Washington set a floor price for imported silicon, a genome model designed 285 viruses and 16 of them worked, and Datadog's largest customer told it to expect less.
Good Morning! Thursday drew two lines under the AI economy. Trump signed a proclamation that does not just tax imported polysilicon but sets a minimum price for it, semiconductor grade included, and Musk answered the chip shortage by announcing a fab of his own. In the labs, Science published a genome model's viral designs while Anthropic reopened most biology questions on its most capable model. And two of the day's quieter numbers point the same way: China's open weight labs want a cut of your revenue, and Datadog's biggest AI customer is cutting back.
Policy
A floor price for silicon, and a tariff for anyone who comes in under it
Trump's Thursday proclamation tries something US trade policy has not: it sets minimum import prices, $21 a kilogram for polysilicon, $100 for ingots and wafers, $0.22 a watt for solar cells and $0.38 for modules. An importer must document a first arm's length sale at or above the floor or pay the shortfall as duty, and the entire floor if it documents nothing. A separate 15 percent tariff covers ingots and derivatives. Both bite December 4, and Commerce is told to stop anyone stockpiling first. Semiconductor grade silicon is in scope.
Research
A genome model designed hundreds of viruses from scratch, and 16 of them worked
Science published on Thursday the peer reviewed version of work from Arc Institute and Stanford that first appeared as a preprint last September. Using the genome language models Evo 1 and Evo 2, with the phage phiX174 as a template, the team generated whole viral genomes, synthesized 285 of them and got 16 that infected and killed E. coli; a cocktail of those phages also beat E. coli strains resistant to the natural virus. The models saw no human pathogen data. An accompanying Perspective argues that screening of synthetic DNA orders should be legally required rather than voluntary.
Frontier
Anthropic reopens most biology questions on Fable 5, but virology still routes elsewhere
Anthropic shipped Fable 5 with almost all biology blocked, reasoning that the model could hand a bad actor capabilities available nowhere else. It has now rewritten the classifier's constitution with outside expert input and retrained it, cutting biology-related fallbacks by about 85 percent overall; total fallbacks for any reason fell roughly 67 percent on Claude.ai and 55 percent on Cowork. The safeguard was never a refusal. Requests it still counts as dual use, virology and toxicology and molecular design among them, quietly fall back to Opus 5, an older and weaker model.
Compute
Musk is building his own chip fab because he does not expect anyone to sell him enough
SpaceX and Tesla will put $16.8 billion into a first phase of Terafab, a semiconductor plant in Grimes County, Texas, pitched as bridging the gap between global chip supply and the compute demand that is coming. More than 100 million square feet, at least 3,000 workers drawn from two counties, cooled with reservoir water rather than local groundwater. The chips are meant for inference in Optimus robots and Cybercabs and for SpaceX's orbital data centers. Intel has committed to contribute. None of it came up on SpaceX's earnings call this week.
Industry
China's open weight labs have found the part of open source you have to pay for
Alibaba plans to ask heavy commercial users of the next version of its open source Qwen model for a share of the revenue they make from it, Reuters reported late Thursday. The rate is undecided and the change is meant to land next week. Moonshot has already moved: its Kimi K3 license makes anyone reselling the model as a service on more than $20 million a year negotiate terms, and one source put the share as high as 30 percent. The weights stay free to download. What now costs money is running them at scale.
Industry
Datadog's largest customer is an AI company, and it just said it will use less
Datadog grew revenue 36 percent to $1.12 billion last quarter and the stock fell about 16 percent anyway. The reason surfaced on the call. The company's largest customer, which chief executive Olivier Pomel described as a leading AI company and which uses 17 Datadog products, renewed its contract but told Datadog it will cut users starting this quarter. Guidance now absorbs that, at $1.135 to $1.145 billion for the third quarter. Pomel says growth excluding that customer is unchanged. Datadog would not name it.

Beijing opens a cybersecurity review of Palo Alto Networks, the instrument it used on Micron
China's Cybersecurity Review Office said on Thursday that it has opened a review of the products Palo Alto Networks sells in the country, citing the National Security Law and the Cybersecurity Law and acting under the Measures for Cybersecurity Review. The notice names no product, alleges no particular vulnerability and sets out no penalty. It does not need to. This is the same instrument Beijing turned on Micron in 2023, and for a security vendor the review is itself the finding, since it is what buyers act on.
