Head-to-head · Updated
Data verifiedClaude Opus 4.7 is the current coding leader by SWE-Bench Pro (64.3%) and the premium pick for agentic engineering work. Gemini 3.1 Pro wins on research depth and context window — its 2M token window is twice Opus's 1M, and it's cheaper at $2 vs $5/1M input. If your work is primarily coding, engineering agents, or high-stakes reasoning tasks, Opus 4.7 is worth the premium. If you process large research corpora, long documents, or run high-volume analytical workloads, Gemini 3.1 Pro is the smarter buy.

Which model wins for each use case — and why.
Claude Opus 4.7 leads SWE-Bench Pro at 64.3% — the highest public score on the hardest coding benchmark. For autonomous engineering agents, nothing currently beats it.
Gemini 3.1 Pro leads ARC-AGI-2 at 77.1% and has a 2M token context window. For processing large research corpora and document synthesis, Gemini is the stronger pick.
Gemini 3.1 Pro supports 2M tokens vs Opus 4.7's 1M — twice as much. For very large inputs, Gemini has the capacity advantage.
Gemini 3.1 Pro at $2/$12 per 1M tokens vs Claude Opus 4.7's $5/$25. Gemini is 2.5× cheaper on input — a significant difference for high-volume work.
Claude Opus 4.7 has strong vision capabilities with a 98.5% accuracy improvement in the latest generation. Gemini Pro also handles vision well but Claude's recent improvements give it the edge.
