VeriLoop E2
VeriLoop E2 is an open 27B post-trained model built on Qwen3.8-27B for code, mathematics, and physics. It uses VeriLoop-Governed Recurrence, in which candidate states are externally checked and retained only when the protected evidence state improves without regression.
What it does
Use it for code and software engineering tasks, mathematical reasoning, and physics problems.
