Pleias 3b Preview EU AI Act Compliance Profile

Pleias-3b-Preview is an early preview of a 3 billion parameters base model trained by Pleias on Common Corpus. Pleias-3b-Preview was pretrained at Jean Zay (compute grant n°GC011015451) with support from Etalab

Like all the base and specialized models from Pleias, Pleias-3b-Preview has only been trained on open data out of copyright (public domain) or under a permissible license.

Description

Pleias-3b-Preview is a transformer base model, entirely pretrained from scratch, using an architecture similar to Llama/GPT-Neox for easier deployment/inference.

It includes the following features, that would apply to any responsibly trained variant:

• Only trained on open data under a permissible license and in compliance with the European AI Act. By design, all Pleias model are unable to output copyrighted content.
• Extensive multilingual support for main European languages.
• A new tokenizer designed for enhanced document processing tasks and better multilingual support.
• Extremely low level of toxicity and problematic content.

Fully supported languages include English, French, Spanish, German, Italian, Dutch, Latin and Portuguese.

Recommended use

As a base model, Pleias-3b-Preview is only able to run continuation prompts.

Text generation is currently able to support a range of creative writing tasks in multiple European languages. For more consistent results we recommend using a low or null temperature with a slight repetition penalty (1.1-1.2).

Pleias-3b-Preview has been successfully adapted for continuous pretraining and full-fine-tuning on document processing tasks such as RAG, translation or O
