Question 1

Can o3 do Deep Research?

Accepted Answer

o3-deep-research is our most advanced model for deep research, designed to tackle complex, multi-step research tasks. It can search and synthesize information from across the internet as well as from your own data—brought in through MCP connectors.

Question 2

Is 4o or o3 better for research?

Accepted Answer

After testing both extensively The difference is shocking. The performance gap: 4o reasoning IQ: 67-84 o3 reasoning IQ: 117 That's smarter than most humans. 4o trades logic for speed. o3 trades speed for accuracy.

Question 3

Can OpenAI API do Deep Research?

Accepted Answer

To use deep research, use the Responses API with the model set to o3-deep-research or o4-mini-deep-research . You must include at least one data source: web search, remote MCP servers, or file search with vector stores.

Question 4

How good is o3-Deep-Research?

Accepted Answer

It's not just that Deep Research is likely to be useful across a wide range of industries. Its performance demonstrates the impressive capabilities of the underlying o3 model. Deep Research discovers information in the same iterative manner as human researchers. It will do a search, find a document, and read it.

Question 5

Is o3 smarter than o1?

Accepted Answer

With an impressive 96.7% accuracy, the o3-mini-high vs o1 comparison shows o3 significantly outperforms o1's 83.3%. This leap showcases o3's superior ability to handle complex tasks. Mathematics, a crucial benchmark, highlights the model's capacity to grasp abstract concepts fundamental to scientific understanding.
