How much VRAM it needs
Weights plus runtime overhead, then the KV cache that grows with the context you serve.

Cross-checked on Hugging Face Oct 28, 2026: 684.5B parameters in the safetensors headers, 688.6 GB of weight files, attention layout from config.json (61 layers, latent rank 512). Method: weights as published at the native precision, verified on Hugging Face 2026-10-28; other precisions estimated at 1 (8-bit) and 0.6 (4-bit) bytes per parameter; × 1.2 runtime headroom; KV cache = 1152 bytes per token per layer × 61 full-attention layers (FP16 cache, one sequence).config.json ↗
What it costs to run, GPU by GPU
The fewest GPUs of one type whose total memory fits the model at short context, priced from the cheapest eligible on-demand offer for exactly that count (45-day window, newest reading per provider), with the next providers beside it. Monthly = 730 hours.
