The Llama 3.1 Community License supports these varied use cases.

How to use

This repository includes two versions of the Meta-Llama-3.1–70B, one compatible with transformers and the other with the original Llama codebase.

Use with transformers

Beginning with transformers >= 4.43.0 onward, you can perform conversational inference using the Transformers pipeline abstraction or by utilizing the Auto classes with the generate() function.

Be sure to upgrade your transformers installation by running pip install --upgrade transformers.

import transformers
import torch

model_id = "meta-llama/Meta-Llama-3.1-70B"

pipeline = transformers.pipeline(
pipeline("Hey how are you doing today?")

Llama 3.1’s training dataset

The Llama 3.1 pre-training dataset was a carefully curated, well-balanced mixture of various general domains, meticulously processed to ensure high-quality and diverse training inputs.

Pre Training Data

The dataset construction involves four main stages:

Quality Filtering: Non-English and low-quality captions are removed using heuristic measures like CLIP scores.
Perceptual Deduplication: An internal SSCD copy-detection model deduplicates images on a large scale, retaining one image-text pair per duplicate group.
Resampling: To ensure diversity, n-grams are created from high-quality text sources, and data is resampled based on their frequencies.
Optical Character Recognition: Text within images is extracted using a proprietary OCR pipeline and combined with captions.

To enhance document understanding, the dataset also includes:

Document Transcription: Document pages are rendered as images with paired text.
Content Safety: Techniques like perceptual hashing are used to eliminate unsafe content such as CSAM.
The dataset is refined to approximately 350 million image-caption pairs and enriched with an additional 150 million examples from various sources, including visual grounding, screenshot parsing, question-answer pairs, synthetic captions, and synthetically generated structured images.

Post Training Data

SFT Data:

For images: Academic datasets are transformed into Q&A pairs through templates and LLM rewrites. Human annotators create diverse dialogues from multimodal data to enhance model-generated content.
For synthetic data: Text representations of images are used with text-input LLMs to create question-answer pairs for corresponding images. This process involves converting Q&A texts and table data into synthetic images using captions and OCR extractions to generate conversational data.
For videos: Academic datasets with annotations are turned into textual instructions and target responses for questions. Humans annotate videos with complex questions and answers requiring more than a single frame for context.

Preference Data:

The dataset includes model outputs rated “chosen” or “rejected” on a 7-point scale, with human annotations for preferences and corrections. Synthetic preference pairs are created using text-only LLMs to introduce errors into the fine-tuning dataset, generating negative samples through rejection sampling from unselected high-quality responses.

Applying DPO to Llama 3.1

Meta implemented Direct Preference Optimization (DPO) as a crucial part of the post-training process for Llama 3.1 to better align the model with human preferences. Here’s a breakdown of how this process was carried out:

Initial Setup:

The process starts by training on human-annotated preference data, building on the most successful models from previous alignment rounds.
The main objective is to ensure that the training data closely matches the distribution of the policy model being optimized in each cycle, which helps progressively enhance the model’s performance.
Preference Data Collection:

Preference data is gathered from human annotators who evaluate multiple model-generated responses for each prompt. These evaluations are based on the responses’ quality and preference, with clear rankings such as edited > chosen > rejected.
This data encompasses responses sorted into various preference levels (significantly better, better, slightly better, or marginally better) and occasionally includes edited responses to further refine the chosen response.

Experiment of Llama 3.1

Llama 3.1’s Vision Experiments evaluate its image and video recognition performance. Speech Experiments showcase its speech recognition capabilities. The results highlight the model’s resilience and potential applications in AI.

Vision Experiments of Llama 3.1

Image Recognition Results

The Llama 3-V 405B model surpasses GPT-4V in all benchmarks, though it slightly trails behind Gemini 1.5 Pro and Claude 3.5 Sonnet.
It shows particular strength in document understanding tasks.

Video Recognition Results

Llama 3 excels in video recognition, particularly with the 8B and 70B parameter models being assessed.
It performs exceptionally well on the PerceptionTest, indicating a robust capacity for complex temporal reasoning.
In long-form activity understanding tasks, such as ActivityNet-QA, Llama 3 delivers strong results even though it processes only up to 64 frames. This means that for a three-minute video, the model processes just one frame every three seconds.

Speech Experiments of Llama 3.1

A real-time streaming text-to-speech (TTS) system is now part of Llama 3, creating speech waveforms while decoding. This TTS system uses Llama 3 embeddings for improved latency, accuracy, and naturalness during inference.

What is annealing, and how does it work?

Training large language models like Llama 3.1 involves ‘annealing,’ which fine-tunes the model for better task performance. The term is borrowed from metallurgy, where annealing toughens materials by heating and slowly cooling them.

The annealing process for Llama 3.1 involves several key components:

Gradual Reduction of Learning Rate: The learning rate is systematically decreased to zero, stabilizing parameters and enhancing generalization by minimizing overfitting.
Upsampling High-Quality Data: The training data mix is adjusted to prioritize high-quality sources, improving model performance and accuracy.
Polyak Averaging: This technique averages parameters from various checkpoints during annealing to create a stable pre-trained model.

Overall, the annealing process ensures smooth convergence, enhances stability through smaller parameter updates, and results in a robust and precise model well-equipped for generalization to new data.
