Nemotron-Cascade-14B-Thinking (Modified Chat Template)
This is a modified version of nvidia/Nemotron-Cascade-14B-Thinking with a fixed chat template for RL training compatibility.
Changes
The original Nemotron chat template strips <think> sections from messages when processing inputs. This violates the increasing context requirement for multi-turn RL training (see verifiers documentation).
This version uses a simplified chat template (based on willcb/Qwen3-14B) that preserves thinking tokens in the conversation history, making it suitable for RL training with tools like verifiers.
