Frequently asked questions about bAIseball
What data sources does bAIseball use?
The tool combines Retrosheet Game Logs (1871–present), Retrosheet player-per-game stats (1898–present), the Lahman Baseball Database, and MLB Stats API for live/current-season data updated automatically throughout the season.
Is bAIseball a nonprofit?
No, it is not a nonprofit. The creator chose the .org domain because baiseball.com was already taken.
What is the difference between current season and historical data?
During an active season, numbers are season-to-date from MLB Stats API. Once Retrosheet and Lahman publish their official update for that season, the site switches to those canonical numbers.
