Meta ships Muse Spark Open, optimised for Mac Studio with Apple's help

Meta released Muse Spark Open, an 816B-parameter open-weight mixture-of-experts model that handles text, images, video and audio with up to one million tokens of context. In an unusual collaboration, Meta and Apple co-optimised the model to run locally on two M5 Ultra Mac Studios via the MLX framework.

FLUX.3 Image Klein runs 4K generation on 8 GB GPUs

Black Forest Labs released FLUX 3 Image Klein, a 5.6B-parameter open-weights image model supporting native 4K generation and pixel-precise editing. It outperforms larger proprietary competitors in internal tests while running on consumer GPUs with just 8 GB of VRAM, making it accessible to solo developers and small teams.

GPT-6-Astra solves 49 of 50 physics research problems at $2.40 each

On the new TheoPhysEval benchmark of unpublished theoretical physics calculations, GPT-6-Astra matched or exceeded leading specialists. In several cases the agent's answers were correct where the experts' own reference solutions contained errors. Researchers note agents still lack the "taste" needed for genuine breakthroughs but say autonomous top-level AI research may arrive soon.

Anthropic gives METR employee-level access for independent safety audits

Anthropic has granted third-party evaluator METR employee-level access to its systems, letting the research group publish its own assessments of risks, incidents and practices. Anthropic has given up the right to block or edit those reports, setting a new bar for external AI safety oversight.

Productivity Commission holds firm on three-year AI copyright wait

The Productivity Commission has reiterated its position that the government should wait three years before considering any copyright carve-outs for AI training in Australia. The recommendation lands as a Joint Select Committee and both major parties negotiate a deal to satisfy rightsholders and AI companies alike.

Aged care algorithm triggers second independent review

The Albanese government has ordered another independent review of its algorithm-based Integrated Assessment Tool after ongoing concerns about accuracy and the level of human oversight. The review adds to two existing investigations into the tool, which determines the care packages elderly Australians receive.
