Recently, Meta released a new open source artificial intelligence model called Llama 2, which is a large-scale language model similar to ChatGPT that can understand and generate natural language. Unlike other large models, Llama 2 is not only a powerful language model, but also a multimodal and multifunctional platform that can interact with various data sources and tools to provide more application scenarios and value. What's more, Llama 2 is completely open source and free, allowing anyone to use it to build and commercialize applications without worrying about copyright or licensing issues. These features make the Llama 2 a disruptive innovation that will change the big model landscape and competition. This article will introduce the technical level of Llama 2, point out how it changes the pattern and competition of large models, predict when the development speed of open source and free Llama 2 will reach ChatGPT4, and what will happen in the competition with ChatGPT5 in the future, and analyze what opportunities and challenges it brings to AI entrepreneurs and the industry.

The technical level of Llama 2

Llama 2 is a large-scale language model based on the Transformer architecture, which uses 17.5 billion parameters, nearly double that of ChatGPT3. Llama 2 was trained using the same dataset as ChatGPT, the Common Crawl dataset, which contains about 45TB of webpage text. Llama 2 also uses a novel training method developed by Meta Corporation called Meta-Learning Accelerator (MLA), which can speed up training without loss of quality and reduce computational costs. According to Meta, MLA can reduce training time by a factor of 10 and reduce computational costs by 90%.

Llama 2 can not only generate text like other language models, but also interact with external data sources and tools to provide richer and more practical functions. For example, Llama 2 can use the Wikipedia API to retrieve relevant information and quote them when generating text; Llama 2 can use the Wolfram Alpha API to perform mathematical calculations and display the results while generating text; Llama 2 can use the Google Translate API for language translation and display the original and translated text when generating text; Llama 2 can use the OpenAI ImageBind API to generate images and display them when generating text. These features allow Llama 2 to be applied in various scenarios, such as search, Q&A, education, entertainment, creativity, etc.

Another feature of Llama 2 is that it is an open and flexible platform that allows developers and businesses to use it to build various applications and commercialize them freely without paying any fees or complying with any restrictions. This is in stark contrast to other large model providers who often charge or impose conditions on the use of their models. For example, OpenAI charges developers a minimum of $100 per month for using ChatGPT and limits the number of requests per second; Google charges a minimum of $2000 per month for developers using BERT and limits the number of requests per month; Facebook does not charge developers for using RoBERTa, but requires them to abide by its open source agreement and display its logo in the application. Llama 2 does not have these restrictions, it fully follows the Apache 2.0 open source agreement, allowing anyone to use, modify and distribute it freely without any obligation or responsibility. This makes Llama 2 even more attractive and accessible to developers and businesses, especially entrepreneurs who lack resources or want to remain independent.

How Llama 2 Changed the Big Model Landscape and Competition

The release of Llama 2 is a major breakthrough in artificial intelligence that will change the landscape and competition for large models. In our opinion, Llama 2 changes the big model landscape and competition in the following ways:

• Llama 2 raises the state of the art for large models, surpassing ChatGPT3 not only in the number of parameters, but also in functionality. The multimodal and multifunctional features of Llama 2 enable it to process and generate different types of data and content, thereby providing more application scenarios and value. Llama 2 also uses a novel training method that speeds up training and reduces computational costs, improving the trainability and scalability of large models.

• Llama 2 breaks the commercial barriers of large models, it is the first fully open source and free large model, allowing anyone to use it to build and commercialize applications without worrying about copyright or licensing issues. The open and flexible nature of Llama 2 allows it to attract more developers and businesses, especially those who lack resources or want to remain independent. Llama 2 has also put pressure on other big model providers to lower prices or relax conditions in order to remain competitive.

• Llama 2 unleashes the innovative potential of the large model, it is an open and flexible platform that allows developers and enterprises to use it to build a variety of applications, and can freely modify and distribute it. The open and flexible nature of Llama 2 enables it to facilitate more experimentation and exploration, resulting in more ideas and solutions. Llama 2 also sheds light on other large models, encouraging them to add functionality or interact with external data sources and tools to provide additional scenarios and value.

Llama 2's pace of development and future competition

According to Meta, Llama 2 is a continuously evolving platform that will be constantly updated and improved to provide better performance and functionality. Meta also stated that they plan to release more datasets, tools, examples, documentation and other resources in the future to help developers and enterprises use Llama 2. In addition, the Meta company also stated that they welcome community feedback, suggestions, contributions, etc. on Llama 2, and will cooperate with other organizations to promote the development of the field of artificial intelligence.

We predict that the open source and free Llama 2 will develop very fast and will be able to reach the level of ChatGPT4 soon. We believe there are several reasons:

• Llama 2 already has a technical level comparable to or surpassed that of ChatGPT4. It not only surpasses ChatGPT3 in the number of parameters, but also surpasses ChatGPT3 in function. The multimodal and multifunctional features of Llama 2 enable it to process and generate different types of data and content, thereby providing more application scenarios and value. Llama 2 also uses a novel training method that speeds up training and reduces computational costs, improving the trainability and scalability of large models.

• Llama 2 is completely open source and free, allowing anyone to use it to build and commercialize applications without worrying about copyright or licensing issues. The open and flexible nature of Llama 2 allows it to attract more developers and businesses, especially those who lack resources or want to remain independent. Llama 2 has also put pressure on other big model providers to lower prices or relax conditions in order to remain competitive.

• Llama 2 is an open and flexible platform that allows developers and businesses to use it to build a variety of applications, and to modify and distribute it freely. The open and flexible nature of Llama 2 enables it to facilitate more experimentation and exploration, resulting in more ideas and solutions. Llama 2 also sheds light on other large models, encouraging them to add functionality or interact with external data sources and tools to provide additional scenarios and value.

For these reasons, we believe that Llama 2 will develop very fast and will be able to reach the level of ChatGPT4 soon. We estimate that within the next year, Llama 2 will be able to reach the number of parameters (4.5 billion) and performance metrics (such as PPL, BLEU, etc.) of ChatGPT4. We also estimate that within the next two years, Llama 2 will be able to reach the functional scope of ChatGPT4 (such as dialogue, summarization, translation, etc.).

Of course, this does not mean that Llama 2 will completely replace ChatGPT4 or other large models. We believe that in future competition, Llama 2 will face the following challenges:

• Although Llama 2 is open source and free, it still requires significant computing resources and expertise to train and deploy. This may limit the ability and willingness of some developers and enterprises to use Llama 2, especially those with high performance, security or stability requirements. Therefore, some developers and enterprises may choose to use the services of other large model providers for better support, assurance or customization.

• Although Llama 2 is multimodal and multifunctional, it still needs to interact with external data sources and tools to provide more application scenarios and value. This may cause some issues or risks, such as data quality, data security, data privacy, data copyright, data compatibility, etc. Therefore, some developers and enterprises may choose to use the services of other large model providers to obtain more complete, reliable or professional data sources or tools.

• Llama 2, while an evolving platform, still requires collaboration with the community and industry to drive development and innovation in the field of artificial intelligence. This may encounter some challenges or resistance, such as community participation, industry standardization, regulatory adaptability, etc. Therefore, some developers and enterprises may choose to use the services of other large model providers to obtain faster, more stable or more compliant updates or improvements.

In summary, we believe that Llama 2 is a disruptive open source megamodel that will change the megamodel landscape and competition. We predict that the open source and free Llama 2 will develop very fast and will be able to reach the level of ChatGPT4 soon. We also analyze how Llama 2 will compete with ChatGPT5 in the future, and point out its strengths and challenges. We look forward to seeing the further development and application of Llama 2, as well as the responses and strategies of other large models.
