WILL MY BOX RUN LONGCAT 2.0?
The three cards above are researched picks. Search the machine you actually have — we only say yes if it should reply at a usable speed, not just load the weights and crawl.
HARDWARE PICKS & PRICES ARE RESEARCHED FROM THE LIVE WEB AND REFRESHED AUTOMATICALLY. TREAT THEM AS BALLPARK, NOT GOSPEL.
WHAT CAN YOU ACTUALLY DO WITH IT?
Everyday jobs on each of those rigs: how long LongCat 2.0 takes, and how good the crowd says it is at that kind of work.
| THE JOB | SWEET SPOTDedicated multi-node cluster with 8x NVIDIA A100 80GB PCIe | FULL POWERHGX cluster with 8x NVIDIA H100 80GB SXM5 |

STARS ARE THE COMMUNITY SCORE FOR THAT KIND OF WORK, DOCKED FOR HOW SQUASHED THE WEIGHTS GET AT EACH TIER. TIMES ARE COMPUTED FROM RESEARCHED SPEEDS. BALLPARK, NOT GOSPEL.
