General-purpose AI models — the foundation models everyone builds on — sit under their own section of the EU AI Act. Articles 53 and 55 don't ask "are you a GPAI provider?" as a yes/no. They sort you into tiers based on what your model is and how it's released, and each tier carries different duties.
I built GpaiWatch because the tier you're in is a function of decisions you've already made, not a label you chose.
30-second takeaway
- GPAI isn't one obligation — it's a set of tiers keyed to model capability and release practice.
- The tier is determined by choices you've already made (scale, openness, downstream use).
- Mapping it early beats discovering your tier from a customer's questionnaire.
The tiers hide in your release plan
A team releasing a model often thinks "we're not one of the big labs, so this doesn't apply to us." But the Act keys obligations to specific triggers — capability thresholds, whether you're upstream or downstream, how the model is distributed. Those triggers are in your architecture and go-to-market, whether or not anyone has mapped them.
Picking your tier after the fact means retrofitting documentation and duties you could have planned for.
What the tool gives you
You describe the model and how you release it. It maps you to the Article 53 and 55 obligation tiers and lists what each requires. Not a legal opinion — a structured read that tells you which duties to plan for before you ship.
GpaiWatch runs in the browser, no account, no key. Describe the model and see your tier.
FAQ
What is GpaiWatch?
A mapper that takes a described general-purpose AI model and release practice and shows the Article 53/55 obligation tier it lands in. No account, no key.
Which tier means I'm done?
No tier means done. Each adds duties; the tool lists them so you can plan, not so you can stop.
Is this legal advice?
No. Decision-support for mapping, not a legal interpretation of your obligations.
Author's Process
This product was built with AI coding tools. The useful part was encoding the tier triggers as questions a release owner can answer.
