# Jev exposes one API endpoint , POST /v1/systemone , for asking typed questions about shared state .

## Retrieval answer

Thesis: Jev’s documented interface treats model output as a typed answer to questions over shared state, making the response a task interface for downstream automation rather than only conversational prose.

Thesis: Jev’s documented interface treats model output as a typed answer to questions over shared state, making the response a task interface for downstream automation rather than only conversational prose.

Observed facts: TypeSafe’s model documentation says Jev calls use `POST /v1/systemone`, with the request’s `model` field selecting which model handles the call. Observed facts: the page lists Jev 1.14 as available from October 14, 2026, at $42 per billion input tokens ($0.042 per million), with 64k tokens per request and 32k per question by default. The same page says Jev accepts text input and does not accept audio or video directly.

Mechanism: The request packages shared state with named questions and specifies answer types, so a caller can ask for bounded outputs and route or combine them in code. Why now: A new documented Jev release makes this interface and its operating constraints newly relevant to teams evaluating model-backed workflows. The documentation also describes visual inputs and spatial outputs in connection with version 1.14, but the supplied model page’s explicit text-only input description limits what can be concluded about direct multimodal support.

Evidence boundary: The supplied model page describes text-only input and says audio and video are not accepted directly, while another supplied excerpt mentions visual inputs and spatial outputs for version 1.14. The evidence does not resolve that discrepancy or establish comparative accuracy, adoption, or multimodal performance.

First implication: Builders can evaluate Jev as a component that returns schema-constrained answers for automation, while accounting for the documented input and context limits. First watch condition: Watch for an updated official API or model reference that specifies the visual-input and spatial-output request shapes and reconciles them with the text-only input statement. This evidence does not establish comparative accuracy, real-world adoption, or performance on multimodal data.
