TRIMELMlong (150M) on the Apple M1 Ultra 128GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1730k | 1813.3-2186.7 t/s | ~22.7-27.3 (slow) |
| Q8 | yes | 1733k | 3626.7-4373.3 t/s | ~45.3-54.7 (slow) |
| Q4 | yes | 1734k | 6476.2-7809.5 t/s | ~81-97.6 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
