Head-to-head · Updated March 2026
GPT-5.4 leads on coding benchmarks and has unique desktop computer-use capabilities. Gemini 3.1 Pro counters with a 2M token context window (7× larger), lower input pricing ($2 vs $2.50/1M), and stronger research benchmark performance. The choice comes down to your primary task: code and agent workflows favor GPT-5.4; research, large documents, and cost efficiency favor Gemini 3.1 Pro.
GPT-5.4
Best for agentic automation and desktop control workflows.
Gemini 3.1 Pro
Best for research and deep document analysis — 2M context at the best premium price.
| GPT-5.4 | Gemini 3.1 Pro | |
|---|---|---|
| Input cost / 1M tokens | $$2.50/1M | $$2.00/1M |
| Output cost / 1M tokens | $$15.00/1M | $$12.00/1M |
| Context window | 272k tokens | 2M tokens |

Which model wins for each use case — and why.
GPT-5.4 scores 74.9% on SWE-bench and has desktop computer-use for agentic coding. Gemini handles code but trails on the key coding benchmarks.
Gemini 3.1 Pro leads ARC-AGI-2 at 77.1% and has a 2M token context window for processing large research corpora in a single pass.
Gemini 3.1 Pro supports 2M tokens vs GPT-5.4's 272K — a 7× advantage for large document and codebase analysis.
Gemini 3.1 Pro costs $2/1M input vs GPT-5.4's $2.50/1M, and $12 vs $15/1M output — meaningfully cheaper at scale.
GPT-5.4 is the only frontier model with desktop computer-use via API. Gemini has no equivalent agentic capability for software automation.
