By my count, there are three successful types of language model product:

- Chatbots like ChatGPT, which are used by hundreds of millions of people for a huge variety of tasks

- Completions coding products like Copilot or Cursor Tab, which are very niche but easy to get immediate value from

- Agentic products like Claude Code, Codex, Cursor, and Copilot Agent mode, which have only really started working in the last six months

On top of that, there are two kinds of LLM-based product that don’t work yet but may soon:

- LLM-generated feeds

- Video games that are based on AI-generated content
