Researchers present PPDL, a framework for predicting channel-level user retention ratios in multi-channel paid user acquisition. The method integrates physical priors with deep learning to capture the sharp early churn typical of retention curves. Accurate early forecasts are intended to help marketers allocate advertising budgets more effectively.
A new arXiv preprint introduces AgenticGen, a framework that treats advertising video creation as an agentic reasoning task shaped by reward signals rather than simple clip synthesis. The method conditions generation on a specific product and aims to optimize for online business outcomes, building on video foundation models that can produce realistic footage from multimodal inputs. The paper appears as a cross-listing in arXiv's AI and computational linguistics categories.
Creators are discovering sponsored posts and advertisements that use AI-generated likenesses of them without permission. The fraudulent ads confuse followers and erode trust in the influencers' own endorsements. The report highlights how difficult it is for individuals to detect and remove such impersonations.
San Francisco's City Attorney's Office has sent Meta a request for information about how advertisements promoting AI-generated child sexual abuse material appeared on Facebook and Instagram. Meta responded that the matter falls outside the city's authority. The inquiry follows reporting that such ads ran repeatedly on the platforms.
OpenAI announced that advertising within ChatGPT has reached a $1 billion annualized revenue pace. The company says it is now rolling the ads offering out to more countries, framing the move as a way to keep free and lower-cost ChatGPT tiers available. The revenue figure covers only the advertising business, not OpenAI's overall income.
WHY IT MATTERS ↘An ad-funded free tier resets the price floor for consumer AI, pressuring rivals to match on cost while turning ChatGPT's answers into an ad surface where placement incentives can conflict with neutrality. It also gives OpenAI a revenue stream independent of API and subscription demand, strengthening its position in the compute-heavy race.
