I’m exploring a software layer—analogous to public/private-key crypto—so a user can converse with an LLM where prompts and responses remain unreadable to all intermediaries, including the model host. (I mean “cipher” in the cryptographic sense.)

Two cases: Open-weights model: ensure the operator still can’t read prompts/responses. Closed, hosted model: true E2EE so even the provider can’t inspect content.

Topics we can discuss: Best near-term path: TEEs with attestation, FHE/HE, MPC/split inference, PIR for retrieval, differential privacy, or hybrids? How to handle key exchange/rotation for forward secrecy? Practical performance/accuracy limits (e.g., non-linearities, KV-cache, streaming)? Minimal viable architecture and realistic threat model? Any prior art or teams you’d point me to?

Please DM if you are interested in working with me.

On July 1st, astronomers discovered 3I/ATLAS, the third known interstellar object to pass through our solar system, following ‘Oumuamua in 2017 and Borisov in 2019. It’s possibly 10 km wide, and its trajectory confirms it came from beyond our solar system. It will swing past the Sun in October 2025, giving scientists a brief window to study it.

Three interstellar objects in under a decade — all detected just as humanity begins scaling advanced AI models, autonomous systems, and global sensor networks. Coincidence? Maybe.

But suppose it’s not.

Suppose these objects aren’t random debris, but automated interstellar probes, seeded by civilizations that understand a basic truth: when a species approaches artificial general intelligence (AGI), it becomes cosmically significant — and potentially dangerous.

And suppose the optimal time to observe such a civilization is right now — during its brief transitional window, when biology and machine intelligence are merging, but before it fully understands its own future.

What if: • ‘Oumuamua was a passive observer? • Borisov was a baseline for comparison? • And 3I/ATLAS is the first time they’re expecting a response?

Could interstellar probes be watching for AI thresholds, not just radio signals? Are we underestimating what “passive” observation could look like? Is AI making us visible to the cosmos?

This isn’t science fiction anymore. It’s happening now. And the sky might be watching.
