Z.ai releases GLM-5.3, matching frontier coding benchmarks

Z.ai's GLM-5.3, a ~750B-parameter model, surpasses Moonshot AI's Kimi K3 on many benchmarks and exceeds Claude Fable 5 or GPT-5.6-Sol on some. It's the same base model as GLM-5.2 with extended post-training, currently in the coding plan, with API access soon and open weights on Hugging Face in two weeks.
