GLM-5 — Frontier Open Weights Trained on Ascend, Not NVIDIA
Zhipu AI (Z.ai) released GLM-5 (~745B open-weight MoE, Feb 11–12): trained entirely on Huawei Ascend + MindSpore—no NVIDIA. Competitive coding/agentic claims vs proprietary peers; MIT-style open licensing reported; HK-listed shares jumped ~28–34% on the news. Sovereignty stack as the trade.
Export controls were supposed to freeze China’s frontier stack at the GPU layer. Zhipu’s proprietary demonstration with GLM-5: frontier-class open weights trained entirely on domestic Ascend—capability without the NVIDIA bill of materials.
Zhipu AI (Z.ai) released GLM-5 around February 11–12. Reported scale: 744–754B parameters (MoE in some descriptions)—commonly rounded ~745B. Trained exclusively on Huawei Ascend with MindSpore—company and wire framing as self-reliant stack under U.S. export controls. Positioning: strong coding and long-running agent tasks; tops several open-source leaderboards in contemporaneous reports; approaches or matches aspects of leading proprietary models at substantially lower cost (vendor/coverage). Open licensing (MIT-style references in coverage); weights via Hugging Face and Chinese platforms. Market: Hong Kong-listed shares rose sharply (**28–34%** gains cited across reports); demand reportedly overwhelmed initial capacity, with pricing adjustments in some channels.
Claims vs checks
Ascend/MindSpore training claim and open release are company + Reuters-linked primary reporting. Parameter counts vary slightly across reports (~744–754B)—cite ranges, don’t invent a single audited figure. Bench “matches Claude/GPT/Gemini” claims are vendor/secondary—verify on Artificial Analysis / OpenRouter rankings for the February window. Stock moves are market fact; they are not model quality.
Limits
- Domestic-chip training success ≠ identical serving economics outside China.
- Open license terms: confirm exact SPDX on the model card, not headlines.
- Evaluation transparency and safety practice details remain thinner than U.S. system cards.
