GPT4oMini.app

Treat GPT4oMini.app as a doorway, not a workshop. Its strongest quality is the absence of friction: you open the page and ChatGPT-4o Mini answers, with no account to create and nothing to install. For a librarian who has been told to 'look into AI' and has 20 minutes between reference desk shifts, that is exactly the right shape of tool. It also fits the stated mission of the Data Science in Libraries project, which is explicitly about mid-career librarians learning through continuing education and administrators needing frameworks for data-driven decisions — both of which start with a plain-language question. The IMLS grant (RE-43-16-0149-16) gives the tool a defined audience and a reason to exist beyond novelty. The constraints are just as clear. Input and output are text only. There is no file upload, so you cannot hand it a spreadsheet of circulation counts or a CSV export and ask it to look for patterns. There is no chat history and no export, which means a good explanation you get on Tuesday is gone by Friday unless you copy it out yourself. There is no API or SDK, so nothing you learn here transfers into a script. There is no browser extension and no mobile app; it is a page you open in a browser. There are no custom instructions or system prompt, so you cannot tell it to answer as a cataloguing specialist or to keep responses short. And because the project runs on grant funding rather than customer revenue, its availability tracks that project rather than a paying user base — a real consideration if you plan to build a training curriculum around it. Where it fits: one-off explanations, terminology lookups, brainstorming during a workshop, live demos of what a chat interface is. Where it does not: anything involving patron data, anything requiring an audit trail, anything you would need to reproduce next semester.
