- What happened
- RECAST framework learns to route language models through retrieval and computation operations to derive evidence from multiple sources rather than retrieve it directly.
- Why it matters
- Matters for engineers building systems that answer questions requiring synthesis across long, heterogeneous documents or data sources.
- Watch out
- Paper is recent preprint; real-world performance on production systems and computational overhead of the routing process remain unvalidated.

The patterns behind this
Each one covers how the technique works, when it earns its cost, and where it breaks.
