Implement an evaluation framework

We need an evaluation framework to test how well the system works for different types of tasks.

We need to develop or use a framework that supports:

• List(s) of tasks/prompts for different types of tasks
• Example content to index as context for these tasks
• Storing answers of the LLM
• Automated evaluation of the answers with another LLM
• Manual evaluation by a human
• Storing evaluation results
• Generating visualizations how well the LLM performed on different tasks
