 ## How It Works
 
 The AI Code Reviewer GitHub Action retrieves the pull request diff, filters out excluded files, and sends code chunks to
 the OpenAI API. It then generates review comments based on the AI's response and adds them to the pull request.
 
+## Tips & Tricks
+
+* The `gpt-4` model is powerful, but [relatively expensive](https://openai.com/pricing) and does not support
+  [JSON Mode](https://platform.openai.com/docs/guides/text-generation/json-mode) at the time of writing. Consider using
+  one of the turbo models — such as `gpt-4-turbo-preview` or `gpt-3.5-turbo` — to find the right balance between price
+  and performance.
+* Use `custom_prompts` to hone the action's analysis in on things you care about, and to avoid things you don't. There
+  is no point, for example, in having the action repeat what your static analysis tooling does for you in real-time
+  while coding.
+* Use an `if: '! github.event.pull_request.draft'` job conditional and `ready_for_review` trigger to control costs and
+  ensure that you are only running the action on pull requests that are truly ready to be reviewed.
