Anthropic has released Claude Code v2.1.280, setting Claude Opus5.5 as the default Opus model. This model features a million-Token context window, with pricing for input, output, and cache reading remaining the same as the beta program, indicating that top-tier AI models are moving towards greater accessibility. The update also adjusts user subscription strategies, upgrading the default model for Pro and Team Standard plans from Sonnet to Opus, and providing transition options for existing users. Additionally, the new version introduces multiple optimizations and bug fixes in areas such as development experience, security mechanisms, multilingual support, terminal display, and voice dictation functionality, reflecting Anthropic's commitment to enhancing model performance while building a developer-friendly ecosystem.
