Overview

The SaketR1/uncertainty-sft model is a 2.3 billion parameter language model, derived from the Qwen/Qwen3.5-2B base model. It has been fine-tuned using the TRL library through a Supervised Fine-Tuning (SFT) procedure. This model is designed to handle a context length of up to 32,768 tokens, allowing for processing and generating longer sequences of text.

Key Capabilities

  • Text Generation: Capable of generating coherent and contextually relevant text based on user prompts.
  • Conversational AI: Fine-tuned for interactive dialogue, making it suitable for chatbot applications or question-answering systems.
  • Extended Context: Benefits from a large 32,768 token context window, enabling it to maintain context over lengthy conversations or documents.

Training Details

The model underwent Supervised Fine-Tuning (SFT) using the TRL framework. The training environment utilized specific versions of key libraries:

  • TRL: 1.5.1
  • Transformers: 5.10.0.dev0
  • Pytorch: 2.11.0+cu128
  • Datasets: 5.0.0
  • Tokenizers: 0.22.2

When to Use

This model is a good candidate for applications requiring a compact yet capable language model with strong text generation and conversational abilities, especially when dealing with longer input contexts.
