  • There's a comparison to Facebook's evolution, where even small algorithmic changes had immediate feedback and ramifications, but OpenAI doesn't receive the same immediate feedback.

Feedback Challenges:

  • Unlike platforms like Facebook, which could gauge success through metrics like click-through rates, OpenAI has limited immediate feedback mechanisms.

Custom Instructions Feature:

  • OpenAI introduced a "custom instructions" feature that allows users to personalize GPT-4 more effectively.

  • This feature existed in OpenAI's playground and other platforms like Perplexity AI and Character AI. So, while significant for GPT users, it's not a brand-new capability in the AI chatbot sphere.


[19:36 - 32:04]
Facebook's release of Llama 2 represents a significant step in AI development, symbolizing a shift in the balance between open-source and commercial models. Here's a comprehensive summary of the details and implications from the transcript:
