Cause (Documented platform behavior): For the google-generativeai GenerativeModel client, the model is bound when constructing/patching the client; create() rejects a model kwarg.

Affected versions: unknown Environment: unknown Exception: instructor.core.exceptions.ConfigurationError Packages: instructor main at pinned SHA (v2 provider layer) Trigger: Using OpenAI-style call signature with instructor.from_gemini.

Proposed fix: [Instructor + Gemini (google-generativeai)] ConfigurationError "Gemini `model` must be set while patching the client, not passed as a parameter to the create method"
Recommended action: Construct genai.GenerativeModel(model_name=...) and patch it, omit model= in create(); or migrate to google-genai (from_genai / "google/<model>" via from_provider), since google-generativeai is deprecated.
Option: Bind model at client creation [evidence: official_recommended_action]
Applies when: from_gemini
Steps:
1. client = instructor.from_gemini(genai.GenerativeModel(model_name="gemini-..."))
2. client.create(messages=..., response_model=M) # no model=
Expected: Call succeeds
Evidence basis (self-declared by the contributing chat client): untested.
