Vertex AI 不支持OpenAI规范调用gemini吗？

[hhh11316166616191]

`import openai
from google.auth import default
import google.auth.transport.requests

TODO(developer): Update and un-comment below lines
project_id = "PROJECT_ID"
location = "global"

Programmatically get an access token
credentials, _ = default(scopes=["https://www.googleapis.com/auth/cloud-platform"])
credentials.refresh(google.auth.transport.requests.Request())

OpenAI Client
client = openai.OpenAI(
base_url=f"https://aiplatform.googleapis.com/v1/projects/{project_id}/locations/{location}/endpoints/openapi",
api_key=credentials.token
)

response = client.chat.completions.create(
model="google/gemini-2.0-flash-001",
messages=[
{"role": "system", "content": "You are a helpful assistant."},
{"role": "user", "content": "Explain to me how AI works"}
]
)

print(response.choices[0].message)`

通过Accesstoken 调用，不支持这种格式吗？
