Pebble Bench — evaluation and benchmarking for educational AI
A benchmark for how educational AI explains, grounds and protects. Our focus: clear explanations, source grounding and learner safety.
Pebble Knowledge — curriculum-aligned knowledge corpus
Curated educational knowledge and curriculum resources, with licensing and provenance recorded per source.
Pebble Local — offline deployment reference
A reference deployment for a school-local Pebble node and the devices it serves.
Pebble Models — specialised educational models
Model cards cover purpose, supported domains, languages, evaluation, known limitations and safety.
Pebble Classroom — technology supporting educators
Built with educators, not around them.
A Pebble model card accommodates purpose, supported domains, languages, context, evaluation, known limitations, safety and data disclosure — and links to the report, repository and related research.
Safety is part of the product. Safeguarding, responsible-AI review and published model cards come before release, not after.
Education is something we build together.
