THaLLE: Text Hyperlocally Augmented Large Language Extension

❗NOTICE❗: KBTG-Labs/THaLLE-0.1-7B-fa is a WIP model checkpoint distributed for reproducing results in our Technical Report.

Training details

This model is a Qwen2-7B-Instruct fine-tuned on our Internal CFA Mock Exam 2009-2019 containing 9,426 Questions using LoRA.

Vocab Config Patching

Prior to training, we patched Qwen/Qwen2-7B-Instruct's tokenizer_config.json bos_token field from null to the start token "<|im_start|>".

{
    ...
    "bos_token": "<|im_start|>"
    ...
}

Results

For more details see our Technical Report.

[*] Flare CFA is "ChanceFocus/flare-cfa"

Usage

Requirements

Since KBTG-Labs/THaLLE-0.1-7B-fa is a fine-tuned of Qwen2-7B-Instruct you will need to install transformers>=4.37.0.
