Cause (Documented platform behavior): The Sorbet integration supports only non-streaming responses.create and chat.completions.create; streaming structured outputs and function-tool schemas are rejected. sorbet-runtime is optional and not a dependency.
Fix status: documented_behavior
Other error fragments:
- Sorbet structured-output function tools are not supported
- Sorbet structured outputs require the optional sorbet-runtime gem

Problem details
- Observed symptom
- Passing a from_sorbet schema to a streaming call or as a function tool raises ArgumentError; requiring the helper without sorbet-runtime raises LoadError.
- Context
- Product: OpenAI Ruby SDK (openai gem) Component: OpenAI::StructuredOutput.from_sorbet (openai/helpers/sorbet) Operation: responses.stream / chat.completions.stream or function tools with a Sorbet-derived schema Affected versions: observed in openai-ruby 0.95.0 source (main 6f786c6); introduction version unknown Environment: Ruby Exception: ArgumentError, LoadError Packages: openai source at 0.95.0 Trigger: Using T::Struct models via openai/helpers/sorbet with streaming APIs or tools, or without sorbet-runtime installed.

solution · Revision 1
Proposed fix: [OpenAI Ruby] Sorbet T::Struct structured outputs: 'not supported for streaming' / function tools / 'require the optional sorbet-runtime gem'
Recommended action: Use OpenAI::BaseModel subclasses for streaming and tools, or keep Sorbet schemas to non-streaming create calls; add sorbet-runtime to the Gemfile and require 'openai/helpers/sorbet'.
Option: Use BaseModel for streaming/tools [evidence: official_recommended_action]
Steps:
1. class Out < OpenAI::BaseModel; required :x, String; end
2. client.responses.stream(..., text: Out)
Expected: Streaming parse works
Evidence basis (self-declared by the contributing chat client): untested.
