New Pleias 1.0 LLMs trained exclusively on openly licensed data (via) I wrote about the Common Corpus public domain dataset back in March. Now Pleias, the team behind Common Corpus, have released the first family of models that are:

[...] trained exclusively on open data, meaning data that are either non-copyrighted or are published under a permissible license.

There's a lot to absorb here. The Pleias 1.0 family comes in three base model sizes: 350M, 1.2B and 3B. They've also released two models specialized for multi-lingual RAG: Pleias-Pico (350M) and Pleias-Nano (1.2B).

Here's an official GGUF for Pleias-Pico.

I'm looking forward to seeing benchmarks from other sources, but Pleias ran their own custom multilingual RAG benchmark which had their Pleias-nano-1.2B-RAG model come in between Llama-3.2-Instruct-3B and Llama-3.2-Instruct-8B.

The 350M and 3B models were trained on the French government's Jean Zay supercomputer. Pleias are proud of their CO2 footprint for training the models - 0.5, 4 and 16 tCO2eq for the three models respectively, which they compare to Llama 3.2,s reported figure of 133 tCO2eq.

How clean is the training data from a licensing perspective? I'm confident people will find issues there - truly 100% public domain data remains a rare commodity. So far I've seen questions raised about the GitHub source code data (most open source licenses have attribution requirements) and Wikipedia (CC BY-SA, another attribution license). Plus this from the announcement:

To supplement our corpus, we have generated 30B+ words synthetically with models allowing for outputs reuse.

If those models were themselves trained on unlicensed data this could be seen as a form of copyright laundering.

Releasing the largest multilingual open pretraining dataset (via) Common Corpus is a new "open and permissible licensed text dataset, comprising over 2 trillion tokens (2,003,039,184,047 tokens)" released by French AI Lab PleIAs.

This appears to be the largest available corpus of openly licensed training data:

• 926,541,096,243 tokens of public domain books, newspapers, and Wikisource content
• 387,965,738,992 tokens of government financial and legal documents
• 334,658,896,533 tokens of open source code from GitHub
• 221,798,136,564 tokens of academic content from open science repositories
• 132,075,315,715 tokens from Wikipedia, YouTube Commons, StackExchange and other permissively licensed web sources

It's majority English but has significant portions in French and German, and some representation for Latin, Dutch, Italian, Polish, Greek and Portuguese.

I can't wait to try some LLMs trained exclusively on this data. Maybe we will finally get a GPT-4 class model that isn't trained on unlicensed copyrighted data.

Releasing Common Corpus: the largest public domain dataset for training LLMs (via) Released today. 500 billion words from "a wide diversity of cultural heritage initiatives". 180 billion words of English, 110 billion of French, 30 billion of German, then Dutch, Spanish and Italian.

Includes quite a lot of US public domain data - 21 million digitized out-of-copyright newspapers (or do they mean newspaper articles?)

This is only an initial part of what we have collected so far, in part due to the lengthy process of copyright duration verification. In the following weeks and months, we’ll continue to publish many additional datasets also coming from other open sources, such as open data or open science.

Coordinated by French AI startup Pleias and supported by the French Ministry of Culture, among others.

I can't wait to try a model that's been trained on this.
