and Baidu Ernie 4.5 VL 28B A3b Thinking are priced within 4% of each other, so cost alone is not the deciding factor. The comparison comes down to capabilities, context window, and benchmark performance on the specific task shape your workload demands.

On capability surface area, the models diverge: Baidu Ernie 4.5 VL 28B A3b Thinking supports parallel tool calls where the other does not; Baidu Ernie 4.5 VL 28B A3b Thinking supports vision input where the other does not. These differences are binary — either your workload needs the capability or it does not. Check whether any critical path in your agent pipeline depends on a capability only one model provides before committing to a migration.

For teams evaluating both models, the recommended path is a shadow A/B test: route production traffic through an OpenAI-compatible gateway, mirror a percentage to the candidate model, score both responses with an automated evaluator (faithfulness, tool-call correctness, latency), and compare cohort-level metrics over two weeks. Future AGI Agent Command Center supports this pattern with a single `base_url` change and built-in evaluators from the ai-evaluation SDK.

Cost at scale: monthly spend at three usage volumes

Estimated monthly cost assuming 1,000 input + 200 output tokens per request — a realistic chat-agent shape. Adjust your own usage in the calculator at the top of this page for an exact number.

When to choose which

Picked from the data above — not vendor marketing. Match the rules to your workload, not the other way around.

Choose Baidu Ernie 4.5 VL 28B A3b Thinking

Your inputs include screenshots, diagrams, or product photos — Baidu Ernie 4.5 VL 28B A3b Thinking accepts image input natively, the other doesn't.

Capability diff — what you gain and lose on the swap

A specific list of what each model has that the other doesn't. If your workload depends on a row in Only Accounts Fireworks Models GPT Oss 120B, switching to Baidu Ernie 4.5 VL 28B A3b Thinking means re-architecting that path (and vice versa).

Migration considerations

Concrete differences to wire through your stack before you flip traffic from one to the other.

  • Max output tokens differ: 32,768 on Accounts Fireworks Models GPT Oss 120B vs 65,536 on Baidu Ernie 4.5 VL 28B A3b Thinking. Long-form generation tasks may truncate differently — adjust streaming UI and chunking accordingly.
  • Baidu Ernie 4.5 VL 28B A3b Thinking has capabilities Accounts Fireworks Models GPT Oss 120B lacks: Parallel tool calls, Vision input. Worth wiring through the agent design before commit.
  • Provider changes from Fireworks AI to Novita AI. API authentication, rate-limit policy, regional availability, and billing all shift. Most teams route through an OpenAI-compatible gateway (e.g., Future AGI Agent Command Center) so the swap is a single `base_url` change instead of an SDK rewrite.

How to A/B test Accounts Fireworks Models GPT Oss 120B vs Baidu Ernie 4.5 VL 28B A3b Thinking in production

If you're stuck between the two, run them side-by-side on real traffic. Four steps the Future AGI team uses internally:

  1. 1. Point your existing OpenAI SDK at https://gateway.futureagi.com/v1. No code change beyond base_url and a virtual key.
  2. 2. Mark Accounts Fireworks Models GPT Oss 120B primary, mirror 20% of traffic to Baidu Ernie 4.5 VL 28B A3b Thinking in shadow mode. Both responses are logged; only the primary is served to users.
  3. 3. Score every shadow response with an evaluator — faithfulness, tool-call correctness, response latency, cost. Built-in evaluators in ai-evaluation cover the common axes.
  4. 4. Compare cohort-level metrics after two weeks. Switch primary when the candidate wins on what matters to your workload — and stays within your latency budget.

Baidu Ernie 4.5 VL 28B A3b Thinking accepts native image input. Accounts Fireworks Models GPT Oss 120B does not — you would need to route image-heavy workloads through Baidu Ernie 4.5 VL 28B A3b Thinking or add a separate vision model in front of Accounts Fireworks Models GPT Oss 120B.

How do I A/B test Accounts Fireworks Models GPT Oss 120B against Baidu Ernie 4.5 VL 28B A3b Thinking in production?

Route both through an OpenAI-compatible gateway like Future AGI Agent Command Center with shadow mode enabled. Send 100% of traffic to your primary model, mirror 10–20% to the candidate, score every response with an evaluator (faithfulness, tool-call correctness, response time), and compare cohort-level metrics for two weeks. Switch when the candidate wins on the metrics that matter to your workload and stays within your latency budget.
