LOCI is a Line-of-Code Intelligence platform that revolutionizes system observability. At its core is the proprietary Large Code Language Model (LCLM), a vertical LLM specializing in comprehensive system workload analysis focusing on power, performance, and reliability. This advanced model middleware, trained on SoC real-time tracing data since 2017, leverages extensive experience in mission-critical safety projects and HPC in the automotive sector. Our tuned middleware LCLM boasts a vocabulary 1000 times smaller than LLM, with reinvented tokenizers and pipeline training using only 6 GPUs, making it exceptionally efficient. LOCI uncovers anomalies in static data, shifts observability left, and predicts emerging trends in dynamic data discovering hardware and software reliability issues.
