Cross-check facts
Single-model answers feel confident even when wrong. Three models in parallel surface where the consensus actually is.
For researchers and analysts
Don't trust one model with the answer.
Send the same question to up to six frontier models in parallel. Synthesis breaks down where they agree, where they don't, and what only one of them noticed.
Question
What's the strongest evidence that the rise in atmospheric CO₂ since 1850 is anthropogenic, not from natural carbon cycle variation?
Synthesis output (Pro)
Agreement — All models cite the isotopic signature: ¹³C/¹²C ratios in atmospheric CO₂ have been falling, matching fossil-fuel carbon depleted in ¹³C.
Disagreement — Claude emphasizes ocean uptake measurements; GPT-5 emphasizes ice-core reconstructions; Gemini weighs the two more equally.
Unique insights — Only DeepSeek mentions the Suess effect by name and links it to nuclear-test bomb-spike calibration.
Why six models beats one
Designed for triangulation
Synthesis surfaces tension
Pro synthesis groups answers into Agreement, Disagreement, and Unique insights — exactly what you want when triangulating sources.
Compare reasoning, not just outputs
Different models, different chains of thought. See which framing actually helps you understand the problem.
Long context, where you need it
Gemini 2.5 with 1M tokens, Claude Opus with 200K. Pick the model whose context window fits your corpus.
