Best AI Models for NVIDIA H200 NVL (141.0GB)
With 141 GB of memory, this is a high-end configuration for local AI. You can comfortably run most open-source LLMs including large 70B parameter models at good quantization levels, making it one of the best setups for serious local AI work.
At this memory tier, nearly every popular open-source model is within reach. You can run Llama 3 70B at Q4_K_M or even Q5_K_M quantization with room to spare, handle coding assistants like DeepSeek Coder 33B at high quality, and easily run any 7B–30B model at full or near-full precision. Context windows remain generous even with larger models, so multi-turn conversations and long-document processing work smoothly.
Runs Well
- 70B models (Llama 3 70B, Qwen 72B) at Q4–Q5
- 30B models at Q6–Q8 quality
- 7B–14B models at full FP16 precision
- Vision models (LLaVA, CogVLM) without compromise
Challenging
- Mixture-of-experts models like Mixtral 8x22B at higher quants
- 120B+ models still require lower quantizations

Frequently Asked Questions
- Can NVIDIA H200 NVL run Qwen3.8 27B?
Yes, the NVIDIA H200 NVL with 141 GB can run Qwen3.8 27B, Muse Glimmer 30B, Gemma 4 26B A4B IT, and 2647 other models. 2488 models run at excellent quality, and 124 at good quality. Check the compatibility table above for the full list with VRAM usage and estimated speed.
- Is NVIDIA H200 NVL good for AI?
The NVIDIA H200 NVL has 141 GB of HBM3e, making it excellent for running local AI models. It supports 2612 models at good quality or better. With 4800.0 GB/s memory bandwidth, it delivers fast token generation speeds. This is an enthusiast-grade GPU that handles most popular open-source LLMs.
- How many parameters can NVIDIA H200 NVL handle?
With 141 GB, the NVIDIA H200 NVL supports models from 3B to 70B+ parameters depending on quantization level. At Q4_K_M (the recommended sweet spot), you can fit roughly 235B parameters. This means 7B models at high quality (Q6/Q8) or 30B+ models at Q4.
- What quantization should I use on NVIDIA H200 NVL?
For the best balance of quality and speed on the NVIDIA H200 NVL, start with Q4_K_M — it preserves ~85% of the original model quality while keeping VRAM usage reasonable. With 24+ GB, you have the headroom to run 7B models at Q5_K_M or even Q6_K for noticeably better output quality. For larger 30B models, Q4_K_M remains the sweet spot.
- How fast is NVIDIA H200 NVL for AI inference?
With 4800.0 GB/s memory bandwidth, the NVIDIA H200 NVL achieves approximately 693 tokens/sec on a 7B model at Q4_K_M — that's very fast, well above conversational speed. A 14B model runs at ~347 tok/s. Token generation speed scales inversely with model size — smaller models are significantly faster.
tok/s = (4800 GB/s ÷ model GB) × efficiency
Smaller models = faster inference. Memory bandwidth is the main bottleneck for token generation speed.
Estimated speed on NVIDIA H200 NVL
~179 tok/s~170 tok/s~408 tok/s~153 tok/sReal-world results typically within ±20%. Speed depends on quantization kernel, batch size, and software stack.
- What's the best model for NVIDIA H200 NVL?
The top-rated models for the NVIDIA H200 NVL are Qwen3.8 27B, Muse Glimmer 30B, Gemma 4 26B A4B IT. The best choice depends on your use case: coding assistants benefit from code-tuned models, while general chat works well with instruction-tuned models like Llama or Qwen.
- What power supply and cooling does NVIDIA H200 NVL need?
The NVIDIA H200 NVL has a TDP of 600 W. A good rule of thumb is to provide at least double the GPU's TDP to cover the rest of the system — that means a 1200 W PSU or larger. At this power level, a high-airflow case matters: aim for at least two front intake fans and one rear exhaust, with tidy cabling so hot air isn't trapped around the card. LLM inference sustains full GPU load continuously — longer and more consistently than most gaming workloads — so also make sure your CPU cooler can keep up under combined load.
