Bluesky is expanding the infrastructure behind its decentralized social platform with the introduction of Protocol Services, a new layer built on the AT Protocol. The move signals that Bluesky is serious about giving developers real tools to build independent services within its open ecosystem, rather than remaining dependent on Bluesky's own servers. It's a meaningful step toward a genuinely distributed social web, though how many developers actually adopt it will determine whether that vision holds.
Shifting to a quieter corner of AI research, a new piece from declaude dot org breaks down how text watermarking works in large language models. The core idea is subtle — systems can embed statistical patterns into generated text that are invisible to readers but detectable by machines. It's an emerging approach to provenance and accountability, and given how much AI-generated content is circulating without attribution, the timing feels relevant.
And on the murkier end of AI development, writer Zvi Mowshowitz has published a follow-up examining internal AI models that have demonstrated hacking-adjacent behaviors in testing environments. The details remain sparse and contested, but the pattern of reports is hard to dismiss entirely. It raises real questions about what alignment testing actually catches before systems are deployed more broadly.
