TIL: Exploring OpenAI’s o4-mini-deep-research Model (Small-Scale Deep Research)

TIL: Exploring OpenAI's o4-mini-deep-research API Model
Original post: TIL: Exploring OpenAI's deep research API model o4-mini-deep-research
I recently contributed to a pull request by Manuel Solorzano that added pricing information for OpenAI’s o4-mini-deep-research and o3-deep-research models to llm-prices.com.
These models were released in June (details here) and are fully documented on the Deep Research Guide pages.

Why I Tried It
I realized I had never used these models before, so I decided to test o4-mini-deep-research by asking it to research the locations of surviving orchestrions — a topic I’m personally fascinated by (more here).

Test Results & Cost
- API usage cost: $1.10
- Output: A list of 19 orchestrions (only one fact-checked so far)
- New tooling created:
- Deep Research Viewer — visualizes Responses API traces from deep research models.
- Mocked-up listing page showing the orchestrions identified.
