Plugin[Beta]

The plugin allows users to rewrite Claude Code prompt and custom router. The plugin path is in $HOME/.claude-code-router/plugins. Currently, there are two demos available:

You need to move them to the $HOME/.claude-code-router/plugins directory and configure 'usePlugin' in $HOME/.claude-code-router/config.json，like this:

{
    "usePlugin": "gemini",
    "LOG": true,
    "OPENAI_API_KEY": "",
    "OPENAI_BASE_URL": "",
    "OPENAI_MODEL": ""
}

Some tips:

If you’re using the DeepSeek API provided by the official website, you might encounter an “exceeding context” error after several rounds of conversation (since the official API only supports a 64K context window). In this case, you’ll need to discard the previous context and start fresh. Alternatively, you can use ByteDance’s DeepSeek API, which offers a 128K context window and supports KV cache.

Note: claude code consumes a huge amount of tokens, but thanks to DeepSeek’s low cost, you can use claude code at a fraction of Claude’s price, and you don’t need to subscribe to the Claude Max plan.

Some interesting points: Based on my testing, including a lot of context information can help narrow the performance gap between these LLM models. For instance, when I used Claude-4 in VSCode Copilot to handle a Flutter issue, it messed up the files in three rounds of conversation, and I had to roll everything back. However, when I used claude code with DeepSeek, after three or four rounds of conversation, I finally managed to complete my task—and the cost was less than 1 RMB!
