🚀 Falcon-7b-QueAns

Falcon-7b-QueAns is a chatbot-like model for Question and Answering. It was built by fine-tuning Falcon-7B on the SQuAD dataset. This repo only includes the QLoRA adapters from fine-tuning with 🤗's peft package.

Model Summary

• Model Type: Causal decoder-only
• Language(s): English
• Base Model: Falcon-7B (License: Apache 2.0)
• Dataset: SQuAD (License: cc-by-4.0)
• License(s): Apache 2.0 inherited from "Base Model" and "Dataset"

Why use Falcon-7B?

• It outperforms comparable open-source models (e.g., MPT-7B, StableLM, RedPajama etc.), thanks to being trained on 1,500B tokens of RefinedWeb enhanced with curated corpora. See the OpenLLM Leaderboard.
• It features an architecture optimized for inference, with FlashAttention (Dao et al., 2022) and multiquery (Shazeer et al., 2019).
• It is made available under a permissive Apache 2.0 license allowing for commercial use, without any royalties or restrictions.

⚠️ This is a finetuned version for specifically question and answering. If you are looking for a version better suited to taking generic instructions in a chat format, we recommend taking a look at Falcon-7B-Instruct.

🔥 Looking for an even more powerful model? Falcon-40B is Falcon-7B's big brother!

Model Details

The model was fine-tuned in 4-bit precision using 🤗 peft adapters, transformers, and bitsandbytes. Training relied on a method called "Low Rank Adapters" (LoRA), specifically the QLoRA variant. The run took approximately 4 hours and was executed on a workstation with a single T4 NVIDIA GPU with 15 GB of available memory. See attached [Colab Notebook] used to train the model.
