I wasted $43 rebuilding a Vectorize index the wrong way — here's the $5.50 fix
A developer detailed how an in-place Vectorize index rebuild led to unexpected costs, with fallback queries to Claude costing $43 over six hours due to silently degrading recall scores. The issue was resolved by implementing a Blue/Green deployment strategy, which reduced the cost to $5.50 and involved a downtime of only 4.19 seconds. The root cause was identified as using overly coarse 512-token chunks for ad insight data, which were improved by switching to 256-token chunks. AI
