AI source-led research benchmark
Produce a decision brief from a fixed source pack plus current public evidence.
Perplexity is the quickest source-discovery layer; Claude is the long-document specialist; ChatGPT is the broadest working environment; Gemini is compelling when evidence already lives in Google Workspace.
The decision table.
Scores are calculated from the four visible profile dimensions below. Open each product review to inspect the underlying strengths and limitations.
Fixed protocol.
- 01Provide the same five-document source pack.
- 02Ask the same ten factual and three synthesis questions.
- 03Require a source for every consequential claim.
- 04Record unsupported claims, correction time and final analyst edits.
What counts as usable.
✓ Every key claim maps to a real source
✓ Sources support the attached claim
✓ Uncertainty is made visible
✓ The final brief needs limited factual correction
