B2B Role-Play Platform Uses Opus 4.7 for Backend, Haiku 4.5 for Live Chat
Socratize (socratize.io) is a B2B role-play training platform built entirely with Claude models. Teams create custom scenarios for difficult workplace conversations—feedback, client escalations, performance reviews, compliance—and practice via AI-driven role-play.
Claude Stack Details
- Opus 4.7 on the backend: orchestration, game logic, win/loss evaluation.
- Haiku 4.5 for live chat: fast enough for real-time conversation, cheap per-message billing.
- Claude used as a design thinking partner for overall product decisions.
Haiku vs Sonnet Benchmarking
The team compared Haiku 4.5 and Sonnet for the chat role. Key findings:
- Sonnet was worse: more resistant to valid arguments, higher variance, and 8x more expensive.
- Haiku's agreeableness turned out to be a feature for calibrated training scenarios—it allows the conversation to progress naturally without unnecessary pushback.
