LLM-API-Key-Proxy: Universal LLM Gateway: One API, Every LLM (github.com)

The launch of the LLM-API-Key-Proxy introduces a universal gateway that simplifies access to multiple Large Language Model (LLM) providers through a single API endpoint. This self-hosted proxy is OpenAI-compatible and caters to applications that support custom OpenAI URLs, allowing users to switch between different LLMs—such as OpenAI, Anthropic, and Gemini—without modifying existing code. Key features include an intelligent resilience library for API key management, automated key rotation, error failover, and support for custom providers like Antigravity and Qwen Code. This development is significant for the AI/ML community as it streamlines the integration of diverse LLMs, promoting flexibility and efficiency in application development. The proxy's capabilities, such as automatic cooldowns and rate limit handling, ensure reliable service during high-demand situations. Additionally, it aids in managing API credentials securely and efficiently, making it an attractive solution for developers looking to leverage various LLM technologies while minimizing maintenance overhead.
