With the advancement of artificial intelligence technology, video understanding has become increasingly important. Against this backdrop, the VideoLLaMA 2 project has emerged, aiming to advance video large language model spatiotemporal modeling and audio comprehension capabilities. This project is an advanced multimodal language model that can help users better understand video content.

Google has launched a new series of open-source models called 'Gemma'. A comparison between Gemma, Llama 2, and Mistral. The design principles and features of Gemma. Characteristics of the GeGLU activation function used in Gemma.

WhatsApp is testing the launch of an AI chatbot powered by Llama 2. Meta has developed a smooth and realistic conversational experience using the advanced Llama 2 large language model. Users can initiate the integrated AI chatbot via shortcuts to perform tasks, providing a more convenient communication experience. Currently, the feature is only available to a limited number of test users, with a full rollout expected in the coming days.

Meta has introduced the next-generation large language model Llama 2, which surpasses GPT-3.5 Turbo and Claude 2 on certain tasks. Released in July 2022, Llama 2 offers three different model sizes: 7 billion, 13 billion, and 70 billion parameters. Meta is collaborating with Dell to assist enterprise customers in deploying Llama 2 models locally instead of solely relying on cloud services. The Llama 2 model is open-source and available for research and some commercial use. Meta has partnered with Microsoft and Amazon.

Meta has released the Llama2-Long model, which does not increase computational demand when processing long texts while still maintaining excellent performance. The model employs continuous pre-training, improved positional encoding, and data mixing strategies to reduce computational overhead by up to 40%. It performs outstandingly on both long and short tasks, surpassing other long-context models and has the potential to revolutionize the field of natural language processing. The model shows significant improvements in encoding, mathematical, and knowledge-intensive tasks, even surpassing GPT-3.5. The release of the Llama2-Long model provides a powerful solution for handling long texts.

ELYZA has released the Japanese LLM 'ELYZA-japanese-Llama-2-7b' based on Meta's Llama 2, with a parameter count reaching 7 billion, performance comparable to GPT-3.5. The model has undergone additional pre-training and unique post-training, achieving the highest scores in a 5-level manual evaluation. Although it has not yet reached the level of closed LLMs, it is already on par with GPT-3.5. ELYZA has successfully developed LLMs in other languages, including English.

IBM has announced that it will host Meta's AI language program on its enterprise AI platform watsonx. This collaboration will provide enterprise users with enhanced AI language capabilities. This will drive IBM's innovation and growth in the enterprise AI sector.

Microsoft recently announced a series of upgrades to its AI suite. They announced support for the Llama 2 large model and the launch of the GPT-4 version of Office. Llama 2 is a new AI model with powerful natural language processing capabilities. The GPT-4 version of Office is a premium office suite offered by Microsoft, available for users through a $30/month rental model. This upgrade signifies that Microsoft's AI technology will become more advanced and comprehensive.
