Open weights
By HubAI editorial team · Source checked: 24 October 2026What does it mean?
Model weights made available under stated terms. Availability of weights does not by itself mean the training data, training code or all commercial rights are open.
Picture this
A company downloads model weights to run on its own hardware, then checks the licence to see whether its intended business use and redistribution are allowed.
Where you’ll come across it
Local deployment, research and greater control over hosting. You still need computing resources, operational support and a review of licence conditions.
What it doesn’t mean
Do not treat open weights and open source as interchangeable labels. Inspect the actual licence, restrictions and supporting materials rather than relying on a marketing badge.
Find the point where someone must check
A short exercise · use fictional or non-sensitive material.
- Choose a harmless draft, such as an invitation with fictional names and dates.
- List the claims and actions separately: what must be true, and what would happen if you approved it?
- Check the claims against your notes. Keep sending, publishing and account changes behind a real approval step.
Can a person see the evidence and stop the action before it happens?
