Multiverse Computing launches Quasar 438B, Europe's top AI model

Its 15-second response time beats most rivals that score higher, a rare combination for models built to run AI agents.

• Multiverse Computing launched Quasar 438B, a 438-billion-parameter reasoning model that scored 43 on the Artificial Analysis Intelligence Index v4.1.1, the highest mark of any European model tracked.
• The Spanish AI-compression specialist built Quasar as its first large-scale model, extending its CompactifAI efficiency work into the 400B-plus parameter class.
• Quasar returns 500 output tokens in 15.3 seconds, reasoning time included; only three benchmarked models answer faster, and just one of those scores higher.
• It outscores Mistral Medium 3.5 (30) and Nvidia's Nemotron 3 Ultra (38) despite Nemotron carrying 112 billion more parameters, while Claude Opus 5 leads the overall field at 63.
• Built for enterprise agents and coding rather than consumer chat, Quasar targets tasks like software engineering and document-heavy research and is available now via the CompactifAI API.
• The launch signals that European AI developers can pair strong reasoning with fast response times, a combination enterprises need for multi-step agentic workflows without defaulting to US or Chinese models.
