Large Language Models Face a Size Crisis—This Startup’s Quantum-Inspired Solution Could Be the Answer

In the rapidly evolving world of artificial intelligence, one problem is becoming increasingly apparent: large language models (LLMs) are, well, too large. These behemoths of the AI world require enormous computational resources, massive amounts of memory, and consequently, hefty price tags that put them out of reach for many organizations. Enter Multiverse Computing, a Spanish startup that’s tackling this challenge head-on with a revolutionary approach that could democratize access to powerful AI capabilities.

The Problem with Size: Why Big Models Are Breaking Budgets

Large language models have transformed what’s possible in natural language processing, but their size comes with significant drawbacks. Training and deploying models like GPT-4 or Claude requires specialized hardware, often costing millions of dollars. Even for companies that can afford the infrastructure, the operational costs of running these models at scale can be prohibitive.

The issue isn’t just about money—it’s about accessibility. When only tech giants can afford to deploy cutting-edge AI, innovation stagnates, and smaller players are left behind. This creates a concerning centralization of AI power that could have far-reaching implications for competition, privacy, and technological sovereignty.

Quantum-Inspired Compression: The Secret Sauce

Multiverse Computing’s solution, CompactifAI, represents a paradigm shift in how we think about AI model deployment. Rather than building bigger models, they’re making existing models smaller—without sacrificing performance. The technology draws inspiration from quantum computing principles, using sophisticated mathematical techniques to compress models while preserving their core capabilities.

The results are impressive. Their HyperNova 60B model, now available for free on Hugging Face, is approximately half the size of its source model (OpenAI’s gpt-oss-120b) at just 32GB, yet maintains comparable performance. This means companies can run sophisticated AI applications on standard hardware, dramatically reducing infrastructure costs.

Performance That Punches Above Its Weight

Don’t let the smaller size fool you—HyperNova 60B delivers where it counts. The model boasts lower memory usage and reduced latency compared to its larger counterparts, making it ideal for real-time applications. The latest version, HyperNova 60B 2602, released in February 2026, adds enhanced support for tool calling and agentic coding—features that are becoming increasingly important as AI systems take on more complex, autonomous tasks.

Perhaps most impressively, Multiverse claims their model outperforms Mistral Large 3, one of the flagship offerings from French AI company Mistral AI. In the competitive landscape of European AI, this represents a significant achievement and validates their compression approach.

European AI Rising: The Multiverse-Mistral Parallel

The story of Multiverse Computing mirrors that of Mistral AI in fascinating ways. Both companies have roots in Europe but have expanded globally, with offices across the United States, Canada, and Europe. Both serve enterprise customers—Multiverse counts Iberdrola, Bosch, and the Bank of Canada among its clients, while Mistral has built its own impressive roster.

This parallel growth reflects a broader trend: European AI companies are no longer content to play second fiddle to American tech giants. They’re building alternatives that emphasize sovereignty, data privacy, and regional control—values that resonate strongly in Europe’s regulatory environment.

Unicorn Rumors and Funding Frenzy

If reports are accurate, Multiverse Computing is on the cusp of achieving unicorn status, with rumors circulating about a potential €500 million funding round at a valuation exceeding €1.5 billion. While the company hasn’t confirmed these specifics, they acknowledge active discussions with potential investors.

This potential valuation would place Multiverse among Europe’s AI elite, though it would still represent only a fraction of OpenAI’s reported $20 billion annual recurring revenue. However, the trajectory is clear: European AI companies are gaining momentum, and Multiverse is at the forefront of this movement.

Geopolitical Undertones: AI Sovereignty in the Spotlight

Beyond the technological achievements, Multiverse’s story is deeply intertwined with questions of technological sovereignty. In an era where AI capabilities are increasingly seen as matters of national and regional importance, having European alternatives to American tech giants has become a strategic priority.

This geopolitical dimension recently helped Multiverse secure a collaboration with the regional government of Aragón in northeastern Spain. The Spanish Agency for Technological Transformation (SETT) also participated in the company’s $215 million Series B funding round last year, demonstrating strong government support for domestic AI development.

The Basque Advantage: Regional Support for Innovation

Multiverse’s success story is also a testament to the power of regional innovation ecosystems. Since its inception, the company has benefited from support from the Basque region, known for its strong industrial base and commitment to technological advancement. This backing has helped Multiverse build the expertise and credibility needed to compete on the global stage.

If Multiverse achieves unicorn status, it would mark the Basque region’s first technology unicorn—a significant milestone that could catalyze further innovation in the area and demonstrate the viability of European AI companies on the world stage.

What This Means for the Future of AI

Multiverse Computing’s approach represents more than just a clever technical solution—it points toward a future where AI capabilities are more accessible, more affordable, and more widely distributed. By solving the size problem, they’re addressing one of the fundamental barriers to AI adoption.

The implications are far-reaching. Smaller companies can now deploy sophisticated AI without massive infrastructure investments. Developers in regions with limited resources gain access to cutting-edge capabilities. And the centralization of AI power becomes less pronounced, potentially leading to more diverse and innovative applications.

Looking Ahead: Open Source and Beyond

Multiverse’s commitment to open-sourcing more compressed models in 2026 signals an important shift in the AI landscape. By making these technologies freely available, they’re not just building a business—they’re contributing to a more open, accessible AI ecosystem.

As the company continues to refine its compression technology and expand its model offerings, we can expect to see even more impressive performance from increasingly compact models. The days of AI being limited by size constraints may be numbered, thanks to innovations like CompactifAI.
