GPT-5.1 Codex mini accepts text and images; Command A accepts text. GPT-5.1 Codex mini handles the widest range of inputs.

Are any of these open source?

Command A publishes its weights and can be self-hosted; GPT-5.1 Codex mini is proprietary.

Which is newer?

GPT-5.1 Codex mini is the newest, released Nov 13, 2025. Command A came out Mar 13, 2025. Knowledge cutoff: GPT-5.1 Codex mini Sep 30, 2024, Command A Jun 1, 2024.

How do you decide the winner?

Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Oct 4, 2026.
