Supported Providers

  • OpenAI
  • Vertex AI
TrueFoundry supports File APIs compatible with OpenAI and Vertex AI. This guide demonstrates how to set up the client and use file-related endpoints. Setup OpenAI client first - 
from openai import OpenAI

BASE_URL = "https://{controlPlaneUrl}/api/llm"
API_KEY = "your-truefoundry-api-key"

# Configure OpenAI client with TrueFoundry settings
client = OpenAI(
    api_key=API_KEY,
    base_url=BASE_URL,
)

​
Provider Specific Extra Headers

When making requests, you’ll need to specify provider-specific headers based on which LLM provider you’re using:

​
OpenAI Provider Headers

extra_headers = {
    "x-tfy-provider-name": "openai-provider-name"  # name of tfy provider integration
}

​
Vertex AI Provider Headers

extra_headers = {
    "x-tfy-provider-name": "google-provider-name",  # name of tfy provider integration
    "x-tfy-vertex-storage-bucket-name": "your-bucket-name",
    "x-tfy-vertex-region": "your-region",  # e.g., "europe-west4"
    "x-tfy-provider-model": "gemini-2-0-flash"  # or any other supported model
}

​
