Anthropic Unveils Claude Sonnet 4.6 With Advanced Coding and Computer Use
Anthropic releases Claude Sonnet 4.6, its most capable Sonnet model to date, featuring major upgrades in coding, agent planning, and computer use. The new model offers a one-million token context window and replaces Sonnet 4.5 as the default for free and pro users at the same price point.
Anthropic introduces Claude Sonnet 4.6 as a comprehensive upgrade across coding, computer use, long-context reasoning, agent planning, and knowledge work. The model features a beta one-million token context window and replaces Claude Sonnet 4.5 as the default option for users on the Free and Pro plans within claude.ai and Claude Cowork. Pricing stays consistent with the previous generation at $3 per million input tokens and $15 per million output tokens.
Developers with early access strongly prefer Sonnet 4.6 over its predecessor and frequently choose it over the older Claude Opus 4.5 for complex tasks. The model delivers performance on real-world, economically valuable office tasks that previously requires an Opus-class model. Additionally, Sonnet 4.6 demonstrates a major leap in computer use skills, allowing it to interact with legacy software through standard mouse clicks and keyboard typing instead of requiring custom-built API connectors.
Extensive safety evaluations show that Sonnet 4.6 is as safe as or safer than Anthropic's recent models, with researchers noting its warm, honest, and prosocial character alongside strong safety behaviors. The advancement in computer use highlights significant progress since Anthropic first introduced a general-purpose computer-using model in October 2024, steadily improving on standard benchmarks like OSWorld that test AI across real software environments.
