Announcement of a major new frontier-scale foundation model with significant efficiency improvements over existing models.
Microsoft has pre-trained MAI-Base-2, a new MoE foundation model with 2.8 trillion total parameters that achieves 4-12x better pre- efficiency than DeepSeek-V4-Pro-Base.
DeepSeek released V4.1 Flash 1017, a sparse MoE model with CED architecture offering cost-efficient performance for coding agents and long-context tasks.
Meta releases Muse Spark Open, an 816B-parameter multimodal MoE model with open weights that scores highest among US open-weights models on Artificial Analysis' Intelligence Index.
Reflection releases Beam, a 501B parameter open-source MoE model optimized for coding and agentic use cases with 1M token context and Apache 2.0 license.
Elorian released Glimpse, an AI model that reasons with images by repeatedly zooming and cropping during analysis rather than converting to tokens once.
Perplexity AI has released pplx-decider-flash-v1.2 model weights on Hugging Face, supporting multimodal inputs and tool calling functionality.
