Anthropic releases Claude 4.

Pricing remains consistent with previous Opus and Sonnet models: Opus 4 at $15/$75 per million tokens (input/output) and Sonnet 4 at $3/$15.

Claude Opus 4 is our most powerful model yet and the best coding model in the world. GitHub says Claude Sonnet 4 soars in agentic scenarios and will introduce it as the model powering the new coding agent in GitHub Copilot

Claude Code, now generally available, brings the power of Claude to more of your development workflow - new beta extensions for VS Code and JetBrains integrate Claude Code directly into your IDE. Beyond the IDE, we’re releasing an extensible Claude Code SDK, so you can build your own agents and applications using the same core agent as Claude Code.
