Frequently asked
- Can H200 run Qwen2.5-7B?
- Yes. Qwen2.5-7B needs ≈ 17.5 GB VRAM at fp16 and H200 provides 141 GB. Expected throughput is 187 tokens/sec per GPU.
- How much VRAM does Qwen2.5-7B use?
- About 17.5 GB at fp16, 5.5 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 Qwen2.5-7B 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.
- Where can I rent a H200?
- GPUniq aggregates live H200 offers from verified providers. You can deploy an instance in about a minute and pay hourly with no commitment.
