Cohere API	Specializes in enterprise RAG and classification; less emphasis on real-time voice/video.

Reputation

Gemini API is recognized for powerful multimodal capabilities and integration within Google's ecosystem, appealing to developers leveraging Vertex AI. Criticisms include data privacy concerns as Google collects prompts and usage data, plus occasional rate limiting in free tier. It maintains strong developer adoption due to free access and model performance rivaling competitors.
