Model Overview

prog-love/rostam-r1-stage13-1 is a 5.1 billion parameter language model that has been fine-tuned from its base model, prog-love/rostam-r1-stage13. This iteration leverages the TRL (Transformers Reinforcement Learning) library for its training process, specifically utilizing the Supervised Fine-Tuning (SFT) method.

Key Capabilities

  • Text Generation: The model is designed for general text generation tasks, capable of producing coherent and contextually relevant responses.
  • Fine-tuned Performance: As a fine-tuned version, it aims to offer improved performance over its base model for various language understanding and generation applications.
  • Extended Context Window: It supports a context length of 32768 tokens, allowing it to handle and generate longer passages of text while maintaining coherence.

Training Details

The model was trained using the SFT method, a common technique for adapting pre-trained language models to specific tasks or improving their instruction following abilities. The training environment included:

  • TRL: 1.9.2
  • Transformers: 5.15.0
  • Pytorch: 2.11.0
  • Datasets: 5.0.1
  • Tokenizers: 0.22.2

Good For

This model is suitable for developers looking for a moderately sized language model (5.1B parameters) with a substantial context window for tasks such as:

  • Generating creative content or stories.
  • Developing conversational AI agents.
  • Answering open-ended questions.
  • Prototyping text-based applications where a fine-tuned model can offer better performance than a base model.
