U.S. payrolls rose 29,000 in September as earlier estimates were revised down by 60,000

The Bureau of Labor Statistics released its September employment estimates on October 2. Nonfarm payrolls rose by 29,000 jobs, and unemployment was 4.2%. BLS said both measures changed little.

These national labor-market estimates do not show job losses caused by AI. September's payroll estimate is preliminary and may change. Combining it with New York job postings would not produce a count of workers displaced by AI.

Applied Digital says another 75 MW at Polaris Forge 1 is ready for service

Applied Digital announced on October 2 that three more data halls at Polaris Forge 1 were ready for service. Each hall adds 25 megawatts of capacity for computing equipment, for a total of 75 megawatts in Building 2. This critical IT load measures computing capacity, not electricity generated at the site.

The capacity and completion figures come from the company. The release does not independently measure customer usage, occupied server capacity or revenue. Ready-for-service status does not mean customers are using every megawatt.

Nvidia announces a $4,999 DGX Spark with 64 GB, due October 23

Nvidia announced a DGX Spark configuration with 64 gigabytes of unified memory on October 2. The company says it will be available exclusively through manufacturer partners on October 23, starting at $4,999.

October 2 was the announcement date, not the availability date. Nvidia's model-size limits do not independently prove how every model will perform. The company reported a speedup of up to 1.7 times in a specific Qwen 3.8 27B test. It ran that test on two 64-gigabyte units.

Researchers use AI to adjust a room-temperature process for making solar-cell crystals

A Nature Communications paper published October 2 describes a room-temperature method for making perovskite nanocrystals. These tiny crystals are used in solar-cell materials. The researchers paired automated synthesis with machine learning. Their system changes how much of each chemical enters the process.

The cost figures estimate the price of making nanocrystal material, not solar panels or electricity. Chemistry, solvents, continuous flow and labor assumptions all shape the comparison. Machine learning alone cannot account for the estimated saving. The accepted manuscript may still receive final edits, and it does not show commercial factory production.

A New York report finds fewer junior postings as employers ask for more AI skills. The data does not establish AI-caused job losses.
