ChatGPT
ChatGPT is OpenAI's AI assistant, covering conversation, document and image work, web browsing, Projects, Tasks, custom GPTs, agent actions, and the Codex coding agent, across web, desktop, and mobile.

- Answer quality varies between sessions, making automated processes fragile

- Open weights enable self-hosting and third-party access
- DeepThink handles hard multi-step problems
- Free, capable web assistant
- Consumer service under Chinese jurisdiction
- Not suitable for regulated or confidential data as hosted
