How to run yi locally

  1. 1.Install Ollama for Windows, macOS or Linux.
  2. 2.Run this in a terminal:ollama run yi:6b-v1.5-q4_0
  3. 3.The weights download on first run, then an interactive prompt opens.

Frequently asked questions about yi

How much VRAM do I need to run yi?
At 4K context, the smallest published build of yi (Q4_0) needs roughly 5.0 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 yi 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 5.0 GB of free RAM for the smallest build.
How big is the yi download?
The smallest published build is 3.2 GB. There are 63 builds in total, the largest being 64.1 GB. Leave some extra free disk space beyond the download itself.
How do I run yi locally?
Install Ollama, then run "ollama run yi:6b-v1.5-q4_0" in a terminal. The weights download on first use and an interactive session opens.
