Can the Apple M3 run Hy-MT2-30B-A3B?
IT FITS
Yes. 6 of 9 formats evaluated fit in 24 GB, the largest Apple M3 configuration, at 8,192 tokens. 2 of them are sized from a published file; the rest are rebuilt from the pinned architecture. The best quality that fits is Q5_K_M, needing 22.8 GB and running at an estimated 27 tokens per second.
Fitting in memory is not the same as loading. Whether the runtime and version you have supports this architecture and format on this machine has not been tested here.

How long a conversation. At Q5_K_M, this pair holds 20,175 tokens of context — roughly 15,131 words — needing 24.0 GB. Past that the Apple M3 runs out of memory, not the model out of context, which would allow 262,144. This is the wall a long chat hits after it has already loaded fine. The nearest round setting below it is 16,384.
By memory configuration
The Apple M3 is sold with 8, 16 or 24 GB of unified memory, and the amount decides the fit. Each row is the best format that fits in that much at 8,192 tokens, whole model resident.
Every format evaluated
2 of them are sized from a published file; the rest are rebuilt from the pinned architecture. The Basis column says which is which for each row. Decode and first-token figures are calibrated estimates, not runs on this card.

Sized at 8,192 tokens of context with the whole model resident — weights, the KV cache and the runtime reserve, offload off. Speed is only quoted for a format that fits: a rate for a configuration that cannot load is not a fact about anything.
Why the first-token figure is the same on every row
First token is modelled from the arithmetic the prompt requires, and that count does not change with the weight format — which is why it reads the same on every row. Real prefill does vary by format, because a quantized matmul is a different kernel; this model does not capture that, and the figure should be read as an order of magnitude rather than a ranking between formats.
What the labels mean
- published data
- Read from a published source — a file's byte count, a model's configuration or a manufacturer's specification — or exact arithmetic on such values. Not a measurement on a machine.
- reconstructed size
- Weight size reconstructed from the pinned architecture, because no published file exists.
- size range
- Only a lower and an upper bound are claimed for this weight size.
- estimate
- Calculated from sourced inputs by a stated method; an estimate, not a measurement.
This page fixes the context at 8,192 tokens and one device. Batch, concurrent users, KV-cache format, clusters and rental cost are all in the calculator, already set to this pairing.

Hy-MT2-30B-A3B’s architecture is read from its publisher’s own config.json at a pinned revision, and the Apple M3’s 24 GB and 100 GB/s come from the manufacturer’s specification. How far each figure can be trusted is published, per format and worst case included, on the accuracy scorecard.
