Saxon FletcherandCursor 9b17ce8f2c chore(studio): default assistant to GPT-5.6 Luna (#49749)
## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Feature / chore: hide assistant model selection in the UI and default
chats to GPT-5.6 Luna.

## What is the current behavior?

The assistant composer exposes a model picker. Paid orgs default to
`gpt-5.3-codex`; everyone else defaults to `gpt-5.4-nano`.

## What is the new behavior?

- The model picker is hidden in the assistant composer and Explorer
home.
- Chats default to `gpt-5.6-luna` with `reasoningEffort: medium`.
- Model selection plumbing is kept (registry, entitlements, `setModel`,
generate-v4 request body) so a requested model can still be honored when
provided.
- Other completion endpoints still use `gpt-5.4-nano`.

## Additional context

Model selector UI can be re-enabled by passing `selectedModel` /
`onSelectModel` to `AssistantChatForm`.

Writing components

Where to create your components

  • For components that declare the general structure and layout of a page:
    • /components/layouts/xxx
  • For components that are tightly coupled to a specific interface:
    • /components/interfaces/xxx
  • For components that are meant to be reusable across multiple pages:
    • /components/ui/xxx
  • Note: We're gradually moving files out of the to-be-cleaned folder into the respective folders as we refactor

Component structure

  • If a component has constants and utility methods that are tightly coupled to itself, keep them close to the component and enclose them in a folder with an index.tsx as an entry point
  • Otherwise it can just be a file on its own
  • For example:
    • components/ui
      - SampleComponentA
        - SampleComponentA.tsx
        - SampleComponentA.constants.ts
        - SampleComponentA.utils.ts
        - SampleComponentA.types.ts
        - index.ts
      - SampleComponentB.tsx
      

Template for building components


// Declare the prop types of your component
interface ComponentAProps {
  sampleProp: string
}

// Name your component accordingly — use a named export, not a default export
export const ComponentA = ({ sampleProp }: ComponentAProps) => {
  return <div>ComponentA: {sampleProp}</div>
}
