The user comments convey mixed feelings about Google Gemini's API, particularly highlighting frustrations with the Vertex AI system. Users report that while Vertex AI may complicate the experience, the non-Vertex APIs offer user-friendly features such as easy API keys, good documentation, and OpenAI-compatible API endpoints which facilitate migration from OpenAI to Gemini. Concerns remain about token counting limitations and the fragmented nature of Google's API documentation. Many respondents reflect on Google's past API-centric approach and express disappointment in its current, seemingly internal-focused strategy, which they feel neglects external developer needs.
