From the filePredictedwhat 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.

Aggregated from community-submitted runs, so the spread is wide by nature — it covers different models, resolutions, step counts and settings, not one controlled configuration.

Questions people ask

What AI models can a Apple M3 Pro run?
1828 of 2118 indexed open-weight models fit a Apple M3 Pro at 16,384 context with q8_0 KV cache, the largest being Wan2.2-S2V-14B at Q4_K_M. That covers text, vision-language, image, video and speech models.
How much usable memory does a Apple M3 Pro actually have?
Its nameplate is 18 GB, but about 12.56 GiB is available to a model once driver and compositor overhead is accounted for, and only 14 GB of the pool can be allocated to the GPU at all.
Is a Apple M3 Pro fast for local AI?
Its memory bandwidth is 154 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.
