# ✨ Falcon-40B-Instruct |
|
|
|
**Falcon-40B-Instruct is a 40B parameters causal decoder-only model built by [TII](https://www.tii.ae) based on [Falcon-40B](https://huggingface.co/tiiuae/falcon-40b) and finetuned on a mixture of [Baize](https://github.com/project-baize/baize-chatbot). It is made available under the Apache 2.0 license.** |
|
|
|
*Paper coming soon 😊.* |
|
|
|
## Why use Falcon-40B-Instruct? |
|
|
|
* **You are looking for a ready-to-use chat/instruct model based on [Falcon-40B](https://huggingface.co/tiiuae/falcon-40b).** |
|
* **Falcon-40B is the best open-source model available.** It outperforms [LLaMA](https://github.com/facebookresearch/llama), [StableLM](https://github.com/Stability-AI/StableLM), [RedPajama](https://huggingface.co/togethercomputer/RedPajama-INCITE-Base-7B-v0.1), [MPT](https://huggingface.co/mosaicml/mpt-7b), etc. See the [OpenLLM Leaderboard](https://huggingface.co/spaces/HuggingFaceH4/open_llm_leaderboard). |
|
* **It features an architecture optimized for inference**, with FlashAttention ([Dao et al., 2022](https://arxiv.org/abs/2205.14135)) and multiquery ([Shazeer et al., 2019](https://arxiv.org/abs/1911.02150)). |
|
|
|
💬 **This is an instruct model, which may not be ideal for further finetuning.** If you are interested in building your own instruct/chat model, we recommend starting from [Falcon-40B](https://huggingface.co/tiiuae/falcon-40b). |
|
|
|
💸 **Looking for a smaller, less expensive model?** [Falcon-7B-Instruct](https://huggingface.co/tiiuae/falcon-7b-instruct) is Falcon-40B-Instruct's little brother! |

|
## Model Details |
|
|
|
### Model Description |
|
|
|
- **Developed by:** [https://www.tii.ae](https://www.tii.ae); |
|
- **Model type:** Causal decoder-only; |
|
- **Language(s) (NLP):** English and French; |
|
- **License:** Apache 2.0; |
|
- **Finetuned from model:** [Falcon-40B](https://huggingface.co/tiiuae/falcon-40b). |
|
|
|
### Model Source |
|
|
|
- **Paper:** *coming soon*. |
|
|
|
## Uses |
|
|
|
### Direct Use |
|
|
|
Falcon-40B-Instruct has been finetuned on a chat dataset. |
|
|
|
### Out-of-Scope Use |
|
|
|
Production use without adequate assessment of risks and mitigation; any use cases which may be considered irresponsible or harmful. |
|
|
|
## Bias, Risks, and Limitations |
|
|
|
Falcon-40B-Instruct is mostly trained on English data, and will not generalize appropriately to other languages. Furthermore, as it is trained on a large-scale corpora representative of the web, it will carry the stereotypes and biases commonly encountered online. |
|
|
|
### Recommendations |
|
|
|
We recommend users of Falcon-40B-Instruct to develop guardrails and to take appropriate precautions for any production use. |
|
|
|

## Training Details |
|
|
|
### Training Data |
|
|
|
Falcon-40B-Instruct was finetuned on a 150M tokens from [Bai ze](https://github.com/project-baize/baize-chatbot) mixed with 5% of [RefinedWeb](https://huggingface.co/datasets/tiiuae/falcon-refinedweb) data. |
|
|
|
|
|
The data was tokenized with the Falcon-[7B](https://huggingface.co/tiiuae/falcon-7b)/[40B](https://huggingface.co/tiiuae/falcon-40b) tokenizer. |
|
|
|
|
|
## Evaluation |
|
|
|
*Paper coming soon.* |
|
|
|
See the [OpenLLM Leaderboard](https://huggingface.co/spaces/HuggingFaceH4/open_llm_leaderboard) for early results. |

|
## Technical Specifications |
|
|
|

|
|
|
### Model Architecture and Objective |
|
|
|
Falcon-40B is a causal decoder-only model trained on a causal language modeling task (i.e., predict the next token). |
|
|
|
The architecture is broadly adapted from the GPT-3 paper ([Brown et al., 2020](https://arxiv.org/abs/2005.14165)), with the following differences: |
|
|
|
* **Positionnal embeddings:** rotary ([Su et al., 2021](https://arxiv.org/abs/2104.09864)); |
|
* **Attention:** multiquery ([Shazeer et al., 2019](https://arxiv.org/abs/1911.02150)) and FlashAttention ([Dao et al., 2022](https://arxiv.org/abs/2205.14135)); |
|
* **Decoder-block:** parallel attention/MLP with a single layer norm. |
|
|
|
For multiquery, we are using an internal variant which uses independent key and values per tensor parallel degree. |

|
|
|
