In this video, we take a hands-on look at GLM-4.7 Flash, a smaller, faster variant of the GLM-4.7 family designed for efficient local inference and coding-focused workloads. The goal of this test is to evaluate whether GLM-4.7 Flash can compete with other popular small and mid-sized coding models while maintaining strong reasoning and responsiveness.

We begin with a technical overview and testing setup, then move into a wide range of real-world tasks. These include browser-based OS interactions, iterative result refinement, 3D printer simulations, comparisons against GPT-OSS and Qwen3 models, music and drum kit simulations, flight simulators, roleplay and logic testing, website generation, and Python-based 3D FPS game creation.
