Qwen2.5-32B-Instruct-CFT

Introduction

Qwen2.5-32B-Instruct-CFT is a 32B parameter model fine-tuned using our novel Critique Fine-Tuning (CFT) approach. Built upon the Qwen2.5-32B-Instruct base model, this variant is trained to critique and analyze responses rather than simply imitate them, leading to enhanced reasoning capabilities.

Key Features

• Built on the powerful Qwen2.5-32B-Instruct foundation
• Trained using Critique Fine-Tuning (CFT) methodology
• Highly efficient training with minimal data requirements
• Inherits the strong instruction-following capabilities of the base model
