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.

Anonymous Model Omen Alpha Appears on OpenCode

According to BlockBeats, a new anonymous model named Omen Alpha has appeared on the OpenCode platform, with its data page directly attributing it to Zhipu AI. Zhipu has not officially acknowledged the model or disclosed its specific identity. This comes just nine days after the company's previous anonymous model was revealed.

Pricing and Comparison

Previously, Zhipu had tested GLM-5.3-Flash under the alias Ox Alpha for free on OpenRouter and OpenCode, officially unveiling it on August 26 and releasing model weights. Unlike that free test, Omen Alpha is only available to OpenCode Go subscribers paying $10 per month, which includes $100 worth of Omen usage. The pricing is $0.20 per million input tokens and $0.66 per million output tokens, roughly 30% higher than the official price of GLM-5.3-Flash. However, GLM-5.3-Flash is currently offered at a 50% discount, making the effective cost of Omen Alpha about 1.6 times higher.

Specifications and Speculation

No official specifications for Omen Alpha have been released. OpenCode has not disclosed context length, input modalities, or maximum output. The community speculates that Omen Alpha could be a new GLM-5.x iteration or an Omni variant.
