How we verify
Every figure on the Builder's Radar traces back to its primary source. No source, no number — no estimated numbers, no filler, no theater.
The rule
The Radar is a command board, not a feed. Before publishing a number we find the primary source (public API, official report, earnings call), store its URL and the date we manually verified it. No source, no number — even if the number is viral. On 27-Sep-2026 we discarded two adoption figures (75.6% and 93.6%) for exactly that reason.
live vs curated
The system is hybrid: ~70% refreshes itself from public APIs, ~30% needs human judgment. Badges say which world each number comes from:
- ● liverefreshed automatically — by the source page itself or by our hourly cron — and stamped with its last fetch time.
- ○ curatedpoint-in-time document (survey/report), manually verified on 27 Sep 2026.
They are never mixed without warning. If an API fails we fall back to the curated figure — never to fabricated values.

Adoption: explicit denominators
The two figures are NOT directly comparable and we say so on purpose: the US surveys working-age adults, China counts the whole country.
Discarded figures: 75.6% / 93.6% — went viral with no primary source findable (searched 27-Sep-2026). No source, no number.
Verified users (globe rings)
A hub only draws its MAU ring when an officially published figure exists. No official figure → no ring. Never estimated:
What stays human
The curator's value lives in the data companies don't publish and in the strategic reading. This is NEVER automated: training costs (almost never in APIs), open vs closed philosophy, “usefulness” context of a model, and the insights that give the numbers meaning. If a figure has no public source, it's written by hand or it doesn't appear.
Region classification
Region follows the real organization, not the repo's language: meta-llama = USA, mistralai = EU (neither USA nor CHINA → OTHER; sides are never forced) and Chinese labs are verified orgs (deepseek-ai, QwenLM, XiaomiMiMo, minimaxai…).
