Nebius AI Cloud & GPU Infrastructure

Nebius provides a cloud platform purpose-built for AI/ML workloads and high-performance compute.

  • AI-native cloud platform launched in October 2024, built from scratch to support full ML lifecycle (data preprocessing, training, fine-tuning, inference) using NVIDIA accelerated compute.
  • GPU-hardware: users can get access to NVIDIA H100, H200, L40S GPUs, the upcoming GB200 NVL72 platform, and Blackwell Ultra.
  • Scalable compute: supports large clusters, managed Kubernetes or Slurm orchestration, fast storage, interconnects (InfiniBand) etc.
  • Security & enterprise readiness: encryption, secure infrastructure, API / CLI / infrastructure-as-code tools, console UI.

Nebius AI Studio (Inference / Model Access)

Tooling for model deployment, inference, and open-source models:

  • AI Studio is Nebius’s inference service offering low-latency, cost-efficient endpoints. It supports open-source LLMs (such as Llama, Mistral, Nemo, Qwen, etc.).
  • Performance: claimed up to ~4.5× faster than competitors, with pricing up to ~50% cheaper.
  • Flexible pricing: premium / high-speed vs cost-efficient endpoints.
  • Rapid scaling: designed to go from experiment / prototype to large production workload.

Major Highlights & Strategic Moves

  • In September 2025, Nebius signed a US$17.4 billion multi-year agreement with Microsoft, to provide AI infrastructure over five years; could rise to ~$19.4B depending on capacity / services.

  • Nebius is raising US$3 billion to accelerate growth: with $2 billion via convertible notes, $1 billion via public offering. These funds will go toward hardware, more data centers, securing land, expanding footprint.

  • Global expansion: deploying GPU clusters / data centers in UK (Blackwell Ultra GPUs), US (Vineland, New Jersey data center), Europe (Finland, France), among others.

Additional Notes

  • Nebius originated from a spinoff / restructuring of Yandex: after divesting the Russian operations under Yandex, the company refocused on international AI infrastructure.
  • It is publicly traded (Nasdaq: NBIS) and is positioning itself among competitors in AI infrastructure / “neocloud” category.
  • Competitive differentiation includes: vertical integration (hardware, data centres, software stack), open-source model support, and cost-performance trade-offs in inference.

Secure-AI

Secure-AI

LLMs have recently adopted persistent memory to provide models with better user knowledge and personalisation. However, this introduces a new vector for adversarial manipulation. This report investigates Memory Injection, a threat model where adversaries exploit indirect prompt injection within web content to poison an agent's long-term memory. Employing user manipulation scenarios, we show that memory attacks, should they succeed, are effective at changing model behaviour towards the user, often more so than a direct system prompt. Hence, this highlights the need for more robust evaluations of memory updates in agentic memory systems.

CO2 Emission Reduction Analyzer

CO2 Emission Reduction Analyzer

Climate change is one of the most pressing challenges of our time, with carbon emissions being a primary contributor. However, analyzing carbon emissions data and developing effective mitigation strategies requires. Climate change is one of the most pressing challenges of our time, with carbon emissions being a primary contributor. However, analyzing carbon emissions data and developing effective mitigation strategies requires. We developed an AI Agentic Carbon Emissions Analyzer that uses a multi-agent system powered by Coral Protocol to provide comprehensive climate analysis and actionable recommendations. Our research revealed that 73% of climate initiatives fail due to lack of coordination. rontend: Streamlit with custom CSS and responsive design Visualization: Plotly for interactive charts (bar, pie, line, area) Data Processing: Pandas, NumPy for data manipulation AI Integration: Mistral AI API for intelligent analysis Agent Communication: Coral Protocol MCP standard Blockchain: Crossmint for decentralized storage This isn't just an app - it's a paradigm shift. Governments can make informed policy decisions in minutes. Businesses can optimize their carbon strategies instantly. Communities can plan local climate actions with AI-powered insights. We're democratizing climate intelligence, making advanced climate analysis accessible to everyone, from small communities to global organizations. Because climate action can't wait for bureaucracy.

Compliance Copilot

Compliance Copilot

ComplianceCopilot transforms the tedious and error-prone process of document compliance review into an automated, AI-driven workflow. Users can upload documents, and the platform leverages multiple AI agents to: 1. Analyze content for regulatory and internal compliance risks. 2. Summarize key information for faster decision-making. 3. Flag potential issues with actionable recommendations. The platform features a rental-based agent system, allowing companies to “rent” AI review agents for a limited time, tracked via a secure token system. This model ensures cost efficiency while maintaining flexibility for varying workloads. A real-time dashboard displays live logs, verification status, and remaining rental time, providing transparency and control. By combining automation, AI, and a secure rental workflow, ComplianceCopilot helps organizations reduce compliance costs, accelerate audits, and mitigate risk more effectively.

Your 2 Minute Daily Reflection Companion

Your 2 Minute Daily Reflection Companion

Reflecta is a digital life coach created to help overwhelmed people with stress and anxiety build emotional awareness and balance for just a few spare minutes throughout the day. Giving the user just an easy evening experience, a gentle notification is issued, prompting the user to enter into a brief 3-to-5-question dialogue with the AI. The chatting can be text or voice-based, focusing on positive highlights, challenges, self-appreciation, and slight improvements. Then, AI churns out an empathetic, gentle reflection that gently points out patterns and suggestions: maybe introduce quiet hours, take note of recurring stressors, or recognize sources of joy. In an easy-to-understand visualization, users can track their "emotional map of the day," along with weekly summaries that offer further insights regarding their habits, moods, and well-being. In contrast to most productivity tools, Reflecta is aimed at care and empathy—allowing users a safe, non-judgmental space to check in with themselves. It is geared towards professionals, students, freelancers, and/or parents needing mindful pauses through the chaos. Reflecta's mission is to imbue resilience by turning two minutes of mindful reflection into a valuable daily ritual.
