Runchat Updates: February 20, 2026

🗄️ Runchat Script Browser in Rhino

• Every time you run a script from the code node in Rhino it saves a new version to your laptop
• You can browse these with the RunchatScript command. Then you can pick any version, see the code and re-run it.

🪲 Catch Rhino Bugs

• Any errors with your scripts are now logged to the Rhino console
• There's a new button in the code editor to send your console straight back to the coding agent so it can get on with fixing the bug. Easy peasy.

🖼️ Use images in the code agent chat and Open Router support

• You can paste images into the chat input and these are sent with your message, this is really handy for visually prompting the agent or for showing it how it's code failed to meet your expectations
• We now support prompt caching for anthropic models on open router, this makes them quite a bit cheaper to use.

What we're working on right now: More tutorials. Lots and lots more tutorials. We've done one series on using these new code features, and we'll be trying to add tutorials that focus on really specific use cases we're seeing a lot of people interested in. Looking forward to sharing these soon.
