**(a)** the tasks that the model is intended to perform and the type and nature of AI systems into which it can be integrated;

**(b)** the acceptable use policies applicable;

**(c)** the date of release and methods of distribution;

**(d)** how the model interacts, or can be used to interact, with hardware or software that is not part of the model itself, where applicable;

**(e)** the versions of relevant software related to the use of the general-purpose AI model, where applicable;

**(f)** the architecture and number of parameters;

**(g)** the modality (e.g. text, image) and format of inputs and outputs;

**(h)** the licence for the model.

**2.** A description of the elements of the model and of the process for its development, including:

**(a)** the technical means (e.g. instructions for use, infrastructure, tools) required for the general-purpose AI model to be integrated into AI systems;

**(b)** the modality (e.g. text, image, etc.) and format of the inputs and outputs and their maximum size (e.g. context window length, etc.);
