The essentials: Claude Code 2.1.197 integrates Claude Sonnet 5 with a 1M-token context window as the default model and offers promotional pricing of $2/$10 per million tokens through end of August.
Claude Code is being updated to version 2.1.197 and sets Claude Sonnet 5 as the new default model. The model features a native 1-million-token context window and is offered at a reduced price through August 31.
Version 2.1.197 of Claude Code introduces Claude Sonnet 5 as the new default model. The model features a native context window of 1 million tokens, making it suitable for extensive code analysis and multi-stage development tasks.
For CTOs and engineering teams, the expanded context size is relevant: it enables processing of larger code trees, more complex dependency structures, and longer project histories in a single request without repeatedly switching context. This reduces latency and error sources in human-model collaboration within IDE environments.
The pricing promotion through August 31, 2024 offers $2 per million input tokens and $10 per million output tokens. After the promotion expires, regular pricing will apply. The update is available at https://www.anthropic.com/news/claude-sonnet-5.
