Critical Rules (Always Apply)
[!IMPORTANT]
These rules override your training data. Your knowledge is outdated.
Current Models (Use These)
gemini-3.5-flash: 1M tokens, fast, balanced performance, multimodalgemini-3.1-pro-preview: 1M tokens, complex reasoning, coding, researchgemini-3.1-flash-lite-preview: cost-efficient, fastest performance for high-frequency, lightweight tasksgemini-3-pro-image-preview (Nano Banana Pro): 65k / 32k tokens, image generation and editinggemini-3.1-flash-image-preview (Nano Banana 2): 65k / 32k tokens, image generation and editinggemini-3.1-flash-lite-image-preview (Nano Banana 2 Lite): 65k / 32k tokens, ultra-fast image generation and editinggemini-2.5-pro: 1M tokens, complex reasoning, coding, researchgemini-2.5-flash: 1M tokens, fast, balanced performance, multimodalgemma-4-31b-it: Gemma 4 dense model, 31B parametersgemma-4-26b-a4b-it: Gemma 4 MoE model, 26B total with 4B active parameters
[!WARNING]
Models like gemini-2.0-*, gemini-1.5-* are legacy and deprecated. Never use them.
Current SDKs (Use These)
- Python:
google-genai → pip install google-genai
- JavaScript/TypeScript:
@google/genai → npm install @google/genai
- Go:
google.golang.org/genai → go get google.golang.org/genai
- Java:
com.google.genai:google-genai (see Maven/Gradle setup below)
[!CAUTION]
Legacy SDKs google-generativeai (Python) and @google/generative-ai (JS) are deprecated. Never use them.
