Llama 3.1 70B.
Llama 3.1 70B — production workhorse, superseded by 3.3 but still widely deployed.
1× Nvidia RTX 6000 Ada · $0.27/hr.
Most-aggressive quantisation we have a working recommendation for. Lower precision = less VRAM = cheaper hardware, at a small accuracy cost.

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.

Rent the GPU instead of paying per token.
For an open-weights model like Llama 3.1 70B, 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 Llama 3.1 70B.
Llama 3.1 70B was the flagship 70B model for the latter half of 2024. Llama 3.3 70B (Dec 2024) replaced it with same architecture + better post-training, but many production deployments still pin to 3.1 70B for reproducibility. Same VRAM footprint, same context, same tokenizer as 3.3.
