Query AI Gateway endpoints

Beta

This feature is in Beta. Account admins can control access to this feature from the account console Previews page. See Manage Databricks previews.

This page describes how to query AI Gateway (Beta) endpoints using supported APIs.

Requirements​

Supported APIs and integrations​

AI Gateway supports the following APIs and integrations:

Query endpoints with unified APIs​

Unified APIs offer an OpenAI-compatible interface to query models on Databricks. Use unified APIs to seamlessly switch between models from different providers without changing your code.

MLflow Chat Completions API​

Python
from openai import OpenAI
import os

DATABRICKS_TOKEN = os.environ.get('DATABRICKS_TOKEN')

client = OpenAI(
  api_key=DATABRICKS_TOKEN,
  base_url="https://<ai-gateway-url>/mlflow/v1"
)

chat_completion = client.chat.completions.create(
  messages=[
    {"role": "user", "content": "Hello!"},
    {"role": "assistant", "content": "Hello! How can I assist you today?"},
    {"role": "user", "content": "What is Databricks?"},
  ],
  model="<ai-gateway-endpoint>",
  max_tokens=256
)

print(chat_completion.choices[0].message.content)

Replace <ai-gateway-url> with your AI Gateway URL and <ai-gateway-endpoint> with your AI Gateway endpoint name.

MLflow Embeddings API​

Python
from openai import OpenAI
import os

DATABRICKS_TOKEN = os.environ.get('DATABRICKS_TOKEN')

client = OpenAI(
  api_key=DATABRICKS_TOKEN,
  base_url="https://<ai-gateway-url>/mlflow/v1"
)

embeddings = client.embeddings.create(
  input="What is Databricks?",
  model="<ai-gateway-endpoint>"
)

print(embeddings.data[0].embedding)

Replace <ai-gateway-url> with your AI Gateway URL and <ai-gateway-endpoint> with your AI Gateway endpoint name.

Query endpoints with native APIs​

Native APIs offer provider-specific interfaces to query models on Databricks. Use native APIs to access the latest provider-specific features.

OpenAI Responses API​

Python
from openai import OpenAI
import os

DATABRICKS_TOKEN = os.environ.get('DATABRICKS_TOKEN')

client = OpenAI(
  api_key=DATABRICKS_TOKEN,
  base_url="https://<ai-gateway-url>/openai/v1"
)

response = client.responses.create(
  model="<ai-gateway-endpoint>",
  max_output_tokens=256,
  input=[
    {
      "role": "user",
      "content": [{"type": "input_text", "text": "Hello!"}]
    },
    {
      "role": "assistant",
      "content": [{"type": "output_text", "text": "Hello! How can I assist you today?"}]
    },
    {
      "role": "user",
      "content": [{"type": "input_text", "text": "What is Databricks?"}]
    }
  ]
)

print(response.output)

Replace <ai-gateway-url> with your AI Gateway URL and <ai-gateway-endpoint> with your AI Gateway endpoint name.

Anthropic Messages API​

Python
import anthropic
import os

DATABRICKS_TOKEN = os.environ.get('DATABRICKS_TOKEN')

client = anthropic.Anthropic(
  api_key="unused",
  base_url="https://<ai-gateway-url>/anthropic",
  default_headers={
    "Authorization": f"Bearer {DATABRICKS_TOKEN}",
  },
)

message = client.messages.create(
  model="<ai-gateway-endpoint>",
  max_tokens=256,
  messages=[
    {"role": "user", "content": "Hello!"},
    {"role": "assistant", "content": "Hello! How can I assist you today?"},
    {"role": "user", "content": "What is Databricks?"},
  ],
)

print(message.content[0].text)

Replace <ai-gateway-url> with your AI Gateway URL and <ai-gateway-endpoint> with your AI Gateway endpoint name.

Gemini API​

Python
from google import genai
from google.genai import types
import os

DATABRICKS_TOKEN = os.environ.get('DATABRICKS_TOKEN')

client = genai.Client(
  api_key="databricks",
  http_options=types.HttpOptions(
    base_url="https://<ai-gateway-url>/gemini",
    headers={
      "Authorization": f"Bearer {DATABRICKS_TOKEN}",
    },
  ),
)

response = client.models.generate_content(
  model="<ai-gateway-endpoint>",
  contents=[
    types.Content(
      role="user",
      parts=[types.Part(text="Hello!")],
    ),
    types.Content(
      role="model",
      parts=[types.Part(text="Hello! How can I assist you today?")],
    ),
    types.Content(
      role="user",
      parts=[types.Part(text="What is Databricks?")],
    ),
  ],
  config=types.GenerateContentConfig(
    max_output_tokens=256,
  ),
)

print(response.text)

Replace <ai-gateway-url> with your AI Gateway URL and <ai-gateway-endpoint> with your AI Gateway endpoint name.
