Deep Survey

Purpose: Precise search, full-depth reading — precise investigation of a specific sub-problem. Not broad, not exhaustive — targeted and thorough.

When to use: User knows exactly what they're looking for and needs precise, detailed understanding. E.g., "How exactly does DPO handle the reward model?" or "What are all the variants of LoRA rank adaptation?"
