MIT CSAIL's 'Machine Studying': agents that pre-study corpora instead of searching on-the-fly

Weaviate Podcast episode 148 features MIT CSAIL PhD student Jacob X. Li discussing his 'Machine Studying' paper: instead of agentic search systems learning on-the-fly, agents could study a corpus (codebases, drug discovery papers, system logs) ahead of time — without knowing the downstream task — like a student preparing for an unseen exam.
Key ideas:
- Frames what always-on 24/7 agents should do when nobody is asking them anything: build arbitrarily deep understanding in advance rather than leaning entirely on inference-time compute.
- The paper's definition of expertise is notable: an expert efficiently uses inference-time compute — upfront study buys efficiency at inference.
A direct counterpoint to the inference-time-compute paradigm: can understanding be pre-accumulated instead of looked up each time?
