GLM Made Crystal Clear · chapter 3: The Model Lineup, Decoded
The Model Lineup, Decoded
2026-10-12
Below: the paragraph from the book that builds this idea, then the diagram itself, and a recap. About a minute of reading.
Two free-tier models round out the family for cost-sensitive or low-stakes use: GLM-4.7-Flash, described in Z.ai's release notes as "designed as the free-tier version," and GLM-4.5-Flash. Do not confuse GLM-4.7-Flash (the free tier) with GLM-4.7-FlashX in the table above (a separate, paid, lightweight sibling). One letter is the difference between free and billed.
