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.

PyTorch FSDPDeepSpeed ZeRO-3Megatron-LM

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.

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.
