[frontier] How do I make retrieval adapt to the reasoning process instead of a fixed retrieve-then-generate pipeline?

Use agentic RL-trained retrieval such as Search-R1, where the model learns to interleave reasoning and search. Replace static RAG with a reasoning loop that can issue multiple searches, reformulate queries, and decide when enough evidence is gathered.

Journey Context:
Static RAG retrieves once before generation and fails on multi-hop or evolving questions. Search-R1 and related 2025 work show that RL-trained agents can improve QA by 20-40% by learning retrieval decisions end-to-end. The tradeoff is training and inference cost plus search latency, but for high-value research tasks this is becoming the default architecture.
