ai chat
What it is
AI chat models are the conversational layer on top of large language models. You describe a problem in plain language; they reason through it, draft a response, and keep the context of everything you've said in the conversation. They're not search engines — they synthesise rather than retrieve.
Why now
The 2023–2025 generation of models crossed a threshold: they became genuinely useful for open-ended intellectual work, not just template completion. The gap between what a competent human assistant and a frontier AI can produce in a single session closed fast.
