Figures marked (est.) approximate the KV cache because this model's architecture details are not published. They are indicative rather than exact.
How to run tulu3 locally
- 1.Install Ollama for Windows, macOS or Linux.
- 2.Run this in a terminal:
ollama run tulu3:8b - 3.The weights download on first run, then an interactive prompt opens.
Frequently asked questions about tulu3
- How much VRAM do I need to run tulu3?
- At 4K context, the smallest published build of tulu3 (Q4_K_M) needs roughly 6.9 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 tulu3 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 6.9 GB of free RAM for the smallest build.
- How big is the tulu3 download?
- The smallest published build is 4.6 GB. There are 6 builds in total, the largest being 131.4 GB. Leave some extra free disk space beyond the download itself.
- How do I run tulu3 locally?
- Install Ollama, then run "ollama run tulu3:8b" in a terminal. The weights download on first use and an interactive session opens.
