Use DeepSeek models with FastClaw

Run FastClaw agents on DeepSeek — a built-in preset, thinking-mode support and per-agent model overrides for low-cost, capable agents.

01

One-line preset

The deepseek preset points at https://api.deepseek.com and reads DEEPSEEK_API_KEY from your environment.

02

Thinking mode handled

When DeepSeek requires reasoning_content to be passed back, FastClaw retries with it and sends it up front on later calls.

03

Cost-friendly defaults

Use DeepSeek as the default for busy chat bots and reserve pricier models for the agents that need them.

What you can do

  • Power high-volume bots on Telegram or WeCom with a low-cost model.
  • Mix DeepSeek with other model providers on a per-agent basis.
  • Keep reasoning output for memory extraction while the agent works through tool calls.

Set it up

  1. Open Console → Models, click Add provider, choose DeepSeek and paste your API key.
  2. Pick a DeepSeek model as the default or set it on one agent's Models tab.
  3. From the CLI:
export DEEPSEEK_API_KEY=sk-...
fastclaw agents init helper \
  --provider deepseek \
  --model deepseek/deepseek-chat \
  --api-key-env DEEPSEEK_API_KEY
