Migrate from OpenAI

Venice AI is a drop-in replacement for OpenAI. Same SDK, same code — just change two lines. Get privacy-first inference, uncensored models, and competitive pricing.

The 2-Line Migration

# Before (OpenAI)
from openai import OpenAI
client = OpenAI()

# After (Venice) — change api_key and base_url
from openai import OpenAI
client = OpenAI(
    api_key="your-venice-api-key",           # ← Change 1
    base_url="https://api.venice.ai/api/v1",  # ← Change 2
)

// Before (OpenAI)
import OpenAI from "openai";
const client = new OpenAI();

// After (Venice)
import OpenAI from "openai";
const client = new OpenAI({
  apiKey: "your-venice-api-key",
  baseURL: "https://api.venice.ai/api/v1",
});

# Before
curl https://api.openai.com/v1/chat/completions ...

# After — just change the URL and key
curl https://api.venice.ai/api/v1/chat/completions ...

Generate a key from venice.ai/settings/api or follow the API key guide.

Environment variables

# Before
OPENAI_API_KEY=sk-...
OPENAI_BASE_URL=https://api.openai.com/v1

# After
OPENAI_API_KEY=your-venice-api-key
OPENAI_BASE_URL=https://api.venice.ai/api/v1

Many libraries and tools read OPENAI_API_KEY and OPENAI_BASE_URL automatically. Updating these env vars may be all you need. Some tools still use OPENAI_API_BASE for the same URL.

Models

Pass a Venice model ID, a trait such as default or most_uncensored, or a familiar OpenAI-style name. Venice maps OpenAI names through compatibility mapping. Traits always resolve to the current model for that role — see model traits. Browse the live catalog on Text models and Pricing. For a first-request walkthrough, see the Quickstart.

Feature compatibility

Feature	OpenAI	Venice	Notes
Chat Completions	✅	✅	Fully compatible
Streaming	✅	✅	Same SSE format
Function Calling	✅	✅	Same `tools` parameter
Structured Output	✅	✅	Same `response_format`
Vision	✅	✅	Same content array format
Embeddings	✅	✅	Same API
Image Generation	✅	✅	OpenAI-compatible via `/images/generations`
TTS	✅	✅	Compatible
STT	✅	✅	Compatible
Responses API	✅	✅	Alpha
Assistants API	✅	❌	Use Characters or function calling
Batch API	✅	❌	Not yet available
Fine-tuning	✅	❌	Not available

For native image options beyond the OpenAI-compatible endpoint, see Image generation.

Venice-only features

Pass Venice-specific options through extra_body as venice_parameters. Built-in web search is the usual first extra:

response = client.chat.completions.create(
    model="default",
    messages=[{"role": "user", "content": "Latest AI news today"}],
    extra_body={
        "venice_parameters": {
            "enable_web_search": "auto"
        }
    },
)

The same pattern covers web scraping, citations, and Characters. If a client cannot change the request body, append a model feature suffix such as default:enable_web_search=auto. Venice also has native video, music, web retrieval, and x402 APIs alongside the OpenAI-compatible surface.

Frameworks

Most AI frameworks work with Venice by changing the base URL:

LangChain

base_url in ChatOpenAI

Vercel AI SDK

baseURL in createOpenAI

LlamaIndex

api_base on the OpenAI-compatible client

CrewAI

OPENAI_API_BASE env var

PydanticAI

OpenAI-compatible model with Venice base URL

Cursor

Custom API endpoint in settings

Claude Code

Route Claude Code through Venice

Codex CLI

config.toml model provider

Aider

OPENAI_API_BASE env var

More coding agents and tools are listed in AI Agents.

Uncensored models

Venice’s private uncensored models have no content filtering, making them suitable for:

Creative writing without guardrails
Security research and red teaming
Honest analysis without refusal patterns
Medical and legal information without extra disclaimers

Use the most_uncensored trait or a current uncensored model ID from Text models.
