04 — Questions

Which should you choose?

Which is better: GPT-5.4 nano or Gemini 2.5 Computer Use Preview?

GPT-5.4 nano is the better all-round choice, scoring 63/100 against Gemini 2.5 Computer Use Preview (35). It leads on price, inputs & features and 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-5.4 nano or Gemini 2.5 Computer Use Preview?

GPT-5.4 nano is cheaper at $0.20 input / $1.25 output per million tokens (official OpenAI API price). Gemini 2.5 Computer Use Preview costs $1.25 input / $10.00 output per million tokens (official Google API price). At a typical mix of three input tokens to one output token, that is $0.463 per million tokens for GPT-5.4 nano versus $3.44 for Gemini 2.5 Computer Use Preview (7.4× as much).

Which scores higher on benchmarks?

There is no independent benchmark that covers both models yet. GPT-5.4 nano has an ECI of 145.8 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-5.4 nano 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. Both support tool calling for agent workflows.

Which has the bigger context window?

GPT-5.4 nano has the largest context window at 400,000 tokens, against 128,000 for Gemini 2.5 Computer Use Preview. Maximum output per response: GPT-5.4 nano up to 128,000, Gemini 2.5 Computer Use Preview up to 64,000 tokens.

Which can read images, PDFs, audio or video?

GPT-5.4 nano 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-5.4 nano and Gemini 2.5 Computer Use Preview are proprietary and only available through APIs and apps.

Which is newer?

GPT-5.4 nano is the newest, released Mar 17, 2026. Gemini 2.5 Computer Use Preview came out Oct 7, 2025. Knowledge cutoff: GPT-5.4 nano 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.
