Anthropic has introduced Claude Sonnet 4.6, describing it as the most capable version of its Sonnet series so far. The new model is designed to deliver improved performance across several areas, including coding, long-context reasoning, agent planning, knowledge work and more. It also comes with a beta feature that allows it to handle up to 1 million tokens of context.
SurveyWith this release, Claude Sonnet 4.6 replaces the previous Sonnet version as the default model for users on Free and Pro plans in claude.ai and Claude Cowork. Despite the upgrade, pricing remains unchanged from the earlier version, starting at $3/$15 per million tokens. This means users get improved capabilities without paying more.

One of the biggest improvements is in coding. According to Anthropic, developers who tested the model early found it more consistent and better at following instructions than earlier Sonnet versions. According to the company, Claude Sonnet 4.6 also shows a major improvement in computer use skills as compared to the previous Sonnet models.
Safety was another focus during development. The company conducted extensive evaluations and reported that the model meets or exceeds the safety standards of its recent AI systems. Anthropic said, “Our safety researchers concluded that Sonnet 4.6 has ‘a broadly warm, honest, prosocial, and at times funny character, very strong safety behaviors, and no signs of major concerns around high-stakes forms of misalignment.'”
