Zhipu AI's New Model Omen Alpha Launches on OpenCode Go

After Ox Alpha was confirmed as the GLM-5.3-Flash native multimodal model, another model called Omen Alpha appeared on OpenCode Go's subscription plan on September 4th, with clues pointing to China's Zhipu AI. It's only available to subscribers at $10 per month, but includes a $100 usage credit, with tiered rate limits. According to OpenCode's pricing, Omen Alpha charges $0.20 per million input tokens, $0.66 for output, and $0.04 for cached reads. The Pi page shows it supports a 500k token context window, text and image inputs, up to 128k output tokens, and has reasoning abilities. The community thinks it's a new GLM model, possibly from the GLM-5.x or Omni line.
