Realism_Engine_Ideogram_4 — Ideogram LoRA¶

What it is¶

Realism_Engine_Ideogram_4 is a user-hosted set of LoRA weight files and ComfyUI workflow JSON for local Ideogram 4 inference.

• includes V1, beta, V2, V3, V4, and V5 safetensors;
• its V2 workflow applies the V2 weight through model-only LoRA loaders to Ideogram 4 branches.

Limit: the repository is 21.5 GB, has an empty README, an unknown adapter license, and no hosted inference provider. Treat it as a locally tested community asset, not a documented or commercially cleared Ideogram 4 release.

Development line¶

• 2026-06-11 — Hugging Face project resource recorded for Realism_Engine_Ideogram_4. On 2026-06-11, this development line included a link to a Hugging Face resource for Realism_Engine_Ideogram_4. The dated link establishes an identifiable project resource associated with the line at that time. The available evidence does not establish its release status, contents, training method, or compatibility.

What changed¶

• 2026-06-09 — The repository was initialized and early assets/workflows were uploaded.
• 2026-06-11 — Realism_Engine_Ideogram_V2.safetensors and rei4_v2_workflow.json were added.
• 2026-06-12 — Realism_Engine_Ideogram_V3.safetensors was added.
• 2026-06-14 — Realism_Engine_Ideogram_V4.safetensors was added.
• 2026-06-19 — Realism_Engine_Ideogram_V5.safetensors was added; it is the latest named weight in the visible history.

How to use this¶

1. Check the adapter page before downloading: its README is empty and its license is unknown, so it is not commercially cleared by its own documentation. — https://huggingface.co/RazzzHF/Realism_Engine_Ideogram_4
2. Install the ComfyUI Ideogram 4 components in the documented diffusion_models, text_encoders, and vae folders. — https://huggingface.co/Comfy-Org/Ideogram-4
3. For the documented V2 path, download Realism_Engine_Ideogram_V2.safetensors, import rei4_v2_workflow.json, and point its two ModelOnly LoRA loaders to that exact weight. — https://huggingface.co/RazzzHF/Realism_Engine_Ideogram_4/blob/main/rei4_v2_workflow.json
4. Pin the tested weight and workflow together: V3–V5 are later uploads, but the repository does not document their changes or workflow compatibility. — https://huggingface.co/RazzzHF/Realism_Engine_Ideogram_4/commits/main

Best practices¶

• Keep the V2 tuning scoped to V2: the supplied workflow says 0.50–0.90 is its sweet spot and warns against going above 0.90. — https://huggingface.co/RazzzHF/Realism_Engine_Ideogram_4/blob/main/rei4_v2_workflow.json
• Use both conditional and unconditional Ideogram weights for the intended quality path; the Comfy-Org maintainer says omitting the unconditional branch usually loses quality, while a lower-precision unconditional model can reduce memory use. — https://huggingface.co/Comfy-Org/Ideogram-4/discussions/1
• Use Ideogram 4's structured JSON captions for controlled tests and retain the seed for reproducibility. — https://huggingface.co/docs/diffusers/main/api/pipelines/ideogram4
• Keep commercial use on hold until rights are cleared: the ComfyUI base package is under the Ideogram non-commercial model agreement. — https://huggingface.co/Comfy-Org/Ideogram-4

Superseded by this¶

• None documented as of 2026-09-07: the 2026-06-19 V5 upload does not state that it supersedes V1, beta, V2, V3, or V4, which remain available.

Still unknown¶

• The adapter's training data, training method, intended use, and license are undocumented.
• No release notes, benchmarks, or workflow mapping establish which of V3–V5 should replace V2.
• No first-party Chinese-language documentation or usable independent Chinese operating evidence was found.
• No independent local run was performed; the V2 settings are workflow-author guidance, not a verified recipe for later weights.
