+# FAQ
+
+### Can MidScene smartly plan the actions according to my one-line goal? Like executing "Tweet 'hello world'"
+
+MidScene is an automation assistance SDK with a key feature of action stability — ensuring the same actions are performed in each run. To maintain this stability, we encourage you to provide detailed instructions to help the AI understand each step of your task.
+
+If you require a 'goal-to-task' AI planning tool, you can develop one based on MidScene.
+
+Related Docs:
+* [Tips for Prompting](./prompting-tips.html)
+
+### Limitations
+
+There are some limitations with MidScene. We are still working on them.
+
+1. The interaction types are limited to only tap, type, keyboard press, and scroll.
+2. It's not 100% stable. Even GPT-4o can't return the right answer all the time. Following the [Prompting Tips](./prompting-tips) will help improve stability.
+3. Since we use JavaScript to retrieve items from the page, the elements inside the iframe cannot be accessed.
+
+### Which LLM should I choose ?
+
+MidScene needs a multimodal Large Language Model (LLM) to understand the UI. Currently, we find that OpenAI's  GPT-4o performs much better than others.
+
+### About the token cost
+
+Image resolution and element numbers (i.e., a UI context size created by MidScene) form the token bill.
+
+Here are some typical data.
+
+|Task | Resolution | Input tokens | Output tokens | GPT-4o Price |
+|-----|------------|--------------|---------------|----------------|
+|Find the download button on the VSCode website| 1920x1080| 2011|54| $0.011|
+|Split the Github status page| 1920x1080| 3609|1020| $0.034|
+
+> The price data was calculated in June 2024.
+
+### The automation process is running more slowly than it did before
+
+Since MidScene.js invokes AI for each planning and querying operation, the running time may increase by a factor of 3 to 10 compared to traditional Playwright scripts, for instance from 5 seconds to 20 seconds. This is currently inevitable but may improve with advancements in LLMs.
+
+Despite the increased time and cost, MidScene stands out in practical applications due to its unique development experience and easy-to-maintain codebase. We are confident that incorporating automation scripts powered by MidScene will significantly enhance your project’s efficiency, cover many more situations, and boost overall productivity.
+
+In short, it is worth the time and cost.

 # Tips for Prompting
 
-There are certain techniques in prompt engineering that can help improve the understanding of user interfaces.
+The natural language parameter passed to MidScene will be part of the prompt sent to the LLM. There are certain techniques in prompt engineering that can help improve the understanding of user interfaces.
 
 ### The purpose of optimization is to get a stable response from AI
 
-Since AI has the nature of heuristic, the purpose of prompt tuning should be to obtain stable responses from the AI model across runs. In most cases, to expect a consistent response from GPT-4 by using a good prompt is entirely feasible.

-Bad ❌: "Lower Part of page"
+Bad ❌: "Search 'headphone'"
 
 ### Infer from the UI, not the DOM properties
 
 All the data sent to the LLM are the screenshots and element coordinates. The DOM is almost invisible to the LLM. So do not expect the LLM infer any information from the DOM (such as `test-id-*` properties).
 
 Ensure everything you expect from the LLM is visible in the screenshot.
