Open Weight Model: Definition & Explanation
An open weight model is an AI model whose trained weights (parameters) are publicly released, enabling anyone to download and use it. Notable examples include Meta's Llama, Google's Gemma, Mistral's Mistral/Mixtral, and Stability AI's Stable Diffusion. While often confused with 'open source,' models that don't publicly release their training data or training code are more precisely called open weight (weights only). Organizations can run these models on their own servers, offering greater data privacy protection and customization flexibility. Quantization formats like GGUF are commonly used for local execution.
