⚡️ GLM 5.3 Flash pushes the Pareto frontier

With an intelligence index around 57.5, the model costs about $0.09 per task and already sits on the Pareto frontier. Until September 9, Z AI offers a 50% discount, so during the promo the price drops to roughly $0.05 per task, pushing the frontier even further.
