What is Open Weights?
AI models whose trained parameters (weights) are publicly released for anyone to download, run, fine-tune, and build upon. Llama, Mistral, and DeepSeek are prominent open-weight families. Unlike proprietary APIs, open weights let you run models locally, customize them fully, and avoid vendor lock-in. For Web3 builders who value decentralization, open-weight models align with the ethos of user-owned infrastructure.

In plain words
"Think of it like a recipe published online — you can tweak it, remix it, or run it as-is on your own stove."
How it works
Key takeaways
-
Download and run on your own hardware
-
Full control over data privacy and customization
-
Open weights ≠ open source (training code may be closed)
Real-world example
Meta releases Llama weights: anyone can download them and run the model on their own hardware. No API dependency, no vendor lock-in. You control the model, the data, and the infrastructure entirely.
