OpenCode's Anonymous Model Omen Alpha Leaked as Zhipu GLM, Priced ~1.6x GLM-5.3-Flash
teortaxesTex · x · 2026-09-04
OpenCode has launched an anonymous model, Omen Alpha, and its own data page appears to list it under Zhipu — though Zhipu has not officially claimed it or revealed which GLM it is.
Key facts:
- It comes just 9 days after GLM-5.3-Flash was revealed as the anonymous Ox Alpha (officially announced August 26 with open weights)
- No free lunch this time: Omen Alpha is only available to OpenCode Go subscribers at $10/month, with a plan offering $100 of Omen usage
- Pricing is $0.20/M input tokens and $0.66/M output — about 30% above GLM-5.3-Flash's list price, and roughly 1.6x its current 50%-off price
- Official specs (context length, modalities, max output) remain blank; the community speculates it could be a new GLM-5.x or an Omni branch
One observer noted the pricing almost exactly matches Zhipu's off-peak V4-Flash rates (1.5/4.5 RMB).
