# Micius Harness

Micius-Flash is a 27-billion-parameter engineering model with native multimodal input and a 256K-token context window, specialized and evaluated primarily on semiconductor engineering, and released as an open-source model. A knowledge-tree-driven data flywheel organizes semiconductor knowledge, synthesizes data and validates quality, and multi-teacher on-policy distillation merges four expert capabilities, knowledge and reasoning, hardware coding, multimodal understanding and agentic tool use, into one student model. It averages 64.2% on 12 hardware coding benchmarks, 15.0 points above a same-size general-purpose baseline, and scores 62.4% on a semiconductor-specific agent benchmark, 17.2 points above that baseline.
