Deep Research API Landscape (2026)
Extracted: 2026-02-13 Context: AIによる自動リサーチシステムを構築する際の技術選定
Problem
Deep Research品質のリサーチを自動化したい場合、 Playwright + ヘッドレスブラウザでWeb UIを操作する方法が 思い浮かびやすいが、ToSリスクと脆弱性がある。
Solution
2026年時点で、主要3社が公式Deep Research APIを提供している。 ブラウザ自動化は不要。
| サービス | API | モデル | 特徴 |
|---|---|---|---|
| OpenAI | /responses endpoint |
o3-deep-research-2025-06-26 |
MCP連携、信頼サイト制限 |
| Gemini | Interactions API | Gemini 3 Pro | 最大60分調査、public beta |
| Perplexity | sonar-deep-research |
Opus 4.5 | SimpleQA 93.9%精度 |
追加候補:
- Tavily Research API（private beta、SOTA性能）
- Exa Research API（セマンティック検索特化、SimpleQA 94.9%）
