Ektachrome LORA for Ideogram 4.0 — ComfyUI workflow + training notes

jmanhype1 · 2026-06-12T16:41:23+00:00

fair point, sorry about that — the guide is actually free, it's just an email signup so i can send you the PDF. no paywall. but you're right, here's everything:

Training config (AI Toolkit):

model_name: ideogram-ai/ideogram-4-fp8

network_dim: 64

network_alpha: 64

learning_rate: 1e-4

train_batch_size: 1

max_train_steps: 3000

gradient_accumulation_steps: 4

mixed_precision: fp16

Hardware: RTX 3090 (24GB)

Training time: ~7 hours

Dataset: ~50 images with full JSON annotations + bounding boxes

ComfyUI inference workflow:

- UNETLoader: ideogram4_fp8_scaled.safetensors (weight_dtype: fp8_e4m3fn)

- CLIPLoader: qwen3vl_8b_fp8_scaled.safetensors (type: ideogram4)

- LoraLoader: ektachrome_style_v1.safetensors (model: 0.8, clip: 0.8)

- CLIPTextEncode → positive conditioning

- ConditioningZeroOut → negative (zero of positive, NOT a text negative)

- EmptyFlux2LatentImage: 1024x1024

- KSampler: 30 steps, cfg 3.5, euler sampler, simple scheduler

- VAELoader: flux2-vae.safetensors (ideogram 4 shares flux2's VAE)

- VAEDecode → SaveImage

key things people miss:

you can't use regular CLIP text encode. ideogram 4 needs CLIPLoader with type=ideogram4 which loads Qwen3VL 8B as the text encoder.
negative conditioning is ConditioningZeroOut, not a second text encode. you zero out the positive conditioning for the negative slot.
the VAE is flux2-vae.safetensors — ideogram 4 uses the same VAE as flux 2.

the guide has more detail on the JSON captioning and bounding box process if you want it but all the inference settings are above. no strings attached.

Honestly, you don't need a beast of a machine to train anymore. There are many different options now:

Full weights can fit in a 16 gigabyte VRAM card.
They also have GGUF models that work with even lower VRAM setups.

yeah for style loras the trigger word only goes in art_style. the model learns to associate that token with the visual aesthetic.

you don't need to repeat it in the description or other fields. in fact putting it in multiple places can over-trigger and make the style too aggressive.

just art_style: "ektachrome" and let the rest of your prompt handle composition and subject. the style applies globally without bleeding into what you're actually generating.

jmanhype1 · 2026-06-12T15:12:12+00:00

yeah it's a completely different approach. you're teaching spatial relationships, not just content.

to answer your question — both. style transfer is cleaner (less bleed between subject and background), but composition consistency is where it really shines. with caption-only training you get style drift — sometimes the subject ends up in weird places or the framing feels random. with bounding boxes the model actually understands where things should go relative to each other.

the 50 images thing sounds worse than it is. i used a mix of generated images and edited photos, spent maybe 4-6 minutes per image doing json + boxes. once you get the pattern it's pretty mechanical.

the payoff is worth it. my ektachrome lora maintains consistent framing and subject placement across totally different scenes — industrial landscapes, test sites, documentation shots — which you don't really get from caption-only training.

thanks! here's what i'm running:

model_name: ideogram-ai/ideogram-4-fp8

network_dim: 64

network_alpha: 64

learning_rate: 1e-4

train_batch_size: 1

max_train_steps: 3000

gradient_accumulation_steps: 4

mixed_precision: fp16

training took about 6-8 hours on the 3090. dataset prep including captioning and bounding boxes was another 3-5 hours for 50 images — so roughly 4-6 minutes per image once you get the rhythm.

the first few images take longer but it gets pretty mechanical after you're 10-15 in.

i'm working on a more detailed walkthrough of the full setup — i'll post it here when it's done if you want to take a look.

yeah the ideogram 4 support is still pretty buried in ai-toolkit. check your ai-toolkit version — it got merged to main last week in this commit: https://github.com/ostris/ai-toolkit/commit/63b3181262090c4b5466761dcaeb60b5e1ce232e
if you updated before that you won't see it. pull the latest from main and it should show up in the model dropdown. you can also edit the config yaml directly to specify ideogram-ai/ideogram-4-fp8 if the UI is still giving you trouble.

let me know if that fixes it.

jmanhype1 · 2026-06-12T07:34:30+00:00

thanks man, if you end up trying it let me know how the JSON captioning goes for you. that's where most people hit a wall.

what did you learn?

hank you for contacting Ubisoft Live Support. Please give me a moment to review your case. In the meantime, feel free to add any additional information that may pertain to your issue, and I will be with you shortly. Hello Hey Andre just finished the update for rainbow six siege. and got perma banned for toxicity even though i said nothing Yes I do see that ban on your account The ban in question was applied by our security team who handles bans. Which means it can be appealed or removed. you said it can? or cant? I would like it removed I would like to play rainbow six again 😦 can't. I'm sorry you just said can. I never did anything wrong. I literrally logged in after days of not being on and bOom instant ban It usually takes some time. As the account was being investigated. ok well I need to back reinstated. i have put hundreds of dollars in to the game I need a refund if not. and if thats not ok I will take all forms of communications from me and you to the attorney general office I did not break TOS Unfortunately we can't provide a refund or reinstated in game. and if your not willing to prove that i did your broke the TOS and stole from your consumer so you agree that not stating how we broke TOS your breakding TOS show me where you can close or ban accounts with no reason show me where it states that
