OpenAI's lightweight agent framework — a small set of primitives (Agents, Handoffs, Guardrails, Sessions); provider-agnostic via LiteLLM. Evolved from Swarm.
Type-safe agent framework from the Pydantic team — structured outputs, dependency injection, and model-agnostic agents.
Batteries-included agent runtime — built-in memory, knowledge/RAG, and AgentOS, a control plane you run in your own cloud. Formerly Phidata.
Graph-based orchestration for stateful, multi-actor agent workflows with explicit control flow and checkpointing.
