Falcon-7B-Instruct is a 7B parameters causal decoder-only model built by TII based on Falcon-7B and finetuned on a mixture of chat/instruct datasets. 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 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 .
? Looking for an even more powerful model? Falcon-40B-Instruct is Falcon-7B-Instruct'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-Instruct.
Falcon-7B-Instruct has been finetuned on a mixture of instruct and chat datasets.
Production use without adequate assessment of risks and mitigation; any use cases which may be considered irresponsible or harmful.
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.
We recommend users of Falcon-7B-Instruct to develop guardrails and to take appropriate precautions for any production use.

Falcon-7B-Instruct was finetuned on a 250M tokens mixture of instruct/chat datasets.
Data source | Fraction | Tokens | Description |
---|---|---|---|
Bai ze | 65% | 164M | chat |
GPT4All | 25% | 62M | instruct |
GPTeacher | 5% | 11M | instruct |
RefinedWeb-English | 5% | 13M | massive web crawl |
The data was tokenized with the Falcon- 7B / 40B tokenizer.
Paper coming soon.
See the OpenLLM Leaderboard for early results.
Note that this model variant is not optimized for NLP benchmarks.
For more information about pretraining, see Falcon-7B .
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-Instruct was trained on AWS SageMaker, on 32 A100 40GB GPUs in P4d instances.
SoftwareFalcon-7B-Instruct was trained a custom distributed training codebase, Gigatron. It uses a 3D parallelism approach combined with ZeRO and high-performance Triton kernels (FlashAttention, etc.)
