Model library → OLMo 2 → OLMo 2 7B Instruct

A fully open 7B model with competitive performance. Training data and code fully published under Apache 2.0. Great for academic research, education, and deployments requiring complete transparency.

OLMo 2 7B Instruct needs about 5 GB of VRAM at Q4_K_M — quantized weights plus framework overhead, before any KV cache. On Apple Silicon that figure comes out of unified memory.

VRAM and Speed by Quantization

Modelled on a reference NVIDIA RTX 4090 (24 GB), at 8K context. Speed figures are ESTIMATES from the memory-bandwidth roofline described on the methodology page, not benchmarks we ran — rows marked measured come from published or reader-submitted runs. VRAM here includes the KV cache, so it reads higher than the headline figure above, which does not.

OLMo 2 7B Instruct — Frequently Asked Questions

How much VRAM does OLMo 2 7B Instruct need?
About 5 GB at Q4_K_M — quantized weights plus framework overhead, before any KV cache. The cache grows with context length and is added on top; the table above folds it in. Apple Silicon counts unified memory toward the same figure.
Does OLMo 2 7B Instruct run on an RTX 4090 (24 GB)?
Yes. OLMo 2 7B Instruct needs about 5 GB at Q4_K_M, inside a 24 GB card, at an estimated 92 tokens/sec.
How do I run OLMo 2 7B Instruct locally?
Install Ollama and run `ollama run olmo2:7b`. That pulls the weights and starts a local OpenAI-compatible endpoint; after the download nothing leaves the machine.
What other sizes does OLMo 2 come in?
OLMo 2 7B Instruct (5 GB), OLMo 2 13B Instruct (9 GB). Every size shares the family's training and licence; the larger ones score higher and need proportionally more memory.
