Sonnet 4.6 is here. It's our most capable Sonnet model by far, approaching Opus-class capabilities in many areas. Very excited for folks to try this one out. The performance jump over Sonnet 4.5 (which was released just over four months ago) is quite insane.

Anthropic launches Claude Sonnet 4.6 with improvements in coding, computer use, instruction following, and more; it features a 1M token context window in beta

Claude Sonnet 4.6 is our most capable Sonnet model yet.  It's a full upgrade of the model's skills across coding, computer use …

Underrated dev upgrade from today's launch: Claude's web search and fetch tools now write and execute code to filter results before they reach the context window. When enabled, Sonnet 4.6 saw 13% higher accuracy on BrowseComp while using 32% fewer input tokens.

Less than a year and a half ago computer use was barely even a thing and now we're near human-level capability. Another reminder that things are improving very fast.

Opus 4.6 is here. The jump in autonomy is real. The biggest shift for me personally has been learning to let it run. Give it the context, step away, and come back to something pretty amazing. The way we work alongside models is starting to completely change.

>Opus 4.5 “seems to be able to vibe code forever” I've found this to be very true. Much more to come here but basically you can set-and-forget this model as it works on coding task for you in the background. Feels like we hit a step change.
