Terminal demo splits costs between Grok 4.7 writing and Jev routing
The author compares Grok 4.7 with GPT-5.6 Sol Max on benchmarks and price, and says Jev handles each routing call, retry check and whether-to-call-the-LLM decision for $0.0003, with a terminal demo showing the cost split live.
Grok 4.7 matches GPT-5.6 Sol Max on real benchmarks and costs half as much to run DeepSWE v1.1: 71.0% vs 72.7%. basically the same model input tokens: $2 vs $4 - half the price vs Fable 5.1 Max: $2 vs $10 - a fifth of the price and that's before Jev touches anything every routing call, every retry check, every "should this even go to the LLM" decision - Jev handles for $0.0003 a call, so the $2/$6 only fires when something actually needs generation built a terminal that runs this stack live - Grok 4.7 for the writing, Jev for everything else, watch the cost split happen in real time full build below ↓
