Nemotron-Cascade 2: Post-Training LLMs with Cascade RL and Multi-Domain On-Policy Distillation

via Arxiv 👤 Zhuolin Yang, Zihan Liu, Yang Chen et al. 📅 2026-03-19

⚡ Score: 8.1

"We introduce Nemotron-Cascade 2, an open 30B MoE model with 3B activated parameters that delivers best-in-class reasoning and strong agentic capabilities. Despite its compact size, its mathematical and coding reasoning performance approaches that of frontier open models. It is the second open-weight..."

The $\mathbf{Y}$-Combinator for LLMs: Solving Long-Context Rot with $λ$-Calculus

via Arxiv 👤 Amartya Roy, Rasul Tutunov, Xiaotong Ji et al. 📅 2026-03-20

⚡ Score: 6.7

"LLMs are increasingly used as general-purpose reasoners, but long inputs remain bottlenecked by a fixed context window. Recursive Language Models (RLMs) address this by externalising the prompt and recursively solving subproblems. Yet existing RLMs depend on an open-ended read-eval-print loop (REPL)..."
