The calculator starts from your traffic instead of a fleet: set a target rate and read the replica count for every GPU.

Frequently asked questions

How much GPU memory does Llama 3.1 Nemotron Ultra 253B need?

The weights take 507 GB at the native BF16 precision (507 GB at BF16, 253 GB at FP8, 143 GB at INT4). Each concurrent stream adds 256 KB of KV cache per token: 1.1 GB at 4,096 tokens and 8.6 GB at 32,768 tokens.

What is the bare minimum to run Llama 3.1 Nemotron Ultra 253B?

2 x Instinct MI355X OAM at BF16 with 4,096 tokens of context and one stream. The cheapest live rental for that footprint is 8 x RTX PRO 6000 Blackwell Max-Q Workstation Edition at $4.00 per hour.

How many H100s do you need to run Llama 3.1 Nemotron Ultra 253B?

8 H100s at BF16 for 4,096 tokens of context and one stream. For 32,768 tokens and 32 concurrent streams the tensor-parallel group is 16 H100s, and 1,000 tokens per second takes 64 H100s across 4 replicas.

How much does Llama 3.1 Nemotron Ultra 253B cost per million tokens on an H100?

About $24.81 per million output tokens at BF16, 32,768 tokens of context and 32 streams, using the cheapest live on-demand price of $1.83 per GPU-hour. The cheapest part per token is 16 x RTX PRO 6000 Blackwell Max-Q Workstation Edition at $14.59.

What precision does Llama 3.1 Nemotron Ultra 253B ship in?

The published checkpoint is BF16. FP8 and INT4 figures describe post-training quantisations that halve and quarter the footprint at a small accuracy cost.

All figures are roofline estimates from the model's config.json and each GPU's published memory, bandwidth and tensor-core peak, with fixed efficiency factors. Prices are the cheapest live on-demand listing per GPU when the site has one. They are a planning floor; a tuned serving stack can do better. Llama 3.1 405B pruned by neural architecture search: 64 of 162 layers keep attention (256 KB per token). NVIDIA's card serves it with tensor parallelism across 8 GPUs.
