Quasar 1.2 358B

by Multiverse Computing

Released 35 days after Quasar 438B · Announcement · All Multiverse Computing releases

Quasar 1.2 358B is a 358-billion-parameter reasoning model from Multiverse Computing, compressed from Z.ai's GLM 5.2 with the company's CompactifAI method. It follows Quasar 438B as the newer, smaller release. It supports tool calling and reasoning at high and max effort (always on), over a 202K-token context. It suits coding, agents and long-document work where a smaller footprint than the original GLM model matters.
