Comparison workspace

Find agreement. Weigh differences.

Ask once, read each model answer in place, and use the consensus layer to see what holds up, what conflicts, and what needs a closer look.

Consensus Answer

The Nile is the conventional answer at about 6,650 km. The Amazon is the largest river by volume and may be longer under newer measurements — the models agree the dispute itself is real.

Differences

Three models call it settled for the Nile; quoted lengths differ by up to 600 km.

Product walkthrough

The workflow is the interface.

The preview mirrors the actual consens.io flow: one prompt, parallel model work, then a consensus view that keeps agreement and disagreement separate.

Start from one prompt

Use the same input surface from the app, including Agent Mode, Auto Consensus, and Deep Think.

Watch Agent Mode run

Selected models are grouped into one run, with chips and a live activity state.

Separate agreement from doubt

The final panel separates what the models agree on from what still conflicts.

Response from ChatGPT

GPT-5.5

The Nile is traditionally listed as the longest river at about 6,650 km, with the Amazon second at roughly 6,400 km.

Response from Mistral

mistral-medium-3-5

Most references name the Nile at ~6,650 km, though some recent studies argue the Amazon is actually longer.

Response from Claude

claude-opus-4-8

It depends on measurement: the Nile is the classic answer, but if the Pará estuary is counted, the Amazon may exceed 7,000 km.

Response from Gemini

gemini-3.1-pro-preview

The Nile, at about 6,650 km. A 2007 Brazilian expedition measured the Amazon at 6,992 km, but that result is not widely accepted.

Response from DeepSeek

deepseek-v4-pro

The Amazon is the largest river by discharge. By length, the Nile is usually cited first with estimates of 6,550–6,700 km.

Response from Grok

grok-4.3

Officially the Nile. Some expeditions put the Amazon ahead — it depends on where you decide the river starts.

Consensus Answer The Nile by convention, the Amazon by some measurements.

The models converge: the Nile is the conventional longest river at about 6,650 km, while the Amazon — the largest river by water volume — measures roughly 6,400 km, or up to 6,992 km if a disputed 2007 survey is accepted. A careful answer names both rivers and the measurement dispute instead of hiding it.

Differences What still needs checking.

Three models state the Nile as settled fact; three treat the 2007 Amazon measurement (6,992 km) as a credible challenger. Quoted lengths differ by up to 600 km.
