Price escalation
Pricing model changed from flow credits to prompt credits in 2025. Early adopter pricing of $10/month honored through December 31, 2025 for active subscribers. In March 2026 credits were replaced by daily/weekly quotas and new-subscriber Pro rose to $20/month; existing $15 Pro and $30/seat Teams subscribers were grandfathered (Devin docs, checked 2026-10-11).
No price escalation for Aider itself; underlying API costs depend on model provider pricing changes, which can increase substantially with newer SOTA models
