The Mirage of Autonomous AI Scientists
Science as AI’s killer application cannot succeed without scientist-AI interaction: Introducing Hypogenic.ai.
cichicago.substack.com
AI can accelerate scientific discovery, but only if we get the scientist–AI interaction right.
The dream of “autonomous AI scientists” is tempting:
machines that generate hypotheses, run experiments, and write papers. But science isn’t just automation.

Come chat with us at the poster! We will bring some unicorn ducks too!
Will be at #NeurIPS2025 presenting “Concept Incongruence”!
🦄🦆 Curious about a unicorn duck? Stop by, get one, and chat with us!
We made a new demo for detecting hidden conflicts in system prompts to spot “concept incongruence” for safer prompts.

Academic peer review has mostly treated paper as the single source of truth, even when the accompanying code is available. We can change this with research agents, and there is a lot of exciting work going forward! If interested, reach out to Xiaoyan or me!
Research agents are getting smarter. They can write convincing PhD-level reports 🧑🔬
But has anyone checked if the way they find their results makes any sense?
Our framework, MechEvalAgents, verifies the science, not just the story 🤖

We're launching a weekly competition where the community decides which research ideas get implemented. Every week, we'll take the top 3 ideas from IdeaHub, run experiments with AI agents, and share everything: code, successes, and failures.
It's completely free and we'll try out ideas for you!

❓ Does an LLM know thyself? 🪞
Humans pass the mirror test at ~18 months 👶
But what about LLMs? Can they recognize their own writing—or even admit authorship at all?
In our new paper, we put 10 state-of-the-art models to the test. Read on 👇

Yes, more companies should move to Chicago!
Chicago is a city, a far better (and bigger) one than Seattle? It's not a purge if you move your company somewhere you can afford? I'm not suggesting living in a woods. There are lots of communities with great hipster restaurants & entertainment even in the rustbelt, you just have to look a little.

AI can write complex code but fails at 4-digit multiplication. 🤔 New research by @elenal3ai.bsky.social & @chenhaotan.bsky.social reveals why billions of parameters can't solve grade-school math—and what it takes to fix it. It's about how AI learns, not how much it learns.

Every clause in this (on AI science) !!! 👇👇
It’s also a resource allocation problem: deciding what matters, which hypotheses to test, and which results to trust.
Automation can produce knowledge, but meaning comes from human judgment.
