Claude Code

For routing rules, see Routing & Protocols. For available model IDs, see List Models. Claude Code works with Anthropic Messages-compatible gateways. PipeLLM supports that in two ways:

Use case	Base URL	Why
Call Claude models	`https://api.pipellm.ai`	Use PipeLLM’s native Anthropic-compatible route
Keep Claude Code, call GPT or Gemini	`https://api.pipellm.ai/anthropic`	Use the Anthropic converter route

Config File

Claude Code reads configuration from ~/.claude/settings.json.

Remove conflicting shell variables before testing a new setup, especially ANTHROPIC_BASE_URL, ANTHROPIC_API_KEY, and ANTHROPIC_AUTH_TOKEN.

Recommended Setup

Claude Models
GPT or Gemini Models

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://api.pipellm.ai",
    "ANTHROPIC_AUTH_TOKEN": "your-pipellm-api-key",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "claude-sonnet-4-6",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "claude-haiku-4-5-latest"
  }
}

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://api.pipellm.ai/anthropic",
    "ANTHROPIC_AUTH_TOKEN": "your-pipellm-api-key",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "gpt-4o",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "gpt-4o-mini"
  }
}

You can swap the model IDs for other PipeLLM models such as gemini-2.5-pro or gemini-2.5-flash.

If you want to keep a checked-in project config instead of editing your global settings, keep the same env block in the settings file that Claude Code reads for your environment.

Notes

Claude Code expects Anthropic Messages-compatible endpoints such as /v1/messages.
PipeLLM’s native route is the cleanest choice for Claude models.
PipeLLM’s /anthropic converter route is the safest way to keep Claude Code’s protocol while switching to OpenAI or Gemini models.
