Tesla unveils the second generation of its Optimus robot. As well as cars, the company is also building a human-like robot that one day might be able to perform many tasks. In a short video, Tesla shows the new Optimus Gen 2, whose design is now closer to the original vision. The robot now has Tesla-developed actuators and sensors, faster and more capable hands with tactile sensors, a 30% faster walking speed, lower overall weight, and an articulated neck.
French startup Mistral AI has released its new language model Mixtral 8x7B via a torrent link. Mixtral is a mixture-of-experts model, following an architecture that OpenAI is rumored to be using for GPT-4, but on a much larger scale.
There are no benchmarks, blog posts, or articles about the model yet, but Mistral-7B — the first version of Mistral AI — generally performed very well and was quickly adopted by the open-source community. Mistral is thought to have used the MegaBlocks MoE library for training. The Paris-based company was recently valued at nearly $2 billion.
