Production choice

Pick a default model. Keep fallback enabled.

TrustedRouter is useful when you know the model you want, but still need provider rollover, budget limits, usage records, and a prompt path you can verify.

Questions

Which should I use, DeepSeek: DeepSeek V3.2 or GPT 5.2?

Is DeepSeek: DeepSeek V3.2 or GPT 5.2 cheaper?

The current cheapest TrustedRouter route is $0.672/1M for DeepSeek: DeepSeek V3.2 and $16.5375/1M for GPT 5.2. The comparison uses current catalog prices and updates as provider pricing changes.

Is DeepSeek: DeepSeek V3.2 or GPT 5.2 faster?

Current measured p50 time to first token is 2279 ms for DeepSeek: DeepSeek V3.2 and not enough data for GPT 5.2. These are routed probe measurements, not vendor-advertised speeds, and update as new samples arrive.

Can I test DeepSeek: DeepSeek V3.2 and GPT 5.2 with the same API?

Yes. Use the same OpenAI-compatible TrustedRouter base URL and API key, then change only the model id between deepseek/deepseek-v3.2 and openai/gpt-5.2-2025-12-11. This makes side-by-side evals possible without maintaining two provider integrations.
