ideogram-4-GGUF — Ideogram 4¶

What it is¶

ideogram-4-GGUF is a pair of Q4_0 GGUF weights for the main and unconditional diffusion components of Ideogram 4.0, built for local runs instead of the API.

• Base model: Ideogram 4.0, 9.3B DiT.
• Runtime: stable-diffusion.cpp.
• Dependencies: Qwen3-VL-8B-Instruct in GGUF and Flux2 AE VAE.

The main Q4_0 file takes 5.64 GB. This is neither an official Ideogram checkpoint nor a ready ComfyUI setup.

It works for a CLI experiment with stable-diffusion.cpp. For reproducible production, verify the exact versions of all four components and the base model license.

Development line¶

• 2026-06-11 — Ideogram 4 GGUF repository linked on Hugging Face. Q4_0 GGUF conversions of two diffusion components of Ideogram 4.0 for stable-diffusion.cpp.

What changed¶

2026-06-11 — The link records the availability of leejet/ideogram-4-GGUF: Q4_0 GGUF conversions of two diffusion components of Ideogram 4.0 for stable-diffusion.cpp.

How to use this¶

As of 2026-06-11, practitioners can use the linked Hugging Face repository as a candidate source for Ideogram 4 GGUF artifacts, while independently verifying its files, license, provenance, and runtime compatibility before use.

1. Download both linked Q4_0 files: conditional ideogram4-Q4_0.gguf and unconditional ideogram4_uncond-Q4_0.gguf. — https://huggingface.co/leejet/ideogram-4-GGUF
2. Build or download compatible sd-cli from stable-diffusion.cpp; the project claims support for Ideogram4 and GGUF format. — https://github.com/leejet/stable-diffusion.cpp
3. Pass both diffusion files, the GGUF version of Qwen3-VL-8B-Instruct, and flux2_ae.safetensors into sd-cli; the prompt must be valid JSON following the model card example. — https://huggingface.co/leejet/ideogram-4-GGUF

Best practices¶

• Write structured JSON prompts instead of plain strings, because the source pipeline was trained on and validates that schema. — https://ideogram.ai/blog/ideogram-4.0/
• Pin runtime versions and all dependent weights, because stable-diffusion.cpp explicitly warns that CLI options and APIs change often. — https://github.com/leejet/stable-diffusion.cpp
• Check the original Ideogram 4.0 license before commercial use, because the GGUF card inherits it rather than setting its own. — https://huggingface.co/leejet/ideogram-4-GGUF

Superseded by this¶

• 2026-06-03 — No local GGUF variant existed before Ideogram 4.0; the official base release provided open FP8 and NF4 weights, but not this third-party GGUF package.
• 2026-06-04 — The assumption that Ideogram 4 cannot run in stable-diffusion.cpp is obsolete; the runtime announced support for Ideogram4.

Still unknown¶

• No independent dated primary source confirms the publication date of the GGUF conversion for the 2026-06-11 event: the public model card reflects repository state, while the Hugging Face profile shows an update on 2026-06-07.
• Exact hashes, current stable-diffusion.cpp compatibility with these files, and output quality relative to the original FP8 and NF4 weights remain unverified.
• The official 2026-06-03 release of Ideogram 4.0 and the third-party GGUF package are separate entities: the former released the base model, and the latter converted it for a specific runtime.
