jev-skip

Chrome and Firefox extension that reads a YouTube video's caption track and asks Jev for a sponsor probability per 30-second segment, painting the seek bar before the intro ends. It reports catching 77% of SponsorBlock's sponsor seconds across 23 videos at $0.0008 per video.

Highlights

  • Reads the caption track and asks Jev for a probability per 30-second segment, with no crowd database.
  • Reports catching 77% of SponsorBlock's sponsor seconds across 23 videos at $0.0008 per video.
  • Slices are tinted by probability, and unsure segments are painted faint and never skipped.
  • It reads text, not audio: no captions means no opinion and the extension does nothing.
  • Published numbers came through a Vercel AI Gateway shim; no live call was made from the extension itself.

Quickstart

bash
git clone https://github.com/valentynkit/jev-skip && cd jev-skip
npm install && npm run build
# Chrome: load dist/chrome-mv3 unpacked, then paste your TypeSafe key in the popup

Watch out

MIT-licensed. Chrome is the only browser it has run in (Firefox MV2 builds but is untested), it needs a TypeSafe key pasted into the popup, and it breaks if YouTube changes how the player requests captions.

After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI? I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev • 20-200x faster • 40-400x

LLM-as-a-judge, sped up

Jev has spoken. It picked which model is AGI. 20–200x faster. 40–400x cheaper. This could make things like LLM-as-a-judge insanely fast and nearly free. (I tried a bunch of prompts and still didn’t burn through $0.10.)

Instant compaction with Jev

This is actually insane. This uses @typesafeai Jev model, as a plugin in Claude to review all the un-nesseasary tool calls, and it takes 1s to run! Like, literally, 1 second to take my Claude session from nearly 1M to ... 86K tokens! 😮 Ask your claude to install it and be  Show more

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

Vercel's fx safety reviewer, 18x faster

We're seeing extraordinary results from @typesafeai. Default mode in 𝚏𝚡 is auto, with a safety reviewer analyzing every command. That reviewer runs on GPT Luna today. Jev is up to 18x faster (p95) *and* more accurate. It's coming to @vercel AI Gateway and likely new default.

We benchmarked fx auto mode (safety) classifier with @typesafeai's Jev. tl;dr: ~5-18x faster and more accurate than 𝚐𝚙𝚝-𝟻.𝟼-𝚕𝚞𝚗𝚊, our current top choice
