Gemini 3.1 Pro vs GPT-4.1

Google vs OpenAI · Prices checked 12 August 2026

The two are closer than they look: GPT-4.1 at $3.80 per million tokens blended, Gemini 3.1 Pro at $5.00, a 24 per cent difference. A single 100K-input, 10K-output job costs $0.280 on GPT-4.1 against $0.320 on Gemini 3.1 Pro.

Context is level at 1,000,000 tokens on each side.

Benchmarks

These two models do not currently report scores on any of the same benchmark suites, so there is no like-for-like capability comparison to show. Rather than pad the page with one-sided numbers, the benchmark leaderboards list every score we do hold.

What each model is for

Gemini 3.1 Pro

Google · Frontier

A mid-cycle upgrade to Gemini 3 Pro, released after rapid iteration on feedback from the November 3 Pro launch. Google positions it for the most complex tasks, with the clearest gains in ambitious agentic workflows. Keeps the 1M-token context window and full multimodal input.

  • Agentic workflow execution
  • Complex multi-step reasoning
  • 1M-token context
  • Text, image, audio and video input

GPT-4.1

OpenAI · Frontier

Long-context coding-focused GPT-4 successor with a 1M-token window. Aimed at developers who need predictable instruction following over very long inputs.

  • 1M context window
  • Strong coding
  • Better instruction following than GPT-4o
  • Cheap relative to GPT-4

Frequently asked questions

Which is cheaper, Gemini 3.1 Pro or GPT-4.1?

The two are closer than they look: GPT-4.1 at $3.80 per million tokens blended, Gemini 3.1 Pro at $5.00, a 24 per cent difference. A single 100K-input, 10K-output job costs $0.280 on GPT-4.1 against $0.320 on Gemini 3.1 Pro. Blended cost weights input at 70% and output at 30%; price your own token split for an exact answer, since the cheaper model on a blended basis is not always cheaper for your workload.

Which has the larger context window, Gemini 3.1 Pro or GPT-4.1?

Context is level at 1,000,000 tokens on each side. The context window caps everything in a single request: prompt, retrieved documents, conversation history and the model’s own output all share it.

Can I compare Gemini 3.1 Pro and GPT-4.1 on my own numbers?

Yes. Open both in the side-by-side comparison tool to see every field at once, or use the token calculator to price your actual prompt and monthly request volume against each model. Both are free and need no sign-up.
