OpenAI Expands ChatGPT Plugins with App-like Interfaces and Automations

Amazon Ads Rebrands DSP to DVA, Launches Agentic Assistant
At its unBoxed event, Amazon Ads announced a major overhaul of its advertising platform. The Amazon DSP has been renamed DVA (display, video, audio), and the DSP and sponsored ads console are merged into a new interface called 'The Amazon Ads Agent.' This agentic system, powered by AI, unifies workflows for advertisers, enabling a seamless experience across campaign types. New features include DVA+ with Performance Plus and Brand Plus campaign types, and Full-Funnel Campaigns for small advertisers to easily run ads across channels like streaming TV and audio. The platform auto-generates media plans and optimizes campaigns, with natural language analytics. This push aims to simplify the historically complex and siloed Amazon ad platform.
Amazon Ads unifies buying tools, boosts AI in campaigns
At its unBoxed conference, Amazon Ads announced major changes to its advertising platform, including renaming its unified platform to Amazon Ads Agent and launching Full-Funnel Campaigns and DVA+. These products aim to collapse previously separate advertising workflows, such as sponsored ads and programmatic buying, while giving Amazon's AI a larger role in media planning and optimization. Advertisers can specify objectives, budget, and creative, while Amazon's AI handles execution. The moves are intended to make programmatic advertising accessible to a wider range of advertisers, from small businesses to enterprise buyers. However, the announcement comes amid ongoing FTC allegations about secret surcharges in Amazon's ad auctions, raising questions about transparency and control as Amazon's AI assumes more decision-making responsibilities. Industry observers advise caution and emphasize the need for advertisers to interrogate auditability, third-party data integration, and fee structures.
