Nebius AI Studio Inference Service

What is Nebius AI Studio Inference Service?

Nebius AI Studio Inference Service is a powerful platform designed to help developers and enterprises run state-of-the-art open-source AI models with enterprise-grade performance. Launched as a key product from Nebius, it simplifies the deployment of large language models (LLMs) for inference tasks, eliminating the need for complex MLOps setups. Whether you're building AI applications, prototypes, or scaling to production, this service provides endpoints for popular models like Meta's Llama series, DeepSeek-R1, and Mistral variants, ensuring high accuracy, low latency, and cost efficiency.

At its core, the service hosts these models on optimized infrastructure located in Europe (Finland), leveraging a highly efficient serving pipeline. This setup guarantees ultra-low latency, especially for time-to-first-token responses, making it suitable for real-time applications such as chatbots, RAG (Retrieval-Augmented Generation), and contextual AI scenarios. Users benefit from unlimited scalability, meaning you can transition from initial testing to high-volume production without performance bottlenecks or hidden limits.

How Does Nebius AI Studio Inference Service Work?

The service operates through a straightforward API that's compatible with familiar libraries like OpenAI's SDK, making integration seamless for developers already using similar tools. To get started, sign up for free credits and access the Playground—a user-friendly web interface for testing models without coding. From there, you can switch to API calls for programmatic use.

Here's a basic example of how to interact with it using Python:

import openai
import os

client = openai.OpenAI(
    api_key=os.environ.get("NEBIUS_API_KEY"),
    base_url='https://api.studio.nebius.com/v1'
)

completion = client.chat.completions.create(
    messages=[{'role': 'user', 'content': 'What is the answer to all questions?'}],
    model='meta-llama/Meta-Llama-3.1-8B-Instruct-fast'
)

This code snippet demonstrates querying a model like Meta-Llama-3.1-8B-Instruct in 'fast' mode, delivering quick responses. The service supports two flavors: 'fast' for speed-critical tasks at a premium price, and 'base' for economical processing ideal for bulk workloads. All models undergo rigorous testing to verify quality, ensuring outputs rival proprietary models like GPT-4o in benchmarks for Llama-405B, with up to 3x savings on input tokens.

Data security is a priority, with servers in Finland adhering to strict European regulations. No data leaves the infrastructure unnecessarily, and users can request dedicated instances for enhanced isolation via the self-service console or support team.
