Union Alpha is slow on OpenRouter but has good DeepSWE value, user says
The author found Union Alpha extremely slow inside OpenRouter at a 262K context window, but its performance-to-cost ratio on DeepSWE lands between Opus 5 and GLM-5.3, and speculates it may be a GLM-family model.

Union Alpha is extremely slow even inside openrouter with just 262k Context window, even though its performance to cost comparison in DeepSWE came really good, just between Opus 5 and GLM-5.3 i already see many saying it's GLM family model with comparing it against GLM-5.3 Flash and getting similar results could it be GLM or something else?
