This is Qwen3-Next-80B-A3B-Instruct (MLX 4-bit quantization, group size 64)
repacked into the .qpack streaming container for
Swiftlet, a Swift + Metal runtime
that runs large Mixture-of-Experts models on ordinary Apple Silicon by
streaming experts from storage instead of loading them into RAM.
Measured on a base M5 MacBook (24 GB):
| Metric | Value |
|---|---|
| Disk | 42 GB |
| Peak RAM | 4.3 GB (2 GB expert cache) |
| Decode speed | 4.5 to 5.3 tok/s |
| First token | about 5 s on a short prompt |
This model is for Macs. iPhones do not have the storage for it; the phone model is Qwen3.6-35B-A3B-qpack.
