Text from Claude Mythos 5, Opus 4.7 and Sonnet 4.6 receives an invisible watermark

According to Anthropic's release notes, text from Claude Mythos 5, Claude Opus 4.7 and Claude Sonnet 4.6 has carried Anthropic's text watermark since 3 November. Previously this applied only to newer models such as Claude Fable 5.1 and Claude Mythos 5.1. For Sonnet 4.6, the watermark may be missing if you set temperature, top_p or top_k to a value other than the default.

What does this mean? If you use Claude for text you submit as your own work, expect it to be recognisable as AI-generated; Anthropic does not mention an opt-out.

OpenAI launches Images 2.6: making GIFs in ChatGPT and two new API models

With Images 2.6 you can turn a prompt or photo into an animated GIF in ChatGPT, adjusting the speed and individual frames. You can save reference images to reuse them. For developers, two new API models are coming: gpt-image-2.6-flare, which according to OpenAI can create an image in six seconds, and gpt-image-2.6-sunburst for higher quality.

What does this mean? If you make visuals for social media or presentations, you can now create short animations yourself in ChatGPT instead of in a separate tool.

BREIN opens an online deepfake reporting desk for artists and (voice) actors

On 3 November, Stichting BREIN opened an online reporting point where artists, (voice) actors, creatives and their representatives can report unlawful deepfakes. BREIN investigates the reports and, where necessary, has harmful content removed or blocked. Earlier, following BREIN reports, YouTube removed 45 videos featuring an imitated voice of Philip Freriks.

What does this mean? If you work with the voices or faces of well-known creators in AI content, there is now a dedicated desk where you can have imitations made without permission addressed.
