Deep dive
On shared benchmark coverage, SWE-bench Verified has Claude Opus 4.7 at 87.6 and Gemini 3 Pro at 76.2, with Claude Opus 4.7 ahead by 11.4 points; Google-Proof Q&A has Claude Opus 4.7 at 94.2 and Gemini 3 Pro at 91.9, with Claude Opus 4.7 ahead by 2.3 points; SWE-bench Pro has Claude Opus 4.7 at 64.3 and Gemini 3 Pro at 42.5, with Claude Opus 4.7 ahead by 21.8 points. The largest visible gap is 21.8 points on SWE-bench Pro, which matters most when that benchmark mirrors your workload. Treat isolated benchmark wins as directional, because provider routing, prompt style, and tool access can move real application results.
The capability footprint differs most on reasoning mode: Claude Opus 4.7 and structured outputs: Claude Opus 4.7. Both models share vision, multimodal input, function calling, and tool use, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
For cost, Claude Opus 4.7 lists $5/1M input and $25/1M output tokens on the cheapest tracked provider, while Gemini 3 Pro lists $1.25/1M input and $5/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Gemini 3 Pro lower by about $8.63 per million blended tokens. Availability is 7 providers versus 2, so concentration risk also matters.
Choose Claude Opus 4.7 when coding workflow support and broader provider choice are central to the workload. Choose Gemini 3 Pro when coding workflow support and lower input-token cost are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
