A developer detailed four unexpected challenges encountered after migrating a service from Anthropic's Claude to Google's Gemini 2.5 Flash. The primary motivation for the switch was Gemini's significantly lower API costs, which were found to be up to 20 times cheaper than Claude Sonnet. However, issues arose with Gemini's default "thinking" mode impacting search functionality and increasing costs, a bug in a nightly batch job that led to excessive API calls for new users, and incorrect pricing configurations that misrepresented actual expenses. Additionally, the service inadvertently continued to charge users based on older, lower pricing tiers, resulting in financial losses. AI
