| Text to Image (Ideogram v4) | |
| About the model The model is trained on structured JSON captions (scene summary, style block, background, and optional per-object descriptions with bounding boxes and hex color palettes). Official inference validates prompts against that schema. Guidance uses flow-matching with asymmetric classifier-free guidance (the unconditional pass drops text tokens)—not a separate negative prompt string. NOTE: If you see "Image blocked by safety filter" it is because of safety training in the model itself, ComfyUI does not have any safety filter. How to build prompts here (a) Raw input: Paste or type directly into the subgraph. You may use plain natural language, but structured JSON (as in the subgraph default) gives the most predictable layout and style control. (b) Model-assisted (LLM): Use the Ideogram4 Caption Prompt Template output with any LLM tools to obtain the JSON format prompt | モデルについて このモデルは、構造化されたJSONキャプション（シーン概要、スタイルブロック、背景、およびオプションのオブジェクトごとの説明（バウンディングボックスと16進数カラーパレットを含む））で学習されています。公式推論では、プロンプトをこのスキーマに照らし合わせて検証します。ガイダンスは、非対称分類器フリーガイダンス（無条件合格の場合はテキストトークンが破棄されます）を用いたフローマッチングを使用しており、別途否定プロンプト文字列は使用していません。 注：もし「安全フィルターにより画像がブロックされました」と表示される場合は、モデル自体の安全学習によるものであり、ComfyUIには安全フィルターは搭載されていません。 プロンプトの作成方法 (a) 生の入力：サブグラフに直接貼り付けるか入力してください。自然言語も使用できますが、構造化されたJSON（サブグラフのデフォルト設定）を使用すると、レイアウトとスタイルの制御が最も予測しやすくなります。 (b) モデル支援（LLM）：Ideogram4キャプションプロンプトテンプレートの出力を任意のLLMツールで使用すると、JSON形式のプロンプトを取得できます。 |
| Ideogram4 Caption Prompt Template | |
| This is a prompt construction template. You can copy its input into any LLM to generate matching prompts. You may try installing or updating KJNodes and use the Ideogram 4 Prompt Builder KJ node to achieve visual control over prompts. | これはプロンプト作成テンプレートです。このテンプレートの入力内容を任意のLLMにコピーすることで、対応するプロンプトを生成できます。 プロンプトを視覚的に制御するには、KJNodesをインストールまたは更新し、Ideogram 4 Prompt Builder KJノードを使用してみてください。 |
