Which should you choose?
Which is better: Command A Vision, GPT-5-Codex or GPT-5 Chat?
GPT-5-Codex is the better all-round choice, scoring 42/100 against GPT-5 Chat (34) and Command A Vision (22). 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 Vision, GPT-5-Codex or GPT-5 Chat?
GPT-5-Codex is cheaper at $1.25 input / $10.00 output per million tokens (median across 3 API providers). GPT-5 Chat costs $1.25 input / $10.00 output per million tokens (median across 2 API providers); Command A Vision 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-Codex versus $3.44 for GPT-5 Chat (1× as much) and $4.38 for Command A Vision (1.3× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. Command A Vision has not been scored yet, GPT-5-Codex has not been scored yet and GPT-5 Chat has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Command A Vision, GPT-5-Codex and GPT-5 Chat yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Note that Command A Vision and GPT-5 Chat does not support tool calling, which most coding agents need.
Which has the bigger context window?
GPT-5-Codex and GPT-5 Chat have the largest context windows (400,000 and 400,000 tokens), against 128,000 for Command A Vision. Maximum output per response: Command A Vision up to 8,000, GPT-5-Codex up to 128,000, GPT-5 Chat up to 128,000 tokens.
Which can read images, PDFs, audio or video?
Command A Vision accepts text and images; GPT-5-Codex accepts text and images; GPT-5 Chat accepts text and images. They handle the same number of input types.
Are any of these open source?
Command A Vision publishes its weights and can be self-hosted; GPT-5-Codex and GPT-5 Chat is proprietary.
Which is newer?
GPT-5-Codex is the newest, released Sep 15, 2025. GPT-5 Chat came out Aug 7, 2025; Command A Vision came out Jul 31, 2025. Knowledge cutoff: Command A Vision Jun 1, 2024, GPT-5-Codex Sep 30, 2024, GPT-5 Chat Sep 30, 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.
