Highlights
- It picks the best model and reasoning effort for each request, balancing quality, speed and cost.
- Runs on Jev, TypeSafe's first System One model, and adapts as your conversation evolves.
- One endpoint gives you the whole model ecosystem, leveraging the ecosystem's token and spend share.
- OpenRouter's API is OpenAI-compatible, so most SDKs work by swapping the base URL; only the model slug changes.
- Listed on the Decisions card at $0.042 per million input tokens with output free, alongside Jev Latest and Jev 1.13.
Watch out
A gateway listing with no licence or open weights shown, and the routing behavior is described only in OpenRouter's own terms: it does not say which models the router selects among, or how quality, speed and cost are measured. Jev Router runs on a hosted model.
Questions about this entry
Short answers drawn from the linked project or page.
A model listed as typesafe/jev-router that picks the best model and reasoning effort for each request while balancing quality, speed and cost. It runs on Jev, TypeSafe's first System One model, and adapts as your conversation evolves.
According to the listing, one endpoint gives you the whole model ecosystem, leveraging the ecosystem's token and spend share, so you do not wire up model selection yourself.
Yes. The listing says OpenRouter's API is OpenAI-compatible, so most SDKs work by swapping the base URL, and the only thing that changes between models is the model slug.
$0.042 per million input tokens with output free, shown on the Decisions card alongside Jev Latest, which always redirects to the newest model in the Jev family, and Jev 1.13.
TypeSafe's term for models that make fast, structured decisions for software, returning a typed choice rather than free-form text. Jev is the first of them, and Jev Router runs on Jev.
No. It says the router balances quality, speed and cost and adapts over a conversation, but it does not name the candidate models, the reasoning efforts or how each factor is measured, so the routing behavior is not inspectable from the page.

A Claude Code mod that sends each prompt to Jev through OpenRouter and turns the returned 0-3 score into a reasoning effort level, from low to xhigh. Shadow mode is on by default, so it only logs what it would set until you turn it off.
