When will the reasoning models support web search? They used to be able to do it. Then they stopped supporting web search. Finally we were told that they would have support soon once responses api is up to speed and has feature parity.
Any timeline on when web search will become available again?
Interestingly I see no official recognition of the limitation in the documentation?:
https://platform.openai.com/docs/guides/tools-web-search
In any case what is stopping you using a local function? (for the time being)
Latency, and the added cost of querying another LLM just to run a web search. It worked perfectly fine during the time OpenAI “accidentally” left it in the API so there isn’t any obvious restraint here.
must be new here. 
You are not querying another LLM. And the cost is minimal.
I use https://jina.ai/. Pretty good.
Thank you for clarifying. I didn’t assume you meant to move off-platform, although I think that doing so would also fix many more problems than the one being discussed 
They will get there. They have so many moving parts 
I am only interested in O3 and O4-mini for web search because they can do it agnatically. With Jina or Exa you have to build the scaffold for agentic search.
But it takes all of half a day, if that!
Plus you then get more granular control over which service you use (which may or may not have superior capability) and how much you spend.
Do you know of a guide on building high quality agentic search?
From my experience, O3 with Search outperforms everything else I have tried by a very large margin.
Any idea when this will be fixed? It’s weird that o3 + web_search tool is not supported while it works well on gpt-4.1
Web search and Deep Research are now available for the O series models.
