(founder of castform here) - we didn't get to dive too deep into the dataset we were using for the retrieval in the blogpost for brevity, but we did link the training run (which shows the dataset) here: https://app.castform.com/train/a7a898f6-d802-4908-b044-acb81...

the page shows the exact trace of all the models we are comparing against and the aggregate scores

we generated the question & answer pair from gitlab product handbook (https://handbook.gitlab.com/) since the point is to show that you can generate training questions from raw data corpus (something a company already has today)
