LongCat-2.0, a mixture-of-experts AI model boasting 1.6 trillion parameters, has recently come to light after spending two months under the guise of 'Owl Alpha.'
This model was discovered by Meituan, which has since claimed it as its own. Its emergence has raised eyebrows in the AI community.
Notably, LongCat-2.0 is positioned as a cost-effective alternative to other leading models, specifically GPT-5.5 and Claude Sonnet 5, significantly undercutting their pricing.
