Raising Sprout: what deterministic reasoning looks like in practice
A progress report on a symbolic reasoner being developed as an observable educational experiment.
The work
Sprout is a deterministic, zero-GPU symbolic reasoner. It is being developed in public as an engineering and educational experiment, not presented as a finished general intelligence system. That distinction matters. The point is to make progress measurable and failure visible.
What the evidence says
As of 29 July 2026, the live system held 93,429 facts and had recorded zero hallucinations across 251 adversarial tests. Its current capability is estimated at an early-to-mid Grade 2 level. Those numbers are a bounded system observation, not a claim that Sprout is broadly intelligent.
Why FounderHub is doing it
Most AI development hides uncertainty behind fluent output. Sprout explores the opposite route: explicit knowledge, deterministic behaviour and testable progress. The research informs FounderHub's wider work on governed reasoning, evidence-led learning and dependable AI operations.
