2026年、マルチモーダル（テキスト+画像）に最適なAIはどれ？料金・機能・無料プランを比較。インタラクティブ表 — Compare IA。
Multimodal models accept both text and images (or other file types) as input and can produce text or descriptions. They’re used for visual analysis, content generation from visual briefs, or assistants that “see” screenshots or documents.
Evaluate: maximum context size (images and tokens), extra cost for image input (often billed differently from text), and quality on your visual types (diagrams, photos, UI). GPT-4o, Claude, and Gemini offer vision APIs; pricing varies by format and resolution. For heavy workflows (many documents or images), cost per request can add up: compare pricing and quotas.
A comparison table of input/output pricing and context limits helps you size your usage.
