This New AI Beats the Best Models... But No One Knows Who Built It

An anonymous model called Stealth/OX Alpha has been offered free on OpenRouter with unusually large capacity, strong coding performance and multimodal features, prompting a forensic scramble that currently points most strongly to Zhipu’s GLM 5.x family. A stealth launch with frontier-scale capacity OX Alpha appeared without a model card, lab attribution or press rollout, yet was described and provisioned like a flagship system. It was offered free for about a week with near-unlimited use, and the operator claimed capacity of 100 trillion tokens a day. The listed specs included a 1,048,576-token context window, 131,072 max output tokens, text, image and video input, plus tool calling and structured JSON support.
