Legacy

  • • Assistants API sunset per OpenAI migration guide
  • • AutoGen maintenance mode; Semantic Kernel names MAF as successor
  • • No other deprecation dates claimed

Current

  • • MAF adds workflows, checkpoints and human approval
  • • create_agent runs on LangGraph; StateGraph for custom flows
  • • LlamaIndex uses AgentWorkflow agents
