- Financial Document AI with source evidenceThe system extracts financial facts from Arabic and English audited statements. Each value keeps its source reference.34% to 94%Measured result: Internal extraction and calculation evaluation; exact denominator and review scoring not recordedDocument AI / financial extraction
- Onchain wealth automationThe system connects onboarding, money movement, policy checks, scheduled workers, and Aave V3 position protection.84 positions / 0 liquidationsMeasured result: Managed Aave V3 positions over 18 months; observed production historyStackit.ai / financial systems
- GLM-5.2 sparse attention on BlackwellA 504-billion-parameter checkpoint loaded on eight RTX PRO 6000 GPUs. Output then repeated because the sparse indexer ran on the wrong layers.240K-token contextMeasured result: Cold single-prompt validation on the sparse path; 43 to 45 tokens/s applies only to short-to-medium contextvLLM / inference investigation
