GLM 5.2: open weights with a million-token context
GLM 5.2 pairs open weights with long context and mid-tier coding results — interesting for self-hosting teams that can carry integration and serving work.
What changed
- Z.ai published GLM 5.2 as a 744B open-weight model with multimodal input.
- Hosted API pricing undercuts several closed balanced tiers.
- Ecosystem tooling is thinner than the major closed labs.
Best fit
- Open-weight deployments
- Long context on a budget
- Coding workloads
What to be careful about
- 744B is not a laptop deployment — plan serving, quantisation, and ops honestly.
- Integration and evaluation time can erase token savings.
- GLM Coding Plan now defaults to GLM 5.3 and routes 5.2/5.1 requests there — this row is the open-weight / token-list identity.
Dataset snapshot: GLM 5.2 is also represented in the checked comparison dataset. Prices and benchmark figures carry their own field dates.
