Frequently asked

Can H200 run Llama 3.3 70B?
Not at fp16 — Llama 3.3 70B needs about 142.9 GB while H200 has 141 GB. It fits at INT4 quantization (40.9 GB) with some accuracy trade-off.
How much VRAM does Llama 3.3 70B use?
About 142.9 GB at fp16, 40.9 GB at INT4 (for a 4K context, batch size 1). Longer contexts add to KV cache size; larger batches increase activations.
What's the fastest way to run Llama 3.3 70B on H200?
Use a production inference engine like vLLM, SGLang, or TensorRT-LLM with paged attention — they cut KV cache 2–3× vs the naive estimate and batch multiple requests efficiently. For H200, enable Flash Attention 2.
