- GPT-5.6 (Sol / Terra / Luna)
- OpenAI's model family announced with the ChatGPT-Codex merge. Sol is the flagship for long-running agentic tasks; Terra and Luna are smaller models aimed at everyday chat and knowledge-work tasks.
- Codex
- OpenAI's coding agent product, now merged into the main ChatGPT app as a 'Work' tab alongside chat, sitting next to computer-use and browser automation features.
- Computer use
- An agent capability that lets a model directly control a computer's mouse, keyboard, and browser to complete tasks, running in the background rather than taking over the user's screen.
- Agent loop
- A workflow where an agent is given a success criterion and a feedback set (reference examples or a working app to test against), then repeatedly revises and re-scores its own output until it clears the bar.
- Record and replay
- A Codex feature that converts a recorded screen session into a reusable agent skill, so a repetitive knowledge-work task only needs to be demonstrated once instead of scripted into a prompt.
- Building-block economy
- The idea that AI agents increasingly assemble pre-built services (databases, sandboxes, agent frameworks) rather than writing infrastructure from scratch, letting a single prompt stitch together tools like Lego pieces.
- Agent-native app / mini app
- Software designed to be operated primarily by an AI agent rather than a human, surfaced inside a chat interface only when the agent needs it.
- Sites
- A ChatGPT/Codex feature that turns a text prompt directly into a hosted, shareable website, without needing a separate deploy step to a platform like Vercel.
