DeepSeek Agent Harness

What it is

DeepSeek's agent harness is an open-weight orchestration framework for building autonomous, multi-step agents — planning, tool-use, and memory in one package.

Why people use it

• Open-weight: self-hostable, no per-call API lock-in to a proprietary lab.
• Already a massive star count on launch — strong early adoption signal.
• Competitive with closed harnesses on agentic benchmarks at lower run cost.

Watch-outs

• New and fast-moving — APIs and patterns will shift. Pin versions.
• Ecosystem/tools are younger than LangGraph/CrewAI; expect rough edges.
• "Claude-killer" framing is hype until benchmarks + real workloads confirm it.
