### π Instructions
- Select a model and enter your question
- Click the "Run" button to start execution
- To stop execution, click the "Stop" button
- View execution status and answers in the "Results" tab
- View complete logs in the "Run Logs" tab
- View conversation history in the "Chat History" tab (if available)
- Configure API keys and other environment variables in the "Environment Variable Configuration" tab
- You can add custom environment variables to meet special requirements
### β οΈ Notes
- Running some models may require API keys, please make sure you have set the corresponding environment variables in the "Environment Variable Configuration" tab
- Some scripts may take a long time to run, please be patient
- If execution exceeds 30 minutes, the process will automatically terminate
- Your question will replace the default question in the script, ensure the question is compatible with the selected model
