Local LLMs are excellent pair programmers. Here is a workflow to maximize their utility.

1. Explaining Legacy Code

Paste a complex function into the chat and ask: > "Explain this code line by line. Identify any potential edge cases or bugs."

2. Generating Unit Tests

Writing tests is tedious. Let the AI do it. > "Write Jest unit tests for the following TypeScript function. Include positive and negative test cases."

3. Refactoring

> "Refactor this Python script to follow PEP 8 standards and improve variable naming for readability."

Recommended Models

• DeepSeek Coder V2: State of the art for coding.
• Qwen 2.5 Coder: Excellent all-rounder.
• StarCoder2: Good for code completion.
