European Open Source AI Index

Parameter descriptions:

Base Model Data

Are datasources for training the base model comprehensively documented and freely made available? In case a distinction between base (foundation) and end (user) model is not applicable, this mirrors the end model data entries.

End User Model Data

Are datasources for training the model that the enduser interacts with comprehensively documented and freely made available?

Base Model Weights

Are the weights of the base models made freely available? In case a distinction between base (foundation) and end (user) model is not applicable, this mirrors the end model data entries.

End User Model Weights

Are the weights of the model that the enduser interacts with made freely available?

Training Code

Is the source code of datasource processing, model training and tuining comprehensively and freely made available?

Code Documentation

Is the source code of datasource processing, model training and tuning comprehensively documented?

Hardware Architecture

Is the hardware architecture used for datasource processing and model training comprehensively documented?

Preprint

Are archived preprint(s) are available that detail all major parts of the system including datasource processing, model training and tuning steps?

Paper

Are peer-reviewed scientific publications available that detail all major parts of the system including datasource processing, model training and tuning steps?

Modelcard

Is a model card in standardized format available that provides comprehensive insight on model architecture, training, fine-tuning, and evaluation are available?

Datasheet

Is a datasheet as defined in "Datasheets for Datasets" (Gebru et al. 2021) available?

Package

Is a packaged release of the model available on a software repository (e.g. a Python Package Index, Homebrew)?

API and Meta Prompts

Is an API available that provides unrestricted access to the model (other than security and CDN restrictions)? If applicable, this entry also collects information on the use and availability of meta prompts.

Licenses

Is the project fully covered by Open Source Initiative (OSI)-approved licenses, including all data sources and training pipeline code?
