How they compare

Which model wins for each use case — and why.

CodingGPT-5.4 wins

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.

ResearchGemini 3.1 Pro wins

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.

Context WindowGemini 3.1 Pro wins

Gemini 3.1 Pro supports 2M tokens vs GPT-5.4's 272K — a 7× advantage for large document and codebase analysis.

PriceGemini 3.1 Pro wins

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.

Agentic TasksGPT-5.4 wins

GPT-5.4 is the only frontier model with desktop computer-use via API. Gemini has no equivalent agentic capability for software automation.

Which should you pick?

Pick GPT-5.4 if…

  • You're building agentic workflows that need desktop or browser control via API
  • Coding quality is your priority and you're already in the OpenAI ecosystem
  • You need the full OpenAI toolset: Assistants, plugins, function calling

Pick Gemini 3.1 Pro if…

  • You regularly analyze large documents or research corpora exceeding 272K tokens
  • Cost efficiency matters — Gemini is ~20% cheaper per input token
  • Research synthesis, reasoning depth, and long-context work are your core tasks
  • You use Google Workspace and want native AI integration

The case for each model

What each one is genuinely good at, where it falls down, and when we would steer you away from it.

GPT-5.4

OpenAI

Against Gemini 3.1 Pro it costs about 20% more per token.

OpenAI's latest flagship with unique desktop-control capabilities — it can see your screen, click, and navigate apps via the API.

What people actually use it for

  • Building agents that browse the web and operate desktop software autonomously via the API
  • Complex multi-step reasoning for financial modeling and decision analysis
  • Autonomous test-run-debug loops for coding with computer-use control

Where it wins

  • Only frontier model that can control a desktop via API (click, type, navigate)
  • Strong at multi-step agentic tasks and autonomous workflows
  • Competitive coding performance with 74.9% SWE-bench score

Where it falls down

  • Claude Opus 4.7 and GPT-5.5 now outperform it on current premium coding benchmarks
  • Smaller context window (272K) vs Gemini 3.1 Pro (2M) for research

Skip it if

You need the highest current coding benchmark scores — Claude Opus 4.7 and GPT-5.5 are newer premium picks.

Our verdict

Best choice when you need a model that can operate software autonomously at the older GPT-5.4 price tier. For current premium coding quality, Claude Opus 4.7 leads.

Gemini 3.1 Pro

Google

Against GPT-5.4 it costs about 20% less per token and takes 7x the context.

Google's flagship with the largest context window of any frontier model at 2M tokens, Deep Think reasoning, and the best price-to-performance among premium models.

What people actually use it for

  • Analyzing entire contracts, codebases, or research corpora in a single 2M-token prompt
  • Due diligence synthesis across large sets of financial documents or legal agreements
  • Multi-step reasoning across dense technical specifications with Deep Think mode

Where it wins

  • 2M token context window — the largest of any frontier model
  • Leads ARC-AGI-2 reasoning benchmark at 77.1%
  • Best price-to-performance among premium models at $2/$12 per 1M tokens

Where it falls down

  • Slower than Flash for everyday lightweight tasks
  • Claude Sonnet 4.6 is better for writing quality

Skip it if

Your primary use case is writing quality or agentic coding — Claude wins both.

Our verdict

The best research and long-context model available. Handles entire codebases, legal documents, and large datasets in a single pass — at a lower price than GPT-5.4 or Claude Sonnet 4.6.
