Notes for this stealth model: 💰 It is free 🔑 This time, the provider does not train on your prompts or completions
Context
Ox Alpha's free preview let developers test an unnamed model using text, images and video in a conversation window of up to one million . OpenRouter's August 20 announcement also said the provider would not train on users' prompts or completions. That is a specific promise about training use; the announcement does not establish a data-retention period.
The model's identity became public six days later: OpenRouter identified it as Z.ai's GLM-5.3-Flash. The subsequent reveal connects the anonymous trial to a named model, allowing readers to place experiences from that preview in the release's history.
- token — The chunk of text a model reads and writes in — roughly three-quarters of a word — and the unit AI usage is billed in.
- context window — The maximum amount of text a model can consider at once — its working memory for the current conversation or task.
