Overview

This model, alirezaaminzadeh/minizinc-codegen-coder, is a specialized 1.5 billion parameter instruction-tuned language model. It is a fine-tuned version of the Qwen/Qwen2.5-Coder-1.5B-Instruct base model, developed by alirezaaminzadeh. The fine-tuning process utilized the TRL library, indicating a focus on reinforcement learning from human feedback or similar techniques to enhance its performance.

Key Capabilities

  • Code Generation: Optimized for generating code, building upon the capabilities of its Qwen2.5-Coder base.
  • Instruction Following: Designed to respond to instructions effectively due to its instruction-tuned nature.
  • Large Context Window: Features a substantial context length of 32768 tokens, allowing it to process and generate longer code snippets or complex programming logic.

Training Details

The model was trained using Supervised Fine-Tuning (SFT) methods. The training leveraged specific versions of key frameworks:

  • TRL: 1.9.2
  • Transformers: 5.14.1
  • Pytorch: 2.13.0
  • Datasets: 5.0.1
  • Tokenizers: 0.22.2

Good For

  • Developers seeking a specialized model for code generation tasks.
  • Applications requiring a model with strong instruction-following capabilities in a coding context.
  • Scenarios where a large context window is beneficial for handling extensive codebases or complex programming problems.
