Real tasks forced reading the skills docs and using state properly.

Jev 学费还是要付的，刚开始觉得，每次请求这么便宜，每个月 $5 妥妥够用，一个真实任务下来就教做人：好好研究官方 skill，学会如何正确使用 state 和按分组问问题。

The author expected $5 a month to cover their Jev use. Real tasks proved otherwise: they had to study the official skills, pass state correctly, and change how they asked. The post is the cost lesson, not a benchmark.

I built a browser extension with Jev @typesafeai that can hide/collapse posts on X based on natural language. It's so fast that it's not noticeable and insanely cheap...this must be the future of "ad blockers" and content firewalls.

found the perfect use case for @typesafeai Jev: instant compaction in 2026, why is compaction still a summarization prompt? Jev can make it instant by scoring every tool call and dropping what’s irrelevant

I think I just cooked something 🔥 jev(): a PostgreSQL extension that searches your whole database in natural language. No index, no embeddings, just one function. WHERE jev(people, 'could work from home') or WHERE jev(people, 'name sounds european') 129 rows judged in ~1s for $0.0009. Second run: 6ms from cache.
