●From the file◐Predictedwhat these mean

Speed is modeled, not measured: decode is memory-bandwidth bound, so tokens per second is bytes read per token against achievable bandwidth. Mixture-of-experts models carry a wider band because only the routed experts are read each step, and few have been measured publicly.

Questions people ask

What AI models can a Apple M1 run?
1802 of 2118 indexed open-weight models fit a Apple M1 at 8,192 context with f16 KV cache, the largest being Wan2.1-VACE-14B at Q5_K_S. That covers text, vision-language, image, video and speech models.
How much usable memory does a Apple M1 actually have?
Its nameplate is 16 GB, but about 11.16 GiB is available to a model once driver and compositor overhead is accounted for, and only 12 GB of the pool can be allocated to the GPU at all.
Is a Apple M1 fast for local AI?
Its memory bandwidth is 68 GB/s, and that figure — not teraflops — is what governs token generation speed. Capacity decides what you can run; bandwidth decides how fast it runs.
