A wave of open clones chases Jev’s viral decision model, Anthropic says Claude now does a quarter of its own R&D, and researchers reveal how they broke into OpenAI’s internal monorepo. Meanwhile Washington debates AI safety after California orders a kill-switch review, Riyadh reports smoke near its airport, and older Australians say they’d happily watch house prices fall for their kids’ sake.
🤖 Models and Launches
Open-source Jev clones flood out within days of the closed launch — Six reproductions of the viral non-generative decision model appeared in 48 hours, from a 421M-param ModernBERT variant to a 0.5B MacBook-runnable ‘Kev’, though the category still lacks a standard benchmark.
