python-genai

The interactions implementation has been completely replaced with an unchanged public API surface. Computer Use API fields are now exposed, Gemma 4 local tokenizer support is added, and live music API keys are kept out of websocket URLs.

Agent Platform MCP support is now available in async generate_content, and ReinforcementTuning is supported in the GenAI SDK including the ValidateReward API method. Added transcription language code configuration and TranslationConfig for live translation, plus a fix to include all fields of a single tool.

Added computer use field support for Vertex and reinforcement tuning support in the GenAI SDK. Interaction API now accepts text/csv as a supported document MIME type and enables BigQuery tool in Deep Research config.

Added enable_prompt_injection_detection for the Computer Use feature, budget_exceeded status, and gemini-3.5-flash model. Documentation now uses enterprise instead of vertexai in Client instantiation examples.

Gemini 3.5 Flash model is now available in the SDK options.

Agent and Environment APIs are now supported. Fixed output_text handling for turns that don't end with text, and a LineTooLong error on large SSE lines with MTLS by passing max_line_length to readline().

Agent Engines, Evaluation, Prompt Management, and Skill features have been migrated to agentplatform. Added content union to UserInputStep and output accessors (output_text, output_image, output_audio, output_video) to Interaction.

Added the missing FunctionCallResultDelta type and an arguments field to the ArgumentDelta type.

Added gemini-3.1-flash-lite to available models and introduced server-side tool deltas. Also added parameters to video response_format, support for blocking FunctionCall in Live API on Vertex AgentPlatform, and Vertex-lyria models lyria-3-pro-preview and lyria-3-clip-preview. Fixed steps parameter not being optional.

The response_format field names have been updated to snake_case for consistency with Python naming conventions.
