Claude Opus 4.8
Claude Opus 4.8 is Anthropic's flagship-class model, widely regarded as the strongest all-rounder for real coding and agentic work, plus careful analysis and writing. It has a 1M-token context window, takes images, and offers an adjustable 'effort' dial to trade speed for depth on hard problems. It is a closed cloud model — no self-hosting — but the quality ceiling and reliability on long, multi-step tasks are why it is the default frontier pick for serious work. Anthropic's even-higher Fable 5 sits above it.
What it can help with
- code generation
