Which is better: GPT-5.1 Chat, GPT-5.2 Chat or Gemini 2.5 Computer Use Preview?
GPT-5.1 Chat is the better all-round choice, scoring 38/100 against Gemini 2.5 Computer Use Preview (35) and GPT-5.2 Chat (35). 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-5.1 Chat, GPT-5.2 Chat or Gemini 2.5 Computer Use Preview?
GPT-5.1 Chat is cheaper at $1.25 input / $10.00 output per million tokens (median across 2 API providers). Gemini 2.5 Computer Use Preview costs $1.25 input / $10.00 output per million tokens (official Google API price); GPT-5.2 Chat costs $1.75 input / $14.00 output per million tokens (official OpenAI API price). At a typical mix of three input tokens to one output token, that is $3.44 per million tokens for GPT-5.1 Chat versus $3.44 for Gemini 2.5 Computer Use Preview (1× as much) and $4.81 for GPT-5.2 Chat (1.4× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. GPT-5.1 Chat has not been scored yet, GPT-5.2 Chat 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-5.1 Chat, GPT-5.2 Chat 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-5.1 Chat, GPT-5.2 Chat and Gemini 2.5 Computer Use Preview share the same 128,000-token context window. Maximum output per response: GPT-5.1 Chat up to 16,384, GPT-5.2 Chat up to 16,384, Gemini 2.5 Computer Use Preview up to 64,000 tokens.
Which can read images, PDFs, audio or video?
GPT-5.1 Chat accepts text and images; GPT-5.2 Chat 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?
No. GPT-5.1 Chat, GPT-5.2 Chat and Gemini 2.5 Computer Use Preview are proprietary and only available through APIs and apps.
Which is newer?
GPT-5.2 Chat is the newest, released Dec 11, 2025. GPT-5.1 Chat came out Nov 13, 2025; Gemini 2.5 Computer Use Preview came out Oct 7, 2025. Knowledge cutoff: GPT-5.1 Chat Sep 30, 2024, GPT-5.2 Chat Aug 31, 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.
