French AI company Mistral releases Mistral Large 4,API is now available for preview, and the model weights are planned for public release in October 27. Its performance data comes mainly from self-testing, and cross-model comparisons still have differences in evaluation criteria.
Reflection announces its first open-weight model, Beam, using a 501000000000-parameter MoE architecture. It is currently still in the safety-testing phase, with full weights planned for release later this month.
Germany AI company Aleph Alpha has released and open-sourced the English-German bilingual MoE model Kolibri; its weights have been uploaded to Hugging Face under the Apache 2.0 license. The material states that it supports tool calling, adjustable reasoning modes, and context of up to approximately 1000000 token s.
