Who's who in AIAI glossary
Zhipu AI
Chinese AI lab spun out of Tsinghua University, known for its GLM models released in open weight, meaning freely downloadable. It embodies China's open-source strategy: distributing powerful models for free to compete with closed American models.
In other words
A simple academic spin-off in 2019, it now releases models for free download that rival those that American giants charge for by usage.

- Mistral unveils Large 4, its 1-trillion-parameter giant
Mistral unveils Large 4, a 1-trillion-parameter model trained in Europe, soon to be openly available. A genuine leap, and a gap that remains.
- GLM-5.3-Flash runs on 100,000 Chinese accelerators, at a comparable cost
Z.ai has announced that its flagship open model is deployed on more than 100,000 Chinese accelerators, with throughput tripled in two weeks. We analyse what this claim implies if it is confirmed.
- Ox Alpha revealed: it was GLM-5.3-Flash, and it runs entirely on Chinese chips
Z.ai confirmed on 26 August that the anonymous model Ox Alpha was GLM-5.3-Flash, released under the MIT licence with a one-million-token context. We analyse the reveal, the specs, and the point that goes far beyond the technical.
- OX Alpha: a state-of-the-art model appeared out of nowhere, free, and no one says who built it
An anonymous model named OX Alpha appeared on OpenRouter on 20 August, free of charge, with a million-token context window and multimodal support. No lab has claimed it. Here's a rundown of what we know, what's speculation, and the question no one is asking.
- GLM-5.3: an open model found over a thousand real flaws in widely used software
Z.ai's GLM-5.3 achieves top scores in vulnerability discovery. Unlike previous versions, its weights have not been released: the lab has withheld them for a security assessment. We analyse this precedent.
- GLM-5.2 versus Opus 4.8 and GPT-5.5: China opens the floodgates while the West shuts its own
On 13 June 2026, Zhipu AI released GLM-5.2 under the MIT licence, the day after Washington cut off Fable 5 and Mythos 5. We break down what this open model is worth against Opus 4.8 and GPT-5.5, and what it changes for the general public and for businesses alike.
