RLVR lets small models close the coding gap; Python's dynamic typing hurts pretraining

mdancho84 highlights two takeaways from the 303-page code intelligence report: small models trained with RLVR (verifiable rewards) can nearly match frontier giants on reasoning-style coding tasks, and mixing languages in pretraining has limits—Python's dynamic typing creates negative transfer versus statically typed languages, while pairs like Java↔Cand JS↔TS show strong synergy.
