**Pleias-3b-Preview** is an early preview of a 3 billion parameters base model trained by Pleias on Common Corpus. |
|
|
|
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 OCR correction. Given the small size of the model we do not recommend fine-tuning methods based on LORA. |
|
|
|
## Training |
|
Pleias-3b-Preview was fully pretrained at Jean Zay on 64 h100s for 46 hours with Nanotron, the pretraining library from HuggingFace. We provide the complete settings as a yaml file as part of our release. |
|
|
|
Training schedule includes 518,000 steps (batch size 1,024) on a filtered and enhanced version of Common Corpus (1,086,324,736,000 tokens). |
|
|
|
## Update |
|
Pleias-3b-Preview is currently released as an early preview. |
|
|
|
The model will undergo several more round of post-training to enhance reasoning capacities and fine-tunability as well as in anticipation of a generalist instruct version. |
