Top options for Phi-4

The strongest part each vendor offers for Phi-4 at BF16 with 16,384 tokens per user, rentable parts first. Each card is one replica, the fewest accelerators that hold the model, and the line it draws on the graph below. Select a card to plot it.

Tokens per second as users grow

Each line is one replica, the fewest accelerators that hold the model, serving more users at once. It climbs while memory bandwidth is the limit, flattens once compute is, and stops where memory runs out at 16,384 tokens per user. Hover a line to bring it forward.

Size Phi-4 for a tokens per second target

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 Phi-4 need?

The weights take 29.3 GB at the native BF16 precision (29.3 GB at BF16, 14.7 GB at FP8, 8.2 GB at INT4). Each concurrent stream adds 200 KB of KV cache per token: 0.8 GB at 4,096 tokens and 3.4 GB at 16,384 tokens.

What is the bare minimum to run Phi-4?

1 x Instinct MI355X OAM at BF16 with 4,096 tokens of context and one stream. The cheapest live rental for that footprint is 1 x RTX PRO 6000 Blackwell Max-Q Workstation Edition at $0.50 per hour.

How many H100s do you need to run Phi-4?

one H100 at BF16 for 4,096 tokens of context and one stream. For 16,384 tokens and 32 concurrent streams the tensor-parallel group is 2 H100s, and 1,000 tokens per second takes 4 H100s across 2 replicas.

How much does Phi-4 cost per million tokens on an H100?

About $1.32 per million output tokens at BF16, 16,384 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 2 x RTX PRO 6000 Blackwell Max-Q Workstation Edition at $0.72.

What precision does Phi-4 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.
