Benchmark shows 2.4x token variance across AI-built JS frameworks
Lawson's benchmark quantifies hidden inference costs when agents generate web apps. Token differentials translate into measurable CO2 differentials that existing frontend evaluations omit. The results establish a baseline for energy-aware framework assessment rather than DX or vibe-driven claims.

Future conformance suites and agent harnesses will need explicit energy and carbon accounting alongside Lighthouse metrics. Absent such data, framework selection will continue to externalize environmental costs onto shared power grids.

Opus 5.5: Median token count for Next.js agent builds will exceed 130000 tokens in public replications published before July 2027.
