FreeLLMAPI Aggregates Free AI Tiers Into a Single OpenAI-Compatible Endpoint

Overview of FreeLLMAPI

FreeLLMAPI is an open-source, local-first project designed for personal experimentation. It aggregates free tiers from dozens of AI providers behind a single OpenAI-compatible `/v1` endpoint. By combining multiple services, the project reports an estimated working inference capacity of roughly 7.4 billion tokens per month across 474 model families and 635 free endpoints.

Core Architecture and Features

• Unified Endpoint: Instead of managing 34 different SDKs and rate limits, developers point standard OpenAI-compatible clients to a local server.
• Smart Routing and Failover: The router assesses speed, capability, and reliability scores, automatically switching to another provider if a rate limit (`429`) or server error (`5xx`) occurs.
• Encrypted Key Storage: Provider API keys are stored encrypted using AES-256-GCM in a local SQLite database, exposing only a single unified bearer token to client applications.
• Self-Updating Catalog: A signed model catalog syncs automatically to track new models, quota changes, and compatibility updates without requiring manual software updates.

Practical Implications and Limitations

While the project simplifies prototyping across multiple free tiers, it is intended strictly for personal experimentation and learning, not production workloads. Stacking free tiers involves trade-offs such as variable latency, lack of service-level agreements (SLAs), and daily capacity caps that reset at UTC midnight.

Users must verify announcements, installation steps, and terms of service directly through the official GitHub repository and documentation index.
