Deep dive

The capability footprint differs most on reasoning mode: Claude Opus 4.6 and code execution: Claude Opus 4.6. 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 4.6 lists $5/1M input and $25/1M output tokens, while Gemini Deep Research Preview lists $2/1M input and $12/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Gemini Deep Research Preview lower by about $6 per million blended tokens. Availability is 4 providers versus 1, so concentration risk also matters.

Choose Claude Opus 4.6 when coding workflow support and broader provider choice are central to the workload. Choose Gemini Deep Research Preview when vision-heavy evaluation 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. This keeps the decision grounded in measurable tradeoffs instead of brand-level assumptions. It also helps separate model capability from provider packaging, which can change cost and latency.
