The theme of the week is agents: software that does tasks for you, not just answers questions. That is why ordering apps, office tools and safety groups all showed up in the same seven days. If you want a refresher on how agents work, read our explainer on AI agents.
Company claims about new models, such as benchmark wins or price cuts, come from the companies themselves. Independent tests usually follow within weeks, so treat launch-day numbers as a starting point.
