Apertus 8B — 显存、速度与本地部署
作者： Jakub Rusinowski · 最后更新：
The small Apertus, covering more than 1,000 languages. Runs on an 8 GB card at Q4.
Apertus 8B 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)。仅含权重与开销：该模型架构未公开，因此未计入 KV 缓存。
| 量化 | 显存 | 显存 | 速度（估算） | 适配 |
|---|---|---|---|---|
| Q2_K 2.63 bpw | 3.4 GB | ~154 tok/s | 可运行 | |
| Q3_K_M 3.41 bpw | 4.2 GB | ~133 tok/s | 可运行 | |
| Q4_K_M 4.83 bpw | 5.6 GB | ~107 tok/s | 可运行 | |
| Q5_K_M 5.67 bpw | 6.5 GB | ~95 tok/s | 可运行 | |
| Q6_K 6.56 bpw | 7.4 GB | ~86 tok/s | 可运行 | |
| Q8_0 8.50 bpw | 9.3 GB | ~70 tok/s | 可运行 | |
| F16 16.00 bpw | 16.8 GB | ~41 tok/s | 可运行 |

如何运行 Apertus 8B
安装 Ollama，然后运行：
ollama run apertus规格
Corroborated — Two or more independent sources agree on these figures, but the model card itself was not retrieved. Treat the numbers as good rather than confirmed. 尚未确认： context, releaseDate, hfModelId.

Apertus 的其他尺寸
Apertus 8B — 常见问题
How much VRAM does Apertus 8B 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 Apertus 8B run on an RTX 4090 (24 GB)?
Yes. Apertus 8B needs about 6 GB at Q4_K_M, inside a 24 GB card, at an estimated 107 tokens/sec.
How do I run Apertus 8B locally?
Install Ollama and run `ollama run apertus`. That pulls the weights and starts a local OpenAI-compatible endpoint; after the download nothing leaves the machine.
What other sizes does Apertus come in?
Apertus 8B (6 GB), Apertus 70B (43 GB). Every size shares the family's training and licence; the larger ones score higher and need proportionally more memory.
