Yes — here's how fast and up to what context, with real measured numbers.
ESM3-open-small on the Apple M1 Ultra 64GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 813k | 194.3-234.3 t/s | ~2.4-2.9 (slow) |
| Q8 | yes | 835k | 388.6-468.6 t/s | ~4.9-5.9 (slow) |
| Q4 | yes | 844k | 693.9-836.7 t/s | ~8.7-10.5 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
