Positioning and release
GLM-Legal is a legal-domain model built on GLM-5.3-Flash and optimized for multi-step professional legal workflows. Zhipu AI announced it on October 12, 2026. The supplied official announcement was indexed but did not return readable page text during this check; its substantive content was also checked against an official AutoClaw publication, dated October 13, 2026. (z.ai)
Capabilities and uses
The model is designed to analyze source materials, apply legal rules, structure arguments and produce task-specific work products. Its training combines legal-domain mid-training with reinforcement learning in simulated legal environments and development of an agent harness. Intended uses include contract review, evidence analysis, legal research, document drafting and compliance planning. Some demonstrated document-editing and retrieval capabilities depend on the surrounding agent platform and tools, not the model alone. (autoclaw.z.ai)
Zhipu reports a 19.2% all-pass rate on Harvey LAB across workflows in 24 practice areas, 12.5 percentage points above the base model. It also reports competitive LegalBench and PLawBench results; the company says the Harvey LAB and LegalBench evaluations were independently conducted by Vals. These are benchmark results, not guarantees for individual matters. (autoclaw.z.ai)
Access and limitations
The announcement invites users to apply for API access. Legal outputs can contain errors or unsupported citations: qualified professionals should verify the cited law, evidence, jurisdiction and conclusions before relying on them. Confidential material should be handled according to applicable professional obligations and the service's data terms. (autoclaw.z.ai)
Pricing
The international Z.ai pricing page lists the specifically named GLM-5.3-FlashX-Legal at USD $0.37 per million input tokens, $0.075 per million cached input tokens, and $1.25 per million output tokens; cached input storage is listed as free for a limited time. The official AutoClaw publication describes GLM-5.3-FlashX-Legal as a legal-workflow model with the same stated Harvey LAB result, but the announcement and price page use different names; the quoted rates apply to the specifically listed version and should not be assumed to apply to every GLM-Legal access arrangement.
