DeepSeek

deepseek-chat for tool use; the reasoning model does not take tools, so it suits the router hop (AGENT_ROUTER_MODEL) rather than the domain agent.

bash

LLM_CHAIN=deepseek,anthropic   # failover to a second endpoint is one more name
LLM_DEEPSEEK_API_KEY=sk-…
LLM_DEEPSEEK_MODEL=deepseek-chat

Every endpoint takes the same knobs: LLM_<NAME>_TEMPERATURE (none omits it), LLM_<NAME>_BODY (JSON merged into every request), LLM_<NAME>_PRICE (input,cached,output per million, for the cost ledger), LLM_<NAME>_NOTES (a per-model notes file). Two models of one provider: LLM_FAST_PRESET=deepseek under another name. Environment has the full list.

Check it: npm run gateway, then curl localhost:8787/api/health — the llm.chain entry shows the endpoint, whether its key is set, and its state.
