Falcon-7B is a 7B parameters causal decoder-only model built by TII and trained on 1,500B tokens of RefinedWeb enhanced with curated corpora. It is made available under the Apache 2.0 license.
Paper coming soon ?.
? To get started with Falcon (inference, finetuning, quantization, etc.), we recommend reading this great blogpost fron HF !
⚠️ 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 .
? Looking for an even more powerful model? Falcon-40B is Falcon-7B's big brother!

? Falcon LLMs require PyTorch 2.0 for use with transformers !
For fast inference with Falcon, check-out Text Generation Inference ! Read more in this blogpost .
You will need at least 16GB of memory to swiftly run inference with Falcon-7B.
Research on large language models; as a foundation for further specialization and finetuning for specific usecases (e.g., summarization, text generation, chatbot, etc.)
Production use without adequate assessment of risks and mitigation; any use cases which may be considered irresponsible or harmful.
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.
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.

Falcon-7B was trained on 1,500B tokens of 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 ).
Data source | Fraction | Tokens | Sources |
---|---|---|---|
RefinedWeb-English | 79% | 1,185B | massive web crawl |
Books | 7% | 110B | |
Conversations | 6% | 85B | Reddit, StackOverflow, HackerNews |
Code | 3% | 45B | |
RefinedWeb-French | 3% | 45B | massive web crawl |
Technical | 2% | 30B | arXiv, PubMed, USPTO, etc. |
The data was tokenized with the Falcon- 7B / 40B tokenizer.
Falcon-7B was trained on 384 A100 40GB GPUs, using a 2D parallelism strategy (PP=2, DP=192) combined with ZeRO.

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 ), with the following differences:
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 |
Falcon-7B was trained on AWS SageMaker, on 384 A100 40GB GPUs in P4d instances.
SoftwareFalcon-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.)
