What is LM Studio?

Since no data is sent externally, it provides complete privacy protection for individuals and businesses handling sensitive information. LM Studio features an OpenAI-compatible local API server, allowing existing ChatGPT-integrated applications to work seamlessly with local models. It supports GGUF quantized models, enabling even 70B parameter models to run on PCs with just 16GB of RAM. With multi-GPU support and Apple Silicon optimization, it delivers fast inference even in local environments.
