Frequently asked questions about smallthinker

How much VRAM do I need to run smallthinker?
At 4K context, the smallest published build of smallthinker (Q4_K_M) needs roughly 3.2 GB of GPU memory once weights, KV cache, compute buffers and runtime overhead are counted. Bigger quantizations and longer context windows need more. It can also run partly or entirely on the CPU using system RAM, more slowly.
Can I run smallthinker without a dedicated GPU?
Yes, but slowly. Without a GPU the model runs on the CPU using system RAM, which usually means a few tokens per second rather than dozens. You would need at least 3.2 GB of free RAM for the smallest build.
How big is the smallthinker download?
The smallest published build is 2.0 GB. There are 3 builds in total, the largest being 6.3 GB. Leave some extra free disk space beyond the download itself.
How do I run smallthinker locally?
Install Ollama, then run "ollama run smallthinker:3b-preview-q4_K_M" in a terminal. The weights download on first use and an interactive session opens.
