Promptfu
Promptfoo is an open-source tool for evaluating AI prompts. Ever wonder how many tokens a prompt actually uses? Are you curious about the cost? Want to pit Claude head-to-head against Codex or open-source models running on Ollama to see who wins?
This is a hands-on session. You'll download and use Promptfoo yourself, with guided walkthroughs along the way. Bring your laptop.
Improving is providing pizza at 6:00 and the presentation will begin at 6:30.
