The Most Powerful Open Source Large Language Model to Date

Introduction

LLaMA is a large language model released by Meta AI in February 2023. As the first model in this series, LLaMA is a pure base language model designed to provide an open and efficient platform for general language understanding and generation. There are four versions available: 7B, 13B, 33B, and 65B (65 billion).

Regarding the training set, all sources are public datasets with no custom datasets, ensuring its operation is compatible with open source and reproducible. The entire training dataset contains approximately 1.4 trillion tokens after tokenization. Among them, LLaMA-65B and LLaMA-33B were trained on 1.4 trillion tokens, while the smallest model, LLaMA-7B, was trained on 1 trillion tokens.

As for model performance, LLaMA performs exceptionally well: the LLaMA model with 13 billion parameters can outperform GPT-3 (which has 175 billion parameters) on “most benchmarks” and can run on a single V100 GPU; the largest 65 billion parameter LLaMA model can rival Google’s Chinchilla-70B and PaLM-540B. While other powerful large language models are typically accessible only through limited APIs, Meta has released the model weights of LLaMA under a non-commercial license for researchers to reference and use.

The largest LLaMA 3 model was trained on a custom-built cluster of 24,000 GPUs, utilizing a combination of data parallelism, model parallelism, and pipeline parallelism techniques. Meta’s advanced training stack automates error detection, processing, and maintenance, maximizing GPU uptime, resulting in training efficiency that is about three times better than LLaMA 2.

Expectations for LLaMA 3

LLaMA 3 is the latest iteration of the LLaMA series, showcasing significant technological advancements and strategic significance:

Release Timeline: LLaMA 3 was released on April 18, 2024, just nine months after the release of LLaMA 2, indicating that Meta AI has rapidly advanced technology research and development in a short time.

Model Scale and Performance:

Parameter Count: LLaMA 3 offers versions of varying scales, including the smallest version with 8 billion parameters and the largest planned version with 40.5 billion parameters. Even the smallest version’s performance is on par with LLaMA 2’s largest version (70 billion parameters), demonstrating LLaMA 3’s improvement in model efficiency.
Performance Comparison: The performance of LLaMA 3 is described as approaching GPT-4, suggesting that it may be comparable to or even surpass OpenAI’s flagship model in certain tasks, reflecting its strong competitiveness in language understanding and generation.

Training Data and Efficiency:

Data Scale: LLaMA 3 is pre-trained on over 15 trillion tokens of public data, seven times more than LLaMA 2, reflecting Meta AI’s emphasis on large-scale data-driven model performance improvement.
Training Efficiency: The training efficiency of LLaMA 3 has tripled compared to LLaMA 2, which may be attributed to algorithm optimization, hardware acceleration, or advancements in distributed training strategies, allowing for more training iterations or handling larger data volumes in the same time frame.

Integration and Application:

Virtual Assistants: LLaMA 3 will be integrated into Meta’s virtual assistant services, making it one of the most advanced AI applications available for free on platforms like Facebook, Instagram, WhatsApp, and Messenger, enhancing the intelligent interaction experience on these social platforms.

Cloud Service Support: Amazon Web Services (AWS) official blog provides detailed guidelines for using LLaMA 3 in SageMaker Studio, indicating that the model has support from mainstream cloud service providers, facilitating convenient deployment and utilization for developers and researchers.

Through LLaMA 3, our goal is to create a top-tier open-source model that can compete with the best proprietary models on the market. We aim to enhance the practicality of LLaMA 3 in response to developer feedback and continue to lead the industry standards for responsible use and deployment of large language models. We uphold the spirit of open source, advocating for “early release, frequent updates,” allowing the community to use these advanced tools while the model is still in development. The text-based models released today are preliminary results of the LLaMA 3 series. We plan to enable LLaMA 3 to support multilingual and multimodal interactions in the near future, providing longer processing contexts and continuously optimizing performance in core technologies such as reasoning and programming.

Application Scenarios
