It later leapt over five other Tesla vehicles while twisting in the air. The car is scheduled to enter production in 2028. Tesla has yet to release a price tag. The Roadster can go from a stop to 60 miles an hour in about one second, and it has a top speed of over 230 miles an hour. Meta unveils Muse Spark Open, the new top US open weights model — and it runs on two paired Mac desktops (18 minute read) Muse Spark Open is an 816-billion-parameter open-weight model that can run on relatively affordable consumer hardware. Meta's benchmark tests used a pair of M5 Ultra Mac Studios with an unknown memory configuration. The model uses a mixture-of-experts design and activates 42 billion parameters for each token. It supports a context of up to 1 million tokens and accepts text, images, video, and audio, but only outputs text. 🚀 Science & Futuristic Technology Bringing the magic: Google breaks open a bottleneck in quantum computing (3 minute read) Google Quantum AI has demonstrated that 'magic state cultivation' works in practice on its Willow processor. Magic states help researchers create the operations they need for going beyond classical computing. Creating high-quality, error-corrected magic states is incredibly resource-heavy. This post details how Google Quantum AI created a magic state cultivation protocol that achieved a 40-fold reduction in errors. The breakthrough is a crucial step towards scaling up quantum computing to practical use. How to Train Your Robot (22 minute read) Training an AI model fundamentally requires lots and lots of examples of something being done correctly. Creating this data for training robots is expensive, and companies need a lot of data to train competent models. Large language models showed the benefits of scale when training models. Researchers are now working hard to gather enormous amounts of robot task training data in the hopes of seeing the same sort of trends with robotic capabilities. 💻 Programming, Design & Data Science New trend of building “internal vibe-coding apps” at tech companies (6 minute read) Tech companies are building internal vibe-coding tools for non-engineers. It's not that complicated, it gets higher adoption than vendor products, and it helps build out more AI intra expertise in-house. Building an internal vibe-coding tool is a tiny investment that can result in better, more custom tools than with vendor products, and companies don't have to wait on vendors to build what's needed. It's also a lot safer to expose internal data sources to internal tools. Using Artificial Intelligence to reverse engineer hardware (10 minute read) Developers are using Claude to debug hardware issues. AIs can read thousands of lines of USB capture, notice sequence repeats with one byte changing, make suggestions on what that byte means, and write the tests to confirm its suggestions. A human is still requi
