Lumina Claims Zhipu's GLM 5.5 Is Well Into Post Training, an Unverified Report
GLM 5.5 is well into post training now They seem to have been training internal 32B / 122B / 256B models to merge into the next gen base model which will be GLM 5.5 It's been a couple months since GLM 5.3 so I hope they release this relatively soon
Context
If the claim holds, a new open weights model from one of China's leading labs could arrive soon, adding pressure on both Chinese and American rivals.
Lumina is an X account that posts about AI models and benchmarks. GLM is the family of large language models from the Chinese lab Zhipu AI, also known as Z.ai. The post refers to GLM 5.3 as the most recent release.
Deep dive
Lumina posted on Saturday that GLM 5.5 is well into post training. This is an unverified claim. Zhipu AI has not announced GLM 5.5, and the post does not say where the information comes from.
According to the post, Zhipu seems to have been training internal models of 32B, 122B and 256B parameters that will be merged into the next generation base model, which Lumina says will be GLM 5.5. Lumina adds that it has been a couple of months since GLM 5.3 and says it hopes the new model is released relatively soon.
The attached screenshot shows a highlighted line of text that describes a next generation GLM base model called GLM 5.5, coding post training end to end, quant finance training environments and a coding sandbox, post trained internal 32B, 122B and 256B models merging into the base model, and a research topic on self evolution in financial coding. The post does not identify where the screenshot was taken from, so its origin cannot be confirmed.
The post drew more than 100,000 views, showing strong interest in what Zhipu releases next. Until Zhipu confirms details, the model sizes, the training plan and any timing should be treated as Lumina's claims.
What to expect next
Watch for any official word from Zhipu AI or Z.ai about GLM 5.5, which would confirm or rule out this report. If the model ships, look for its size, its license, whether the weights are open, and how it scores on coding benchmarks against other open models. Also watch whether the finance and coding focus described in the screenshot shows up in the release.
