Einleitung: Warum Claude Opus 4.7 für Finanzanalysen?

Das April 2026-Update von Claude Opus 4.7 brachte signifikante Verbesserungen für Finanzanalyse-Workloads. Mit einer 23%igen Steigerung bei numerischen推理-Aufgaben und optimierten JSON-Output für Trading-Strategien ist das Modell ideal für:

Mit HolySheep AI erhalten Sie Zugang zu Claude Sonnet 4.5 zu $15/MTok — 85%+ günstiger als direkt bei Anthropic. Dazu WeChat/Alipay-Zahlung und kostenlose Credits für den Einstieg.

Architektur: Der Finanzanalyse-Stack
