Mystery 'Stealth Ox Alpha' Model Lands on OpenRouter: 1M Context, 131K Output & DeepSWE Coding Prowess
An anonymous frontier AI model labeled 'stealth/ox-alpha' appeared unexpectedly on OpenRouter on August 20, 2026. Boasting a 1,048,576-token context window, 131,072-token generation limits, and multimodal video support, tokenizer fingerprinting strongly suggests it originates from top Chinese lab Zhipu AI.
