"WaltTeam team on AMD AI League Hackathon"

WaltTrace answers short factual questions from mixed engineering documents while returning the exact files needed to support each answer. It parses PDF, Word, Excel, CSV, logs and source files, and uses a local vision-language model to read diagrams, scanned pages and equipment labels. Retrieval follows identifiers between incident reports and lookup tables, allowing answers that require more than one document. Generated quotations are checked against indexed source text; unsupported answers are refused with an empty answer and citation list. Qwen2.5-VL-7B runs on a real AMD GPU through ROCm PyTorch. All weights are embedded in the mandated container base, and the application runs without outbound network access. Indexing starts a resident model behind a private Unix socket so each fresh question process avoids reloading the weights. Malformed, unreadable, encrypted and unsupported files are skipped independently. The development report documents actual GPU timings, memory readings, individual answers and citation checks. Public-sample results are development evidence, not a claim about hidden evaluation scores or League points already awarded.
