Jev 1.13.0
A System One model for fast, type-safe structured decisions in software workflows.
Jev 1.13.0 is the model currently reached through jev-latest. It supports typed decisions from text and danger-zone experimental images, but the Box primitive requires Jev 1.14.

Commercial-use note
Hosted commercial access is available under TypeSafe AI terms; verify current account terms before production use.
Context or input limits
The default limit is 64K tokens per request across state and all questions, with a separate 32K limit across state and the single longest question. Sending TypeSafe-Danger-Zone-Long-Context: true raises both per-request and per-question limits to 262K. Image input is experimental and requires TypeSafe-Danger-Zone-Images: true; Box is not available in Jev 1.13.
Pricing
$42 per billion input tokens, equivalent to $0.042 per million input tokens; outputs are free according to the model documentation verified on October 19, 2026.
Latency and rate limits
Rate limits are set per organization and shown in the developer console. Requests over the configured quota return HTTP 429; TypeSafe SDKs retry by default, and teams can contact TypeSafe sales for higher limits.
Strengths
- ✓Typed decision primitives
- ✓Confidence-aware routing
- ✓Free output tokens under the verified published price
Limitations
- ✓Image input and 262K long context are experimental and may change
- ✓The Box primitive is only available with Jev 1.14
- ✓No local deployment or downloadable weights are documented
- ✓Aliases can move to a newer model version
Safety notes
- ✓Calibrate confidence thresholds on representative data
- ✓Route uncertain or high-impact decisions to human review

Implementation guidance
Keep the declared inputs and outputs visible in code review. Validate every model response before it reaches a database, API, or customer-facing action.
