Person
Z.ai CEO and co-founder, previously associated with Tsinghua's Knowledge Engineering Group and data-science research center.
Amazon Bedrock now offers Z.ai's 753B-parameter mixture-of-experts GLM 5.3 as a managed API, available only to eligible enterprise customers. Coding-agent teams can call a model that size without running inference hardware of their own.
Reality
A reverse-engineering walkthrough published September 18th traced a 313MB archive in ZCode's local data directory to a 42,411-file commercial workspace whose Git objects and LFS blobs were 86.6% of the payload.
Reality
DeAlignAI's downloadable FP8 build is the license working exactly as written, while its self-reported 320-of-320 HarmBench run remains unchecked by any outside researcher and measures compliance, not capability.
Reality
The 5 trillion token ceiling only binds if every allocation is claimed and then spent. Until it is, this is a short window to test a rival coding agent on someone else's inference bill.
Reality
Z.ai's August 14 post claims post-training gains for coding agents, but the company's release notes still stop at GLM-5.1 and there is no API endpoint, model identifier or weight download.
