I can find four different Go SDKs
What are the differences between the different Go SDKs and why can I not use the “genai package - google.golang.org/genai - Go Packages” SDK to obtain a list of models?
Hi @John_Cheng ,
Welcome to the Forum !!
Sorry for the late response !
why can I not use the “genai package - google.golang.org/genai - Go Packages” SDK to obtain a list of models?
Ans- The primary reason is the design philosophy of this SDK as an abstraction layer.
Differences:
| Import Path | Primary Target | Authentication | Scope | Recommendation |
|---|---|---|---|---|
| google/generative-ai-go | Google AI Gemini API | API Key | Direct Gemini API | Use if API Key is mandatory, less GCP integration needed. |
| cloud.google.com/go/vertexai/genai | Vertex AI GenAI | GCP Auth (ADC, etc.) | GenAI via Vertex AI | Use if exclusively working with models deployed on Vertex AI within GCP. Note: cloud.google.com/go/genai is the newer approach. |
| genai package - google.golang.org/genai - Go Packages | Google AI or Vertex AI | API Key or GCP Auth | Unified client for both | Recommended for new development due to flexibility and being the latest unified client. |
| cloud.google.com/go/ai | Other GCP AI Services | GCP Auth | Various (often non-gen AI) | Not for accessing modern generative models like Gemini/PaLM. |
Thank you!!
