Sprout is a 3-to-7 raising game where you parent a tiny mind that genuinely learns. The child is a ~110k-parameter transformer that learns from experience. Each scene presents a situation with choices; you act once — say (advise in words), show (demonstrate), or leave (let the child try alone) — the world engine resolves the outcome, and the child learns from what happened, on the spot. There are no right answers and no grades: every choice is an action, every action has an outcome, and the child learns what came of each. Meta's Muse Spark models work behind the scenes: the Director invents situations, options, and whole worlds, and the Narrator writes the prose you read — both validated by the deterministic engine, which repairs invalid outputs or falls back to templates. A full life runs 48 scenes from age 3 to 7 in the browser; researchers can watch the child's expectations, surprise, curiosity, and memories scene by scene. Honesty is enforced by tests: the learner never sees the rules table, grades, or narration — only what the child itself lived.
