Z.ai has released GLM-Legal, a legal-domain agentic model built on its 320B-parameter GLM-5.3-Flash, scoring 19.2% all-pass on Harvey's LAB benchmark across 24 practice areas. Access is currently gated behind a design-partner application.
Cantina Security and Yeta Labs released apex-flash-1, an open-weight model purpose-built for vulnerability research. Based on Zhipu's GLM-5.3-Flash and RL-trained on 50 real vulnerability cases, it solved 40 of 60 internal test tasks — just 3 fewer than Claude Opus 5 High — at roughly one-thirtieth the cost.
