trustalign_qwen2.5_1.5b

This is a Qwen2.5 1.5B model trained with Trust-Align, demonstrating improved LLM trustworthiness as measured by Trust-Score. Trust-Aligned models are able to provide answers grounded in the documents provided and refuse when none of the documents can support the answer.

Usage

Here, we demonstrate how to download our model from HuggingFace and perform inference using pre-provided passages. Before proceeding, ensure you have installed all dependencies listed in requirements.txt. To run our full inference pipeline, please use our code.

Josef Bican is estimated to have scored at least 805 goals in all competitive matches, which would make him the most prolific scorer of all time according to the International Federation of Football History & Statistics (IFFHS [5]. However, it is important to note that this figure is based on the RSSSF's estimate and may not be confirmed by FIFA or other official sources [1].

Details on constructing the prompt

We use an abbreviated data sample from ASQA to demonstrate how the prompt can be constructed programmatically. First, you need to define prompt_format and doc_prompt_format. Next, define the number of documents (ndoc) and the instruction. Now, when you run format_prompt, it will return you a prompt based on the outline provided in prompt_format and doc_prompt_format.

Training details

During the Trust-Align process, our models are trained using a combination of two datasets: our instruction-following corpus with a standard next-token prediction objective and our preference dataset using Direct Preference Optimization. The training data is publicly available on Hugging Face under declare-lab/trust_data. For detailed information about the training process, please visit our official repository. The models were trained on two NVIDIA A100 GPUs (40GB each).
