LiteLLM ships LiteAgents preview to swap coding harnesses without a rewrite
LiteLLM’s Sept 25 preview SDK keeps your tools, MCP connections, and model config while you switch harnesses—Deep Agents, Pydantic AI, Claude Agent SDK, Codex, or OpenCode—via a Claude-Agent-SDK-style query() API. Optional Temporal durability covers long runs that must survive worker restarts.
