- Vendor Stated Claims: Self-reported figures from official provider documentation under optimal network conditions. For automated AI services (e.g. CapSolver, CapMonster Cloud), sub-3s claims reflect token-based workflows (e.g. reCAPTCHA v2 or Turnstile). For human-assisted platforms (e.g. 2Captcha), vendor figures represent workforce queue turnaround across all challenge formats.
- SolversReview Benchmark Telemetry (Oct 2026): Sample probe measurements recorded during our benchmark tests. 2Captcha was sampled on Normal Image OCR (~4.91s), Google reCAPTCHA v2 (~14.0s, 100% sample completion), and Cloudflare Turnstile (~2.98s, 100% sample completion). Providers not included in the active probe sample rotation are marked accordingly.
