Sapient Intelligence released PRAXIST Beta, an autonomous R&D system that carries experimental evidence across generations.
On the full 75-task MLE-bench: • Sapient's PRAXIST got 49 gold medals and 60 medals overall for PRAXIST using deepseek-v4-pro. • Claude Opus 4.8 reached 34 gold and 55 total
And PRAXIST is open source starting today
Instead of keeping only the best candidate, PRAXIST runs parallel Research Peers and stores findings, failures, evidence strength, and lineage in a shared research graph.
That graph lets later experiments reuse validated mechanisms, retest weak claims, and combine useful discoveries from different research branches.
Introducing PRAXIST Beta, your autonomous research team🚀 Define the objective, constraints, and what success looks like. PRAXIST discovers the path. From there...
