Cheapest hardware per quantisation.
Each row is one quantisation tier (the same weights compressed differently). Lower precision → lower VRAM → cheaper hardware, at the cost of small accuracy loss. $/hr refreshed hourly from each provider's API.

Bill breakdown.
Rent the GPU instead of paying per token.
For an open-weights model like NVIDIA: Nemotron 3 Ultra, you can rent a GPU and serve inference yourself. The math: cheapest GPU rental × 730 hours/month + your electricity rate × power draw.
Assumes the GPU runs 24/7 at ~85% utilisation. If your traffic is bursty, you'll pay less for the API and probably more for the GPU (idle hours still cost rental). The breakeven analysis lives on the Self-host vs API breakeven tool.
About NVIDIA: Nemotron 3 Ultra.
An open-weights text model in NVIDIA's Nemotron 3 family, with 550B parameters and 55B active per token. It shares the family's LatentMoE design of Mamba-2, mixture-of-experts and attention layers, supports up to 1M tokens of context, and lets you turn reasoning on or off. NVIDIA recommends it for complex multi-step agents, long-context analysis, tool use, multilingual work and retrieval, and lists 8x B200-class GPUs, 8x H200 or 16x H100 as the minimum for the BF16 weights. The licence is OpenMDW-1.1.
