Our take
Written Aug 2, 2026Claude Opus Latest is Anthropic's flagship hosted-only model, released in April 2026, that can handle up to one million tokens in a single request and accepts text, images and files. It is positioned for deep analysis of long documents and complex multimodal inputs where output quality is expected to justify a premium price.
Choose this for book-length documents, large codebases or extended transcripts in a single prompt, or for multimodal analysis combining images, documents and text. Skip it if your budget cannot accommodate premium per-token pricing, or if you need validated benchmark scores.
The case for it
- One-million-token request limit, the highest figure we hold for this model.
- Accepts text, images and files together in a single prompt.
The case against it
- Premium per-token pricing with no cheaper tier or provider alternative available in our data.
- No benchmark scores, Elo ratings, or task-specific accuracy results in our data.
- Throughput and latency are unmeasured in our data.
How good is it?
We hold no score for this model.
We look for every model we track on every board we watch, and none of them has turned up Claude Opus Latest — so there is no intelligence, coding, agentic or writing score to show you, not a low one, none.
