Anthropic released Claude Code v2.1.280, making Claude Opus5.5 the default model for Pro and Team Standard plans. This flagship model offers a 1 million token context window with aggressive pricing: $4 per million input tokens and $20 per million output tokens. The update shifts cheaper tier users to the premium Opus tier while maintaining beta pricing. The release also includes extensive bug fixes for API errors, security checks, and non-Latin script support, alongside new UI features in VS Code and cloud platforms. This move signals Anthropic's strategy to democratize top-tier AI intelligence for developers through lower costs and improved usability.
