Which is better: GPT-5-Codex, Command A Plus or Gemini 2.5 Computer Use Preview?

GPT-5-Codex is the better all-round choice, scoring 42/100 against Command A Plus (35) and Gemini 2.5 Computer Use Preview (35). It leads on context window. 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, GPT-5-Codex, Command A Plus or Gemini 2.5 Computer Use Preview?

GPT-5-Codex is cheaper at $1.25 input / $10.00 output per million tokens (median across 3 API providers). Gemini 2.5 Computer Use Preview costs $1.25 input / $10.00 output per million tokens (official Google API price); Command A Plus 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 Gemini 2.5 Computer Use Preview (1× as much) and $4.38 for Command A Plus (1.3× as much).

Which scores higher on benchmarks?

There is no independent benchmark that covers all three models yet. GPT-5-Codex has not been scored yet, Command A Plus has not been scored yet and Gemini 2.5 Computer Use Preview has not been scored yet.

Which is better for coding?

There are no published SWE-bench Verified results for GPT-5-Codex, Command A Plus and Gemini 2.5 Computer Use Preview yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. All three support tool calling for agent workflows.

Which has the bigger context window?

GPT-5-Codex has the largest context window at 400,000 tokens, against 128,000 for Command A Plus and 128,000 for Gemini 2.5 Computer Use Preview. Maximum output per response: GPT-5-Codex up to 128,000, Command A Plus up to 64,000, Gemini 2.5 Computer Use Preview up to 64,000 tokens.

Which can read images, PDFs, audio or video?

GPT-5-Codex accepts text and images; Command A Plus accepts text and images; Gemini 2.5 Computer Use Preview accepts text and images. They handle the same number of input types.

Are any of these open source?

Command A Plus publishes its weights and can be self-hosted; GPT-5-Codex and Gemini 2.5 Computer Use Preview is proprietary.

Which is newer?

Command A Plus is the newest, released May 20, 2026. Gemini 2.5 Computer Use Preview came out Oct 7, 2025; GPT-5-Codex came out Sep 15, 2025. Knowledge cutoff: GPT-5-Codex Sep 30, 2024, Command A Plus Apr 1, 2025, Gemini 2.5 Computer Use Preview Jan 2025.

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.
