TII's 180B model trained on curated RefinedWeb data.

Unique: Achieves few-shot learning through pure scale (180B parameters) and diverse training data (3.5T tokens) without explicit few-shot fine-tuning, enabling emergent task adaptation across arbitrary domains, though with less predictable performance than models explicitly optimized for in-context learning.

via “zero-shot and few-shot generalization via task diversity”

Google's 1,836-task instruction mixture for broad generalization.
