Deep Cogito3B~3 GB VRAM at Q4_K_M

Cogito v1 3B — VRAM, speed & local setup

Written by Jakub Rusinowski · Last updated

Entry-level Cogito variant for edge devices and 4–6 GB VRAM GPUs. Despite its small size, the dynamic reasoning toggle outperforms Llama 3.2 3B on math and logic tasks. Runs on laptop integrated graphics (NPU-accelerated). Great for offline assistants.

Cogito v1 3B needs about 3 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

Quoted against NVIDIA RTX 4090 (24 GB). Includes the KV cache at 8K context, so it reads higher than the headline figure.

Can I run Cogito v1 3B on my GPU?

Other Cogito v1 sizes

Cogito v1 3B — frequently asked questions

How much VRAM does Cogito v1 3B need?

About 3 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 Cogito v1 3B run on an RTX 4090 (24 GB)?

Yes. Cogito v1 3B needs about 3 GB at Q4_K_M, inside a 24 GB card, at an estimated 190 tokens/sec.

How do I run Cogito v1 3B locally?

Install Ollama and run `ollama run cogito:3b`. That pulls the weights and starts a local OpenAI-compatible endpoint; after the download nothing leaves the machine.

What other sizes does Cogito v1 come in?

Cogito v1 3B (3 GB), Cogito v1 8B (6 GB), Cogito v1 14B (9 GB), Cogito v1 32B (20 GB), Cogito v1 70B (43 GB). Every size shares the family's training and licence; the larger ones score higher and need proportionally more memory.
