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 M2 run?
- 1820 of 2118 indexed open-weight models fit a Apple M2 at 4,096 context with q4_0 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 M2 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 M2 fast for local AI?
- Its memory bandwidth is 102 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.
