Claude Opus 5 is Anthropic’s flagship model for demanding reasoning, coding, and long-horizon agentic work. It is particularly strong at end-to-end software tasks, code review and bug finding, visual analysis of charts and documents, complex office deliverables, and coordinating parallel subagents. The model maintains strong instruction following and tool use across extended tasks, while remaining effective at lower effort settings for workloads that prioritize latency and token efficiency.
claude-opus-5 vs gemini-3.6-flash
Output tokens cost $25.00 per million on claude-opus-5 and $7.50 per million on gemini-3.6-flash. Input tokens cost $5.00 per million on claude-opus-5 and $1.50 per million on gemini-3.6-flash. Cached input tokens are billed at $0.50 per million on claude-opus-5 and $0.15 per million on gemini-3.6-flash. Context windows are 1,000,000 tokens on claude-opus-5 and 1,048,576 tokens on gemini-3.6-flash. First-token latency measured on AIHubMix is 1.4s on claude-opus-5 and 3.1s on gemini-3.6-flash. Measured output throughput is 56.7 tokens/s on claude-opus-5 and 123.8 tokens/s on gemini-3.6-flash.
Gemini 3.6 Flash provides sustained frontier-level intelligence optimized for real-world tasks at a higher speed and lower cost. Designed for the agentic era, it excels at code generation, agentic execution, and spatial reasoning. This model is particularly effective for rapid agentic loops involving complex coding cycles and iterations.
