Zhipu's GLM-5.3: Same Base, Better Coding, Open-Source Crown Shifts
Zhipu AI has unveiled GLM-5.3, a model that keeps the same base as its predecessor but pushes post-training to new heights. With a tenfold increase in training scale and extended reinforcement learning, the model's coding ability jumped by about 50%, topping open-source benchmarks and rivaling closed-source giants. The move signals a shift in AI competition: it's not just about bigger models, but smarter training.
