About the hackathon

Get early access to Hafnia's Vision-Language-Model (VLM)-as-a-Service!

The hackathon gives you access to NVIDIA's Cosmos-Reason1-7b model. Your mission:

•Create innovative integrations with XProtect or third-party applications.
•Leverage the VLM to enhance smart city solutions — using video understanding, summarization, and context to complement real-time analytics.
•Build and submit your MVP demo for the chance to pitch live in Copenhagen at the Milestone Developer Summit (Nov 10–11).

What you get

VLM API access - Cosmos-Reason1-7B:

Project Hafnia - Data & Services for Responsible Computer Vision

Project Hafnia is a compliant-first platform combining a curated Data Library with Training-aaS and VLM-aaS to speed computer vision development. Hafnia bridges the gap between data owners and AI developers — turning real-world video into compliant, high-performance training fuel for next-gen analytics. Available soon.

Data Library: Gain access and train your computer vision models on compliantly sourced real-world data. The data is curated, extensively annotated and anonymized.

Training-as-a-Service (TaaS): Train models that outperform others, and pass compliance audits. Simply write your training script, select your data and GPU and receive a new and improved model with metrics that matter!

VLM-as-a-Service (VLM-aaS): Built on NVIDIA's Cosmos-Reason1-7B and fine-tuned on compliantly sourced real-world traffic data for higher accuracy in complex road environment; for this hackathon, you'll use the base Cosmos-Reason1-7B (no fine-tuning).

Judging criteria

Potential Value/Impact

Relevance to Smart City or surveillance use cases, with clear real-world applicability and potential to attract users, partners, or customers.

Creativity

Originality and innovative use of technology to solve practical problems with fresh, unique approaches.

Technological Execution

Strength of architecture and implementation - well-structured, reliable, and technically sound.

Functionality

Solution works as intended, scales effectively, and properly leverages available technology.

Demo Presentation

Clear, high-quality demo with strong overall impression and "wow" factor.

Participation Rules

Entrants must develop an integration of the Hafnia VLM-as-a-Service into a real-world application.

The integration should demonstrate how the VLM API can be used to enhance, for example Smart City, surveillance, or related use cases (e.g., validating real-time alerts with video clips, automating monitoring workflows, or improving decision-making through multimodal inputs).

Participants will receive tokens and access to the VLM API documentation and are expected to build a functional proof-of-concept that showcases a clear use case and value.

Register online before the deadline
Teams of up to 5 members
Original projects only, built during hackathon
