CC Switch

Connect DeepSeek with CC Switch (recommended for beginners)

Don't want to hand-edit JSON, .env, or TOML? Use CC Switch.
CC Switch is a free desktop app: pick the DeepSeek preset → paste your API Key → enable — and CLI tools like Claude Code, OpenCode, Codex, and OpenClaw can use DeepSeek.

This guide is maintained by deepseekagent.io. CC Switch is a third-party open-source tool; we are not affiliated with its authors.

You are…	Recommendation
New to DeepSeek and afraid of breaking config files	Use CC Switch
Using Claude Code / OpenCode / Codex / OpenClaw	Prefer CC Switch

Before you start: DeepSeek API Key

Open the DeepSeek Platform
Create an API Key and copy it (shown once)
Make sure your account has usable quota

Website: ccswitch.ai

Step 2: Add DeepSeek as a provider

Open CC Switch
Click Add Provider
Choose the DeepSeek preset
Paste your API Key
Confirm (usually pre-filled by the preset):

Field	Typical value for Claude Code
Base URL	`https://api.deepseek.com/anthropic`
Main model	`deepseek-v4-pro[1m]`
Fast model	`deepseek-v4-flash[1m]`

Test connection if available, then Enable
Drag DeepSeek to the top of the provider list, or switch from the system tray

Step 3: Verify in your agent

Claude Code

cd your-project
claude

Send a short prompt. If it responds, you're connected.
Most tools need a terminal restart after switching.

OpenCode

opencode

Confirm DeepSeek is selected. Restart the terminal if you still see the old provider.

OpenClaw / Codex

Enable DeepSeek in CC Switch, restart the terminal, then run the CLI.
The official Codex guide involves Moon Bridge and extra setup — beginners should try CC Switch first, then read the manual guide if needed.

Manual config vs CC Switch

	Manual (our per-tool guides)	CC Switch
Difficulty	Medium — paths and field names	Low — GUI + presets
Best for	Full control	Getting started fast
Multi-model	Edit files each time	Tray / one-click switch
Our site	Explains why each field exists	Explains fastest path

They work together: CC Switch to get running, our guides when something breaks.

FAQ

Switched to DeepSeek but the CLI still uses the old model?
Close the terminal and open a new one. Claude Code sometimes hot-switches; most CLIs do not.

401 / auth errors?
Check the API Key and Base URL. For Claude Code, use https://api.deepseek.com/anthropic.
