AI Training Methods on Cloud GPUs
Full Fine-Tuning
Update all model weights on your proprietary dataset. Requires significant VRAM — 70B models need 4–8× A100 80GB with ZeRO-3 optimizer offloading.
LoRA / QLoRA
Train low-rank adapter matrices instead of full weights. QLoRA cuts VRAM requirements by 4–5×, enabling 70B fine-tuning on a single A100 80GB.
RLHF / DPO
Align models with human preferences using Reinforcement Learning from Human Feedback or Direct Preference Optimization for instruction-following and safety.
Distributed Training
Scale across multiple A100/H100 GPUs with tensor parallelism, pipeline parallelism, and data parallelism. NVLink provides 600 GB/s GPU-to-GPU bandwidth.
GPU VRAM Requirements for Fine-Tuning
Estimates for common model sizes. Actual requirements vary by batch size, sequence length, and optimizer state.
| Method | VRAM Needed | Recommended Config |
|---|---|---|
| Full FT – 7B | ~60 GB | 1× A100 80GB |
| QLoRA – 7B | ~6 GB | Any GPU ≥ 8 GB |
| Full FT – 13B | ~120 GB | 2× A100 80GB |
| QLoRA – 13B | ~12 GB | 1× A100 80GB |
| Full FT – 70B | ~320 GB | 4× A100 80GB + ZeRO-3 |
| QLoRA – 70B | ~48 GB | 1× A100 80GB |

KI-Training FAQ
Welche Frameworks funktionieren auf Vultr GPU-Servern für Training?
Vultr GPU-Instanzen unterstützen alle wichtigen ML-Frameworks einschließlich PyTorch, TensorFlow, JAX und MXNet.
Was kostet GPU-Training auf Vultr?
Cloud-GPU-Training eliminiert anfängliche Hardwarekosten. Die stündliche Preisgestaltung von Vultr ermöglicht es, Trainingseinheiten durchzuführen und nur für die genutzte Rechenleistung zu zahlen.
Kann ich ein 70B LLM auf Vultr GPUs fine-tunen?
Ja. Mit QLoRA oder LoRA Fine-Tuning kann ein 70B-Modell auf 2-4 A100 80GB Instanzen feinabgestimmt werden.
Unterstützt Vultr verteiltes Training?
Ja. Vultr unterstützt Multi-GPU-Instanzen mit NVLink für Tensor-Parallelismus mit PyTorch DDP oder DeepSpeed.
