Anthropic just released two new models for Claude 4: Opus 4 and Sonnet 4. Let's find out how good they are.

What are you using it for?

What s impressed you? What s broken?

I really like Claude, and I use it nearly daily. I feel like I'm probably missing out on taking full advantage of it though, because I've never used Projects.

Any tips for using it effectively? Is it better to keep the Projects very niche? Or does it work alright with general/ongoing work?

It's a hybrid reasoning model, producing near-instant responses or extended, step-by-step thinking. One model, two ways to think. We’re also releasing an agentic coding tool: Claude Code.

Claude can now search the web. Each response includes inline citations, so you can also verify the sources.

With the "think" tool, we're giving Claude the ability to include an additional thinking step—complete with its own designated space—as part of getting to its final answer.
