# Z.ai — GLM-5.2 > AI lab announcements, news reports and podcasts. forck.live follows what companies announce about their own products. Press may corroborate an official story; it never leads and never appears as an item of its own. A missing date stays missing. A title is the publisher's words — where a company does not publish in English, an English rendering is listed separately as `Title in English` and named as this site's translation, never as theirs. This file is the record of one model version: what the model registry states about it, Z.ai's launch post, the first-party posts this record holds about it, the outlets that reported on those posts, and other companies' announcements that it runs on their platforms. A model ranks nothing here and nothing is composed: each date names whose it is, and a field nothing states is `not stated` rather than missing. - This model's page: https://forck.live/models/glm-5-2 - Z.ai's page: https://forck.live/company/z-ai - Every model: https://forck.live/models - Catalogue: https://forck.live/llms.txt ## Model - Name: GLM-5.2 - Company: Z.ai (z.ai) - Launch post: GLM-5.2: Built for Long-Horizon Tasks — https://forck.live/items/1483-glm-5-2-built-for-long-horizon-tasks - Announced: 2026-06-17T09:01:25+00:00 - Launch source: https://huggingface.co/blog/zai-org/glm-52-blog - Launch chosen by: the earliest dated release post naming it - Released (per models.dev): 2026-06-13 - Listed (per OpenRouter): 2026-06-16 - Open weights: yes - Posts about it: 1 - Outlets named under its posts: 1 - OpenRouter id: z-ai/glm-5.2 — https://openrouter.ai/z-ai/glm-5.2 - Licence: MIT — from https://forck.live/items/1483-glm-5-2-built-for-long-horizon-tasks - Context window: 1M-token context — from https://forck.live/items/1483-glm-5-2-built-for-long-horizon-tasks ## Posts about it _Z.ai's own posts whose title names GLM-5.2, and its launch post, in the record's order: dated newest first, undated last. The record reads the newest 50 first-party posts mentioning the model, every company's together, so a model mentioned more often than that lists the newest of them._ Every entry is one first-party announcement, and carries the same eight fields in this order before any others: Company · Announced · Category · Coverage · Announcement · Group · Source · Record `Source` is the company's own page the announcement was traced to and `Record` is this site's page for it. Both are safe to cite. `Coverage` is a number of outlets, or `not counted` — which means this record reached no count of its own, never that nobody wrote about it. `Category` is this tracker's own analysis, and is authoritative wherever it is stated. `not stated` means either that nothing has analysed the post yet or that the analysis placed it outside this taxonomy; neither is a verdict about the announcement. `Announcement` is whether the post is news of something the company did, rather than a how-to, a customer story, a changelog listing or a staffing note. `Group` is which of this record's groups the entry falls in, carried on the entry itself so it holds where the groups are headings and where they are not. One of: `models`, `covered`, `announcements`, `routine`. Anything after `Record` is held detail that only some announcements carry. ### Z.ai — GLM-5.2: Built for Long-Horizon Tasks - Company: Z.ai (z.ai) - Announced: 2026-06-17T09:01:25+00:00 - Category: new-model - Coverage: not counted - Announcement: yes - Group: models - Source: https://huggingface.co/blog/zai-org/glm-52-blog - Record: https://forck.live/items/1483-glm-5-2-built-for-long-horizon-tasks Z.AI introduces GLM-5.2, a model for long-horizon tasks with a solid 1M-token context, improved architecture using IndexShare, MIT open-source license, and strong benchmark performance including 81.0 on Terminal-Bench 2.1 and 62.1 on SWE-bench Pro, outperforming its predecessor GLM-5.1 and closing the gap to closed-source frontier models like Opus 4.8 and GPT-5.5 on several benchmarks. ## Who reported on it _Outlets this record can name and link, under the first-party post each one covered. Their number is `Outlets named under its posts` above, and the rows are not totalled again. A post's own `Coverage` can be higher: it counts outlets the signal saw that this record cannot name and link._ ### On: GLM-5.2: Built for Long-Horizon Tasks Record: https://forck.live/items/1483-glm-5-2-built-for-long-horizon-tasks - Techstackups — GLM-5.2 vs Claude Opus: https://techstackups.com/comparisons/glm-5.2-vs-opus --- Record: https://forck.live/models/glm-5-2 Catalogue: https://forck.live/llms.txt Current issue: https://forck.live/feed.md
