OpenAI is adding an invisible, machine-readable watermark called textGrain to ChatGPT and Codex text in the EU to comply with the AI Act, while making it optional for API users worldwide.
OpenAI is rolling out an invisible, machine-readable watermark called textGrain in the text output of ChatGPT and Codex, starting with users in the European Union. OpenAI says the watermark matched or exceeded other approaches such as Google DeepMind's SynthID for text.
Why it matters: It brings a provenance signal to OpenAI's text output, beginning in the EU, where AI transparency rules apply.
