MeluXina-AI is an AI-optimised supercomputer procured by the EuroHPC Joint Undertaking and Luxembourg for the Luxembourg AI Factory. It will have 252 nodes with 1,008 NVIDIA GPUs and be operated by LuxProvide at Bissen and Bettembourg.

When will MeluXina-AI be operational?

The supply contract was signed on 22 July 2026 and installation is due to start in autumn 2026. In April 2026 Luxinnovation expected go-live at the end of 2026; no confirmed production date had been published as of 6 October 2026.

Is access free for startups and SMEs?

Computing time granted through EuroHPC AI Factory access calls is free of charge, and the Luxembourg AI Factory offers free customised support to SMEs and startups. Commercial use of LuxProvide systems is contracted directly, with programmes such as INITIATE and CASHBACK80 reducing the cost.

Can public administrations use the Luxembourg AI Factory?

Yes. Luxinnovation describes the AI Factory as open to all economic players, including companies, startups, administrations and research organisations.

Who runs the Luxembourg AI Factory?

A consortium of LuxProvide, Luxinnovation, the Luxembourg National Data Service, the University of Luxembourg and LIST, with Luxinnovation as the single entry point and LuxProvide operating the computing infrastructure.

MeluXina-AI and the Luxembourg AI Factory: status in 2026 and how to get access

MeluXina-AI is the AI supercomputer of the Luxembourg AI Factory, contracted on 22 July 2026. Here is what it offers and how firms and public bodies get access.

MeluXina-AI is the AI-optimised supercomputer at the centre of the Luxembourg AI Factory, which the EuroHPC Joint Undertaking selected on 10 December 2024 and which LuxProvide will operate at Bissen and Bettembourg. The EUR 80 million supply contract was signed on 22 July 2026 and installation is due to start in autumn 2026. The AI Factory’s support services, with Luxinnovation as the single entry point, are already open to companies, startups, researchers and public administrations in Luxembourg.

What the Luxembourg AI Factory is

On 10 December 2024 the EuroHPC Joint Undertaking selected the first seven European AI Factories, in Finland, Germany, Greece, Italy, Luxembourg, Spain and Sweden. Luxembourg’s site is Bissen, next to the existing MeluXina supercomputer, with LuxProvide as hosting entity.

An AI Factory is more than a computer. It combines AI-optimised computing with advice, training, data services and links to funding. The Luxembourg consortium consists of LuxProvide, Luxinnovation, the Luxembourg National Data Service (LNDS), the University of Luxembourg and the Luxembourg Institute of Science and Technology (LIST). Associated partners listed on aifactory.lu are the Luxembourg Space Agency, the Luxembourg House of Cybersecurity, Technoport, DEEP, the LHoFT, the Digital Learning Hub and Clarence.

The declared focus sectors are finance, space, cybersecurity and the green economy. According to Luxinnovation, the aim is to help all economic players adopt AI within a “sovereign, responsible, secure and compliant” framework.

Source: EuroHPC JU, 22 July 2026.

The system is designed for GPU-as-a-Service for several tenants at once, with container-based isolation, and for connections to external data platforms, cloud providers and other EuroHPC AI Factories. The AI Factory states that MeluXina-AI will be hosted in Tier IV data centres.

Status as of October 2026

The service side is running. On 30 April 2026 Luxinnovation reported that the AI Factory had been operational since 2025, offered 66 services in seven categories and had supported more than 150 companies, mostly SMEs. At that point it expected MeluXina-AI to go live at the end of 2026.

The hardware is not yet in production. The EuroHPC JU announcement of 22 July 2026 gives autumn 2026 as the start of installation. As of 6 October 2026 no confirmed date for production use had been published. Until then, the AI Factory points users to the existing MeluXina supercomputer, which is already available for AI workloads.

Funding

Paperjam reported a total budget of EUR 126 million: EUR 112 million for MeluXina-AI (EUR 80 million for acquisition and EUR 32 million for five years of operation) and EUR 14 million for the AI Factory over three years, with the EuroHPC JU covering half. The aifactory.lu website also cites EUR 126 million. Figures of EUR 80 million in other sources refer to the hardware contract only.

What organisations can use

The AI Factory groups its offer into six service lines: Assess & Accelerate, Upskill & Train, Connect, Fund, Build & Test, and Scale & Run. For MeluXina-AI it lists training of custom AI models, fine-tuning on private datasets, integration with data lakes and cloud services, and AI-as-a-Service for organisations at the start of their AI adoption, with support from LuxProvide engineers.

Public bodies are explicitly in scope. Luxinnovation names administrations and research organisations alongside companies and startups as target users. The participation of LNDS in the consortium links the AI Factory to the national framework for reusing public sector data.

Access routes and support programmes

Route	For whom	Main terms
AI Factory one-stop shop	Companies, startups, administrations, research	Entry via Luxinnovation; free customised support for SMEs and startups, according to EuroHPC JU
EuroHPC AI Factories access calls	Users from EU Member States and associated countries	Playground (access within two working days), Fast Lane, Large Scale (more than 50,000 GPU hours for up to one year), AI for Science; free of charge, with acknowledgement and reporting duties
LuxProvide INITIATE	Startups founded within the last five years	Free MeluXina credits for up to six months, subject to hardware availability
LuxProvide CASHBACK80	SMEs	Up to 80% cashback on MeluXina usage, via a state-aid request to the Ministry of the Economy with Luxinnovation’s help
Fit 4 AI	Businesses with a Luxembourg business permit and registered office	50% (SMEs) or 30% (large firms) of eligible costs of EUR 10,000 to 200,000 excl. VAT for an analysis by an approved consultant
SME Package AI	SMEs	Up to 70% of eligible costs of EUR 3,000 to 25,000 excl. VAT; pre-analysis by the House of Entrepreneurship or the Chambre des Métiers’ eHandwierk service

Two points need care. Fit 4 AI applications must be filed via MyGuichet.lu before the analysis starts. And the published EuroHPC access-call pages do not yet state when MeluXina-AI capacity will be offered through these calls.

Costs

As of 6 October 2026, neither LuxProvide nor the AI Factory had published a price list for MeluXina-AI. Time granted through EuroHPC access calls is free; commercial use of LuxProvide systems is agreed directly with LuxProvide, and the programmes above reduce the cost for eligible startups and SMEs.

What to do now

Define one concrete use case and the data it needs, including whether personal or confidential data is involved.
Contact the AI Factory via aifactory.lu for an initial assessment and a referral to the right service line.
If the company is a startup or SME, check eligibility for INITIATE, CASHBACK80, Fit 4 AI or the SME Package AI before signing any contract or quote.
For larger training runs, compare the EuroHPC access-call modes and their deadlines.
Plan on the existing MeluXina system for 2026 and treat the move to MeluXina-AI as a later step.
