Local AI fit
Comfortable up to 24B in 4-bit. 27B–32B gets tight as context grows.
32B is a capacity edge, not a blanket promise: it generally requires strong weight quantization, a short context, and little parallel load. KV-cache precision and the model architecture can materially change the result.
32GB explained Why unified memory is more than model weights Understand quantization, KV cache, macOS headroom, and the difference between “fits” and “runs well.” Open RAM guidePurchase status
Most compelling when priced clearly below a current model with similar memory.
