Evidence ledger
TypeSafe reports Jev as materially faster than LLM workflows on its own evaluations.
The launch material reports large latency multiples; X discussion mostly repeats those figures. Trade press (The Register) relays the same vendor figures without independent measurement.

Counterarguments
No independent benchmark in the collected dataset reproduces the headline range on representative workloads.
Open questions
What are p50/p95 latency and accuracy under equal task definitions and concurrency?
This status describes how well the claim is supported by the collected evidence, not whether it is ultimately true. A Vendor Claim is a statement TypeSafe has made about its own product; repetition by others does not upgrade it.

Limitations
- No independent benchmark in the collected dataset reproduces the headline range on representative workloads.
- What are p50/p95 latency and accuracy under equal task definitions and concurrency?

- Probabilistic predicate + deterministic action PlausibleJev supplies fuzzy predicates while TypeScript, policies, and workflows execute constrained actions.
