Eduard van Valkenburg 0521f5bed8 Python: [BREAKING] Simplify API: ChatAgent -> Agent, ChatMessage -> Message (#3747)
* [BREAKING] Rename ChatAgent -> Agent, ChatMessage -> Message, ChatClientProtocol -> SupportsChatGetResponse

Simplify the public API by removing redundant 'Chat' prefix from core types:
- ChatAgent -> Agent
- RawChatAgent -> RawAgent
- ChatMessage -> Message
- ChatClientProtocol -> SupportsChatGetResponse

Also renamed internal WorkflowMessage (was Message in _runner_context) to avoid collision.

No backward compatibility aliases - this is a clean breaking change.

* [BREAKING] Rename Agent chat_client parameter to client

* Fix rebase issues: WorkflowMessage references and broken markdown links

* Fix formatting and lint issues from code quality checks

* Fix import ordering in workflow sample files

* fixed rebase

* Fix test failures: use WorkflowMessage and A2AMessage after ChatMessage→Message rename

- Replace Message(data=..., source_id=...) with WorkflowMessage(...) in workflow tests
- Fix isinstance check in A2A agent to use A2AMessage instead of Message
- Fix import in test_workflow_observability.py (Message→WorkflowMessage)

* Fix lint, fmt, and sample errors after ChatMessage→Message rename

- Auto-fix 70+ ruff lint issues across samples (ChatMessage→Message refs)
- Fix HostedVectorStoreContent→Content.from_hosted_vector_store in file search sample
- Fix _normalize_messages→normalize_messages in custom agent sample
- Fix context.terminate→raise MiddlewareTermination in middleware samples
- Fix with_update_hook→with_transform_hook in override middleware sample
- Add TOptions_co import back to custom_chat_client sample
- Add noqa for FastAPI File() default in chatkit sample
- Fix B023 loop variable capture in weather agent sample

* fix: update Agent constructor calls from chat_client to client in declaration-only tool tests

* fix: add register_cleanup to devui lazy-loading proxy and type stub

* fixed tests and updated new pieces

* fix agui typevar

* fix merge errors

* fix merge conflicts

* fiux merge

* Remove unused links

openai_assistants_with_existing_assistant.py Working with pre-existing assistants using get_agent() and as_agent() methods.
openai_assistants_with_explicit_settings.py Configuring OpenAIAssistantProvider with explicit settings including API key and model ID.
openai_assistants_with_file_search.py Using HostedFileSearchTool with OpenAIAssistantProvider for file search capabilities.
openai_assistants_with_function_tools.py Function tools with OpenAIAssistantProvider at both agent-level and query-level.
openai_assistants_with_response_format.py Structured outputs with OpenAIAssistantProvider using Pydantic models.
openai_assistants_with_thread.py Thread management with OpenAIAssistantProvider for conversation context persistence.
openai_chat_client_basic.py The simplest way to create an agent using Agent with OpenAIChatClient. Shows both streaming and non-streaming responses for chat-based interactions with OpenAI models.
openai_chat_client_with_explicit_settings.py Shows how to initialize an agent with a specific chat client, configuring settings explicitly including API key and model ID.
openai_chat_client_with_function_tools.py Demonstrates how to use function tools with agents. Shows both agent-level tools (defined when creating the agent) and query-level tools (provided with specific queries).
openai_chat_client_with_local_mcp.py Shows how to integrate OpenAI agents with local Model Context Protocol (MCP) servers for enhanced functionality and tool integration.
openai_chat_client_with_thread.py Demonstrates thread management with OpenAI agents, including automatic thread creation for stateless conversations and explicit thread management for maintaining conversation context across multiple interactions.
openai_chat_client_with_web_search.py Shows how to use web search capabilities with OpenAI agents to retrieve and use information from the internet in responses.
openai_chat_client_with_runtime_json_schema.py Shows how to supply a runtime JSON Schema via additional_chat_options for structured output without defining a Pydantic model.
openai_responses_client_basic.py The simplest way to create an agent using Agent with OpenAIResponsesClient. Shows both streaming and non-streaming responses for structured response generation with OpenAI models.
openai_responses_client_image_analysis.py Demonstrates how to use vision capabilities with agents to analyze images.
openai_responses_client_image_generation.py Demonstrates how to use image generation capabilities with OpenAI agents to create images based on text descriptions. Requires PIL (Pillow) for image display.
openai_responses_client_reasoning.py Demonstrates how to use reasoning capabilities with OpenAI agents, showing how the agent can provide detailed reasoning for its responses.
openai_responses_client_streaming_image_generation.py Demonstrates streaming image generation with partial images for real-time image creation feedback and improved user experience.
openai_responses_client_with_agent_as_tool.py Shows how to use the agent-as-tool pattern with OpenAI Responses Client, where one agent delegates work to specialized sub-agents wrapped as tools using as_tool(). Demonstrates hierarchical agent architectures.
openai_responses_client_with_code_interpreter.py Shows how to use the HostedCodeInterpreterTool with OpenAI agents to write and execute Python code. Includes helper methods for accessing code interpreter data from response chunks.

Environment Variables

Make sure to set the following environment variables before running the examples:

  • OPENAI_API_KEY: Your OpenAI API key

  • OPENAI_RESPONSES_MODEL_ID: The OpenAI model to use (e.g., gpt-4o, gpt-4o-mini, gpt-3.5-turbo)
  • For image processing examples, use a vision-capable model like gpt-4o or gpt-4o-mini

Optionally, you can set:

  • OPENAI_ORG_ID: Your OpenAI organization ID (if applicable)
  • OPENAI_API_BASE_URL: Your OpenAI base URL (if using a different base URL)

Optional Dependencies

Some examples require additional dependencies:

  • Image Generation Example: The openai_responses_client_image_generation.py example requires PIL (Pillow) for image display. Install with:
    # Using uv
    uv add pillow
    
    # Or using pip
