Plexus: Unified API gateway for multiple AI providers

Plexus emerges as a sophisticated API gateway specifically designed for AI model interactions, solving critical infrastructure challenges faced by developers working with multiple AI providers. By providing a single, consistent endpoint, Plexus abstracts away the complexities of different provider protocols, enabling seamless model switching and advanced routing strategies.

The platform's most compelling features include intelligent provider selection mechanisms like cost-based, performance-based, and latency-optimized routing. Its vision fallthrough capability is particularly innovative, allowing developers to use vision-capable model aliases with backends that don't natively support image inputs by automatically generating text descriptions. The built-in OAuth provider support and per-request tracking further distinguish Plexus from traditional API management tools.

From a technical perspective, Plexus supports protocol translation between OpenAI, Anthropic, Google Gemini, and other OpenAI-compatible providers. Its database-driven configuration, AES-256-GCM encryption, and comprehensive quota management system make it a robust solution for teams requiring flexible, secure AI infrastructure. The project demonstrates a thoughtful approach to the evolving challenges of multi-provider AI integration.
