Their training data stays undisclosed, may ignore content owners' rights, and is heavily skewed toward English and a few high-resource languages. Apertus responds with a fully open suite of 8B and 70B models, both base and Instruct. Pretraining used 15T tokens drawn only… 2. **[Scaling Laws and Compute-Optimal Training Beyond Fixed Training Durations](https://md.research.elamur.ai/free/en/papers/hagele-2024-scaling-laws-compute-optimal-training/)** *(2024 · 26 citations)* The paper questions the habit of training large language models with a cosine learning rate schedule. This schedule performs best solely when its cycle is set to equal the full training duration. As a result, the model has to be trained from scratch for every token budget, which makes scaling laws studies expensive.… ## Co-authors here 8 co-authors with a page, the most papers together first. - [Alejandro Hernández-Cano](https://md.research.elamur.ai/free/en/authors/alejandro-hernandez-cano/) - [Angelika Romanou](https://md.research.elamur.ai/free/en/authors/angelika-romanou/) - [Bettina Messmer](https://md.research.elamur.ai/free/en/authors/bettina-messmer/) - [Elie Bakouch](https://md.research.elamur.ai/free/en/authors/elie-bakouch/) - [Leandro Von Werra](https://md.research.elamur.ai/free/en/authors/leandro-von-werra/) - [Loubna Ben Allal](https://md.research.elamur.ai/free/en/authors/loubna-ben-allal/) - [Martin Jaggi](https://md.research.elamur.ai/free/en/authors/martin-jaggi/) - [Mete Ismayilzada](https://md.research.elamur.ai/free/en/authors/mete-ismayilzada/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/): [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/) - [Conference on Neural Information Processing Systems (NeurIPS)](https://md.research.elamur.ai/free/en/venues/neural-information-processing-systems/): [NeurIPS 2024](https://md.research.elamur.ai/free/en/venues/neural-information-processing-systems/2024/) ## Cited by Papers of our library cite their works 75 times (of the 141,840 papers whose bibliographies we read); [10 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/alexander-hagele/cited-by/).
