// RUN — FITS
Can the Apple M4 Max 64GB run Kosmos-2?
Yes — here's how fast and up to what context, with real measured numbers.
Kosmos-2 on the Apple M4 Max 64GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 807k | 116-139.9 t/s | ~2.1-2.6 (slow) |
| Q8 | yes | 832k | 232.1-279.8 t/s | ~4.3-5.1 (slow) |
| Q4 | yes | 842k | 414.4-499.7 t/s | ~7.6-9.2 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
