stealth-model
Ox Alpha on OpenRouter Tool
A free anonymous stealth model with a 1,048,576-token context window, up to 131,072 output tokens, and text, image, and video input. Genuinely usable and genuinely free right now, with a caveat worth reading first: OpenRouter states it is not the developer or provider, its model page says prompts and completions are retained by the anonymous provider, and other documentation for the same model claims zero retention.
OpenCode Zen (Ox Alpha free tier) Tool
OpenCode's Zen gateway serves 'Ox Alpha,' a free, unlimited, reasoning-mandatory coding model with a load-tested one-million-token context window and no authentication required. Measured at about one second to first token and 35-46 tokens per second. Independent forensics attribute it to the GLM family; the operator has not identified itself, so treat everything you send it as disclosed to an unknown party.
