Grok 4.7 plus Jev builds a low-cost agent system
The author uses Grok Bot with Jev as a pre-check layer that asks whether each step is worth doing, claiming tool calls drop from 25 to 8, prompts from 17.8k to 9.5k tokens, and bills by about 40%.
I JUST MERGED THE NEW GROK 4.7 + JEV AND BUILT THE BEST AI AGENT SYSTEM I'VE EVER SEEN it's cheaper and faster than what 95% of people are running, and it took me 7 minutes, ofc repo in the end Grok 4.7 is the brain and Jev is the reflex, and the reflex costs $0.042 per million tokens before every move, one question: is this worth doing? it answers in 239 ms and costs almost nothing here's the whole setup: → make a key on typesafe and let grok bot keep it in the secure field → tell grok bot to install jev on its own computer and run one test → add one rule: before any browser, research or extra bot, ask jev first → let it watch for a day without touching anything, then read what it would have done → turn it on, and keep the last word on anything you can't undo that's it. no code, no servers, no fine-tuning the part nobody posts: my agent carried 25 tools on every single step, even when it needed 3. jev cut it to 8 my first prompt went from 17.8k tokens to 9.5k. the bill dropped by up to 40% 25 questions to jev take the same time as one, because it answers all of them at once This amazing setup is available for everyone, explore my repo below for more details, also check out my article below ↓
