What is the Adaptif library?

A React library for adaptive UI driven by a plain-English sentence: describe a situation, and Adaptif shows the intended UI only when the situation is true for the user in front of you.

Your app passes its state and a situation sentence; Jev, TypeSafe AI's decision model, answers from your own server in roughly 100 ms to a second, and the When component renders children or fallback accordingly.

What happens if the model is slow or unsure?

The fallback renders and the app behaves as if Adaptif were not installed, so a slow, unsure or failing answer never blocks the normal interface.

How accurate was the eval?

In a 72-case offline eval, Jev was right on 60 cases while the best hand-written rule for each question got 45 — 83% versus 63% per the README, which links docs/eval.md with results and caveats.

Is it production-ready?

The README calls it an early project with promising early results and links a roadmap of what is next, so treat it as new rather than battle-tested.

What is the licence and status?

MIT, TypeScript, 0 stars, created and pushed 2026-10-11, with topics including jev, jev-compatible, jev-model, react and segmentation.

Where can I see a full example?

The repository includes a candle-shop example under examples/, where a product page moves the burn-time panel to the top after the shopper compares sizes; the digest truncates that link.

Adaptif

Adaptive React UI from a plain-English sentence: a When component asks Jev, TypeSafe's decision model, whether a described situation is true for the current user and swaps the UI, rendering a fallback on slow or unsure answers.

Highlights

Your app passes the state it already has; Jev answers from your own server in about 100 ms to a second and the UI follows.
If the answer is slow, unsure or anything fails, the fallback renders and the app behaves as if Adaptif were not installed.
In a 72-case offline eval, Jev was right on 60 cases; the best hand-written rule per question got 45 (83% vs 63%).
The README calls it an early project with promising early results and links docs/eval.md and docs/roadmap.md.
Repo topics include jev, jev-compatible, jev-model, react and systemone; MIT licensed, created and pushed 2026-10-11.

Quickstart

<When
  situation="The user is doing repetitive work that our Bulk Edit tool could automate"
  fallback={<StandardToolbar />}
>
  <BulkEditSuggestion />
</When>

Watch out

README and GitHub metadata reviewed 2026-10-17; the digest excerpt stops inside the candle-shop example link, so the install steps, the full component API and the eval details in docs/eval.md are not visible. The 83% vs 63% result is the project's own offline eval.

The Open Reimplementations: Local Models That Speak System One

Sep 22, 2026

Closed weights have not stopped the ecosystem from rebuilding the shape in the open. API-compatible servers, retrained heads on small models, and inference-time tricks that skip generation entirely.
