Community speculation suggests Cloudflare's first-ever stealth model, "Union Alpha," may be a rebranded Zhipu GLM model. The guess was sparked by Plinius mentioning GLM-5.4 in a thread with opencode, though current thinking in the discussion points to GLM 4.5 rather than a router or a new model. Its true identity remains unconfirmed.
