# 🚀 Falcon-7B |
|
|
|
**Falcon-7B is a 7B parameters causal decoder-only model built by [TII](https://www.tii.ae) and trained on 1,500B tokens of [RefinedWeb](https://huggingface.co/datasets/tiiuae/falcon-refinedweb) enhanced with curated corpora. It is made available under the Apache 2.0 license.** |
|
|
|
*Paper coming soon* 😊. |
|
|
|
## Why use Falcon-7B? |
|
|
|
* **It outperforms 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)). |
|
* **It is made available under a permissive Apache 2.0 license allowing for commercial use**, without any royalties or restrictions. |
|
|
|
⚠️ **This is a raw, pretrained model, which should be further finetuned for most usecases.** 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](https://huggingface.co/tiiuae/falcon-7b-instruct). |
|
|
|
🔥 **Looking for an even more powerful model?** [Falcon-40B](https://huggingface.co/tiiuae/falcon-40b) is Falcon-7B'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. |
|
|
|
### Model Source |
|
|
|
- **Paper:** *coming soon*. |
|
|
|
## Uses |
|
|
|
### Direct Use |
|
|
|
Research on large language models; as a foundation for further specialization and finetuning for specific usecases (e.g., summarization, text generation, chatbot, etc.) |
|
|
|
### 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 is trained on English and French data only, 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 to consider finetuning it for the specific set of tasks of interest, and for guardrails and appropriate precautions to be taken for any production use. |
|

## Training Details |
|
|
|
### Training Data |
|
|
|
Falcon-7B was trained on 1,500B tokens of [RefinedWeb](https://huggingface.co/datasets/tiiuae/falcon-refinedweb), a high-quality filtered and deduplicated web dataset which we enhanced with curated corpora. Significant components from our curated copora were inspired by The Pile ([Gao et al., 2020](https://arxiv.org/abs/2101.00027)). |
|
|
|
| **Data source** | **Fraction** | **Tokens** | **Sources** | |

| RefinedWeb-French | 3% | 45B | massive web crawl | |
|
| Technical | 2% | 30B | arXiv, PubMed, UPSTO, etc. | |
|
|
|
|
|
The data was tokenized with the Falcon-[7B](https://huggingface.co/tiiuae/falcon-7b)/[40B](https://huggingface.co/tiiuae/falcon-40b) tokenizer. |
|
|
|
### Training Procedure |
|
|
|
Falcon-7B was trained on 384 A100 40GB GPUs, using a 2D parallelism strategy (PP=2, DP=192) combined with ZeRO. |

## Technical Specifications |
|
|
|
### 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 was trained on AWS SageMaker, on 384 A100 40GB GPUs in P4d instances. |
|
|
|
#### Software |
|
|
|
Falcon-7B was trained a custom distributed training codebase, Gigatron. It uses a 3D parallelism approach combined with ZeRO and high-performance Triton kernels (FlashAttention, etc.) |
