Update Pydantic AI samples to non-deprecated google: model prefix#785
Merged
Conversation
Pydantic AI renamed the Gemini API provider prefix. google-gla: now emits a PydanticAIDeprecationWarning and is removed in v2.0, so switch the sample agents to the google: prefix (same free-tier Gemini API-key flow). The gemini-2.5-flash model id is unchanged and still current. Matches the corresponding fix in the Pydantic AI tutorial and was flagged by a reader comment.
