Open weights

What it measures

Open weights mean you can download the model and run it on your own infrastructure. Closed weights mean access is through an API only.

When it matters

It matters for privacy, data protection rules, cost at scale and customization. Always check the license: open weights can still carry commercial limits. If the data cannot leave your network, this column comes before the score.

How to read it

If the data cannot leave your network, filter by open weights and check the license in the official repository. Open weights can still carry commercial limits.
