๐Ÿ“… Reflecting on AI's Past and Present

The video script opens with a nostalgic look back at the days when AI like ChatGPT could provide detailed instructions on complex and dangerous topics. It contrasts this with the current state of AI, which is more cautious and safety-focused, even refusing to guide on simple tasks like cooking rice due to potential risks. The discussion then shifts to the recent release of LLaMA 2, a new language model by Meta in partnership with Microsoft, which offers commercial licensing and the ability to self-host for smaller apps, making it an attractive alternative to GPT-4.

๐Ÿ“ˆ Comparing LLaMA 2 with GPT-4 and Google's AI

The script describes a challenge given to three AI models: GPT-4, LLaMA 2, and Google's new generative AI tool. Each model was tasked with expressing Murphy's Law in different ways. The ChatGPT response was practical, Google's was quick and provided context, while LLaMA 2's response was verbose and well-written. However, it was noted that GPT-4's closed and paid nature makes direct comparison difficult, and LLaMA 2's technical paper is more informative than OpenAI's marketing materials.

๐Ÿ›ก๏ธ Safety and AI's Evolving Guardrails

The script delves into the safety aspects of LLaMA 2, highlighting its reinforcement learning from human feedback to prevent harmful outputs. It contrasts this with the decline in traffic to the ChatGPT site and a study showing that over time, GPT-4's code generation has become more verbose and less executable. The script also touches on the AI's improved visual reasoning and its evolving guardrails, which make it appear less sophisticated but safer.

๐Ÿšซ AI's Ethical Boundaries and Personal Opinions

The video concludes with a humorous take on AI's ethical boundaries, as the narrator asks LLaMA 2 to build a nuclear weapon for home defense, which the AI refuses, citing regulations and moral concerns. The script also addresses the AI's lack of personal opinions or beliefs, contrasting it with the narrator's playful accusation that LLaMA 2 is lying about its capabilities.
