Korean-language service teams must test Jev. Confidence summarizes probabilities, not the accuracy rate. That number alone cannot show how often automated decisions are wrong on your service's data. Choice selects a category, Score evaluates on a scale, and Noul asks for the probability that something is true. The TypeScript SDK infers answer types from the question definition, helping you plan how code handles each result. If you build a Korean-language service, use your own data to measure both the automated processing rate and the rate of incorrect decisions. Read the article for the question types and the checks to make. #Jev #AIDevelopment #TypeScript #DecisionModels

1803: history readers trace Balmis at sea. The Balmis Expedition left A Coruña, Spain, on November 30. Vaccinating children in succession kept the smallpox vaccine viable during the long voyage. Official correspondence from 1804 records uncertainty about departure and disagreements over food and lodging. Those records matter when weighing the children's treatment separately from the vaccine's transport. Training local medical workers and establishing vaccination boards were measures to keep vaccinations going after the expedition. For readers studying this voyage, the article separates those efforts from the later eradication of smallpox in 1980. Read the article for the evidence behind each distinction. #BalmisExpedition #Smallpox #MedicalHistory #VaccineHistory

API teams plan a Claude Opus 5.5 migration. The model name is only part of the check: inference and tool-calling settings matter too. Standard input costs $4 per million tokens and output costs $20 per million tokens, both 20% below Opus 5. Cache reads cost $0.20 per million tokens, a 60% reduction. Those rates help you estimate a workload, but Anthropic's 40% task-cost reduction comes from its evaluation. Your costs depend on token and cache use. Anthropic reports a Terminal-Bench 4.0 score of 66.4%, up from 52.3%. The article places that result alongside pricing to help weigh reported performance against cost. For developers migrating an existing API, read the comparison before checking your settings. #Claude #Anthropic #AIDevelopment #CodingAgents

Will public rentals cover middle-class renters? The plan aims to extend universal public rental housing to the middle class. Income and asset caps and rents are not yet confirmed. Figures of 180% to 200% of standard median income and rents at 70% to 80% of market rates were not confirmed move-in rules when the plan was announced. From 2026 to 2030, the public housing target is 1,188,000 units, including 917,000 in the Seoul metropolitan area. It counts starts, purchase agreements and contracts, not move-ins. Checking project notices instead of treating that target as available homes can save time in your housing search. For middle-class renters considering future projects, later policy announcements and each project's notice are where to confirm eligibility, rents and application dates. #PublicHousing #RentalHousing #HousingPolicy #SeoulMetro

September 2026: yen investors face a rate gap. After that month's policy decisions, the U.S.-Japan gap was 2.50 to 2.75 percentage points. A Japanese rate hike alone does not close it. The article explains why overseas income reinvested abroad may not turn a current account surplus into immediate yen buying. If you buy yen with won, both dollar-yen and won-dollar rates affect the cost. Checking both gives a clearer idea of how much won is needed. Businesses can compare the currencies of their revenue and costs to assess their exposure. For yen investors, people buying yen with won, and businesses with revenue or costs in different currencies. Read the article for the full explanation. #JapaneseYen #ExchangeRates #MonetaryPolicy #ForeignExchange
