Claude Opus 4.8
For work that gets reviewed: client deliverables, code you will ship, analysis someone will act on. Opus 4.8 catches its own mistakes.
[ Overview ]
Meet Claude Opus 4.8.
Claude Opus 4.8 is Anthropic's pick for complex, careful work, and it is the model to use when someone else is going to check what you produce. Agencies, consultants and technical teams reach for it when a quiet mistake would be expensive.
Use it for the client strategy doc that has to survive a boardroom, the multi-file code refactor, the audit of a competitor's positioning, or the long analysis where a plausible-but-wrong line would cost you the account. It is noticeably more willing to tell you when it is unsure than to guess confidently, which is exactly what you want in a deliverable.
Opus 4.8 sits between Sonnet 5 and Fable 5: deeper than Sonnet on hard problems, quicker to answer than Fable. Reach for it when the work has to hold up. It comes with HiggsChat alongside every other leading model and image and video generation, on one subscription.
