Frequently asked questions

Which is best for Turkish quality?

As of 2026, all three are fluent + grammatically correct + context-consistent in Turkish. The difference is in prompt engineering + system prompt quality. Legal Turkish → Claude; marketing copy → ChatGPT; academic → Gemini or Claude.

Which one for KVKK + GDPR compliance?

All three offer EU/data residency under Enterprise contracts. Claude (default opt-out, training off) is safest. ChatGPT Enterprise + Gemini Workspace also fit. Consumer versions are risky for KVKK.

Monthly cost comparison?

Individual: all three $20/month. Team: ChatGPT/Claude $25-30/seat. Enterprise: negotiated. API: for heavy enterprise use, Claude Sonnet has the best cost/quality, Gemini Flash the cheapest fast.
