Independent analysis of AI subscription & API plans

An independent public observatory for AI subscription & pay-as-you-go API plans
Sixteen real upstream API probes per round fingerprint each plan's response distribution, measuring the JS divergence between the claimed model and the served one (the CSL index), 14:00–18:00 peak drift and live throughput. Only reproducible readings are published; credentials are never stored.
Site-wide 7d Median CSL 12.6
Best Baseline Fit (Low Drift) 8.4 (OpenAI)
Highest Peak Drift (High Drift) 45.7 (OpenCode)
Verified Real-API Samples 4 / 15 targets

04Human verification (Cloudflare Turnstile)
Verification boundary: the server uses this credential to make 16 real requests to the official whitelisted API (about 4–10 seconds); the credential lives only in memory and is burned after use; an invalid key or an upstream 401/403 fails loudly and produces no report.
