Summary

This model is the C BrainAlign stage-2 LoRA checkpoint (best_by_retrieval) merged into the full base model Qwen/Qwen2.5-1.5B-Instruct.

The folder is saved in standard Hugging Face format so it can be uploaded directly for Open LLM Leaderboard v2 evaluation.

Model Details

  • Repository: stech2333/brainalign-qwen2.5-1.5b-C
  • Architecture: Qwen2ForCausalLM
  • Base model: Qwen/Qwen2.5-1.5B-Instruct
  • Format: merged full-weights Hugging Face Transformers checkpoint
  • Precision for leaderboard submission: bfloat16

Intended Use

This model is intended for research and evaluation of the BrainAlign stage-2 fine-tuning branch C. It is suitable for standard Hugging Face transformers loading and for leaderboard-style offline evaluation where a full model repository is required instead of a standalone LoRA adapter.

License

This merged checkpoint is distributed under apache-2.0, following the declared license metadata in this repository. Please also review the upstream base model card for any additional usage notes from Qwen/Qwen2.5-1.5B-Instruct.

Limitations

This repository documents packaging and export details for evaluation. It does not claim additional safety alignment or benchmark superiority beyond the fine-tuning performed in the BrainAlign project. Downstream behavior should be validated on the target tasks before real use.
