What's New

Claude Code Compatibility

  • Strip cch billing headers: automatically removes cch request identifiers from headers to prevent billing conflicts when using Claude Code with non-Anthropic providers
  • CLAUDE_CODE_ATTRIBUTION_HEADER toggle: new control in the Claude Code launcher to enable or disable the CLAUDE_CODE_ATTRIBUTION_HEADER environment variable

OpenAI Responses API Support

  • Added proxy support for the OpenAI Responses API endpoint (/v1/responses)
  • Responses API format is handled alongside Chat Completions for seamless integration

Bug Fixes & Improvements

  • Fixed URL building: proxy now correctly constructs upstream URLs for providers with non-standard paths (e.g., /v3)
  • Fixed streaming error responses: upstream errors during SSE streaming are now returned in proper SSE format with correct data: prefix and newline termination
  • Build warnings cleaned up: removed unused variable initialization

  • feat: add OpenAI Responses API (/v1/responses) proxy support
  • feat: add RectifierModels for Claude Code billing header handling
  • feat: strip cch billing headers in HTTPServer
  • feat: add CLAUDE_CODE_ATTRIBUTION_HEADER toggle in Claude Code launcher
