It actually can. I have been using it regularly for past 4 days. It is on sol-low level. I deliberately tested it on a moderately complex task. glm-5.3-flash one-shotted it correctly. Luna max couldn't achieve parity even after 3 total attempts. It was creating java bindings for this project: https://github.com/jeffhajewski/latticedb And here is the binding one-shotted by glm-5.3-flash: https://github.com/jeffhajewski/latticedb/pull/5

In GLM-5.3-Flash

It one-shotted generation of Java bindings for this project: https://github.com/jeffhajewski/latticedb Related PR: https://github.com/jeffhajewski/latticedb/pull/5 The session used ~100K input tokens, ~60K output tokens, and ~80K thinking tokens. I reviewed it using gpt-sol-medium, and it seems to be satisfied with it's work.

In Z.ai confirms Ox Alpha is a new GLM-series model and will release its weights

Show HN: LatticeDB – Like SQLite but for graph databases

We have been using graph DBs more and more at work. I found them painful to work with locally and decided to try and build something better.
