Reviewer scorecard
“The free tier is incredibly generous. Multimodal capabilities and grounding with Google Search are unique advantages.”
“The simplest way to get typed, validated outputs from LLMs. Pydantic integration is natural for Python developers.”
“Google's track record of killing products is concerning, but the Gemini API is too useful to ignore.”
“Does one thing perfectly. No over-abstraction, just structured outputs. The anti-LangChain.”
“Google's data advantage and multimodal-first approach make Gemini a serious contender in the model race.”
“Structured outputs are the bridge between LLMs and traditional software. Instructor makes that bridge trivial to build.”
