Apertus

After escaping European heat with 30+ hrs delay and missing luggage I am finally in San Diego attending @aclmeeting! 🇺🇸🌴#ACL2026 I will be presenting our work on the multilingual benchmark translation from @INSAITinstitute 🇺🇦🇧🇬 📍Poster Session E, July 6th 11.00-12.30 Also check out @apertusllm poster, presented by the greatest @agromanou, to know more about the biggest fully open multilingual models 🇨🇭 📍Poster Session F, July 7th 9.00-10.30

Three new model weights: 0.5B, 1.5B, 4B are available using new quantization and distillation techniques. Download #Apertus 1.1, read the ICML workshop report, try a new demo - all just a tap away in our latest blog post: apertus-ai.org/articles/2026-…

@Ivrolan @Laz4rz @ETH_en @EPFL_en @cscsch @elvisnavah ?

@Laz4rz @ETH_en @EPFL_en @cscsch this is great news! do you know any project that uses apertus in robotics?

Apertus is now also present on X! The @ETH_en, @EPFL_en and @cscsch co-initiative is one of the only ones in Europe that seem to have a real shot at building a lab culture similar to one from a proper frontier lab. There isn’t too much pressure on project-based results, instead there is a vision on compounding the learnings inside the team, iteratively producing better models and also sharing with the academic community

Apertus Mini is now running entirely in your browser 🇨🇭 80+ tps for the 1.5B, 60+ tps for the 4B (on my M3). Fully client-side via Transformers.js + ONNX + WebGPU.

Congratulations to each of the 102 authors of the #Apertus v1 report, officially published today ahead of the presentation at #ACL2026NLP in July. Follow @aclmeeting for updates aclanthology.org/2026.acl-long.…
