This adds a dialog that uses Chrome's built-in AI to set the colors, directions, etc.

You need to enable the AI feature using chrome://flags and enabling "Prompt API for Gemini Nano".

swift work! excited to try it

I'm checking the deploy preview in Canary with the experiment enabled, found the button (which is white on white atm) but have this error in my console?

Error initializing AI: NotAllowedError: Requires a user gesture when availability is "downloading" or "downloadable"

Will look deeper, but wanted to share those initial impressions

Fixed it locally, how do you prefer I get that code to you? Here's a summary:

What I changed:
•  Stop creating the model in onMount. We now only check availability there.
•  Added availability state to track 'downloadable' vs 'available'.
•  Added ensureSession(), which:
•  Runs only on a user action.
•  If availability is 'downloadable' or 'downloading', calls LanguageModel.create with a monitor to show download progress.
•  If 'available', creates the session immediately.
•  generateGradient() now calls ensureSession() first, so clicking Generate both satisfies the user-gesture requirement and handles any necessary model download before prompting.

I've got some button fixes too, mostly deleting styles.

Love it! I kinda figured this was more like a collab type deal. Thanks for joining in on the fun!

it works sometimes 😅

• transition hints seem to continuously be missed, even tho I added them to the zod schema
• it hallucinates some invalid colors sometimes

things that feel fixable tho!
