Local LLM model fit
GLM-4.7-Flash is a 30B GLM-4.7 model. This page estimates Q4 VRAM fit, Ollama command, context planning, and fallback choices for common local AI GPUs.
Local coding agents, terminal workflows, tool-heavy engineering tasks, and 30B-class reasoning on 24GB+ GPUs. Weakness: Requires a recent/pre-release Ollama runtime according to the Ollama page; 19GB Q4 leaves limited headroom on single 24GB GPUs at long context.

|---|---|---|
| Q4 / 4-bit | 19 GB | Default local inference balance |
This is a practical planning estimate, not a benchmark. Real memory use changes with backend, context length, KV cache, quantization file, drivers, and offloading settings.
