This workflow is for KJ Structured Prompt FAST Model. It is designed for creators who want to use the Ideogram 4 Fast model in ComfyUI together with KJ Ideogram 4 Prompt Builder, making prompt construction more structured, repeatable, and layout-aware.
The workflow uses Ideogram4-fast_int8-convrot-simple.safetensors as the main model, qwen3vl_8b_fp8_scaled.safetensors as the Ideogram 4 text encoder, and flux2-vae.safetensors as the VAE. The main prompt interface is KJ Ideogram 4 Prompt Builder, which allows the user to build a detailed structured prompt with subject, background, style, aesthetics, lighting, medium, palette, and element-level layout information.
Compared with the Instant version, this FAST workflow is more suitable when the creator wants stronger image quality and a more deliberate render path while still keeping the graph simple. The KSampler uses 20 steps, CFG 1, euler sampler, and normal scheduler. This gives the workflow more sampling depth than the Instant version, making it better for benchmark images, polished posters, ultrawide compositions, and detail-sensitive prompt tests.
The canvas is set to 2048×880, making it especially useful for ultrawide visual generation. The example setup focuses on a Y2K cyber fashion photo with a complete focal subject preserved inside a wide panoramic frame. It tests whether the workflow can keep the character coherent while extending the environment naturally to both sides.

Suggested workflow:
Use this workflow when the Instant version is fast enough for testing but you want a stronger final render. Build the prompt through KJ Prompt Builder instead of writing a loose prompt. Define the main subject, environment extension, lighting, medium, aesthetics, and palette separately. For ultrawide images, pay special attention to side-space detail and subject placement. If the subject stretches or duplicates, strengthen the instruction to preserve the complete focal subject and avoid repeated bodies or distorted anatomy.
