Meta releases Muse Spark Open weights, built with Apple to run on Macs
Meta released Muse Spark Open, an 816B-parameter open-weight model with 42B active parameters that handles text, images, video and audio with up to one million tokens of context. Meta calls it the most capable US open-weight model to date, and Meta says two M5 Ultra Mac Studios running Apple’s MLX framework can run the model locally, and the license allows limited commercial use. The Decoder says it performs roughly on par with the strongest Chinese open-weight models on benchmarks. In an a16z episode this week, Nathan Lambert discussed whether open models can keep up with OpenAI and Anthropic.

Tesla unveils thruster-equipped Roadster that briefly flies; production in 2028
Tesla showed its next-generation Roadster at a SpaceX test site near Waco, Texas, almost a decade after it began taking deposits. Using cold-gas thrusters, the car drove up an inverted ramp, hovered, and leapt over a Cybercab, Cybertruck, Semi, Model Y and Model 3; Tesla timed 0-60 mph at about one second. Elon Musk said production starts in 2028 but gave no price, and said the car may not move the needle much on revenue. Buyers in the US, Canada and China can reserve one with a $50,000 deposit.

Goodfire researcher argues neural networks are far more interpretable than thought
Nick Cammarata of interpretability startup Goodfire published a long research essay arguing that polysemanticity in early models was caused by ordinary, mostly fixable issues rather than superposition. He says most neurons can now be understood in models up to trillions of parameters, and that the outlook for mechanistic interpretability is far better than feared. He presents it as a working hypothesis with preliminary estimates.
