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 |
