Description
Claude Sonnet 5 is the newest addition to Anthropic's Sonnet model family, designed as a drop-in upgrade for Claude Sonnet 4.6. This model introduces several key changes, including adaptive thinking enabled by default, which enhances its ability to process complex tasks more efficiently. Users should note that manual extended thinking has been removed, and setting sampling parameters like temperature, top_p, or top_k to non-default values will result in a 400 error.

The model supports a 1M token context window, which is both the default and maximum capacity, allowing for extensive input processing. However, due to a new tokenizer, the same input text now produces approximately 30% more tokens compared to Claude Sonnet 4.6. This change affects token counts and context window capacity, necessitating a review of token budgets and max_tokens limits for existing workloads.
Claude Sonnet 5 also introduces real-time cybersecurity safeguards, a first for the Sonnet-tier models. These safeguards ensure that requests involving prohibited or high-risk cybersecurity topics are refused, providing an additional layer of security for sensitive applications.
In terms of pricing, Claude Sonnet 5 is more cost-effective than its predecessor, with input tokens priced at $2 per million and output tokens at $10 per million. Despite the lower per-token pricing, the increased token count means that the cost of equivalent requests does not decrease proportionally.
Available on Claude API, AWS, Google Cloud, and Microsoft Foundry, Claude Sonnet 5 is accessible to a wide range of users. It supports zero data retention for organizations with ZDR agreements, ensuring data privacy and compliance. Overall, Claude Sonnet 5 is a significant upgrade for users seeking enhanced capabilities without transitioning to an Opus-class model.
