Task Description
In this shared task, your goal is to build a solution that, given a set of documents, can (1) find the correct answer to a multiple-choice question and (2) identify the document and page where the answer was found.
The competition will run on Kaggle in the code-only mode, which means that you will submit your solution as code, e.g., a Python script or notebook, rather than submitting just test answers. Your solution should be able to run on a single P100 GPU and complete all test sets prediction within 9 hours. The code-only mode will facilitate fair competition.
You are free to use any open-source embeddings and large language models of your choice — just keep in mind the compute limitations, which may not allow you to use the larger LLMs.
We encourage you to use LLMs specifically trained to work with the Ukrainian language, like LapaLLM and MamayLM.
