1. Model Introduction
GLM-Z1-9B-0414 is a dense reasoning-tuned model from Zhipu AI’s GLM-4 series, sized for single-node experimentation. Key highlights:- Dense 9 B architecture: fits comfortably on a single 8-GPU node.
- Reasoning-tuned: post-trained for step-by-step reasoning under the GLM-Z1 line.
- Compatible RL recipe: GRPO with DAPO-style rollout, drop-in replacement for other dense Qwen / LLaMA-class workloads.
