feat(api): Add gpt-5.5 model and tool name/namespace fields by apcha-oai · Pull Request #326 · openai/openai-ruby

apcha-oai · 2026-08-03T16:57:24Z

Summary

Introduce the gpt-5.5 model variant to public model enums and add optional name and namespace fields to function tool call input/output item models (beta and stable). Update constructors and type signatures to accept these new optional fields. These are additive, backward-compatible API changes.

Changes

Add a new model variant :gpt-5.5 to public model enums used by chat and responses-related parameter/model types (e.g., ChatModel, ResponseCreate/CompactParams, Beta response types).
Add optional String attributes name and namespace to function tool call output and input item models in both beta and stable namespaces (ResponseFunctionToolCallOutputItem and ResponseInputItem). These are exposed as accessors and accepted as optional constructor parameters.
Update public type/signature files (RBS/RBI) and tests to reflect the new optional name and namespace fields and the new gpt-5.5 model variant.

Pull request overview

This PR updates the Ruby SDK’s Responses/Conversations models and typing artifacts (RBS/RBI) to align with updated OpenAPI definitions, including new fields on function tool call outputs and refreshed model enums.

Changes:

Add name and namespace to function call output items across Responses, Conversations, and beta variants (models + tests).
Expand model enum/type lists to include :"gpt-5.5" across chat/responses request/response typing surfaces.
Add generated OpenAPI transformed reference tracking artifacts (api_reference/.gitattributes, .castiron.stats.yml).

sig/openai/models/responses/response_function_tool_call_output_item.rbs:63

to_hash is declared to always return non-nil created_by, name, and namespace, but these are optional fields and may be absent/unset at runtime. The return type should allow nil for these values to avoid misleading type guarantees.
sig/openai/models/responses/response_function_tool_call_output_item.rbs:14
In the RBS record type response_function_tool_call_output_item, the newly added name and namespace (and existing created_by) are typed as required non-nil String, but the Ruby model exposes them as optional fields (they can be absent and read back as nil). This makes the public type stricter than runtime behavior and contradicts the tests that treat these fields as nilable.
sig/openai/models/beta/beta_response_function_tool_call_output_item.rbs:17
In the RBS record type beta_response_function_tool_call_output_item, the newly added name and namespace (and existing created_by) are typed as required non-nil String, but these are optional fields on the Ruby model and can read back as nil when absent. This makes the public type stricter than runtime behavior.

The to_hash return type marks created_by, name, and namespace as non-nil String, but these fields are optional on the model and may be absent/unset (so accessing them from the returned hash can yield nil). This should be reflected in the RBI return type.
