Play to learn.

Playgrounds are small, focused tools that isolate one design lever at a time. Each one produces an artifact you can download.

Diff mode

Run one prompt through two configurations side-by-side. The fastest way to feel how prompts shape outputs.

Treat style as a design token. Move dials for warmth, verbosity, energy, directness — see the prompt compose itself.

Design a character — backstory, beliefs, blind spots — and watch the model embody them.

Probe boundary design with a panel of edge cases. Tune the line between over- and under-refusal.

Rubric-based evaluation. Define what good looks like, score the model against it, watch the average move.

Multi-turn flow design. Script the user's turns, run the conversation end-to-end, watch the model hold the thread.
