Can the Apple M1 Ultra 64GB run BiomedGPT (182M)?
Yes — here's how fast and up to what context, with real measured numbers.
BiomedGPT (182M) on the Apple M1 Ultra 64GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 850k | 1494.5-1802.2 t/s | ~18.7-22.5 (slow) |
| Q8 | yes | 853k | 2989-3604.4 t/s | ~37.4-45.1 (slow) |
| Q4 | yes | 854k | 5337.5-6436.4 t/s | ~66.7-80.5 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
