Doesn't seem like access is available to try "deep research" yet on OpenAI, so I can only speak to what I tried, which was their examples on the blog post (using DeepSeek w/ R1 + Search) and results were pretty similar.
AFAIK OpenAI's current offering uses 4o, and it does a web search and then pipes it into 4o. I'm guessing adding CoT + other R1/o3 like stuff is one of the key effective differences. But time will tell how different it is. Maybe it's a dramatic improvement.
