Frequently Asked Questions

How much VRAM do I need to run a OLMo model?
The smallest OLMo model, OLMo 1B HF, runs from 1.3 GB of VRAM at Q4_K_M (smaller low-bit quantizations start at 1.1 GB with a noticeable quality loss). Larger family members need proportionally more — see the table above for every model.
Which OLMo models can I run on a 16 GB GPU?
15 of 22 OLMo models fit in 16 GB of VRAM at Q4_K_M, including OlmOCR 2 7B 1025, OLMoE 1B 7B 0924 Instruct, Olmo 3 7B Instruct.
What is the most popular OLMo model to run locally?
Olmo 3 32B Think is the most downloaded OLMo model in local-friendly quantized formats. It runs from 21.5 GB of VRAM at Q4_K_M.
