Description
The public GPT-5.5 model docs now exist at:
https://developers.openai.com/api/docs/models/gpt-5.5
However, the OpenAPI spec does not currently include gpt-5.5 in ModelIdsShared.
Current spec location:
https://github.com/openai/openai-openapi/blob/master/openapi.yaml
Relevant current state:
ModelIdsShared.example is still gpt-5.4- the enum includes
gpt-5.4, gpt-5.4-mini, gpt-5.4-nano, etc.
gpt-5.5 is not present anywhere in the spec
This also appears to propagate to generated SDKs. For example, openai-node currently has Shared.ChatModel generated with gpt-5.4 entries but no gpt-5.5 entry:
https://github.com/openai/openai-node/blob/master/src/resources/shared.ts
Expected
If gpt-5.5 is available for the OpenAI API, it should be included in the OpenAPI model enum so generated SDKs expose it in their model literal unions / autocomplete.
Notes
The SDKs still allow arbitrary strings in some request params, so this is mainly a generated type / autocomplete consistency issue rather than a hard runtime blocker.
