Modeldle

Modeldle is a short daily quiz about the AI models people use right now. Each question shows two model cards with an "or" between them, or four choices, and asks something like which model costs less per million tokens, which can take in more text, or which came out more recently. You tap a card, and both cards flip over to show the real values.

A new deck goes live every day at 08:00 UTC and holds eight questions: two easy, four medium and two hard. Questions use only the newest model in each family and only models released in the last twelve months, from labs such as Anthropic, OpenAI, Google, Meta, xAI, DeepSeek and Alibaba's Qwen. Rankings come from LMArena, while prices, context windows, output limits and knowledge cutoffs come from models.dev and the labs' own documentation. Each figure carries an "as of" date and a link to where it came from.

Alongside the daily deck there is This week in AI, a ten-question quiz every Friday about recent releases and upgrades, and an archive where every past daily and weekly quiz can be replayed. Results are graded like trading cards, from Common up to Holo rare for a perfect score, and badges mark streaks and milestones. You can play as a guest with no account; signing in keeps one streak across browsers.

Modeldle suits people who follow AI releases, developers who pick between models for work, and anyone who wants a two-minute habit that leaves them knowing a few more real numbers. It is an independent project, not tied to any AI lab, and it showed no ads when we looked.
