Gemini Robotics 2 brings whole body intelligence to robots
Gemini Robotics 2 is a family of three models — a vision-language-action model for whole-body humanoid control, an embodied reasoning model (ER 2) that orchestrates tools and tracks task progress, and an on-device VLA that adapts to a new robot body in hours.
LFM2.5-Encoders for Fast Long-Context Inference on CPU
Two new encoder models, LFM2.5-Encoder-230M and 350M: they match larger encoders on GLUE, SuperGLUE and multilingual tasks, handle 8,192-token context, and run about 3.7x faster than ModernBERT-base on CPU at long context.
