Changes being requested

Add the new GPT-5.5 model aliases and dated snapshots to the SDK model type unions:

  • gpt-5.5
  • gpt-5.5-2026-04-23
  • gpt-5.5-pro
  • gpt-5.5-pro-2026-04-23

This updates ChatModel and the Responses compact model union so users can pass the new model IDs without relying on the loose string escape hatch.

Additional context & links

The public model docs list GPT-5.5 and GPT-5.5 pro aliases plus their dated snapshots:

Because this repository is generated, this may need to land through the upstream OpenAPI/Stainless generation flow rather than being merged as a manual patch.
