Pleias is definitely the most promising.
I haven't seen a model trained on that corpus since late 2024: https://simonwillison.net/2024/Dec/5/pleias-llms/ - I may have missed something though.

Common Corpus is commonly used now in pretraining, including by close labs, but rarely as the only source (which would be the actual ethical commitment).
Like most people training efficient models we move toward synthetic pretraining, but still maintaining our committment for data research and releasability. Lead current project is SYNTH, for now based on Wikipedia but we'll generalize with seeds from Common Corpus.
