Not out yet. Zhipu AI hasn't released GLM-5.5; the latest signal, on August 4, 2026: A GLM-5.3 leak says days away — we reported 5.3 was being skipped, and we are not moving. What we know so far: still expected — open weights; 1M ctx; size claims span 1T–3T; Oct 10: rumor from @ChrisGPT, citing informants close to Z.ai, puts it next week or late October; Zhipu has given no date and no GLM-5.5 id is in the catalogs we sweep (Oct 10). Swept every 60 seconds across provider catalogs. The moment it answers on a public API, alerts fire: a text or a call on paid plans the second it's confirmed, then a free Chrome push and email about 15 minutes later.
