Someone could've trained model on top of GLM. Same way Cognition trained their SWE model on top of Kimi and Cursor did same with their Composer model.

While possible the amount of variation in serving infrastructure is unlikely to land with actually giving the exact same errors zhipu does.

It feels like glm flash, and there was a report zhipu had secured a huge new cluster suggesting they have the capacity. My guess anyway.

The reasoning levels are the same as GLM 5.3. GLM 5.3 is still not open...

I believe it's GLM 5.3 Flash or Air.
