Source freshness Snapshot date: 2026-06-15; official quota and pricing can change without notice.

Python setup snapshot

Start with the smallest possible chat completion, then move the key to your server-side secret manager before production.

from openai import OpenAI

client = OpenAI(
    api_key="your-nebius-api-key",
    base_url="https://api.studio.nebius.com/v1"
)

response = client.chat.completions.create(
    model="meta-llama/Meta-Llama-3.1-8B-Instruct",
    messages=[{"role": "user", "content": "Say hello from Nebius AI Studio."}],
)
print(response.choices[0].message.content)

cURL smoke test

Use this to verify endpoint, auth header, model name, response shape, and quota before adding SDK abstractions.

curl https://api.studio.nebius.com/v1/chat/completions \
  -H "Authorization: Bearer $NEBIUS_AI_STUDIO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "Meta Llama 3.1 / 3.3 Instruct",
    "messages": [{"role": "user", "content": "Hello from yangmao.ai"}]
  }'

Free API and pricing notes

Trial credits / promotional balance may be available; check AI Studio account

Nebius AI Studio provides hosted model APIs and GPU/AI infrastructure routes. Trial credits, model pricing, OpenAI-compatible endpoint behavior, regions, and rate limits are AI Studio dashboard dependent. It is useful when evaluating open-model APIs backed by European cloud/GPU infrastructure.

Access and production risk

Relay or proxy may be needed

Mainland China access is unconfirmed, and European cloud regions may add latency. For China-facing users, test website, console, API, DNS/TLS, and payment flow, and keep OpenLLMAPI, Qwen, SiliconFlow, or DeepInfra as fallbacks.

Decision checklist

Check Nebius AI Studio free credits and rate limits.

Compare same-category providers and Mainland China access needs.

Pick the provider with the clearest no-card/free API path for testing.

Nebius AI Studio production validation table

Use this table before sending real users, scheduled agents, or paid traffic to Nebius AI Studio. The goal is to validate source freshness, quota behavior, regional access, and fallback needs instead of trusting a stale free-credit claim.

Check Pass condition If it fails

Signup and billing state Key creation works and the account can spend the recorded Trial credits / promotional balance may be available; check AI Studio account. Compare Nebius AI Studio alternatives or route through a gateway before inviting users.

First request from target region Proxy, relay, or non-mainland deployment path is documented before launch. Do not ship cron jobs or public demos until latency, DNS, TLS, and auth are repeatable.

Quota, retry, and error shape Rate-limit behavior matches the current Account, model, and plan dependent note or official dashboard values. Cap retries, add request logging, and keep a second route for 429/5xx bursts.

Cost per accepted task Real prompts stay within your target token, query, image-credit, or compute budget. Use cheaper primary routes, caching, shorter prompts, or fallback only after validation failure.
