RecommendationApr 26, 2026
Claude Opus 4.7 moved into premium coding recommendations
Claude Opus 4.7 now leads premium coding recommendations because it has the strongest current public SWE-Bench Pro score among generally available models.
Claude Opus 4.7 costs $5 per million input tokens and $25 per million output tokens on the API, with cached input at $0.5 per million. A month of 10M input and 2M output tokens runs about $100.00 at list price, before any batch or caching discounts.
What is the context window of Claude Opus 4.7?
Claude Opus 4.7 has a 1M tokens context window, with up to 128k tokens of output per response. That is the total of prompt plus response the model can hold in one request.
What is the knowledge cutoff of Claude Opus 4.7?
Claude Opus 4.7's training data runs through January 31, 2026, and the model was released on April 16, 2026. For anything after that date it needs web search or documents in the prompt.
What is Claude Opus 4.7 best for?
Claude Opus 4.7 is best for highest-ceiling coding, agentic workflows, and deep research. It is a strong fit when that workflow matters more than the tradeoffs around premium pricing and deliberate speed.
When should I avoid Claude Opus 4.7?
You need cheaper high-volume throughput, image generation, or a workflow that must stay inside OpenAI tooling.
What is a cheaper alternative to Claude Opus 4.7?
GPT-5.1-Codex-Max (OpenAI) at $1.25/1M/1M input against Claude Opus 4.7's $5.00/1M/1M — roughly 63% less per token all in. The strongest choice for serious software engineering work, provided you can absorb the output-side pricing. Compare it first if Claude Opus 4.7's pricing is the thing stopping you.
What is a faster alternative to Claude Opus 4.7?
Claude Fable 5 — deliberate against Claude Opus 4.7's deliberate, with 1M tokens of context. Worth the swap when response time is what your users notice rather than the last few points of reasoning depth.
