Use a lighter model for the mundane stuff and save the heavy lifting for complex architectural logic or debugging. 2. **Refine Your Prompt Engineering** Vague prompts lead to multiple regenerations, which eat through credits. Instead of "Fix this bug," try a more structured approach: ``` Context: [File A] is calling [File B] Issue: NullPointerException at line 42 Goal: Implement a null check that handles the edge case where the API returns an empty array. ``` Getting it right the first time is the best way to save credits.3. **Batch Your Refactoring** Instead of asking the AI to change one line at a time across five different prompts, group your requirements. I usually list 3-4 related changes in one go. This reduces the number of requests sent to the server and keeps the context window cleaner. 4. **Leverage Local Indexing** Make sure your IDE's local indexing is fully up to date. When the AI has better local context, it makes fewer mistakes, meaning you spend less time asking it to "try again." If you're still hitting a wall, it might be time to look into a hybrid setup—using Copilot for autocomplete and a dedicated LLM agent for deep-dive coding sessions. It's all about balancing the tool to the task. [Next How to Control Multiple Browser Windows with JS →](/en/threads/2392/)
