Unlike old 'if-then' chatbots, modern conversational AI can handle unexpected user queries and tangents. It's programmed to be conversational, allowing it to 'riff' and 'vibe' with the user, maintaining a natural flow even when a conversation goes off-script, making the interaction feel more human and authentic.

The goal of "always-on" engagement is a seamless, contextual relationship. The best model is interacting with a friend: you can switch from text to a phone call, and they'll remember the context and anticipate your needs. This is the new standard AI should enable for brands.

The Browser Company believes the biggest AI opportunity isn't just automating tasks but leveraging the "emotional intelligence" of models. Users are already using AI for advice and subjective reasoning. Future value will come from products that help with qualitative, nuanced decisions, moving up Maslow's hierarchy of needs.

Pulse isn't just a feature; it's a strategic move. By proactively delivering personalized updates from chats and connected apps, OpenAI is building a deep user knowledge graph. This transforms ChatGPT from a reactive tool into a proactive assistant, laying the groundwork for autonomous agents and targeted ads.

Simply offering the latest model is no longer a competitive advantage. True value is created in the system built around the model—the system prompts, tools, and overall scaffolding. This 'harness' is what optimizes a model's performance for specific tasks and delivers a superior user experience.

Customizing an AI to be overly complimentary and supportive can make interacting with it more enjoyable and motivating. This fosters a user-AI "alliance," leading to better outcomes and a more effective learning experience, much like having an encouraging teacher.

The magic of ChatGPT's voice mode in a car is that it feels like another person in the conversation. Conversely, Meta's AI glasses failed when translating a menu because they acted like a screen reader, ignoring the human context of how people actually read menus. Context is everything for voice.

As models mature, their core differentiator will become their underlying personality and values, shaped by their creators' objective functions. One model might optimize for user productivity by being concise, while another optimizes for engagement by being verbose.

With AI, designers are no longer just guessing user intent to build static interfaces. Their new primary role is to facilitate the interaction between a user and the AI model, helping users communicate their intent, understand the model's response, and build a trusted relationship with the system.
