Work through questions, brainstorm ideas, and try local reasoning without a large download.

  • 4 min read
  • ~8 GB RAM to start
  • 2.5 GB download

A compact choice for everyday writing and trying local reasoning. Provide the facts it should use, then ask for a focused answer.

Where it works well

  • A practical download size for an everyday laptop.
  • Reasoning and general text tasks in the same model family.
  • Drafting, brainstorming, and multilingual conversations.

Common use cases

  • Compare two purchases using specifications you paste in.
  • Turn an outline into a first draft.
  • Work through a small planning problem with explicit constraints.

Know its limits

  • Difficult math and detailed coding still need independent checks.
  • An 8 GB machine has little spare memory when several apps are open.
  • It has no built-in access to current prices or the web.

Run it on your computer

Start with a compressed download and a short conversation. Our estimate is about 8 GB of total RAM or Mac unified memory, with room for the operating system. The listed 2.5 GB download is the model file, not its full running memory use.

Check the model’s supported runtime and hardware before loading it. System RAM on a PC and unified memory on a Mac are different from dedicated NVIDIA VRAM. A memory match doesn’t guarantee compatibility or speed. Choose a smaller model if responses are too slow.

Use a desktop app that supports the listed model format, such as LM Studio or Ollama. Download the exact local variant, load it in Chat, and start with one small task. Model downloads need internet; local chat can work offline once the model is downloaded.
