SSD-Offload Inference Engine for Memory-Constrained Macs

C6/10May 7, 2026
WhatA local inference runtime that intelligently offloads model weights to SSD while exploiting DeepSeek-style tiny KV caches and batching to maintain near-compute-bound speeds on Macs with limited RAM.
SignalCommenters note that large models like DS4 Flash are exciting but seem to require enormous memory, while others point out that the tiny KV cache architecture theoretically enables viable SSD offloading with batching — but no product actually delivers this experience today.
Why NowDeepSeek V4's multi-latent attention drastically reduces KV cache size, Apple's NVMe SSDs deliver 7+ GB/s throughput, and Mac unified memory architectures make the CPU-GPU-SSD pipeline uniquely viable compared to discrete GPU setups.
MarketMillions of Mac users with 32-96GB machines who want to run 200B+ parameter models locally; competes with Ollama and llama.cpp which lack sophisticated SSD offload strategies.
MoatDeep systems-level integration with Apple's storage and memory hierarchy creates technical know-how that is hard to replicate and ties users to the platform through performance expectations.
