人工知能の最新動向 — モデル、資金、半導体、規制、導入事例。
The EU AI Act entered into force on 1 August 2024 and applies in stages. The bans on prohibited practices and the AI-literacy duty applied from February 2025; obligations for general-purpose AI models from August 2025; and the main high-risk regime from August 2026, with product-embedded high-risk systems following in 2027.
デモは短い正常系を人が見ている前で一度だけ回す。本番は監視なしで何千もの変種を回し、そこでは各ステップの誤り率が掛け算され、広すぎる権限が一つの誤判断を事故に変える。うまくいく導入は範囲を狭め、各ステップを安く検証し、不可逆な行為ごとに門を置く。
Price per token has fallen sharply through better hardware, smaller distilled models and serving optimisations. Consumption has grown faster: longer contexts, reasoning models that generate far more tokens per answer, and agents that turn one user action into dozens of model calls. Falling unit prices with rising unit counts produce larger bills.
Answer engines synthesise a response from several sources and show it above or instead of the traditional link list, so a query that once produced a visit can now be resolved without one. Publishers see impressions and citations rise while click-through falls, which breaks the advertising model that assumed every answer required a page view.
On common benchmarks the best open-weight models now sit close to frontier commercial models, and for many routine tasks the difference is not noticeable. The remaining gaps show up in long-horizon reliability, tool use, very long contexts and safety tuning — and in the operational work of running them yourself.
