Quick Answers
- How much VRAM does Glm 4.7 Flash 7B Q5 need?
- Glm 4.7 Flash 7B Q5 needs about 8GB minimum VRAM and 18GB optimal VRAM for a safer local run target.
- Can Glm 4.7 Flash 7B Q5 run on an RTX 3090 24GB?
- Yes. Glm 4.7 Flash 7B Q5 fits comfortably on an RTX 3090 24GB target with 18GB optimal VRAM.
- What is the Ollama command for Glm 4.7 Flash 7B Q5?
- Use ollama run glm-4.7-flash:bf16. Check the Ollama tag glm-4.7-flash:bf16 before running.
- What is the approximate Ollama model size for Glm 4.7 Flash 7B Q5?
- Glm 4.7 Flash 7B Q5 uses the glm-4.7-flash:bf16 Ollama tag. Treat the Q5 7 profile as smaller than the runtime VRAM budget; use 8GB minimum VRAM and 18GB optimal VRAM as the safer sizing numbers.
- How much system RAM does Glm 4.7 Flash 7B Q5 need in Ollama?
- Plan for at least 32GB system RAM alongside 8GB minimum VRAM and 18GB optimal VRAM. More RAM helps if layers spill to CPU or if you run multiple models.
- What is the RAM vs VRAM requirement for Glm 4.7 Flash 7B Q5?
- Glm 4.7 Flash 7B Q5 should be sized by GPU VRAM first: 8GB minimum and 18GB optimal. System RAM should be at least 32GB so Ollama has room for CPU-side layers, context, and the surrounding app process.
- What is Glm 4.7 Flash 7B Q5 VRAM usage on an RTX 3090?
- Glm 4.7 Flash 7B Q5 is comfortable for an RTX 3090 24GB target. The page estimates 8GB minimum and 18GB optimal VRAM, with spill risk marked as moderate at long context.
- Which LocalVRAM profiles share the glm-4.7-flash:bf16 Ollama tag?
- LocalVRAM tracks these profiles for the same Ollama tag or model family: Glm 4.7 Flash 7B Q5 (Q5, 8GB min/18GB optimal); Glm 4.7 Flash 7B Q4 (Q4, 6GB min/16GB optimal); Glm 4.7 Flash 7B Q8 (Q8, 12GB min/22GB optimal); Glm 4.7 Flash 7B FP16 (FP16, 18GB min/30GB optimal). Use the table on this page to compare quantization and VRAM targets before choosing a run command.
- Is Glm 4.7 Flash 7B Q5 benchmark data measured or estimated?
- Glm 4.7 Flash 7B Q5 has a verified RTX 3090 result of 11.236 tokens/s from LocalVRAM benchmark data.
Ollama Model Size and RAM Notes
| Ollama tag | glm-4.7-flash:bf16 |
|---|---|
| Run command | ollama run glm-4.7-flash:bf16 |
| Model size guidance | Q5 quantization, 7 profile; size runtime by VRAM, not download size alone |
| Runtime VRAM target | 8GB minimum, 18GB optimal |
| System RAM planning | 32GB or more when running this tag locally with Ollama |
Download size alone is not a safe runtime budget. Runtime memory also includes KV cache, context length, and GPU layer placement.
Ollama RAM vs VRAM Requirements
| GPU VRAM usage estimate | 8GB minimum / 18GB optimal |
|---|---|
| System RAM requirement | 32GB or more for Ollama runtime headroom |
| RTX 3090 24GB fit | Comfortable |
| CPU spill risk | Moderate at long context |
| Context warning | Longer context increases KV cache memory, so real VRAM usage can exceed short-prompt estimates. |
For Ollama, VRAM is the first fit check. System RAM matters when layers spill to CPU, when context grows, or when the local app stack runs beside the model.
Available Tag Variants and VRAM Targets
| Profile | Quantization | VRAM target | Ollama tag |
|---|---|---|---|
| Glm 4.7 Flash 7B Q5 | Q5 | 8GB min / 18GB optimal | glm-4.7-flash:bf16 |
| Glm 4.7 Flash 7B Q4 | Q4 | 6GB min / 16GB optimal | glm-4.7-flash:bf16 |
| Glm 4.7 Flash 7B Q8 | Q8 | 12GB min / 22GB optimal | glm-4.7-flash:bf16 |
| Glm 4.7 Flash 7B FP16 | FP16 | 18GB min / 30GB optimal | glm-4.7-flash:bf16 |
Ollama library tags often group multiple quantization choices under one model family. LocalVRAM separates them into VRAM profiles so you can pick the right local target.
