Vertex AI GenAI Inference

Connect to Vertex AI Generative AI models for inference by using SDKs like the GenAI SDK, OpenAI SDK, or Vertex AI SDK, which require Application Default Credentials for authenticated access.

Yes, you can use the OpenAI SDK to call Llama 3.3 on Google Cloud Vertex AI. The platform supports OpenMaaS offerings including Llama, DeepSeek, and Qwen through multiple compatible SDKs.

Yes, you need Application Default Credentials to run Vertex AI GenAI inference. Authenticated access requires these credentials along with specific model ID verification to ensure successful API calls.

The best way to generate text using Gemini 2.5 Pro through Vertex AI is to use the unified GenAI SDK, which provides consistent interaction for first-party Gemini models and handles text generation tasks efficiently.

Yes, Vertex AI inference supports both chat completions and embeddings for third-party models. It covers multiple interaction patterns for OpenMaaS offerings like Llama, DeepSeek, and Qwen alongside first-party Gemini models.

Your Vertex AI GenAI API call fails with an invalid model ID because successful inference requires specific model ID verification. You must ensure the provided model ID exactly matches the supported Gemini or OpenMaaS offerings.
