Run an iterative deep-research workflow — reformulate the query, search multiple times with refined terms, summarise each source, cross-check for contradictions, and produce a markdown report with inline citations.

Use when the user asks how to build with OpenAI products or APIs and needs up-to-date official documentation with citations, help choosing the latest model for a use case, or model upgrade and prompt-upgrade guidance; prioritize OpenAI docs MCP tools, use bundled references only as helper context, and restrict any fallback browsing to official OpenAI domains.
