Zhipu AI Launches Anonymous Model Omen Alpha on OpenCode, Priced Higher Than GLM-5.3-Flash

Zhipu AI has released another anonymous model, Omen Alpha, on the OpenCode platform, just nine days after the official unveiling of GLM-5.3-Flash (previously known as Ox Alpha). The data page on OpenCode already lists the model under Zhipu AI, though the company has not formally acknowledged it. Omen Alpha is only accessible to OpenCode Go subscribers at $10 per month, with a $100 usage credit. The pricing is $0.20 per million input tokens and $0.66 per million output tokens, about 30% higher than GLM-5.3-Flash's official price. However, GLM-5.3-Flash is currently 50% off, making Omen Alpha approximately 1.6 times more expensive at the discounted rate. Detailed specifications such as context length, input modalities, and maximum output have not been disclosed. The community speculates it could be a new GLM-5.x or Omni variant.
