DeepSeek said it has upgraded the R1 artificial intelligence model that helped propel the Chinese startup to global prominence at the start of this year.

The company completed what it described as a “minor trial upgrade” and is allowing users to start testing it, it said in an official WeChat group on Wednesday. Details of the upgrade weren’t provided and the company didn’t respond to an email seeking further comment.
