Overview

Nemotron-Cascade-14B-Thinking is a 14 billion parameter model developed by NVIDIA, post-trained from the Qwen3-14B Base model. It leverages a unique sequential and domain-wise reinforcement learning (Cascade RL) pipeline, which includes a multi-stage Supervised Fine-Tuning (SFT) phase followed by RLHF and domain-specific RLVR stages. This model is exclusively designed for the "thinking" mode, focusing on enhancing complex reasoning abilities.

Key Capabilities

• Best-in-Class Reasoning: Achieves top performance across diverse benchmarks, including general-knowledge reasoning, mathematical reasoning, competitive programming, and software engineering.
• Advanced Code Performance: Demonstrates superior results in code-related tasks, notably outperforming DeepSeek-R1-0528 (671B) across LiveCodeBench v5, v6, and Pro benchmarks.
• Reinforcement Learning Optimization: Utilizes a sophisticated Cascade RL process that significantly boosts complex reasoning without degrading performance in earlier domains.
• Long Context Support: Recommends RoPE scaling with YaRN method, allowing context lengths up to 90K tokens for specific tasks like SWE Verified (Agentless) and 64K for others.
