OpenAI Marks AI-Generated Content

OpenAI:

Starting today, API customers globally will be able to opt in to text watermarking for select models. Text watermarking will remain off by default in the API. Over the coming weeks, we will add an invisible watermark to eligible ChatGPT and Codex text output in the European Union. More details about how textGrain works can be found in our technical report (opens in a new window), which will be updated with additional details in the coming weeks. We also plan to make the technology available in open source so that others can build on it. At a target false positive rate of 1%, our detector identified watermarks in about 80% of 200-token passages, compared with about 95% of 400-token passages, for content such as psychology.

Via John Gruber (Mastodon):

OpenAI has made this available via an API so developers should be able to actually see if this adulterates text output with real-world usage. Third, none of these companies have yet made their watermark detectors publicly accessible. I remain highly skeptical that they will work as advertised in the real world. I think this is all somewhat of a sham to claim compliance with the EU AI Act without actually providing anything that anyone can actually use in a practical way.
