Can MacBook Pro M1 Max 32GB run AI21-Jamba-Large-1.5?

METAL

No — AI21-Jamba-Large-1.5 at Q4 needs ≈ 260.09 GB even at 4K context, beyond the MacBook Pro M1 Max 32GB's 32 GB LPDDR5. It would only run with heavy CPU/disk offload. FP16 needs ≈ 877.92 GB — does not fit on this card. Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s. Methodology.

Fit & speed by quant and context

Quant	Context	VRAM needed	Fits?	tok/s (decode)
Q4	4K	260.09 GB	No	—
Q4	8K default	299.95 GB	No	—
Q4	32K	539.11 GB	No	—
FP16	4K	838.06 GB	No	—
FP16	8K default	877.92 GB	No	—
FP16	32K	1117.08 GB	No	—

Fits = weights + KV(ctx) + 1 GB overhead ≤ 95% of VRAM. Measured anchors are context-agnostic; the fit verdict is recomputed per context. A missing tok/s means the model is far beyond this card (offload-only territory).
