Anthropic is enhancing its Claude Opus model by offering a 1 million token context window by default for its Max, Team, and Enterprise plans. Additionally, starting June 15, 2026, eligible users on Pro, Max, Team, and Enterprise plans will receive a monthly credit for using the Claude Agent SDK. This credit covers usage for the SDK in custom projects, the `claude -p` command, and third-party applications, but does not apply to interactive use or web-based conversations. AI
