Has GLM-5.5 been officially released?
No. The current Z.ai API catalog, model overview, and developer documentation do not list GLM-5.5. DataLearner marks it as a rumored unreleased model.
GLM-5.5
Also known as: GLM 5.5 / GLM5.5
GLM-5.5 is a community name for a rumored next-generation Z.ai model. As of September 8, 2026, official Z.ai catalogs do not list it; parameters, API identity, pricing, tools, reasoning modes, and benchmarks remain unknown.

GLM-5.5 is a community label for a possible next-generation model from Zhipu AI / Z.ai, not an officially published product name. As of September 8, 2026, the public Z.ai and BigModel catalogs list GLM-5.3, GLM-5.3-Flash, GLM-5.2, and other models, but no GLM-5.5 model card, API identifier, pricing page, or release announcement. DataLearner therefore lists this as a rumored unreleased model; the catalog date is a placeholder under the unreleased-model convention, not an official release date.
The available leads are Chinese-language secondary reports. A Huskytech WeChat article dated July 21, 2026 claims that the next GLM could reach trillion-scale size and target frontier models. A more recent article explicitly labeled “unverified rumor” repeats an overseas X post about GLM-5.5 parameters. Neither provides a verifiable Z.ai announcement, public model identifier, or API response, and the claimed numbers conflict.
Z.ai has not published an API model ID, parameter count, active parameters, context window, maximum output, modalities, tool support, reasoning modes, weights, license, prices, or public benchmark results for GLM-5.5. DataLearner does not copy these fields from GLM-5, GLM-5.2, or GLM-5.3, and does not promote trillion-scale or multi-trillion parameter rumors into structured facts.
No. The current Z.ai API catalog, model overview, and developer documentation do not list GLM-5.5. DataLearner marks it as a rumored unreleased model.
No official values have been published. Conflicting trillion-scale claims in secondary articles are not treated as specifications, so these fields remain unknown.
There is no verifiable official API ID or public benchmark record yet. DataLearner does not copy API, tool, reasoning-mode, pricing, or benchmark data from GLM-5.3 or other predecessors.
