Describe your computer

Pick the closest line. Office PC and Mini PC are estimates. Linux and a home server stay in the list. We guess the specs, then hide models that would not fit. The guess stays cautious.

Local AI

A local coding model can explain an error or a file that should not leave the machine.

  • Stack traces from private code stay local
  • Good enough for a single file
  • Works offline

Where it falls short

  • Explanations get vague on a large system
  • It can misread a framework it barely saw

Cloud & apps

Claude and Copilot explain a large unfamiliar codebase more clearly.

Our take

Explain private code locally. Use a cloud model when the code is shareable and the system is large.

Choose local if…

  • The code is private
  • It is one file or one error

Choose cloud if…

  • The system is large
  • You want a clearer walkthrough

How to do it in 3 steps

  1. Open the model page and pick any app under Runs in, for example AnythingLLM, GPT4All or Jan. Each app page links to that maker's own guide.
  2. Open the Qwen2.5-Coder 7B page and check the traffic light for a few kinds of computer.
  3. Follow that official guide. This site does not add its own install steps.

Questions

Does this upload my files?
The local tools on this page don't upload your files. The cloud options in the comparison do.
What does it cost?
Most options are free. A few apps are a one-time purchase, and a few models need a computer with more memory.
What if it will not fit?
Use Check my computer, or turn on the lighter memory filters. A red light on the model page means the file is too big.
