This week: American labs racing to build open-weight AI models before China’s Kimi K3 locks in its lead, the policy fight over banning those Chinese models, and how a toilet maker became a critical semiconductor supplier.

1. American Open-Source Labs Think They Can Beat China’s Best AI Startups

US open-source labs Poolside, Thinking Machines and Reflection AI challenge dominant Chinese models like Moonshot’s Kimi K3
Poolside, Thinking Machines, and Reflection AI are racing to build American open-weight models, since Anthropic and OpenAI have little reason to release open weights themselves.

Poolside’s new Laguna claims to lead the West’s open field, though it’s a fraction of the size of Moonshot’s 2.8 trillion parameter Kimi K3.Thinking Machines just shipped its first open model, Inkling, betting on flexibility over benchmark scores.

2. Kimi K3: The open-weights escalation

Moonshot AI releases Kimi K3 2.8T parameter MoE model, weights to be released July 27 as China escalates open-weights AI strategy
Kimi K3 narrows the gap between Chinese and American models to a matter of months, and Moonshot pending releasing its weights on July 27. China ships models open because that’s what gets fast adoption and feedback.

Some American Labs are lobbying to ban Chinese open-weight models on safety grounds, but that argument doesn’t hold. It would leave US models guardrailed on cybersecurity while foreign actors keep using capable Chinese models to probe American defenses anyway and it would cut off businesses that want to build domain-specific agents on open weights.

TOTO From Toilets to E-Chucks
TOTO built a century of expertise in advanced ceramics making toilets and sinks, then turned it into a critical supply position in semiconductors. Its Advanced Ceramics division is now the world’s leading maker of electrostatic chucks, the components that hold silicon wafers steady during etching.

That dominance matters most in 3D NAND, where TOTO’s chucks handle the cryogenic conditions needed to etch high-aspect-ratio memory holes.
