# The moment of open-sourcing the large model ChatGPT? The highly anticipated Llama 3 405B is about to be released

After much anticipation, the Llama 3 405B, originally scheduled to be released on the 23rd, is finally coming.

As the top-of-the-line model in the Llama 3 series, the 405B version boasts 405 billion parameters, making it one of the largest open-source models to date.

In the early hours of last night, a leak of the Llama 3.1-405B evaluation data by META surfaced, with some netizens speculating that a Llama 3.1-70B version might also be released simultaneously, as "leaking models in advance is a tradition at META, just like what happened with the Llama models last year."

Some analysts believe that the Llama 3 405B is not just another advancement in artificial intelligence capabilities. For open-source AI, "this could be a potential ChatGPT moment," where the most advanced AI truly democratizes and is directly handed over to developers.

## Three Predictions for the Upcoming Llama 3 405B Announcement

Analysts have predicted highlights of the upcoming Llama 3 405B announcement from the perspectives of data quality, model ecosystem, and API solutions.

**Firstly, Llama 3 405B may revolutionize the data quality of specialized models.**

For developers focusing on building specialized AI models, a long-standing challenge they face is acquiring high-quality training data. Smaller expert models (1-10 billion parameters) typically utilize distillation techniques, enhancing their training datasets with outputs from larger models. However, the use of such data from closed-source giants like OpenAI is heavily restricted, limiting commercial applications.

Enter Llama 3 405B. As an open-source giant comparable to proprietary models, it provides a new foundation for developers to create rich, unrestricted datasets. This means developers can freely use the distillation output of Llama 3 405B to train niche models, significantly accelerating innovation and deployment cycles in professional fields. The development of high-performance, fine-tuned models is expected to surge, models that are both powerful and compliant with open-source ethical standards.

**Secondly, Llama 3 405B will establish a new model ecosystem: from base models to expert ensembles**

The launch of Llama 3 405B may redefine the architecture of AI systems. The model's massive scale (405 billion parameters) may suggest a one-size-fits-all solution, but the real power lies in its integration with a hierarchical model system. This approach resonates particularly with developers using AI of different scales.

A shift towards a more dynamic model ecosystem is expected, where Llama 3 405B acts as the backbone, supported by small and medium-sized models. These systems may adopt techniques like speculative decoding, where less complex models handle most processing, only calling on the 405B model for validation and correction when necessary Not only can this maximize efficiency, but it also opens up new avenues for optimizing computing resources and response times in real-time applications, especially when running on the SambaNova RDU optimized for these tasks.

**Finally, Llama 3 405B competes with the most efficient API**

With great power comes great responsibility - for Llama 3 405B, deployment is a significant challenge. Developers and organizations need to carefully address the complexity of the model and operational requirements. There will be competition among AI cloud providers to offer the most efficient and cost-effective API solutions for deploying Llama 3 405B.

This situation provides developers with a unique opportunity to interact with different platforms and compare how various APIs handle such massive models. The winners in this field will be those who can provide APIs that not only effectively manage computational loads but also do not sacrifice model accuracy or disproportionately increase carbon footprint.

In conclusion, Llama 3 405B is not just another tool in the AI arsenal; it represents a fundamental shift towards open, scalable, and efficient AI development. Analysis suggests that whether fine-tuning niche models, building complex AI systems, or optimizing deployment strategies, the arrival of Llama 3 405B will open up new horizons for users.

## How do netizens view this?

Netizens posted in the LocalLLaMA subreddit, sharing information about the Meta Llama 3.1 with 405 billion parameters. Based on the results of several key AI benchmark tests, the performance of this AI model surpasses the current leader, OpenAI's GPT-4o, marking the first time an open-source model may have outperformed the most advanced closed-source LLM model.

As shown in the benchmark tests, Meta Llama 3.1 outperforms GPT-4o in various tests such as GSM8K, Hellaswag, boolq, MMLU-humanities, MMLU-other, MMLU-stem, and winograd. However, it lags behind GPT-4o in HumanEval and MMLU-social sciences.

Ethan Mollick, Associate Professor at the Wharton School of the University of Pennsylvania, wrote:

> If these statistics are true, then it can be said that the top Al model will be freely available to everyone starting this week.
> 
> Governments, organizations, and companies in every country around the world can use the same artificial intelligence features as others. This will be very interesting.

Some netizens have summarized several highlights of the Llama 3.1 model:

> The model was trained on publicly available 15T+ tokens, with a pre-training data cut-off date of December 2023;
> 
> Fine-tuning data includes publicly available instruction fine-tuning datasets (different from Llama 3) and 15 million synthetic samples;
> 
> The model supports multiple languages, including English, French, German, Hindi, Italian, Portuguese, Spanish, and Thai.

Some netizens have stated that this is the first time an open-source model has surpassed closed-source models such as GPT4o and Claude Sonnet 3.5, achieving SOTA on multiple benchmarks.
