Google Cloud unveils Gemini エージェント for business tasks

Google Cloud used its "Gemini at Work 2026" event to push beyond prompt-and-response AI toward an agent that holds business context and keeps working on a task for days. The company describes it as able to take on a specific organizational role, such as a project manager working as a team member, and to be given an email address or account so colleagues can reach it with an "@mention" in Google Chat like any coworker. It also automatically selects the model it judges best for each task, which Google says improves accuracy on hard jobs while cutting cost on simple ones. The concrete customer results reported at the event — Hitachi's up-to-400% productivity gain, NTT Docomo's 450,000 hours of work time created per year, and Sompo Holdings' cut in custom agent build time from one week to one day — suggest early adopters have already put such agents to work, though no general availability date or price was announced.
