GLM-5.3 Flash measured 11.8x cheaper than Gemini Flash, hitting the Pareto frontier
PawelHuryn · x · 2026-08-28
Paweł Huryn reports his measurements: GLM-5.3 Flash is 1.9x cheaper than DeepSeek V4-Flash, 11.8x cheaper than Gemini 3.7 Flash, and 24x cheaper than Opus 4.8 (high).
He argues it won't dominate DeepSWE but currently lands on the Pareto frontier, with open weights. He also notes the 50% off promotion on OpenRouter (till Sep 9) may be extended, as seen in the past.
