Free, open-source alternative to OpenAI API running locally

⭐ 49k+ stars 📜 MIT 🏷️ ai-tools

Overview

Free, open-source alternative to OpenAI API running locally

✓ Drop-in local replacement for the OpenAI API — zero code changes needed to switch from cloud to local
✓ Compatible with 40+ model backends: GGUF (llama.cpp), GPTQ, Whisper, Stable Diffusion, and more
✓ Single API endpoint handles text, embedding, transcription, and image generation uniformly

✗ LLM throughput is ~30-50% lower than native vLLM for the same NVIDIA GPU hardware
✗ Configuration requires YAML model definition files — more setup overhead than Ollama
✗ Multi-model serving increases RAM requirements significantly (each loaded model stays in memory)
