The short version
Frontier LLM calls take anywhere from seconds to minutes end to end, because they generate one token at a time. Jev resolves every question in a single parallel pass, which is why TypeSafe quotes 70-500ms.
That is the difference between AI in a background job and AI inside the request path.
Why this matters
Latency is a product constraint, not a performance detail. A 10-second call cannot sit behind a form submission, a typing indicator or a moderation gate — you end up precomputing, caching, or dropping the feature.
At a few hundred milliseconds, the same judgement can happen live: as the user types, as the message arrives, as the draft is saved.
What becomes possible
The pattern to look for is decisions that were previously batched because they were too slow to run live.
- Live moderation and brand-safety gates before content is published
- Routing inbound messages the moment they arrive
- Interactive experiences where the model reacts to structured state repeatedly
- Real-time scoring during editing rather than in a nightly report
Designing for the latency budget
Speed per call is necessary but not sufficient — your budget includes everything around the call. Two habits make the difference.
First, batch questions instead of making several calls; parallel sampling means the marginal question is nearly free. Second, keep the state tight: the fastest request is the one that sends only what the decision needs. See Choice, Score and Noul.
Common mistakes
Real-time AI fails for reasons that have little to do with the model.
- Calling a decision model sequentially in a loop when one call would carry all questions
- Letting the state grow to include context the question never uses
- Setting a timeout tighter than your own network path, not the model
- Forgetting that a fast wrong answer is still wrong — use confidence thresholds
