Tesla has updated its Optimus humanoid robot with a new hand design that features 22 degrees of freedom, plus three more in the forearm. The company added a soft protective layer to the fingers and palm that preserves the hand's tactile sensing capabilities while enabling it to handle delicate objects. All of the hand's actuators now sit in the forearm. Tesla says it plans to finish integrating the tactile sensors, implementing tendon-based fine control, and reducing the forearm's weight by the end of this year. Going forward, Tesla intends to equip all new Optimus robots with this enhanced hand design.

The 7-billion-parameter language model Teuken-7B is now available on Hugging Face, offering support for all 24 official European Union languages. The model comes from the EU's OpenGPT-X research project and is available as open-source. Unlike most AI language models that focus mainly on English, Teuken-7B was built from scratch with about half of its training data coming from non-English European languages. The developers say the model performs reliably across all languages it was trained on. The project team also created the European LLM Leaderboard that measures how well LLM's work across European languages, moving beyond the English-only testing that was standard before.
