Claude 4 Is Finally Here

Anthropic's Claude Opus 4 is the most powerful model to date and one of the best coding models in the world.

Anthropic has finally released the much-anticipated Claude 4 AI models.

This release includes two new models:

• Claude Opus 4 — this is the world’s best coding model, with sustained performance on complex, long-running tasks and agent workflows.

• Claude Sonnet 4 — is a significant upgrade to Claude Sonnet 3.7, delivering superior coding and reasoning while responding more precisely to your instructions.

This is super exciting because Claude 3.7 Sonnet has been my go-to coding model in Cursor AI for months. It produces codes better than Gemini Pro and fixes bugs more efficiently. I’m really curious how the new one changes the vibe, especially for the side projects I’m working on right now.

Now let’s talk about what’s new and how these models actually perform.

What’s new in Claude 4?

Aside from the new model announcement, Anthropic also shared a couple of new capabilities:

• Extended thinking with tool use (beta): Claude can now switch between thinking and using tools like web search to give better answers.

• New model capabilities: Claude can now use tools at the same time, follow instructions more accurately, and remember key facts from local files to improve over time.

• Claude Code: This is open to all developers, with support for background tasks through GitHub Actions and built-in tools for VS Code and JetBrains to help with coding directly in your files.
