AI画像生成の機能

AI画像ジェネレーターFAQ

画像モデル、無料クレジット、プロンプト、最初の画像生成に必要なものについての回答です。

1. 1

   AI画像ジェネレーターとは何ですか？

   書いた説明を画像に変えるツールです。見たいイメージを入力し、モデルとアスペクト比を選ぶと、数秒で画像が生成されます。描く必要も、ストック素材を探す必要も、エディターも不要です。

2. 2

   無料で利用できますか？

   はい。登録なしですぐに6クレジットを無料で利用できます。登録すると、さらに12ウェルカムクレジットと毎日3クレジットを無料で受け取れます。有料プランでは、より高精細なモデルと多くの月間クレジットを利用できます。試用に支払い情報は必要ありません。

3. 3

   どのモデルを利用できますか？

   高速な下書きにはFLUX Schnell、難しい細部にはNano Banana Pro、プロンプト忠実なレイアウトにはGPT Image 2、本番用ビジュアルや複数参照にはSeedream 5.0 Proを使用できます。同じプロンプト欄でモデルを切り替えられます。

4. 4

   画像内に文字を描画できますか？

   はい。ポスターの見出しや商品ラベルの文言など、正確な言葉をプロンプト内で引用符で囲むと、それが画像の一部として描画されます。文字の正確さを求めるなら、Nano Banana ProとGPT Image 2が最有力です。

5. 5

   クレジットの仕組みは？

   生成では、選択したモデルと生成枚数に応じてクレジットを使用します。FLUX Schnell は1枚あたり1クレジットからです。利用可能な残高は常に右上に表示され、不足する場合は生成前にプランを選択できます。

6. 6

   インストールやAPIキーは必要ですか？

   どちらも不要です。モデルは弊社側で動作するため、ダウンロードもGPUもキーの入力も必要ありません。ノートPCやスマートフォンのブラウザからご利用いただけます。
