AI News Flash: Hitachi Energy announces plan to acquire Canadian transformer materials and parts supplier Canduct, with the core goal of strengthening its North American local production capacity. The direct backdrop to this acquisition is the surge in data center construction across North America driving significant increases in grid infrastructure demand, particularly high-voltage transformer materials have become a bottleneck in the industry — companies without local supply chain support will struggle to respond quickly to market demand.

AI News Flash: Researchers collaborate with OpenAI to use its reasoning model to help diagnose rare diseases, successfully identifying 18 new diagnoses in previously unsolvable cases. The core of this achievement lies in the reasoning model’s deep step-by-step reasoning ability, which can systematically integrate patient symptoms, genetic data, and medical literature to propose hypotheses that traditional diagnostic processes struggle to reach. For rare disease patients, getting a definitive diagnosis often requires years or even decades of waiting, because these diseases have few cases and clinicians accumulate very limited diagnostic experience

AI News Flash: During the G7 summit this Wednesday, French President Macron and Indian Prime Minister Modi publicly expressed concerns about the US potentially unilaterally cutting off other nations’ access to US-made top-tier AI models.

The day after submitting to the hackathon I finally had a moment to look back at the whole system. Turned out something surprising — across those 7 days we spent more time thinking about architecture than writing code. Days 9-12 were 4 solid days of talking to my mom, my aunt about real collections scenarios, listing D-001 through D-022 design decisions, drawing drawio v1/v2/v3. Days 13-15 were the only code days. This post is the full design journey — why I picked ‘outstanding balance’ over ‘gross invoice,’ why 9 agents in 3 layers, the 4 hidden cases nobody talks about — all from imagining real conversations with real people on bad days.
