Our pick

38% cheaper input price, which compounds at scale
7.8× the context window — better for long documents and agents

Largest context window in the top tier (1M tokens). Tradeoff: pricier than DeepSeek and slower TTFT than GPT-5 — pick when whole-codebase or whole-PDF tasks matter.

Choose Mistral Large 3 instead if: Tradeoffs for this pair have not yet been documented. The quality difference may be small enough that workload fit, integration cost, and team familiarity decide the choice.
