Which should you choose?
Which is better: Command A Translate, GPT-5 Chat or GPT-5-Codex?
GPT-5-Codex is the better all-round choice, scoring 42/100 against GPT-5 Chat (34) and Command A Translate (17). It leads on inputs & features. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.
Which is cheaper, Command A Translate, GPT-5 Chat or GPT-5-Codex?
GPT-5 Chat is cheaper at $1.25 input / $10.00 output per million tokens (median across 2 API providers). GPT-5-Codex costs $1.25 input / $10.00 output per million tokens (median across 3 API providers); Command A Translate costs $2.50 input / $10.00 output per million tokens (official Cohere API price). At a typical mix of three input tokens to one output token, that is $3.44 per million tokens for GPT-5 Chat versus $3.44 for GPT-5-Codex (1× as much) and $4.38 for Command A Translate (1.3× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. Command A Translate has not been scored yet, GPT-5 Chat has not been scored yet and GPT-5-Codex has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Command A Translate, GPT-5 Chat and GPT-5-Codex yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Note that GPT-5 Chat does not support tool calling, which most coding agents need.
Which has the bigger context window?
GPT-5 Chat and GPT-5-Codex have the largest context windows (400,000 and 400,000 tokens), against 8,000 for Command A Translate. Maximum output per response: Command A Translate up to 8,000, GPT-5 Chat up to 128,000, GPT-5-Codex up to 128,000 tokens.

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.
