Meta elevates standards with the open-source Llama 3 LLM.

Meta has introduced Llama 3, the latest iteration of its cutting-edge open-source large language model (LLM). The tech behemoth asserts that Llama 3 sets new performance benchmarks, surpassing prior top-performing models like GPT-3.5 in practical applications.

"Through Llama 3, our aim was to construct the finest open models that match the quality of today's top proprietary models," Meta stated in a blog post announcing the release.

The initial versions of Llama 3 being released are equipped with 8 billion and 70 billion parameters. Meta reveals that its teams are actively training even larger models, exceeding 400 billion parameters, which are slated for future release along with accompanying research papers.

Llama 3 represents over two years of development, with substantial investments in assembling high-quality training data, enhancing distributed training methods, refining the model architecture, and pioneering instructional fine-tuning techniques.

In terms of performance, Meta's 70 billion parameter model, which has been instruction fine-tuned, surpassed GPT-3.5, Claude, and other comparable LLMs in human evaluations across 12 critical scenarios including coding, reasoning, and creative writing. Meta's 8 billion parameter pretrained model also sets new standards on well-established LLM evaluation benchmarks:

"These are, unequivocally, the best open-source models in their class," affirmed Meta.

Meta is adopting an "open by default" strategy to support a transparent ecosystem in AI development. Llama 3 will be accessible across all major cloud platforms, model hosting services, hardware manufacturers, and AI platforms.

Victor Botev, CTO and co-founder of Iris.ai, commented on the significance of this release amidst a global shift towards AI regulation, "By open-sourcing Llama 3, Meta is committing to transparency, aligning with the increasing focus on responsible AI practices and ethical development."

This move also facilitates broader community engagement, allowing deeper insights into model development and an opportunity to scrutinize different methodologies, which is essential for shaping and enforcing AI regulations.

Alongside the release of Llama 3, Meta has updated its suite of AI safety tools, including the second versions of Llama Guard and CyberSec Eval, and introduced a new tool called Code Shield to prevent insecure code suggestions during inference.

"However, it's crucial to remember that simply being open-source doesn't automatically make an AI model ethical," Botev added. "Addressing the challenges of AI necessitates a comprehensive strategy focusing on data privacy, algorithmic bias, and the societal impacts, which are central to the upcoming AI regulations globally."

While open initiatives like Llama 3 encourage scrutiny and collaboration, their true value will depend on an all-encompassing approach to AI governance compliance and the integration of ethics throughout the lifecycle of AI systems. Meta's ongoing work with the Llama model represents a positive step, but ethical AI requires a continuous commitment from all involved parties.

Meta emphasizes a "system-level approach" to responsible AI development and deployment with Llama 3, which includes extensive safety testing. Nevertheless, developers are urged to implement their own input/output filtering to meet the specific needs of their applications.

Meta AI, the company's end-user product that integrates Llama 3, is touted as the world's leading AI assistant, available through Facebook, Instagram, WhatsApp, Messenger, and the web. This tool supports productivity, learning, creativity, and general inquiries.

Plans are underway for multimodal versions of Meta AI that include vision capabilities, with an early preview expected in Meta's Ray-Ban smart glasses.

Despite Llama 3's significant advancements, some in the AI community remain skeptical of Meta's motivations for its open approach, purportedly for societal benefit. Yet, just a day after Mistral AI set a new standard with its Mixtral 8x22B model, Meta's launch of Llama 3 undoubtedly raises the bar for openly-available LLMs once again.
