Allocate Agent Models

Route for accuracy first, then reduce cost or latency only after representative evaluations show that a smaller model is reliable for that task class.

Keep facts and policy separate

Read references/openai-models.md when current model identity, availability, or API facts affect a decision.

Verified OpenAI facts as of 2026-08-11:

• gpt-5.6 currently aliases gpt-5.6-sol.
• Sol, Terra, and Luna are distinct models. More reasoning effort changes how a selected model works; it does not make Terra equivalent to Sol or Luna equivalent to Terra.

Treat every task matrix, fallback rule, failure count, and default below as local starting policy, not an OpenAI claim. These recommendations remain provisional until representative local evaluations support them.
