How large is the GLM-5.3 context window?
No context window was supplied for GLM-5.3, so we do not state one.
Is GLM-5.3 an open-weights model?
Yes, it is recorded as open weights, so you may be able to self-host it. Read the licence before commercial use: we have not reviewed it.
Is GLM-5.3 better than other models?
We cannot say. No quality benchmark for it is published on this site, and the Model Finder orders results by cost, not quality. Use the finder to shortlist models, then test them on your own prompts.
