The Nebius Serverless AI Builders Challenge (the “Challenge”) is organised by Nebius B.V. (“Nebius”) to recognise and reward the ML and AI practitioner community for building, documenting, and publishing reproducible examples using Nebius Serverless Jobs and Serverless Endpoints. The Challenge aims to grow awareness of Nebius Serverless products, produce high-quality practitioner-made content, and support the broader ML and AI community with reusable, open-source examples.

In these Terms and Conditions, the following definitions apply:

“Challenge Period” means the period commencing on the date these Terms and Conditions are published and ending on July 15, 2026, at 23:59 UTC.

“Judge Panel” has the meaning given in Section 7.

“Participant” or “Participants” means any individual or team admitted by Nebius for participation in the Challenge in accordance with Section 1.

“Submission” means a valid entry to the Challenge comprising all required components as set out in Section 3.

“Tenant ID” means the unique identifier associated with a Participant’s Nebius account.

1. Eligibility1. Eligibility

To participate in the Challenge, individuals or teams must meet the following requirements:

a) Be an individual developer, researcher, data scientist, or startup team of up to three (3) members. Both new and existing Nebius customers are eligible, including those already using Nebius Serverless Jobs or Serverless Endpoints.

b) Be 18 years or older.

c) Have access to a Nebius account (free tier is available for new registrations subject to the terms and conditions at Nebius website) and submit at least one Serverless Job or Serverless Endpoint run during the Challenge Period window.

Nebius’s decision in this regard shall be final and binding.

2. Compliance with Sanctions2. Compliance with Sanctions

By participating in the Challenge, Participants warrant that they, their team members, officers, and agents are not subject to any sanctions, embargoes, or other restrictive measures imposed by the United Nations, the European Union, the United States of America, or any other applicable government or regulatory authority.

Nebius reserves the right to verify compliance with these warranties and to refuse or disqualify any Participant if it has reason to believe that the Participant is not in compliance.

3. Submission Requirements3. Submission Requirements

A valid submission must include all of the following components:

a) Code repository — A public GitHub or GitLab repository containing:

• Code that uses or integrates with Nebius Serverless Jobs or Serverless Endpoints.
• A Dockerfile or reference to public Docker images for reproducibility.
• A README file with setup instructions, hardware configuration, expected outputs, and approximate runtime or cost information.
• An open-source license.
• No committed secrets, credentials, private keys, passwords, API tokens, access tokens, production datasets, confidential information, or unnecessary personal data.

b) Technical blog post — A post of at least 600 words, published on Medium, Dev community, a personal blog, Hashnode, or an equivalent public platform, that:

• Links to the code repository.
• Carries the required tag: #NebiusServerlessChallenge.
• Explains the problem, approach, Nebius architecture, implementation, and results.
• Evidenced that the submission runs on Nebius, in the form of screenshots, logs, or benchmark results.

Submissions must be entered via the official competition form on AI Academy before July 15, 2026, at 23:59 UTC. A submission is only valid if all two components are present, publicly accessible, and linked in the submission form.

Each Nebius Tenant ID may submit only one (1) entry to the Challenge. Where multiple submissions are received from the same Tenant ID, only the first valid submission will be considered; subsequent submissions from the same Tenant ID will be rejected

4. Originality and Content Requirements4. Originality and Content Requirements

By participating in the Challenge, Participants warrant that:

a) Their submission is original work, created solely for the purposes of the Challenge (or substantially extended for the Challenge), and has not been previously published in its current form.

b) The blog post contains original narrative content — including problem framing, results, architecture rationale, and lessons learned — and is not a copy or paraphrase of the code repository README.

c) Their submission does not infringe any third-party intellectual property rights, including copyright, trademark, patent, or trade secret rights.

d) Their submission does not contain harmful, offensive, defamatory, or otherwise inappropriate content.

Nebius reserves the right to disqualify any submission that violates these requirements.

5. Evaluation Criteria5. Evaluation Criteria

Each eligible submission will be scored by a domain-specific judge panel, using the following criteria:

Technical Implementation. Code runs end-to-end with no issues. Architecture is well-designed and appropriate for the use case. Nebius Serverless integration is correct, and effective. Code quality is high (readable, documented, no obvious bugs or anti-patterns).

Reproducibility. README is complete: architecture explanation, step-by-step setup, hardware/config specified, expected outputs shown, approximate runtime/cost noted. No committed secrets. Dependencies fully specified (pinned requirements.txt, pyproject.toml, environment.yml, or Dockerfile). Data is publicly available with download instructions, or synthetic data is included. Runs without modification.

Educational Content Quality. Post is well-structured and reads like a practitioner tutorial. Covers problem, approach, Nebius architecture, implementation walkthrough, results, and lessons learned. Technical depth is appropriate — assumes ML background, explains Serverless-specific choices. Writing is clear and concise.

Product Usage Depth. Serverless Jobs or Endpoints are central to the solution. The post explicitly explains why Serverless is a good fit for this use case (vs. alternatives). Non-trivial usage: handles orchestration, checkpoints, retry logic, async patterns, or similar real operational concerns.

Usefulness / Real-World Impact. Solves a clearly articulated real-world problem. The solution is immediately reusable or adaptable by others in the same domain. Has obvious practical value beyond the competition.

Originality / Creativity. Novel approach, domain-specific insight, or creative application of Serverless that hasn’t been done before (or is a meaningful improvement on prior art). Clearly goes beyond following a tutorial.

Individual scores assigned by judges will not be published or disclosed to Participants. Only the final award outcomes — winners, Special Award recipients, Community Choice, and Awesome Serverless Award recipients — will be announced publicly.

6. Automated Eligibility Check6. Automated Eligibility Check

Automated eligibility checks will run on a rolling basis during the submission period. All submissions will be assessed for structural completeness, content safety, topic relevance, and Serverless AI product signal. Submissions that do not pass this check will be notified of the main reason for the outcome, where reasonably possible, and may correct and resubmit their submission before the deadline. Each Participant is permitted a maximum of one (1) resubmission. Nebius may withhold detailed detection logic or security information where disclosure could compromise the integrity, security, or anti-abuse controls of the Challenge.

Automated tools may be used to support eligibility checks, content safety review, topic relevance assessment, Serverless product signal detection, and preliminary scoring. These tools are used to assist the Challenge administration and judging process. Final award decisions are subject to human review and confirmation by Nebius and/or the Judge Panel.

If a submission is rejected or not advanced as a result of an automated eligibility check, the Participant may request human review of the outcome by contacting Nebius at serverlesschallenge@nebius.com.

7. Judge Panel7. Judge Panel

The Challenge will be judged by domain-specific panels (each a “Judge Panel”), consisting of:

b) Representatives from Nebius, providing expertise on Nebius Serverless products and engineering standards.

The Judge Panel is responsible for evaluating submissions and nominating winners in accordance with the published rubric and process. Judge Panel decisions are final subject to confirmation by Nebius.
