ELI RESEARCH
ChatGPT vs Perplexity vs Gemini vs Claude for B2B search
The same question can receive different vendors, sources and confidence across assistants.
Cross-engine comparison in progress. No winner cards or overlap percentages are published.
RELEASE STANDARD
Methodology is publishable before findings are.
Eli can publish the question universe, schema, definitions and quality controls before a benchmark release. It will only publish an aggregate when the underlying observations are complete, reviewable and described with their coverage and limitations. Until then, this page makes no performance, ranking or customer-outcome claim.
What is compared
Brands recommended, overlap, citations, source domains, recommendation context and stability—not consumer feature lists.
Controlled question set
All engines receive same benchmark prompt version; record interface/model metadata and do not silently compare different sets.
How to use results
Ask which engines buyers use, where visibility is weak, whether source gaps are engine-specific and whether stability differs.
FAQ
Questions about the research design and release boundary.
Best engine?
Study compares behavior, not universal best assistant.
All cite?
Citation differs by product/context.
Same prompt vendors?
Yes, results can differ.
Track all?
Track buyer-relevant engines.
Overlap authority?
No.
