Researchers open source Sky-T1, a ‘reasoning’ AI model that can be trained for less than $450


Researchers at UC Berkeley have open sourced Sky-T1, a 'reasoning' AI model that can be trained for less than $450.

On Friday, NovaSky, a team of researchers based out of UC Berkeley’s Sky Computing Lab, released Sky-T1-32B-Preview, a reasoning model that’s competitive with an earlier version of OpenAI’s o1 on a number of key benchmarks. “Remarkably, Sky-T1-32B-Preview was trained for less than $450,” the team wrote in a blog post, “demonstrating that it is possible to replicate high-level reasoning capabilities affordably and efficiently.” Palmyra X 004, a model recently released by AI startup Writer and trained almost entirely on synthetic data, reportedly cost just $700,000 to develop.
