What Is the GLM 5.5 Model?
GLM 5.5 is the expected next large language model from Zhipu AI (Z.ai), the team behind GLM 5 and the previous flagship.
The next step in the GLM family
GLM 5.5 refers to the anticipated next-generation large language model from Zhipu AI (Z.ai). As of August 2026, it has not been officially announced; the latest Z.ai flagship remains the previous flagship, released on June 16, 2026.
A release tracker, not a rumor mill
This page records what Z.ai has publicly confirmed, marks every unconfirmed detail — release date, GLM 5.5 size, and it pricing — as unconfirmed, and keeps speculation clearly labeled as speculation.
What the model line already tells us
Each recent release has advanced coding, long-horizon reasoning, and agentic workflows while keeping open weights and low-cost API access. A GLM 5.5 model is expected to continue that trajectory, subject to official confirmation.

What to Expect from the GLM 5.5 Model
Expectations for the new model come from the model line's trajectory, not from an official spec sheet.
Coding and long-horizon tasks
Every recent release has focused on coding and long-horizon workflows. The model is expected to build on that pattern rather than redefine it.
Agentic workflows
the previous flagship emphasizes agentic engineering with tool use and effort-level control. A GLM 5.5 release would likely keep strengthening autonomous multi-step workflows.
Open weights
Z.ai has open-sourced models under the MIT license. Community expectations for open source follow that precedent until an announcement says otherwise.
Cost-efficient access
Pricing has stayed a fraction of comparable frontier models. Pricing is unannounced but expected to stay competitive.
