Poids ouverts
In brief
The internal settings of an AI model, published so that others can run and adapt it on their own systems. You are no longer tied hand and foot to the provider, even if the licence isn’t always as permissive as that of open-source software.
▶ Precise definition
Public release of a model’s parameters (weights), enabling it to be run, fine-tuned and audited outside the creator’s organisation. This is distinct from strictly open source: the weights may be made available under a restrictive licence. This significantly reduces the risk of service disruption and vendor lock-in associated with a model accessible only via an API.
