FreeToken, from a team at UC Berkeley and MIT, proposes a serving stack that treats a personal machine's CPU, GPU, and RAM as a single elastic compute surface, adapting to what's actually available rather than committing to a fixed offloading strategy. The result: a 35B model on an 8GB laptop GPU, 284B on a gaming desktop, and the 753B GLM-5.2 on a single workstation with one high-end GPU.

By overriding Wasmtime's memory allocator to back Wasm linear memory with a Metal buffer via makeBuffer(bytesNoCopy:), the author collapses the Wasm–GPU boundary entirely: 0.03 MB overhead vs 16.78 MB for the copy approach, ~9 ms/token for Llama 3.2 1B on M1, and KV cache snapshots that restore 5.45× faster than recomputing prefill.
