AI models grow more powerful and more demanding

Meta’s Muse Spark Open demonstrates both the capabilities and extraordinary hardware demands of the latest open-weight AI models. The multimodal system has 816 billion parameters and a 1-million-token context window. Running it locally requires approximately 1TB of unified memory and a compatible Mac configuration estimated to cost more than $40,000.

Google, meanwhile, has opened Gemini 4 Argon to paying Gemini and API customers. The...

'Remarkably close to the minimum permitted by physics': this superconducting memory bit runs at an estimated 5x the limit, but at -269°C the fridge shrinks its claimed million-fold edge over today’s chips considerably

* Hebrew University physicists estimate a single superconducting vortex can act as a memory bit at about five times Landauer's limit, at 4.2 kelvin * The fivefold figure is a simulation-based estimate anchored to continuous-drive measurements, not a measured erasure, however * The release's million-fold edge over conventional
