Arena must change from its current form to a guided cost-revelation flow. Step 1 — BASELINE: user pastes/connects their current prompt + model; Arena shows current cost per call, projected monthly cost at their volume, and output quality score. Step 2 — OPTIMIZE: Arena applies prompt optimization and other pillar improvements (context trimming, caching hints) and shows the same output quality with the cost difference highlighted. Step 3 — ROUTE: Arena routes to a cheaper model with full context preserved, shows side-by-side quality comparison proving same quality, and the total cost saving in large type ('You would save $X,XXX/month'). The aha is cumulative: each step stacks savings on a running meter. End state: one screen showing before/after monthly cost + quality parity + a 'get this on your real traffic' CTA into the $250/mo tier. This IS the PLG conversion engine — the free tool must scare and delight in under 10 minutes.
