Model Overview

SaketR1/uncertainty-sft-2 is a 2.3 billion parameter language model, fine-tuned from the Qwen/Qwen3.5-2B architecture. The fine-tuning process utilized the TRL library, a framework for Transformer Reinforcement Learning, specifically employing Supervised Fine-Tuning (SFT).

Key Capabilities

  • General Text Generation: Capable of generating human-like text based on given prompts.
  • Instruction Following: Fine-tuned to understand and respond to user instructions.
  • Moderate Context Handling: Supports a context length of 32,768 tokens, allowing for processing and generating longer sequences of text.

Training Details

The model was trained using the SFT method within the TRL framework. The development environment included TRL 1.6.0, Transformers 5.13.0.dev0, Pytorch 2.11.0+cu128, Datasets 5.0.0, and Tokenizers 0.22.2.

Use Cases

This model is suitable for various applications requiring text generation, such as chatbots, content creation, summarization, and question-answering, particularly where a balance between model size and context handling is desired.
