arkor dev

arkor dev boots Studio on http://localhost:4000. Studio is the local web UI where you trigger training runs, watch the run stream, and chat with the resulting model in the Playground.

​
Run it

pnpm dev
Open the URL the CLI prints. Click Run training to spawn a training run against src/arkor/index.ts. Live metrics stream in; once a checkpoint lands, the Playground lets you chat with it. arkor dev does not start a training run on its own. It only serves the UI plus the small loopback API the SPA talks to. Training is triggered from the UI.

​
Need a different port?

Pass --port: 
pnpm dev --port 5000
Add --open to open the browser automatically.
