Reality Composer Pro Assistant does not list GPT-5.6 models

First of all, great work on the new Reality Composer Pro! I'm really enjoying it.

Reality Composer Pro 3.0 (build 80.0.1.500.1/beta 4) currently shows GPT-5.5 as the newest OpenAI model in the Assistant model selector. The bundled configuration appears to contain a static model catalogue and does not include:

  • gpt-5.6-sol
  • gpt-5.6-terra
  • gpt-5.6-luna

Could Apple update Reality Composer Pro to support the current GPT-5.6 model family, or document whether users can add supported OpenAI model identifiers through the Custom Model Provider interface?

It would also be helpful to clarify whether the Assistant supports GPT-5.6's tool-calling and reasoning behavior through its current Chat Completions integration.

Thanks!
