Meta Llama 3
We are unlocking the power of large language models. Our latest version of Llama is now accessible to individuals, creators, researchers, and businesses of all sizes so that they can experiment, innovate, and scale their ideas responsibly.
This release includes model weights and starting code for pre-trained and instruction tuned Llama 3 language models — including sizes of 8B to 70B parameters.
This repository is intended as a minimal example to load Llama 3 models and run inference. For more detailed examples, see llama-recipes.
## Download
In order to download the model weights and tokenizer, please visit the Meta Llama website and accept our License.
Once your request is approved, you will receive a signed URL over email. Then run the download.sh script, passing the URL provided when prompted to start the download.
Pre-requisites: Make sure you have wget and md5sum installed. Then run the script: ./download.sh.
Keep in mind that the links expire after 24 hours and a certain amount of downloads. If you start seeing errors such as 403: Forbidden, you can always re-request a link.
### Access to Hugging Face
We are also providing downloads on Hugging Face.
## Quick Start
You can follow the steps below to quickly get up and running with Llama 3 models. These steps will let you run quick inference locally. For more examples, see the Llama recipes repository.
1. In a conda env with PyTorch / CUDA available clone and download this repository.
2. In the top-level directory run:
bash pip install -e .
3. Visit the Meta Llama website and register to download the model/s.
4. Once registered, you will get an email with a URL to download the models. You will need this URL when you run the download.sh script.
5. Once you get the email, navigate to your downloaded llama repository and run the download.sh script.
- Make sure to grant execution permissions to the download.sh script
- During this process, you will be prompted to enter the URL from the email.
- Do not use the "Copy Link" option but rather make sure to manually copy the link from the email.
6. Once the model/s you want have been downloaded, you can run the model locally using the command below:
bash torchrun --nproc_per_node 1 example_chat_completion.py \ --ckpt_dir llama-3-8b-prerelease-instruct/ \ --tokenizer_path tokenizer.model \ --max_seq_len 512 --max_batch_size 6
Note
- Replace llama-3-8b-prerelease-instruct/ with the path to your checkpoint directory and tokenizer.model with the path to your tokenizer model.
- The –nproc_per_node should be set to the MP value for the model you are using.
- Adjust the max_seq_len and max_batch_size parameters as needed.
- This example runs the example_chat_completion.py found in this repository but you can change that to a different .py file.
## Inference
Different models require different model-parallel (MP) values:
| Model | MP |
|--------|----|
| 8B | 1 |
| 70B | 8 |
All models support sequence length up to 8192 tokens, but we pre-allocate the cache according to max_seq_len and max_batch_size values. So set those according to your hardware.
### Pretrained Models
These models are not finetuned for chat or Q&A. They should be prompted so that the expected answer is the natural continuation of the prompt.
See example_text_completion.py for some examples. To illustrate, see the command below to run it with the llama-2-7b model (nproc_per_node needs to be set to the MP value):
torchrun --nproc_per_node 1 example_text_completion.py \ --ckpt_dir llama-3-8b-prerelease/ \ --tokenizer_path tokenizer.model \ --max_seq_len 128 --max_batch_size 4
### Instruction-tuned Models
The fine-tuned models were trained for dialogue applications. To get the expected features and performance for them, a specific formatting defined in chat_completion
needs to be followed, including the INST and <<SYS>> tags, BOS and EOS tokens, and the whitespaces and breaklines in between (we recommend calling strip() on inputs to avoid double-spaces).
You can also deploy additional classifiers for filtering out inputs and outputs that are deemed unsafe. See the llama-recipes repo for an example of how to add a safety checker to the inputs and outputs of your inference code.
Examples using llama-2-7b-chat:
torchrun --nproc_per_node 1 example_chat_completion.py \ --ckpt_dir llama-3-8b-prerelease-instruct/ \ --tokenizer_path tokenizer.model \ --max_seq_len 512 --max_batch_size 6
Llama 3 is a new technology that carries potential risks with use. Testing conducted to date has not — and could not — cover all scenarios.
In order to help developers address these risks, we have created the Responsible Use Guide.
