this is pure f*cking gold for anyone running coding agents Jev founder Diogo Amogo wrote a PDF on building a Jev harness the promise: > 200x faster > 400x cheaper the model hasn't been the slow part for a while the speed and the cost sit in the harness... show more

The model got fast. Everything around the model became the bottleneck.

200x faster is wild but 400x cheaper is what actually makes this viable at scale

People are big ants and many will be left without work

That's a huge optimization. I will get the PDF this weekend and try it out myself.

原来瓶颈一直都在外壳设计上啊受教了

Small correction: this paper is not by the Jev founder. It’s an independent note based on his design ideas The key detail is actually printed on the cover: it says “independent working note, not affiliated with TypeSafe.

👀

finally a harness worth actually setting up

that 400x cost drop is sexy. I’d bet the secret’s in Jev harnessing parallel context windows rather than raw compute cuts. Makes those coding agents run tighter without bleeding cash. Efficient brains are always attractive to me. 😉

200x and 400x on what baseline though, curious if that's against a naive setup or an already decent one

The harness as bottleneck—finally someone naming the thing we all felt.

Totally agree, redundant tool loops and bad scaffolding waste way more time than token generation ever does.

It is easy to just come up with an idea. Now test it, compare, run benchmark, not just speed and cost numbers, but quality - that would be gold. Anyone?

Setup compounds quickly.
