DeepSeek

DeepSeek provides powerful AI models with an OpenAI-compatible API.

Property	Value
Provider	`deepseek`
Auth	`DEEPSEEK_API_KEY`
API	OpenAI-compatible
Base URL	`https://api.deepseek.com`

Getting started

Get your API key

Create an API key at platform.deepseek.com.

Run onboarding

fluffbuzz onboard --auth-choice deepseek-api-key

This will prompt for your API key and set deepseek/deepseek-chat as the default model.

Verify models are available

fluffbuzz models list --provider deepseek

Non-interactive setup

For scripted or headless installations, pass all flags directly:

fluffbuzz onboard --non-interactive \
  --mode local \
  --auth-choice deepseek-api-key \
  --deepseek-api-key "$DEEPSEEK_API_KEY" \
  --skip-health \
  --accept-risk

If the Gateway runs as a daemon (launchd/systemd), make sure DEEPSEEK_API_KEY is available to that process (for example, in ~/.fluffbuzz/.env or via env.shellEnv).

Built-in catalog

Model ref	Name	Input	Context	Max output	Notes
`deepseek/deepseek-chat`	DeepSeek Chat	text	131,072	8,192	Default model; DeepSeek V3.2 non-thinking surface
`deepseek/deepseek-reasoner`	DeepSeek Reasoner	text	131,072	65,536	Reasoning-enabled V3.2 surface

Both bundled models currently advertise streaming usage compatibility in source.
