Z.ai released a legal‑focused AI model called GLM‑Legal. Built on the GLM‑5.3‑Flash architecture, it achieved a 19.2% all‑pass rate on Harvey’s Legal Agent Benchmark. That score is almost three times higher than the model’s baseline. In the test, it outperformed Claude Fable 5 and Kimi K3. The benchmark costs $0.15 per test and access requires an application.

Why it matters

Law firms that can apply for access may evaluate a cheaper, higher‑perform AI tool for legal research and document review.
