Overview

Whale2API is a Go-based DeepSeek reverse proxy with an OpenAI-compatible Chat Completions interface. It supports the deepseek-flash model and an 896K context window, making it usable with clients that already speak the OpenAI API format.

The project brings the gateway and an account-pool management interface together, with SQLite-backed persistence and Docker deployment options.

Highlights

  • OpenAI-compatible /v1/chat/completions endpoint.
  • Support for image input with deepseek-flash.
  • A web interface for managing the account pool.
  • SQLite persistence and Docker Compose deployment.

Built on open source
