Jev + Opus 5.5 breaks down the cost structure of 24/7 agents
The author uses Jev as the decision layer and Opus 5.5 for research and writing, routing tasks to Research/Write/Review and scoring sources, arguing that most 24/7 agent systems are expensive because the model answers every fork.
jev + opus 5.5 showed me why most "24/7 agent systems" are expensive bullshit the real split isn't "fast vs smart" it's which steps need open-ended reasoning and which only need a bounded decision → jev routes tasks to Research, Write, or Review → scores which sources are worth keeping → sends unsupported claims back for more evidence → moves failures and uncertainty to human review opus owns the expensive part: research, synthesis, planning, writing code owns state, permissions, budgets, retries, and files jev connects them as the decision layer one client brief creates dozens of small forks before one useful file is ready once opus stops answering them all, the workflow becomes cheaper, measurable, and recoverable the full architecture is in my article below ↓
