7B is the realistic daily range
Capacity estimate: up to roughly 7B comfortably, 13B tightly. Context, quantization, and running apps change real-world fit.

13B is a capacity edge, not a benchmark or a guarantee. Even the “comfortable” 7B tier is an editorial estimate, not a tested throughput result. Actual fit depends on weight quantization, model architecture, KV-cache and context size, available RAM, backend and concurrent apps.
16GB 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

Before spending money
Four checks that matter more than a model-size badge
- Match the exact RAM, SSD, chip and port configuration to the linked offer. A similar product name does not establish identical hardware.
- Estimate memory for your actual quantized model, chosen context and runtime; include macOS and app headroom. Do not treat “70B supported” as a throughput guarantee.
- Check the complete checkout total, delivery location, seller and return conditions. Listings here are not real-time price quotes.
- For used devices, inspect battery health, hardware locks, repairs and warranty before paying.
