Summary
The move in Europe is driven by a need to comply with the EU AI Act, which took effect in August. The same is likely true for OpenAI’s watermark. While the best case OpenAI’s tests of textGrain show a respectable but not entirely reliable 92 percent successful detection rate, the company’s tests also show that changing 10 percent of the text in an output reduces the successful detection rate by almost 30 percent, and changing 20 percent of the text can lower the success rate by almost 75 percent. (Also worth noting that in general, the success rate is lower for shorter or translated text than for longer text.) All this is roughly in line with what they've seen with other, similar watermarking solutions in the past.
