I've been using Claude Duet the last couple hours and I'll say this:

It's EXCELLENT

The multi tasking is probably the best in the space

You get one simple thread you can talk to, and as you give it commands and prompts, it automatically spins up tasks on a list for you

So instead of having to manage a ton of side chats that could get long or confusing, you have 1 chat, but it makes 'task' threads automatically that you can watch and monitor

This allows you to just keep brain dumping ideas and tasks into the one thread, and not have to worry about the agent getting confused. The agent just will manage all the tasks for you

Very similar to Claude Code's new 'projects' feature which was probably a beta test for this

The coding was great. Built me a bunch of PRs quickly I was able to review.

Proactivity was fantastic too. Came up with a bunch of tasks on its own and just asked me for the go ahead

As expected it's also fantastic to talk to. Claude has long been the best model to converse with (outside Opus 5) and the carries over to Claude Duet

Really pleased with the product, even in research preview. Very excited to see where it goes from here

Definitely sign up for the wait list
