Celeris-1 Decision

Celeris-1 Decision is an AI model that evaluates supplied choices and returns a structured decision with probabilities. Celeris launched it on 8 October 2026 as a hosted service.

Define the choices the application can make

The Decision API accepts text, structured information and images. An application defines the allowed output shape, such as a set of categories, and receives values that follow that structure. Explanations can be requested alongside the decision.

Possible applications include sorting incoming requests, choosing a tool or applying a review workflow. A probability describes the model’s assessment. The application still needs tested thresholds and a route for uncertain or consequential cases.

Access and pricing

Celeris lists $0.04 per million input tokens, with output free. The service uses a diffusion model, and the company publishes its own performance and latency comparisons. Those measurements describe its evaluation conditions.

The current offering is hosted API access. The documentation provides the request format and supported decision types. Downloadable weights and fine-tuning are not part of the published offering checked on 15 October.

The language-model directory includes other systems with structured-output and tool-selection features.
