Open Weight Models

Modelli Open Weight

Open weight models are AI models whose trained parameters are publicly downloadable: anyone can run them on their own servers, study them, fine-tune them. Examples: Meta's Llama, Mistral, Google's Gemma, DeepSeek. They contrast with closed models (GPT, Claude, Gemini) accessible only via API.

Definition

"Open weight" is not strictly "open source": training data and code often remain private. For companies the advantages are control and privacy, the model runs in your infrastructure and data never leaves.
