Per-vendor weekly score over training-data continuity for 200 AI vendors. Grades A–F derived from median silence, 180-day abandonment, and volatility of publishing cadence. The index is computed deterministically from the public Observatory feed and signed Ed25519 — anyone can reproduce it.

Formula

CCI = 100 × max(0, 1 − 0.50·clamp(median_silence / 365, 0, 1) − 0.30·abandoned_180d_ratio − 0.20·clamp(stddev / 180, 0, 1))
