SAMI Chimera: Sub-Neuronal Weight Surgery, Chimeric Base-to-Chat Synthesis, and Tensor Isometry Certification in DeepSeek-MoE-16B

Post-training preference alignment (RLHF, DPO, KTO) enforces refusal behaviors by establishing persistent attractors in intermediate transformer representations. Current refusal removal techniques, notably directional ablation, operate macroscopically by subtracting a 1-dimension...

SAMI Omni: Asymmetric Mixture-of-Experts Topology and Memory-Decoupled Multimodal Inference on Commodity Hardware

Monolithic scaling of multimodal foundation models has introduced an operational barrier: modern 30B+ parameter architectures typically require distributed enterprise accelerators, restricting local deployment on consumer workstations. While split-device tensor offloading builds...
