# 42dot_LLM-SFT-1.3B

**42dot LLM-SFT** is a large language model (LLM) developed by [**42dot**](https://42dot.ai/) which is trained to follow natural language instructions.
42dot LLM-SFT is a part of **42dot LLM**, and derived from **42dot LLM-PLM** by supervised fine-tuning (SFT). This repository contains a 1.3B-parameter version.

## Model Description

### Hyperparameters
As same as 42dot LLM-PLM, the model is built upon a Transformer decoder architecture similar to the [LLaMA 2](https://ai.meta.com/research/publications/llama-2-open-foundation-and-fine-tuned-chat-models/) and its hyperparameters are listed below.

| Params | Layers | Attention heads | Hidden size | FFN size | Max. length\* |
| -- | -- | -- | -- | -- | -- |
| 1.3B | 24 | 32 | 2,048 | 5,632 | 4,096 |

(\* unit: tokens)
### Supervised Fine-tuning

Fine-tuning took about 112 GPU hours (in NVIDIA A100). For the training dataset, we manually constructed  (question or insturuction) and response pairs, which can either be single- or multi-turn. 

### Evaluation
Inspired by recent attempts like [Vicuna](https://lmsys.org/blog/2023-03-30-vicuna/#how-good-is-vicuna), we evaluate 42dot LLM-SFT with other proprietary/open-sourced chatbots using GPT-4 for assessing various aspects of responses. The evaluation dataset consists of 121 prompts over 10 categories. The sample of the evaluation dataset and prompt template can be downloaded from our [GitHub repo](https://github.com/42dot/42dot_LLM).

- Baselines:
  - [ChatGPT](https://chat.openai.com/) using GPT-3.5-turbo and GPT-4
  - [Bard](https://bard.google.com/)
  - [KORani-v2-13B](https://huggingface.co./KRAFTON/KORani-v1-13B)

## Limitations and Ethical Considerations
42dot LLM-SFT shares a number of well-known limitations of other LLMs. For example, it may generate false and misinformative content since 42dot LLM-SFT is also subject to [hallucination](https://en.wikipedia.org/wiki/Hallucination_(artificial_intelligence)). In addition, 42dot LLM-SFT may generate toxic, harmful, and biased content due to the use of web-available training data in the pre-training phase. We strongly suggest that 42dot LLM-SFT users should be aware of those limitations and take necessary steps to mitigate those issues.
