# ✨ Falcon-7B-Instruct |
|
|
|
**Falcon-7B-Instruct is a 7B parameters causal decoder-only model built by [TII](https://www.tii.ae) based on [Falcon-7B](https://huggingface.co/tiiuae/falcon-7b) and finetuned on a mixture of chat/instruct datasets. It is made available under the Apache 2.0 license.** |
|
|
|
*Paper coming soon 😊.* |
|
|
|
## Why use Falcon-7B-Instruct? |
|
|
|
* **You are looking for a ready-to-use chat/instruct model based on [Falcon-7B](https://huggingface.co/tiiuae/falcon-7b).** |
|
* **Falcon-7B is a strong base model, outperforming comparable open-source models** (e.g., [MPT-7B](https://huggingface.co/mosaicml/mpt-7b), [StableLM](https://github.com/Stability-AI/StableLM), [RedPajama](https://huggingface.co/togethercomputer/RedPajama-INCITE-Base-7B-v0.1) etc.), thanks to being trained on 1,500B tokens of [RefinedWeb](https://huggingface.co/datasets/tiiuae/falcon-refinedweb) enhanced with curated corpora. 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-7B](https://huggingface.co/tiiuae/falcon-7b). |
|
|
|
🔥 **Looking for an even more powerful model?** [Falcon-40B-Instruct](https://huggingface.co/tiiuae/falcon-40b-instruct) is Falcon-7B-Instruct's big 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-7B](https://huggingface.co/tiiuae/falcon-7b). |
|
|
|
### Model Source |

- **Paper:** *coming soon*. |
|
|
|
## Uses |
|
|
|
### Direct Use |
|
|
|
Falcon-7B-Instruct has been finetuned on a mixture of instruct and chat datasets. |
|
|
|
### 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-7B-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-7B-Instruct to develop guardrails and to take appropriate precautions for any production use. |
|

## Training Details |
|
|
|
### Training Data |
|
|
|
Falcon-7B-Instruct was finetuned on a 250M tokens mixture of instruct/chat datasets. |
|
|
|
| **Data source** | **Fraction** | **Tokens** | **Description** | |
|
|--------------------|--------------|------------|-----------------------------------| |
|
| [Bai ze](https://github.com/project-baize/baize-chatbot) | 65% | 164M | chat | |
|
| [GPT4All](https://github.com/nomic-ai/gpt4all) | 25% | 62M | instruct | |
|
| [GPTeacher](https://github.com/teknium1/GPTeacher) | 5% | 11M | instruct | |
|
| [RefinedWeb-English](https://huggingface.co/datasets/tiiuae/falcon-refinedweb) | 5% | 13M | massive web crawl | |
|
|
|
|
|

|
|

|
|
|
### Model Architecture and Objective |
|
|
|
Falcon-7B 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. |
|
|
|
| **Hyperparameter** | **Value** | **Comment** | |
|
|--------------------|-----------|----------------------------------------| |
|
| Layers | 32 | | |
|
| `d_model` | 4544 | Increased to compensate for multiquery | |
|
| `head_dim` | 64 | Reduced to optimise for FlashAttention | |
|
| Vocabulary | 65024 | | |
|
| Sequence length | 2048 | | |
|
|
|
### Compute Infrastructure |
|
|
|
#### Hardware |
|
|

Falcon-7B-Instruct was trained on AWS SageMaker, on 32 A100 40GB GPUs in P4d instances. |
|
|
|
