Hermes 3 70B.
Nous Research's flagship Llama fine-tune — agent-friendly.
1× Nvidia L40S · $0.28/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 Hermes 3 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 Hermes 3 70B.
Hermes 3 70B is Nous Research's Llama 3.1 70B fine-tune optimised for agentic workflows — function calling, structured outputs, role-play. Widely deployed in agent frameworks (AutoGen, CrewAI, Magentic) because of its lower refusal rate vs vanilla Llama.
