    OpenAI launches textGrain to watermark EU AI text

    OpenAI just launched textGrain, an invisible statistical watermarking system for generated text, in response to the EU AI Act. Global API users can opt in now, while ChatGPT and Codex in the EU will turn it on by default in the coming weeks. Why it matters: text detection is notoriously fragile—swapping 25% of words cuts detection to 17%—which is why OpenAI is limiting detector access to researchers for now.

    OpenAI adds deep watermarks across text, audio, and images

    OpenAI just rolled out a multi-layered provenance system across its AI outputs, pairing C2PA metadata with invisible SynthID and textGrain watermarks. It also launched a public verification portal so anyone can check whether an asset came from its models. Why it matters: embedding signals directly into pixels and token choices makes AI origins much harder to scrub off.
