## Background and Problems

As large language models (LLMs) are increasingly used in enterprises, development teams face a common challenge: how to uniformly manage API access to multiple LLM providers. Different providers have different API formats, authentication methods, and billing models, which adds complexity to the operation and maintenance of production systems.

Supergate was born to address this—it sits in front of providers like OpenAI, Anthropic, Google, Cohere, and Mistral, providing teams with a stable, unified API and operational features required for production systems.

## Core Features

Supergate offers a range of enterprise-grade features to address common pain points in LLM integration:

## Unified API Interface

Regardless of the underlying provider, Supergate provides OpenAI-compatible endpoints. This means developers only need to learn one API format to flexibly switch or combine multiple LLM providers in the background.

## Multi-Tenant Architecture

Tenant isolation is achieved via PostgreSQL's Row-Level Security (RLS). Each tenant has independent API keys, Role-Based Access Control (RBAC), and usage data. This design supports both simple scenarios for startups and compliance requirements for large enterprises.

## Hybrid Key Management

Supports two key modes:
- **Gateway-hosted keys**: Simplifies onboarding, ideal for quick starts
- **Bring Your Own Key (BYOK)**: Meets enterprise compliance needs; tenants manage their own provider API keys

BYOK keys are stored encrypted using AES-256-GCM to ensure security.

## Semantic Caching

The cosine similarity cache based on pgvector is a key highlight of Supergate. When similar prompts are received, the system returns results directly from the cache without calling the underlying LLM. This brings two significant benefits:
- **Reduced latency**: Cache responses are almost instantaneous
- **Cost savings**: Avoids token costs from repeated calls
