The permanent baseline goes up 25 percent, but the 50 percent temporary boost in force today expires on September 14. The gap is the cut.
All ten alignment benchmarks improved without degrading overall performance. The paper does not shy away from the comparison with human researchers.
The complaint targets how the data was obtained, not just how it was used. The company already paid $1.5 billion over the same weak spot.
A research preview aimed at letting AI agents drive robot arms and sensors without writing a bespoke driver for each one.
A federal judge called the designation unlawful retaliation. The dispute began over the company's limits on autonomous weapons and mass surveillance.
