Our take
Written Sep 2, 2026GLM 5 is a large downloadable text model from Z.ai with a permissive MIT licence and a 204,800-token request limit. Its strongest measured skill is coding, with a 72.8% score on real-world software engineering tasks, though its maths and creative writing scores trail that peak.
Pick this for coding-heavy workloads or end-to-end software engineering where you need open weights and a permissive licence. Use it for long-context text work at 204,800 tokens, or when you want provider choice with a competitive floor rate. Skip it if you need multimodal input, if maths or creative writing matter more than code, or if you want the fastest throughput without paying a steep premium.
The case for it
- Strongest measured skill is coding: 39.8 points above its own overall chat score, and 54.9 points above its maths score.
- Resolves real GitHub issues end-to-end at 72.8% on SWE-bench Verified.
- Permissive MIT licence allows commercial use, modification and redistribution.
- Seventeen hosted offers, with four providers at the same floor rate.
The case against it
- Maths and creative writing lag its coding peak by 49+ points each.
- Premium throughput costs 67% more than the cheapest rate.
- Active parameter count undisclosed, so efficiency versus dense or mixture-of-experts alternatives is unverified in our data.

From the parameter list each endpoint publishes. Streaming is omitted: nothing we hold reports it, for any model.

What we do not know about this model yet
- We hold no measured file for it, so all 3 sizes on this page are calculated from the parameter count.
- 1 of 10 listings publishes no parameter list, so what its API accepts is unknown to us.
- We do not hold the active parameter count for it, so how much of it runs on any one token is unknown to us.
- Nothing we hold says whether an endpoint streams, so we do not show it either way.
- 2 of 10 listings do not say whether they train on prompts, and 1 answers only through OpenRouter, not for its own listing.
- We hold no batch or off-peak rate for any of its listings.
- We hold a decode speed for it, but no prompt-processing (prefill) figure, so how long the input side of a job takes is unknown to us.
