Model Fusion

Model Fusion sends one prompt to two or three models at once, then a judge model reads every answer and writes one merged reply. You get the synthesis and each participant’s output.

​

Where

• API, with POST /api/v1/chat/fusion and an API key.
• Browser App, from the composer. See Fusion.
• Plugin, with /nito:fusion or $nito:fusion. See Fusion in the plugin.
• MCP, through the nito.chat_fusion tool on the hosted endpoint.

Fusion needs a paid plan. See Plans.

​

How It Works

1. Fan-out. Anonymous and Private models run concurrently; all-Confidential sets run one at a time inside attested routes.
2. Synthesis. A judge model merges the answers. For all-Confidential sets, one Confidential participant is the judge, so the synthesis stays attested.

The result arrives once every participant and the synthesis finish. A failed participant is reported in its own entry.

​

Privacy Rules

• Anonymous and Private models can mix.
• Confidential models run only with other Confidential models, judge included.
• Encrypted Fusion runs in the Browser App, with the synthesis as an explicit step.

​

From Your Own Code

Call POST /api/v1/chat/fusion with models and messages. The response includes each participant and the synthesis. Each participant and the synthesis meter separately. A paid plan with Fusion access is required; prepaid balance alone does not unlock it.
