Lab

Demos I built that call a model.

4 demos

  1. Give my agent a job

    Name a small web app. A model writes the code and 8 tests, and repairs the code up to 2 times when a test fails.

  2. Talk to the site

    Ask about my work out loud. A voice model answers from the text on this site and scrolls the page to what it mentions.

  3. Reorder the page

    Type 1 line about who you are. A model reorders the sections of the home page and folds the ones that matter less to you.

  4. Portfolio page from GitHub

    Enter a GitHub username. A model reads the public repos and writes a portfolio page with a link that works for 7 days.
