GLM 4.5 Flash takes the generous spirit of FLASH and injects a larger knowledge core plus reasoning‑specific pretraining. It excels at structured tool invocation, complex coding tasks, and multi‑step analytical chains, outperforming many paid models in academic benchmarks. An open‑weight policy combined with Apache 2 licensing encourages experimentation and derivative research. Low memory footprint and support for interpreter mode let it act as the brain of autonomous agents on modest hardware. Whether powering coding bootcamp tutors or acting as the analysis engine inside robotics software, GLM 4.5 Flash delivers top‑shelf capability for zero licensing cost.
