GoKawiilMultiverse Computing's Quasar 438B tops European AI models on intelligence index
Multiverse Computing has launched Quasar 438B, a reasoning model for enterprise agents and coding that operates in English and Spanish. It scored 43 on the Artificial Analysis Intelligence Index, the highest mark of any European model, surpassing Mistral Medium 3.5, NVIDIA Nemotron 3 Ultra and Inkling, though still trailing global leader Claude Opus 5 at 63. It also responds quickly, generating 500 tokens including reasoning time in 15.3 seconds, and is accessible via the CompactifAI API.
GoKawiil's interpretation of the reporting above, not reported fact.
Most models that combine high reasoning scores with large parameter counts tend to be slow, but Quasar pairs a large 400B-plus architecture with response times competitive with much smaller, faster systems. This matters for enterprises needing multi-step reasoning, tool use and code execution without the usual latency penalty, and signals that European AI development can compete on efficiency even without matching the raw scores of leading US labs.
- Quasar 438B scores 43 on the Artificial Analysis Intelligence Index, the top result among European models.
- It balances size and speed, answering in 15.3 seconds despite being a 400B-plus parameter model.
- The model is accessible through the CompactifAI API, letting teams test it without building infrastructure.
