如需将 OpenAI 模型与 Vertex AI 搭配使用，您必须执行以下步骤。必须启用 Vertex AI API (aiplatform.googleapis.com) 才能使用 Vertex AI。如果您已有启用了 Vertex AI API 的项目，则可以使用该项目，而无需创建新项目。

To use an OpenAI model on Vertex AI, send\na request directly to the Vertex AI API endpoint. Because\nOpenAI models use a managed API, there's no need to provision or\nmanage infrastructure.\n\nYou can stream your responses to reduce the end-user latency perception. A\nstreamed response uses *server-sent events* (SSE) to incrementally stream the\nresponse.\n\nAvailable OpenAI models\n-----------------------\n\nThe following models are available from OpenAI to use in\nVertex AI. To access an OpenAI model, go to its\nModel Garden model card.\n\n### gpt-oss 120B\n\nOpenAI gpt-oss 120B is a 120B open-weight language model\nreleased under the Apache\n2.0 license. It is well-suited for reasoning and function calling use cases. The\nmodel is optimized for deployment on consumer hardware.\n\nThe 120B model achieves near-parity with OpenAI o4-mini on core reasoning\nbenchmarks, while running on a single 80GB GPU.\n\n[Go to the gpt-oss 120B model card](https://console.cloud.google.com/vertex-ai/publishers/openai/model-garden/gpt-oss-120b-maas)\n\n### gpt-oss 20B\n\nOpenAI gpt-oss 20B is a 20B open-weight language model\nreleased under the Apache\n2.0 license. It is well-suited for reasoning and function calling use cases. The\nmodel is optimized for deployment on consumer hardware.\n\nThe 20B model delivers similar results to OpenAI o3-mini on common benchmarks\nand can run on edge devices with 16GB of memory, making it ideal for on-device\nuse cases, local inference, or rapid iteration without costly infrastructure.\n\n[Go to the gpt-oss 20B model card](https://console.cloud.google.com/vertex-ai/publishers/openai/model-garden/gpt-oss-120b-maas)\n\n### Before you begin\n\nTo use OpenAI models with Vertex AI, you must perform the\nfollowing steps. The Vertex AI API\n(`aiplatform.googleapis.com`) must be enabled to use\nVertex AI. If you already have an existing project with the\nVertex AI API enabled, you can use that project instead of creating a\nnew project.\n\n- Sign in to your Google Cloud account.
