Rank is the position among all 152 coding models, free and paid. Memory is our estimate for the 4-bit file plus a small working margin.
Which of these you can run at home
Five of the twelve fit fully on one home machine. Qwen3.8-27B is the only one that runs on a single gaming card: it needs about 20 GB, so an RX 7900 XT or any bigger card holds it.
A Mac Studio M3 Ultra with 512 GB holds four more: MiMo-V2.6-Flash (about 191 GB), GLM-5.3-Flash (about 197 GB), MiniMax-M3.1-Flash (about 136 GB) and Qwen3.8-Flash-Next (about 112 GB). No smaller machine on our list has enough memory for them.
Kimi K3 (Max), MiMo-V2.6-Pro, GLM-5.3 (Max) and GLM-5.2 (Max) need more memory than any single home machine on our list. DeepSeek-V4.1-Flash (both versions) and Hy4 preview have no public size, so we cannot say which machine runs them.
