The quick read
- Check the licence, model card, supported formats and any restrictions that apply to your use.
- Someone must manage storage, serving, updates, monitoring and access.
What access means
When model weights are available, a developer may be able to download and run the model using compatible software. The release may or may not include training data, full training code or permission for every intended use. ‘Open weights’ should therefore not be treated as a complete description of openness.
Read the release conditions
Check the licence, model card, supported formats and any restrictions that apply to your use. Record the exact version you download. A model’s ability to run locally does not establish that its outputs are accurate or that the original training process can be reproduced.
Plan the operating work
Someone must manage storage, serving, updates, monitoring and access. Test the model on a small set of real tasks before investing in a larger deployment. For a team, document who can change the model or configuration and how a previous working version can be restored. Open access can give useful control, but that control comes with practical responsibilities that a hosted product may otherwise absorb.
