ChatGPT introduces multi-step deep research
A research mode searches and synthesizes web sources into a cited report.
A historical account of this event. Usage notes are YLEM editorial analysis; check the provider for current features and prices.
What changed
OpenAI launched deep research for extended web investigation rather than a quick reply. Its announcement also acknowledges possible factual errors, faulty inferences and difficulty separating reliable information from rumors.
What this means in practice
Define a question, time range and comparison criteria before starting. For example: compare three services on export formats and collaboration, and request official sources for every feature claim.
How to read the result
Audit the few claims that determine your decision. Follow their citations, check publication dates and separate the source's findings from the model's interpretation.
