# Gemini Deep Research
Paid, web-grounded research via Google's Gemini Deep Research and Deep Research Max APIs. Use this skill when citation quality, recency (post-2025), and comprehensive cross-referencing matter more than cost. For $0 alternatives, see the alternatives table below.
See [`decision-table.md`](decision-table.md) for the full routing reference with worked examples and cost-cap escape paths.

## 1. When to Use This Skill vs. the Alternatives
| Question shape | Tool | Cost | Wall time |
|---|---|---|---|
| "What's hot on Reddit / X / TikTok about X this week?" | `last30days` | $0 (or SC API) | 2–8 min |
| "What are the practical differences between A and B?" with general web coverage | `deep-research-queue` (LDR) | $0 | 5–12 min overnight |
| "Recent (post-2025), authoritative, ≥10 sources, citation quality matters" | **`gemini-deep-research` DR tier** | $1–3 | 5–20 min |
| "Cross-service matrix / due-diligence / comprehensive landscape" | **`gemini-deep-research` DR Max tier** | $3–7 | 20–60 min |
**Quick routing heuristic:**
- Social-media conversation, trends, Reddit/X → `last30days`
- General synthesis at $0, can wait overnight → `deep-research-queue`
- Authoritative citations, recent web coverage, need it now → DR tier
- Multi-service matrix, due-diligence depth, 60-min window OK → DR Max tier
