Introducing ChatGPT search
OpenAI launched ChatGPT search on Oct. 31, 2024 for Plus, Team, and SearchGPT waitlist users, adding web answers with source links inside ChatGPT. It can trigger web search automatically or manually, shows a Sources sidebar, and uses a fine-tuned GPT-4o post-trained with distilled outputs from o1-preview. The shift to watch is distribution: search is folded into chat, not a separate search engine hop.
Why it matters: This is a same-day OpenAI product launch, not a minor feature tweak; search is merged into the chat UI, so HKR-H/K/R all pass. The post confirms source-linked web answers and launch conditions, and the move hits search distribution directly, which pushes it to P1.
