Model weights plus 20% for runtime overhead, from measured checkpoint sizes; a stated context length adds its KV cache on top. Each price is the cheapest bookable rate for that exact instance size, for the whole configuration — the cheaper of the two is highlighted and orders the table. A ×N figure is total VRAM across N cards and makes no claim about interconnect throughput.
How this is worked out
Weight sizes are measured from the actual checkpoint files on Hugging Face — never derived from parameter count, which gets quantized releases wrong. On top of the weights we assume 20% for activations, CUDA context and allocator slack. Stating a context length adds its KV cache explicitly, computed only for architectures whose cache shape the config states unambiguously.
A configuration that holds the weights and cache but not that full margin is marked as a tight fit rather than hidden — it will load, and may well run at batch size one, but expect trouble under load.
Prices are the cheapest bookable rate for that exact instance size, refreshed with the rest of the catalog.
