The part worth studying is the 25 MB of Rust wrapped around it.</p> <p>EdgeHome Harness pairs MiniCPM5-1B, 688 MB on disk and about 1 GB at runtime, with a Rust harness between 25 and 64 MB, targeting devices with 2 GB of RAM. A community developer built it; OpenBMB put it on stage. The line everyone will quote is that a full agent stack fits on ultra-constrained edge hardware. The design decision that matters is different: the model is not allowed to do anything.</p>
