Claude vs ChatGPT for Research

How each mode works

Anthropic describes Claude Research as a mode where Claude runs several searches that build on each other, then decides what to look into next. The output is a longer report with citations (anthropic.com/news/research). Anthropic's help center explains when to use Research instead of normal web search or extended thinking.

OpenAI's help article describes a deep research flow in which ChatGPT proposes a research plan you can review and adjust. You can track progress, interrupt the run to narrow the focus, and limit searches to chosen sites in the prompt window.

Both products show the plan before the search starts, so you can narrow the scope early. That step matters more than most users expect, because a loose plan produces a loose report with many weak sources.

What the benchmark shows

The DRACO benchmark uses rubric-based grading, with an LLM judge checking each criterion. Hyperresearch published its own run on a 10-task subset: Hyperresearch Deep scored 77.7, Claude Research (Opus) 73.0, and ChatGPT deep research 55.2. These are small samples, and the method page notes that two grades of the same report can differ by about 9 points.

The consumer apps were tested as they ship, and some exports lacked source links, which can lower citation scores. Treat the numbers as one data point, not a verdict.

A fair test also needs the same settings. If one tool ran on a paid model and the other on a free tier, the comparison says more about the plan than the product.

Which one to try first

Choose Claude when you want a long, reasoned report in a chat thread you already use. Choose ChatGPT when you already work inside its plan and want the plan review step. Hyperresearch is our editorial pick when the report must check every cited figure against its source. Run one real question through each, then compare the sources you open.

Keep notes on how long each run took, how many sources it cited, and whether the report answered the exact question you asked. Those three notes tell you more than a headline score. If one tool produces a clean report but cites pages that do not contain the claim, that matters more than a small gap in length or style.

Checklist

• Use the same question, the same date range and the same length request in each tool.
• Read the research plan or outline each tool shows before the run starts.
• Open five cited links and check each figure against the page.
• Note how many sources each report used and whether any link is broken.
• Pick the tool whose cited figures held up on your checks.
