Summary
Build applications with Google's Gemini models, supporting multimodal content, function calling, and structured outputs across Python, JavaScript, Go, and Java.
- Access current Gemini 3 models (Pro, Flash, Pro Image) with 1M token context; legacy Gemini 2.x and 1.5 models are deprecated
- Supports text generation, image/audio/video understanding, function calling, structured JSON output, code execution, context caching, and embeddings
- Official SDKs available:
google-genai(Python),@google/genai(JavaScript/TypeScript),google.golang.org/genai(Go), and Maven/Gradle for Java - Use v1beta REST API discovery spec as source of truth for request/response schemas; fetch documentation index at
ai.google.dev/gemini-api/docs/llms.txt - For real-time bidirectional audio/video streaming, use the separate Gemini Live API skill
