Model Overview

The davidheineman/opd-teacher-Q2.5I-Disinfection-step149 is a specialized 1.5 billion parameter instruction-tuned model based on the Qwen2.5 architecture. Developed by davidheineman, this model functions as an on-policy distillation (OPD) teacher, specifically trained within a reinforcement learning environment.

Key Characteristics

  • Base Model: Utilizes the Qwen/Qwen2.5-1.5B-Instruct as its foundation.
  • Training Method: Trained using Reinforcement Learning from Value Equivalents (RLVE) with the GRPO algorithm.
  • Environment Specificity: Fine-tuned exclusively on the Disinfection environment at difficulty 0.
  • Training Duration: Underwent 150 updates, with step149 representing the final checkpoint.
  • Context Length: Supports a substantial context window of 32768 tokens.

Intended Use

This model is designed for experimental purposes, particularly within the context of a 32-environment on-policy distillation experiment. Its specialized training makes it suitable for research and development in reinforcement learning and model distillation within defined environments, rather than general conversational or creative tasks.
