# News: OpenAI puts visual ads inside ChatGPT image generation and opens ad measurement to third parties

> OpenAI introduced a visual ad format for ChatGPT on 2026-10-05, to be tested first during image generation for users on the Free and Go plans. Ads are clearly labelled and kept separate from the image being created, and OpenAI states advertising does not influence ChatGPT answers. Alongside the format it expanded ChatGPT Ads measurement: attribution partners now include AppsFlyer, Triple Whale, Adjust, DV Rockerbox, Northbeam, Branch, Singular, Kochava, Airbridge and Tenjin, full-funnel measurement runs with Fospha, Measured and INCRMNTAL, geo-based incrementality experiments are in exploration with Haus, Measured and WorkMagic, and brand-suitability evaluation is in development with DoubleVerify and Integral Ad Science. Search Engine Land reports the format enters testing later in October with a group of US advertisers, on a platform OpenAI says reaches 1.2 billion people weekly.

## What it means for buyers

The largest consumer AI assistant is now monetising its free tier with ads, which sharpens the free-versus-paid calculus in our personal-agent comparison: Meta's Muse is ad-funded by design, OpenAI's free tier is converging on the same model, and paid tiers (ChatGPT Go upward, invite-only Instinct) are what buy an ad-free experience. For advertisers, third-party attribution and incrementality support makes ChatGPT Ads comparable against search and social placements for the first time; the early results are partner-reported and single-source, including a WeightWatchers attributed CPA 15.3 percent below its blended paid-search benchmark measured by DV Rockerbox, and should be treated as unverified until independent measurements accumulate.
