Nebius AI Studio

Install

To use Nebius AI Studio, you need to either install pydantic-ai, or install pydantic-ai-slim with the openai optional group (as it uses an OpenAI-compatible API):

pip install 'pydantic-ai-slim[openai]'

uv add 'pydantic-ai-slim[openai]'

Configuration

Go to Nebius AI Studio and create an API key.

You can set the NEBIUS_API_KEY environment variable and use NebiusProvider by name:

from pydantic_ai import Agent

agent = Agent('nebius:Qwen/Qwen3-32B-fast')
result = agent.run_sync('What is the capital of France?')
print(result.output)
#> The capital of France is Paris.

Or initialise the model and provider directly:

from pydantic_ai import Agent
from pydantic_ai.models.openai import OpenAIChatModel
from pydantic_ai.providers.nebius import NebiusProvider

model = OpenAIChatModel(
    'Qwen/Qwen3-32B-fast',
    provider=NebiusProvider(api_key='your-nebius-api-key'),
)
agent = Agent(model)
result = agent.run_sync('What is the capital of France?')
print(result.output)
#> The capital of France is Paris.
