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!

Hey @Conaaando,

There's currently no supported way for you to specify a model from a provider outside of the bundled configuration in the Reality Composer Pro Beta 4 Assistant. If you'd like us to consider adding the necessary functionality, please file an enhancement request using Feedback Assistant. Once you file the request, please post the FB number here.

If you're not familiar with how to file enhancement requests, take a look at Bug Reporting: How and Why?

Thanks,

Hi, @Vision Pro Engineer / Michael!

I am referring to the drop-down menu that appears after successfully connecting an AI provider (which I should have attached in my initial message):

That list seems to be static, but if we do something like:

curl https://api.openai.com/v1/models \
  -H "Authorization: Bearer $OPENAI_API_KEY" |
  jq -r '.data[].id' |
  grep 'gpt-5.6'

... we can see the latest models being provided by the API:

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

The dropdown in Reality Composer Pro should also include those, IMO.

I've submitted it here: FB24065533

Thanks!
