Jais 3 7B — 显存、速度与本地部署
作者： Jakub Rusinowski · 最后更新：
The 7B member of Jais 3, Arabic and English, with a 512K-token context and a reasoning mode. 9.0B parameters in the published files. Apache-2.0; official GGUF (Q4_K_M 5.6 GB) and MLX builds.
Jais 3 7B 在 Q4_K_M 下约需 6 GB 显存——量化权重加框架开销，不含 KV 缓存。在 Apple Silicon 上，这部分来自统一内存。
按量化级别的显存与速度
计算基准：NVIDIA RTX 4090 (24 GB)。包含 8K 上下文的 KV 缓存，因此数值高于上方的主数字。
| 量化 | 显存 | 显存 | 速度（估算） | 适配 |
|---|---|---|---|---|
| Q2_K 2.63 bpw | 5 GB | ~144 tok/s | 可运行 | |
| Q3_K_M 3.41 bpw | 5.8 GB | ~123 tok/s | 可运行 | |
| Q4_K_M 4.83 bpw | 7.6 GB | ~98 tok/s | 可运行 | |
| Q5_K_M 5.67 bpw | 8.4 GB | ~87 tok/s | 可运行 | |
| Q6_K 6.56 bpw | 9.4 GB | ~78 tok/s | 可运行 | |
| Q8_0 8.50 bpw | 11.6 GB | ~64 tok/s | 可运行 | |
| F16 16.00 bpw | 20 GB | ~37 tok/s | 可运行 |

Jais 3 的其他尺寸
Jais 3 7B — 常见问题
How much VRAM does Jais 3 7B need?
About 6 GB at Q4_K_M — quantized weights plus framework overhead, before any KV cache. The cache grows with context length and is added on top; the table above folds it in. Apple Silicon counts unified memory toward the same figure.
Does Jais 3 7B run on an RTX 4090 (24 GB)?
Yes. Jais 3 7B needs about 6 GB at Q4_K_M, inside a 24 GB card, at an estimated 98 tokens/sec.
How do I run Jais 3 7B locally?
Install Ollama and run `ollama run jais-3`. That pulls the weights and starts a local OpenAI-compatible endpoint; after the download nothing leaves the machine.
What other sizes does Jais 3 come in?
Jais 3 7B (6 GB), Jais 3 32B (22 GB), Jais 3 375B-A23B (230 GB). Every size shares the family's training and licence; the larger ones score higher and need proportionally more memory.
