What is Llama 2?

Emerging from the shadows of its predecessor, Llama, Meta AI’s Llama 2 takes a significant stride towards setting a new benchmark in the chatbot landscape. Its predecessor, Llama, stirred waves by generating text and code in response to prompts, much like its chatbot counterparts. However, Llama’s availability was strictly on-request to guard against potential misuse – a move that didn’t entirely prevent it from leaking online and circulating among AI enthusiasts.

Stepping away from the restricted availability approach of its precursor, Llama 2 will embrace a broader stage. Ready for fine-tuning on platforms like AWS, Azure, and Hugging Face’s AI model hosting platform, it’s set to be a game-changer. With Meta’s assurance of a smoother run, Llama 2 is prepared to dominate not just Windows, thanks to Meta’s collaboration with Microsoft, but also smartphones and PCs equipped with Qualcomm’s Snapdragon system-on-chip.

Safety first

As we celebrate the dawn of Llama 2, it’s important to highlight the cornerstone of this model: safety. Meta’s commitment to delivering accurate results and curtailing misuse has been a guiding principle in developing Llama 2. Acknowledging issues with early LLMs such as GPT, which have been plagued by ‘hallucinations’, misinformation, and harmful perspectives, Meta has gone to great lengths to avoid these pitfalls.

With an intensified training regimen focusing on ‘truthfulness’, ‘toxicity’, and ‘bias’, Meta has fortified Llama 2’s defenses against these issues. As a result, Llama 2 Chat is lauded as a significant improvement over its pretrained version in terms of both truthfulness and toxicity.

“The percentage of toxic generations shrinks to effectively 0% for Llama 2-Chat of all sizes: this is the lowest toxicity level among all compared models. In general, when compared to Falcon and MPT, the fine-tuned Llama 2-Chat shows the best performance in terms of toxicity and truthfulness.”

This breakthrough potentially transforms Llama 2 into a reliable generative AI tool for a wider array of tasks. Despite GPT’s impressive human-like text generation capabilities, the need to meticulously check and cross-check its outputs highlights a significant challenge. With Llama 2, Meta aims to put these concerns to rest, crafting an AI that can be trusted without a constant need for surveillance.

Llama vs Llama 2

Diving into the nuances between Llama and its successor, Llama 2, Meta’s extensive whitepaper illuminates an array of distinguishing features.

The star of the show, Llama 2, dons two distinct roles – Llama 2 and Llama 2-Chat. The latter is particularly optimized for engaging in two-way conversations. They are further classified into distinct versions characterized by their level of sophistication, ranging from 7 billion parameter to a whopping 70 billion parameter model. If you’re wondering about “parameters,” think of them as the facets of a model that are honed through training data, defining the prowess of the model in a specific task like generating text.

When it comes to the training of Llama 2, the model was educated on two million tokens – elements of raw text such as “fan,” “tas,” and “tic” in the word “fantastic.” This represents a significant leap from Llama’s training, which was based on 1.4 trillion tokens. As a general rule of thumb in the generative AI sphere, the more tokens, the merrier. For comparison, Google’s premium large language model (LLM), PaLM 2, was reportedly trained on 3.6 million tokens, while speculations suggest that GPT-4 was brought up on trillions of tokens.

Maintaining an air of mystery, Meta refrains from disclosing the specific origins of the training data in the whitepaper. What they do share is that the data is predominantly from the web, primarily in English, and does not originate from Meta’s own products or services. The focus, they highlight, is on text that leans towards a “factual” nature. Now let’s find out how to use Llama 2.

Llama vs ChatGPT

When it comes to LLMs capable of generating strikingly human-like text, both LLaMA and ChatGPT have emerged as game-changers. These models’ ability to weave coherent and contextually appropriate language makes them indispensable across diverse applications. Despite their shared strengths, certain key distinctions set them apart.

Presented by Meta, LlaMA (Large Language Model Meta AI) is a fresh face on the LLM stage. Its design emphasizes efficiency and minimal resource demand, making it more accessible to a broader audience. LlaMA’s standout feature is its availability under a non-commercial license, allowing researchers and organizations to easily incorporate it into their work.

Uncovering the power of top-notch LLMs

Contrastingly, OpenAI’s ChatGPT holds a reputation as one of the most advanced generative AI systems in today’s world. It’s celebrated for its uncanny ability to generate natural language text that often mirrors human-authored content.

The foundations of both LlaMA and ChatGPT lie in transformers – a type of artificial neural network leveraged in machine learning to analyze vast data volumes and generate novel content or predictions based on the gleaned insights.

One crucial factor that separates LlaMA from ChatGPT is their size. LlaMA, with its emphasis on efficiency and low resource consumption, is more compact than many other LLMs. While it has fewer parameters, it counterbalances this by optimizing its efficiency.

ChatGPT is a giant in the LLM world, boasting over 175 billion parameters. Its substantial size necessitates a hefty computational power but also enables it to generate intricate and sophisticated language.

The learning approach for both LlaMA and ChatGPT is unsupervised, meaning they don’t rely on human-labeled data to learn. They train on extensive text data sourced from the internet or other resources, creating new text based on recognized patterns.

A key difference between the two lies in the nature of their training data. LlaMA hones its skills on a wide spectrum of texts, from scientific articles to news stories. In contrast, ChatGPT’s training ground primarily comprises internet text like web pages and social media content. This suggests LlaMA might be a better fit for generating specialized or technical language, whereas ChatGPT may shine in creating informal or conversational language.

Both LlaMA and ChatGPT represent the cutting edge of language models, having the potential to revolutionize natural language processing applications. Despite their differences, they share a core capability: generating impressively human-like language, promising exciting applications in chatbots, content generation, and beyond.
