Oct 1, 2025Month 2025-10: Focused on CPU plugin caching enhancements and CI stability. Delivered weightless cache support and serialization improvements for the CPU plugin, including optimization for OPTIMIZE_SIZE and a refactor of serialization/deserialization to support weightless caching attributes while preserving compatibility with existing models. Improved CI reliability by relocating sporadic tests from precommit to nightly, enabling continued investigation without blocking sanity checks. These changes yield faster model loading, smaller cache footprints, and a more stable CI, accelerating iteration and deployment readiness.
