According to a MarkTechPost report, Z.ai has released GLM-Legal, a legal AI model built on its GLM-5.3-Flash foundation. On Harvey's Legal Agent Benchmark, the model achieved a 19.2% all-pass rate, which the report says is nearly three times the base model's performance. The cost per test is listed at $0.15.
The report also states that GLM-Legal beats Claude Fable 5 and Kimi K3 on the same benchmark, though it does not provide their exact scores. Access to the model is by application, suggesting a controlled rollout rather than open availability.
Since this is a single source, the claims have not been independently verified. The numbers and comparisons come directly from the MarkTechPost article, and no other sources were available to confirm or contradict them.
