Back when I worked on it, before AI, you have all the information from a game in an API and you just fill in the template with it. Now, I imagine they take that raw API call and just use a prompt like, "write a summary article for a game using this data" and it spits it out. And I assume the prompt is more thought out than that (or not? It is ESPN after all). I don't ever remember "retiring_players" being part of an API response, though, ;P edit: Oh and yes, the play by play recap is documented EXTREMELY well. You would be surprised. The more popular sports like Gridiron Football and Basketball would literally have player locations by the second. This data all comes from feeds like SportsRadar. They probably wouldn't pipe the fine tuned stuff like that in to a prompt, but you still have a decent summary like how many 3-pointers someone had and where they shot them from.
