It depends on what you want to do with them.
A good way to think about it:
- 1–2 H100s: prototyping, inference, fine-tuning smaller models
- 4–8 H100s: serious fine-tuning, larger inference workloads, smaller training runs
- 16–64+ H100s: training large models from scratch or heavy distributed training
- Hundreds to thousands: frontier-scale training
If you tell me:
- Training or inference
- Model size (e.g. 7B, 70B, 175B)
- Batch size / latency target
- Whether you’re using FP16, BF16, or quantization
- Your budget
…I can estimate the number of H100s much more precisely.
