Startup founders urge Trump not to shut off Chinese open weight AI
About 200 Silicon Valley startups have formed a new coalition called the 'Little Tech Association' — including Proton, Replit, and Y Combinator — and sent a letter urging the Trump administration not to cut off access to Chinese open-weight AI models. Particle founder Suhail Doshi warned that such a ban would cause "hundreds of companies to die immediately." The petition comes just after Moonshot AI released its powerful Kimi K3 model, adding urgency amid reports that the administration is weighing a ban on Chinese AI models.

Fractal by Plasma AI
Plasma AI has open-sourced 'Fractal,' a tool for building hierarchical agent loops. Each node works iteratively toward a goal in its own git worktree, spinning off separable subtasks into child nodes — so instead of a fixed plan, the tree grows to match the size of the problem. Hard caps on iteration count, depth, number of children, cost, and time bound every loop. In a test run against its own repository, a 187-node tree found 135 issues and fixed 55 of them test-first.
