Summary
Claude Opus 5 is Anthropic's current top-tier general model, at $5 per million input tokens and $25 per million output tokens with a 1M-token context window and 128K max output. Anthropic positions it as its default choice for complex agentic coding and enterprise work.
Opus is the capability tier above Sonnet and below Fable in the Claude line. Claude Opus 5 was released on 24 July 2026 and succeeds Claude Opus 4.8 at the same price, with a newer May 2026 knowledge cutoff.
It accepts text and image input and returns text. Adaptive thinking is on by default and is steered with the effort parameter, which defaults to high; thinking can only be disabled at effort high or below. Setting temperature, top_p or top_k to a non-default value returns a 400 error, as on every Claude model from Opus 4.7 onwards.
No deprecation has been announced. Anthropic commits to keeping Claude Opus 5 available until at least 24 July 2027.

Use it for
- Run long agentic coding sessions across a large repository, using the 1M-token context window instead of chunking.
- Handle multi-step reasoning work where a mid-tier model needs several retries to get it right.
- Migrate off Claude Opus 4.8, 4.7, 4.6 or 4.5, all of which cost the same per token but carry older knowledge cutoffs.
- Generate long structured output up to 128K tokens in a single response.
Avoid it when
- You run high-volume, well-defined tasks; Claude Sonnet 5 costs $2 / $10 and Claude Haiku 4.5 costs $1 / $5 for the same kind of work.
- Your input includes audio or video; Claude Opus 5 accepts text and images only.
- Your code depends on temperature, top_p or top_k; non-default values return a 400 error.
- You need the lowest possible latency per call; Anthropic rates Opus 5 as moderate and Haiku 4.5 as the fastest in the line-up.
