NOUS RESEARCH — EVOLUTIONARY MODEL MERGING

MODEL TYPE .............. MULTIMODAL LANGUAGE MODEL
ARCHITECTURE ............ QWEN3 (MODIFIED) + COSMOS3 MULTIMODAL HEADS
PARAMETERS .............. 16B
PRECISION ............... BFLOAT16
GENERATION .............. 0 (BASE)
STATUS .................. DARWIN MERGED — READY FOR SFT

OVERVIEW

OMNISENTER BASE 16B IS A DARWIN FAMILY EVOLVED MULTIMODAL MODEL — THE FIRST GENERATION OF THE OMNISENTER LINEAGE. PRODUCED BY FUSING THE REASONING CAPABILITIES OF QWEN3-8B INTO THE MULTIMODAL WORLD MODEL COSMOS3-NANO VIA PER-TENSOR MRI-TRUST FUSION.

THE MODEL PRESERVES ALL OF COSMOS3-NANO'S MULTIMODAL MODALITIES — VISION, AUDIO, VIDEO UNDERSTANDING AND GENERATION — WHILE BLENDING IN QWEN3-8B'S TEXT REASONING STRENGTHS.
