Today starts with Meta's new model. Then we cover compute contracts, job cuts, a court fight, school rules, government pressure, and RNA delivery.

Meta cuts the cost of frontier A I tasks. Meta released Muse Spark 1.3 on Wednesday in Muse Code and the Meta Model API. Meta says the model handles longer agent workflows and follows complex instructions more reliably. Meta engineers also measured about 20 percent fewer tool calls and 25 percent fewer tokens than Muse Spark 1.2. Artificial Analysis gave the available xhigh version a 61 on its Intelligence Index. That put it four points above Muse Spark 1.2 and tied it with several frontier systems. At Meta's unchanged API price, Artificial Analysis measured a $0.55 cost per index task. No other model scoring 59 or higher cost less. The limited-preview max version scored 62, one point higher, but Meta has not published its price. The pressure: Meta made the usability and safety claims. Artificial Analysis measured benchmark performance and task cost independently. A benchmark still does not prove that a model will hold up inside a specific business workflow. What to watch: Watch for signs that the max version keeps its score after a wider release. Watch what Meta charges for it, and whether Meta ships the promised open-weights release. Real agent completion rates matter too. Meta reports fewer tool calls and tokens. Product teams still need to test that efficiency on their own work.

Nscale tells investors it has $103 billion under contract. Reuters reported, citing The Information's account, that Nscale showed investors a possible 2027 IPO pitch. The British AI infrastructure company forecast about $2 billion in revenue next year and $15 billion in 2029. The pitch says Nscale has $103 billion in contracted revenue. It named customers including Microsoft, OpenAI, and Anthropic. That is a long-term contract claim, not collected sales. Nscale did not respond to Reuters's request for comment. One publication described a private investor pitch. The figures remain a company forecast, not independently verified revenue. The next tests are audited accounts, contract lengths, and the capital Nscale must raise before an IPO. Huge compute commitments matter only if Nscale can pay for and build the data centers behind them.

Uber plans to cut 3,300 jobs as robotaxi rivals close in. Bloomberg reported that Uber plans to eliminate about 3,300 corporate jobs. Reuters and The Guardian cited that report. The cuts equal roughly 10 percent of Uber's global workforce. An internal memo called the move a reset to remove layers and speed decisions. The cuts are Uber's largest since 2023. Uber is also spending to compete in autonomous driving and delivery. Uber did not immediately comment to Reuters. The memo tied the cuts to management structure and speed, not directly to AI. Robotaxi competition is business context here, not Uber's stated reason for the layoffs. The next test is which teams lose staff, and whether Uber shifts more spending toward autonomous vehicle partnerships. The sharper question is whether fewer management layers help Uber move faster, or leave it with less capacity.

Justice Department backs OpenAI on fair use. The Justice Department urged a New York federal judge to accept OpenAI's fair-use argument. OpenAI argues that training models on copyrighted news articles is fair use. In a September 1 statement of interest, the department addressed the publishers' consolidated case. The department said a ruling against OpenAI would raise licensing costs and favor the largest technology companies. It also said that ruling would weaken the United States against foreign competitors. The filing supports OpenAI's legal theory. It does not decide the case. The New York Times said the administration is siding with large AI companies at creators' expense. The Times argued that model developers should pay for protected work. Judge Sidney Stein still has to apply the four-part fair-use test to the facts before him. Next, watch whether Judge Sidney Stein treats the government's innovation and national-security arguments as part of fair use. A ruling on model training would reach beyond this lawsuit. Publishers and AI companies are still negotiating licenses while the legal baseline remains unsettled.

New York City bars younger students from generative A I. New York City barred public school students below high school from using generative A I during the school day. High-school students can use only tools their schools provide. The city also capped device-based instruction at one hour a day for kindergarten through eighth grade. It extended its smartphone ban across elementary and middle schools. Officials said the rules are meant to protect independent thinking and human connection. The policy draws a clear age line, but a huge school system still has to enforce it. Teachers need useful non-A I software and enforcement rules. They also need to separate banned generation from search, accessibility tools, and tutoring tools. Watch the implementation guidance and the high-school tool list. New York still has to show whether it can teach these systems while sharply limiting their classroom use.

Anthropic and Commerce restart talks after Pentagon dispute. Commerce Secretary Howard Lutnick said the Trump administration is in active talks with Anthropic. He said the administration wants the company back on the government's right side after a public dispute over military uses of its models. Lutnick said Anthropic has worked closely with officials on cyber tools. He contrasted Anthropic with OpenAI, which he said gave the government what it asked for. The comments suggest a thaw, not a settlement. Lutnick's remarks and the reports do not show what Anthropic has agreed to change. The core dispute involved limits on autonomous weapons and domestic surveillance. That makes the missing contract language more important than the warmer tone. The next evidence would be a revised federal contract, changes to Anthropic's usage rules, or formal removal of restrictions tied to the Pentagon dispute. A deal would show how much leverage the government has over model safety policies.

A I-designed proteins delivered RNA in animal tests. Researchers built more than 100 synthetic RNA carriers from natural functional domains and protein assemblies designed by generative models. Their best design, STV-C8, transferred RNA more efficiently than the virus-like particles and lipid nanoparticles tested in cell culture. The team tracked delivery in mice. The team also used the carrier to remove a disease-related section of the dystrophin gene in pig muscle cells. This is early laboratory and animal work, not a human treatment. After intravenous dosing, the carrier delivered RNA mainly to mouse lungs. The team still has to improve targeting and study how the carrier moves through the body. Watch replication, immune-response testing, and control over which tissues receive the cargo. The result gives researchers another way to build delivery vehicles. Clinical value depends on precise targeting and repeatable safety.
