This is one of those features that I can't imagine living without now. @OmidMogasemi and @julianfkelly have spent a ton of time getting the details right :)

Introducing Conductor code review! You can now comment on diffs and send it straight back to Claude without leaving the app. Like a PR review, but for the AI:

We loved this idea, live now :)
@OmidMogasemi @charliebholtz One more thing... I would love a Markdown viewer. When I have Claude write a plan to a markdown file, it would be nice if I could read it (maybe even in a popup window?) without the green background for a new file, and with the markdown rendered to make it easier to read

Conductor is growing fast, and we want YOU to join us! Conductor lets you run a bunch of coding agents in parallel. We’re used by engineers at YC, Linear, Vercel, Notion, Supabase, and many more. There’s a ton to build. In the next few years, humans will shift focus from direct

is there any reason to use Opus 4.1 now? tempted to remove Opus/Auto mode

"Despite my misgivings, over the past few weeks I’ve noticed myself quietly starting to embrace the parallel coding agent lifestyle. I can only focus on reviewing and landing one significant change at a time, but I’m finding an increasing number of tasks that can still be fired
I've become one of those people who run multiple coding agents at once - here are my notes on embracing the parallel coding agent lifestyle

Whenever you revert, we automatically send an attachment to Claude telling it that the changes were made on purpose, so it won't try and undo them

We've redesigned the new workspace page! Now you can change the name, target branch, link issues, and open in other apps from one view. Here's how it works:

Conductor users - what do you think of the git diff viewer? Love it? Find it buggy? Want to see it eradicated from the face of the Earth? I want to learn how you review and iterate on AI code changes. Schedule time with me and I'll send you a free hat 👇

1. Conductor ( https://t.co/wwmnB3bBKb) By FAR my favorite, and it just so happens to have been developed by a team from my YCombinator S24 batch, Melty. What I like about Conductor is that it is almost the exact workflow that I had envisioned in my head. It completely isolates

agreed. the best part of sonnet 4.5 is that my new default model is fast. opus 4.1 level smarts with sonnet level latency
still early, but i trust 4.5 sonnet more as a thought partner than gpt-5. i think a big part of this is how fast it is.

You can now setup Conductor to run via an alternate provider, like Bedrock, Vertex, or any Anthropic compatible URL!
