MiMo-V2.6-Flash runs at 62 tok/s (61.7 as recorded) on a 256 GB M5 Ultra, a community run reported by omlx.ai (MLX, 4-bit, 1k context). It needs about 170 GB of unified memory. It is Xiaomi's 309B mixture-of-experts model (15B active), released under the MIT licence.

Each row as the index holds it, with its source. “Mac RAM” is the memory of the Mac a run used, not the model’s requirement (170 GB). The headline figure follows the reference rule: the lower-median measured plain-decode run at 5 bits or fewer (a run whose quant was not stated counts only when no stated-quant run qualifies), else the estimate; a run marked “not used to anchor estimates” is listed here but never becomes the headline.

Ollama — the index has not verified an Ollama tag for MiMo-V2.6-Flash, so it doesn’t print one (a guessed tag fails with “pull model manifest: file does not exist”). Search the Ollama library →

The 62 tok/s figure above came from MLX at 4-bit; other runtimes and quants run at different speeds.

Xiaomi's MIT-licensed 309B MoE with 15B active: text, image, video and audio in, 1M context. The 27 Sep 2026 MOPD checkpoint supersedes the RL release (Terminal-Bench 2.1 87.6 and DeepSWE v1.1 67.9 are RL-checkpoint card figures). The smallest GGUF is 126 GB and 4-bit MLX builds are ~172 GB, so it starts at a 192 GB Mac Studio. A community oMLX 4-bit run measured 61.7 tok/s on an M5 Ultra (256 GB, MTP off), and community MLX runs on an M3 Ultra measured 55–59; all used the RL checkpoint, which has the same architecture as the MOPD checkpoint listed here. The index's earlier M5 Ultra estimate was ~79.
