MIT团队提出自我演进AI科学家框架，核心创新是让AI识别当前推理空间过小并主动添加新科学概念，而非仅在固定模式内搜索。论文将数据点、模型、工具输出、失败、声明均视为带类型的artifact，明确区分检索（添加已知对象）、搜索（探索固定schema）和发现（可验证的模式扩展）。通过类型化copresheaf与Kan障碍理论证明，真正发现是可验证的schema扩展：旧证据由左Kan扩展传输，创新性通过逐点残差量化。案例包括Builder/Breaker模型发现蛋白质模式条件顺应性，以及CategoryScienceClaw发现各向异性纤维网络刚度规则。论文arXiv:2606.01444（2026）。
New MIT paper, great idea for self-evolving AI scientists from
Tries to make an AI scientist notice when its current way of thinking is too small, then add new scientific concepts instead of merely searching harder.
The problem is that most AI science systems still search inside a fixed setup, even when real science sometimes needs new kinds of variables, tools, tests, or claims.
The paper’s core idea is to make every data point, model, tool output, failure, and claim a typed artifact, where typed means the system records what kind of thing it is and how it was produced.
Then the system can tell the difference between retrieval, which adds known things, search, which explores a fixed setup, and discovery, which changes the setup itself.
So novelty AI scientists is not defined by surprise, fluency, or benchmark gain, but by what could not be expressed inside the previous schema.
A serious attempt to formalize something most AI systems still fake: the difference between finding an answer inside a language and earning the right to change the language.

Title: "Self-Revising Discovery Systems for Science: A Categorical Framework for Agentic AI"
We've made a breakthrough in self-evolving AI scientists moving from "search" to "principled discovery": Scientific discovery requires that the search space itself changes, and an AI scientist must perceive this shift without intervention. We built an AI that achieves this for the first time with the ability to discover the scientific vocabulary it reasons in. Evidence, tools, artifacts, verifiers, failures & claims become typed provenance. We show three distinct modalities: 1) retrieval, adding known objects; 2) search, exploring a fixed schema; and critically: 3) discovery, a verified regime transition. We solve the open-endedness evaluation problem by lifting agentic workflows into a typed copresheaf and proving, via a Kan obstruction, that true discovery is not unbounded generation but a verifiable schema expansion: old evidence is transported by Left Kan extension, and genuine novelty is mathematically quantified by the pointwise residual beyond the transported image - separating discovery from mere search and making novelty objective and measurable rather than a subjective judgment or benchmark delta. Our AI scientist is built in a way that does not pre-conceive the approach it chooses; instead, we endow the system with formal power to adapt, evolve, and reason from first principles. Case studies include: 1⃣Builder/Breaker model that discovers mode-conditioned compliance in proteins; 2⃣CategoryScienceClaw that finds anisotropic fiber-network stiffness rules.
