Meta Dives into Open-Source AI with LLaMA 2 to Challenge OpenAI’s GPT-4
Meta, in a bid to bolster its position in the competitive artificial intelligence (AI) landscape, has revealed its latest large language model, LLaMA 2, making it freely accessible for commercial and research purposes. The decision is seen as a strategic move to compete against OpenAI’s popular language model, GPT-4, which powers tools like ChatGPT and Microsoft Bing.
Since OpenAI’s ChatGPT’s launch last year, major tech entities have been vying to unseat its dominance. Meta’s move to open-source LLaMA 2, with its array of models available in different sizes and a version that can be built into a chatbot similar to ChatGPT, signals the company’s robust response to this challenge.
Meta’s suite of AI models is accessible for download from launch partners such as Microsoft Azure, Amazon Web Services, and Hugging Face. This open-source strategy, Meta believes, not only benefits the AI community by offering a choice between closed and open-source approaches but also aids in learning crucial lessons to improve model safety, bias, and efficiency.
However, like all large language models, LLaMA 2 faces several challenges, including producing inaccuracies and offensive language. Further, Meta has not released information about the data set it used to train LLaMA 2, hence cannot guarantee its freedom from copyrighted works or personal data, as detailed in a research paper shared with MIT Technology Review.
Despite these hurdles, many see the open-source nature of LLaMA 2 as a major advantage. Percy Liang, director of Stanford’s Center for Research on Foundation Models, believes the model poses a significant threat to OpenAI. A more customizable and transparent model, such as LLaMA 2, may facilitate faster product and service creation.
Before its release, LLaMA 2 underwent extensive fine-tuning for safety. Following previous missteps, Meta employed a variety of machine learning techniques to improve the model’s usefulness while reducing potential harm. The training involved 40% more data than the previous model and incorporated feedback from human annotators.
Meta acknowledges that despite these precautions, LLaMA 2, like its counterparts, can produce offensive and problematic language. The company justified not removing toxic data, arguing it could help LLaMA 2 better identify hate speech and prevent accidental filtering of specific demographic groups.
LLaMA 2’s launch coincided with Microsoft’s Inspire event, where further details about the AI tools built into Microsoft’s 360 platform were disclosed. Qualcomm also announced a partnership with Meta to integrate LLaMA into laptops, phones, and headsets for AI-powered apps independent of cloud services from 2024.
Open sourcing LLaMA 2, Meta hopes, will empower businesses, startups, and researchers to experiment and contribute to the rapidly advancing generative AI models. The open-source LLaMA 2 model is likely to garner far-reaching attention, building upon the over 100,000 requests from researchers for the first model. Meta remains confident that this collective endeavor will help identify and solve AI problems more swiftly and effectively.
