The field of AI is experiencing a participatory turn (Delgado et al., 2023). From tech companies to researchers, there is growing recognition that AI design and development should not happen in isolation from the people it affects. Regardless whether AI systems are designed for mental health, education or journalism, they need input from communities who deeply understand these domains. Interdisciplinary collaboration has been assuming a more pivotal role, bringing together computer scientists, researchers, ethicists and community members to create more aligned and responsible AI systems. This shift is certainly representative of progress.

When thinking about generative AI and its disruptive impact, text generation often comes up as the most representative example of this new chapter in technological advancement. Large language models (LLMs) are rapidly transforming sectors that have at their core text generation tasks such as writing, drafting or summarisation, and the online news industry has been challenged in adapting to these new tools since GPT (generative pre-trained transformer) models became known to the mass public in late 2022.

Imagine you would like to write an essay about quantum computing, but your knowledge about quantum computing comes only from your high school textbooks. In this case, you know how to write good papers, but your knowledge is limited. Now imagine if you could access any library in the world while writing. That would make your work easier, and it’s essentially what retrieval-augmented generation (RAG) does for large language models (LLMs).
