Hosted Jev or local Kev: what should you compare first?

Kev's original repository provides pretrained weights, instructions for starting a local server, and examples compatible with the shape of TypeSafe System One calls. It is a community project; a similar interface does not make it the same model as official Jev. The README also presents the author's evaluation methods and limitations. This post has not reproduced those results and does not use them to declare either approach better. Points to debate The editors suggest establishing your constraints before comparing model sizes or leaderboard scores. Whether data may be sent to an external service, what hardware is already available, peak concurrency, and the ability to maintain and upgrade the system all affect the choice. Local deployment requires accounting for hardware and operations costs; hosted calls require network conditions and service quotas to be included in measurements. A single model execution time must not be confused with the duration of a complete request. If your application already uses Jev, you can begin with an offline comparison on the same set of de-identified samples, keeping questions, candidates, and labels identical while comparing judgment quality, probability behavior, and failure cases. Then measure response times with realistic input lengths, cold starts, and queuing. Establishing a working connection is only integration verification; meeting a business acceptance target requires a separate body of evidence. Discussion questions 1. When choosing local or hosted inference, are you constrained first by data boundaries, hardware, or operational capacity? 2. Which inputs and settings would you hold fixed to avoid mistaking a prompt change for a model improvement? 3. Which metrics must cover the complete request rather than merely quote model execution times from a repository?
