Reverse engineered DeepSeek Chat into an OpenAI compatible API

A developer has created a local proxy that reverse-engineers the free DeepSeek consumer web chat to expose an OpenAI-compatible API endpoint at localhost:8000/v1. This tool allows existing OpenAI-compatible clients, such as Open WebUI and various SDKs, to interact with DeepSeek's V4 and R1 models without code changes or API keys.

• Exposes an OpenAI compatible /v1 endpoint with streaming responses and multi-turn conversation support.
• Logs into the user's DeepSeek account once and stores the session for reuse.
• Acts as a drop-in replacement for most OpenAI SDKs and clients.
• Designed for lightweight automations and hobby projects rather than production use.

This solution enables experimentation with DeepSeek models through familiar interfaces without incurring costs associated with the official paid API.
