Summary
Claude Opus 4.7 is a legacy Opus release from April 2026, at $5 per million input tokens and $25 per million output tokens with a 1M-token context window. Two newer Opus models, 4.8 and 5, carry the same price.
Opus 4.7 was released on 16 April 2026 and introduced the tokenizer used by the models after it, which is why a 1M-token window holds roughly 555K words on this generation against roughly 750K words on earlier ones. It was succeeded first by Claude Opus 4.8 and then by Claude Opus 5, both at the same $5 / $25.
It accepts text and image input and returns text, with adaptive thinking and effort defaulting to high. This is also the first Claude model on which setting temperature, top_p or top_k to a non-default value returns a 400 error.
No deprecation has been announced. Anthropic commits to keeping Claude Opus 4.7 available until at least 16 April 2027.

Use it for
- Keep a pinned Opus 4.7 integration running while you evaluate a newer Opus release.
- Reproduce earlier results on a fixed snapshot when you need output to stay comparable over time.
Avoid it when
- You are starting a new integration; Claude Opus 5 costs the same $5 / $25 and has a May 2026 knowledge cutoff against January 2026 here.
- Your code sets temperature, top_p or top_k; non-default values return a 400 error on this model and later.
- Cost per call is a constraint; Claude Sonnet 5 offers the same 1M-token window at $2 / $10.
