Description Automatic text summarization (ATS), alongside neural machine translation or question answering, is one of the leading tasks in Natural Language Processing (NLP). In recent years, ATS has experienced significant development, especially in the English NLP world. Modern approaches are mainly based on the versatile Transformer architecture proposed by Vaswani et al. in 2017, which has revolutionized the field, and was later tuned and adjusted to various needs of different tasks. Non-mainstream languages, with Czech taken as a representative, on the other hand, are a little bit behind these efforts and tend to use lighter or heuristic methods. With the new CzeGPT-2 model and abstractive summarizer, we would like to take a step forward detailing the process of training a GPT-2 generative transformer model for a new language with a comprehensive evaluation of the task of Czech summarization and pointing out the benefits of this approach. We also present an in-depth analysis of the errors in generated summaries, allowing to locate the model’s weak spots.},
