Recently, Meta released a new open source artificial intelligence model called Llama 2, which is a large 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 versatile platform that can interact with various data sources and tools to provide more application scenarios and value. More importantly, 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 Llama 2 a disruptive innovation that will change the landscape and competition of large models. This article will introduce the technical level of Llama 2, point out the aspects in which it changes the landscape and competition of large models, predict when the development speed of open source and free Llama 2 will reach ChatGPT4, and what situation it will face in the future in the competition with ChatGPT5, and analyze what opportunities and challenges it brings to AI entrepreneurs and the industry.

Llama 2 Technical Level

Llama 2 is a large language model based on the Transformer architecture. It 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 web text. Llama 2 also uses a novel training method developed by Meta itself, called Meta-Learning Accelerator (MLA), which can speed up training without losing quality and reduce computational costs. According to Meta, MLA can reduce training time by 10 times 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 cite them when generating text; Llama 2 can use the Wolfram Alpha API to perform mathematical calculations and display the results when generating text; Llama 2 can use the Google Translate API to perform 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 to a variety of scenarios, such as search, question and answer, 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 freely commercialize them without paying any fees or complying with any restrictions. This is in stark contrast to other large model providers, who usually charge or impose various conditions for using their models. For example, OpenAI charges developers who use ChatGPT a minimum of $100 per month and limits the number of requests per second; Google charges developers who use BERT a minimum of $2000 per month and limits the number of requests per month; Facebook does not charge developers who use RoBERTa, but requires them to comply with its open source agreement and display its logo in the application. Llama 2 does not have these restrictions. It fully complies with the Apache 2.0 open source agreement, allowing anyone to freely use, modify and distribute it without any obligations or responsibilities. This makes Llama 2 more attractive and convenient for developers and businesses, especially those entrepreneurs who lack resources or want to remain independent.

How Llama 2 changes the landscape and competition for large models

The release of Llama 2 is a major breakthrough in the field of artificial intelligence, which will change the landscape and competition of large models. We believe that Llama 2 changes the landscape and competition of large models in the following ways:

• Llama 2 advances the state of the art for large models, surpassing ChatGPT3 not only in terms of number of parameters, but also in terms of functionality. The multimodal and versatile nature of Llama 2 enables it to process and generate different types of data and content, 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 down the commercial barriers of big models. It is the first big model that is completely open source and free, allowing anyone to use it to build and commercialize applications without worrying about copyright or licensing issues. The openness and flexibility of Llama 2 makes it attractive to more developers and businesses, especially those entrepreneurs who lack resources or want to remain independent. Llama 2 also puts pressure on other big model providers to lower their prices or relax their conditions to remain competitive.

• Llama 2 unleashes the innovative potential of big models. It 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 openness and flexibility of Llama 2 enables it to promote more experiments and explorations, resulting in more ideas and solutions. Llama 2 also provides inspiration for other big models, encouraging them to add functionality or interact with external data sources and tools to provide more application scenarios and value.

Llama 2 development speed and future competition

According to Meta, Llama 2 is a continuously evolving platform that will be continuously updated and improved to provide better performance and functionality. Meta also stated that they plan to release more data sets, tools, examples, documentation and other resources in the future to help developers and companies use Llama 2. In addition, Meta also stated that they welcome community feedback, suggestions, contributions, etc. to Llama 2, and will work 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 quickly and will soon reach the level of ChatGPT4. We think there are several reasons for this:

• Llama 2 has reached a technical level comparable to or superior to ChatGPT4, surpassing ChatGPT3 not only in terms of the number of parameters, but also in terms of functionality. The multimodal and multifunctional features of Llama 2 enable it to process and generate different types of data and content, thus providing more application scenarios and value. Llama 2 also uses a novel training method that accelerates training speed and reduces computational costs, thereby improving the trainability and scalability of large models.

• Llama 2 is completely open source and free, allowing anyone to build and commercialize applications with it without worrying about copyright or licensing issues. The openness and flexibility of Llama 2 makes it attractive to more developers and businesses, especially entrepreneurs who lack resources or want to remain independent.
