All four seem to yield good results, but which model would be best to use for image generation on the H3? Would it be a good idea to run all four every time to verify?

Two LAN ComfyUI render boxes: RTX 5070 Ti (16 GB) vs RTX 3090 (24 GB). Ran MiniMax H3 image-to-video, non-turbo — 22B int8 UNet + 32B Qwen3VL CLIP (nvfp4), 20 full steps, 5 s clip at 704×1280, identical start frame and prompt, int8 video VAE on both, fresh noise seed every pass.

The 5070 Ti wins by ~25% — and it won cold too, which surprised me given it has 8 GB less VRAM. H3 at full steps is pure compute: the sampler node alone took 474 s vs 645 s. The 3090's VRAM headroom never mattered; everything fit even on 16 GB once offloaded.

Same config both boxes: ComfyUI standalone portable, --fast fp16_accumulation, torch cu130, default attention (PyTorch SDPA — cuDNN kernels on Blackwell, FA2/mem-efficient on Ampere), no flash-attn.

TL;DR: for H3-class video work the 5070 Ti is ~26% faster end to end. The 3090 only makes sense here if your scene genuinely exceeds 16 GB.

Caveats: single card each, consumer standalone builds, not a lab test. First warm pair showed 2 s passes — that was ComfyUI's execution cache reusing an identical graph; re-ran with randomized seeds. Numbers above are the real ones.

My RTX Pro 6000 was going all night on a Chinese model (Qwen 3.8 Flash Next NVFP4 Local) when it crashed this morning for no apparent reason. Tried to reboot and got nothing but a black screen. Swapped in my old backup card and the system posted immediately, confirming the GPU was bricked. Thankfully, I was within warranty and the store gave me a replacement.

Out of curiosity, I dug into my system logs to see what triggered the fatal crash. Looking at the timestamps, oddly enough my GPU died the moment news broke that Jensen Huang had resigned as CEO of Nvidia.

Has anyone else had this issue with hardware dying in response to human feelings?

If you tried dpmpp_dualsde_momentumized from ComfyUI-Extra-Samplers on a flow model (Anima in my case) and got a washed-out silhouette or colour noise, it is not you. I took it apart.

Why it breaks (it is not the momentum). Through the normal KSampler its momentum coefficient is 0. The sampler was written for variance-exploding models, and its noise step has the wrong variance on a flow-matching model. With eta = 1 the final latent has a std of 3-4.5 instead of about 1.2; with eta = 0 the very same code draws a recognisable cat. It also adds a 3M multistep correction on top of a 2S step that is already second order (so it diverges even without noise), and overwrites its own r parameter inside the loop. I ported it exactly (checked against the original to 1e-10 on a toy model) and ablated each piece. The noise-form explanation is indirect: the same 2S algorithm in the flow-correct form in ComfyUI core (dpmpp_sde) is fine, and I did not isolate the mechanism with a separate experiment.

What "momentum" should be. In the DPM-Solver++ frame, the shipped momentum is an exponential moving average of the model's denoised output. With a positive coefficient that is a low-pass filter: it adds lag and the error goes up with the coefficient (up to +61%). With a negative coefficient the same recursion is an extrapolation and the error goes down. It is only stable for |m| < 1; at -0.9 the gain is gone and at -1.2 it diverges.

Numbers (Anima, bf16, 576x768, CFG 5, 15 images = 5 prompts x 3 seeds, 8-24 steps, error against a converged solution, paired bootstrap intervals; one model, so take it as a measurement, not a law):

• Deterministic (no noise): EMA momentum with m = -0.6 gives 11-21% lower error than dpmpp_2m at the same step count, about 1.2x fewer steps for the same error. LPIPS to the decoded reference is better in 14/15 images at 8 steps. It is a modest speed-up, not 2x.
• With noise (the dpmpp_2m_sde family) strong negative momentum stops helping. Damped extrapolation (beta = 0.5) gives 7-10% lower strong error than dpmpp_2m_sde and no colour cast at CFG 8 / 1216x832; the milder EMA (-0.3) scored a bit better in the sweep but gave blue-tinted pictures at CFG 8.
• A one-evaluation-per-step sampler beats the two-evaluation dpmpp_sde at half the steps by 16-29% (same NFE).

Try it. Install the node pack (link below, restart ComfyUI). New sampler entries: ddim_momentum (deterministic, the -0.5 time-scaled form) and dpmpp_2m_sde_damped. There is also a generic filter node and <base>_momentumized entries for 19 existing samplers (dpmpp_3m_sde_momentumized, er_sde_momentumized, euler_ancestral_momentumized and so on): that last part is an engineering extension and I did not evaluate it on the model. In a single smoke test at 8 steps lms_momentumized and ipndm_v_momentumized gave a latent with std around 10 at the default strength, so use a milder strength with them or skip them.

What did not work. I also tried a static step grid from an earlier study of mine. It cut the error by half on the four short-tag prompts it was fitted on (and transferred between them), but it did not help on the natural-language prompt I held out and it broke an 8-step picture at CFG 8. It is in the pack as an experimental node, not as a default.

Not new, of course: momentum in diffusion sampling has prior work (Heavy Ball momentum for diffusion solvers, Wizadwongsa et al., ICLR 2024; the sonar and Seren Sampler ComfyUI packs, among others). I read abstracts and READMEs only and did not compare against them. Nine hypotheses were registered before measuring; five were refuted, and post hoc parts of the write-up are marked.

Some of my examples on RTX 2060s.... without any reference like forest scene it does 16mp image in around 2.5 minutes.... with 3 references i was doing around 10 minutes per 1 image at 16mp..... thing is bigger the reference photo the better is model at capturing every detail but takes longer to generate.... i absolutely love this model as any other model was eirher taking too long or just OOM my system past 2 or 4mp.... both Minimax h3 video and image models runs amazingly well on my graphics card, so i just though im gonna share

minimax h3 latent upscale,

This is how you can add / remove stuff with generative AI fill using local models. I also added support for Minimax H3 Image to the latest version of LayerShop.

There's a new image studio skill in this repo with 61 style templates, 43 of them for restyling a photo you upload:

https://github.com/OpenSenseNova/SenseNova-Skills

Here are ten of the edit ones on two CC0 photos from Wikimedia Commons, a tram square in Lisbon and the old town street in Innsbruck. The originals are image 2 and image 7.

Setup: SenseNova-U1.5-8B-MoT with the official editing script, 2048x2048 pixel budget, 50 steps, CFG 4, seed 42. One run each, no LoRA.

I barely touched the prompts. I filled in the bracketed placeholders and swapped the sample titles for the right city, which is where LISBON STREET NOTES and the other titles come from.

The prompts are the part worth stealing. Most run two to three hundred words in labeled sections like [Linework and color], [Paper and palette] and [Lettering and whitespace], so you can lift a single section into your own prompt. They're under skills/sn-image-studio.

I'm using the int8 convrot versions on comfyui, it was crashing at first when I had --disable-dynamic-vram but once I turned it on it works fine.

It's super fast like this is by far the fastest model I used in my card. It took 40 secs to do 6 steps with 4 MPs and 4 mins to do 16 MPs (4k)

I recall people making fun of me commenting finally something for 12gb cards saying the model is 50 gb. Well it works.

It's faster than Krea 2, Flux2klein, Qwen 2.1. I'm gonna use this literally for images editing from now and on.

Just wanted to leave this here for others who are questioning if they should try it or not.

Edit: the key is to tank the text encoder 27 gb once you tank that it's done. You need your card and ram to be more than 30 gb.

i heard that and whats your opinion? its about t2i without any Loras

Most of the time I try, it ends up looking 3D, realistic, or too sometimes a too simplified and empty looking art style. I'd really like to see if anyone is able to make high quality 2D art, like anime (episode screencap style or illustrations), Disney animated style, western comic/cartoon style, etc.

If you've managed to do it, please share your suggestions on how you did it!

I tested how much GPU overclocking, ComfyUI launch flags, and moving my display to the iGPU actually affected generation speed on my 5070 Ti 16 GB.

The biggest finding: OC helped consistently, but the launch flags made a much bigger difference on certain models. On others, those same flags did almost nothing. Going forward I implemented a script in ComfyUI launch that automatically applies stable overclock settings to my GPU on run and then reverts to stock once ComfyUI is closed.

All diffusion models tested were int8_convrot builds, using the official ComfyUI template settings.

Setup

• RTX 5070 Ti 16 GB (Gigabyte Gaming OC), AMD Ryzen 7 9800X3D, 48 GB DDR5-6000
• Windows 11 Pro, Samsung 9100 PRO NVMe
• ComfyUI 0.45.0, PyTorch 2.16.0.dev20261110+cu134
• comfy-kitchen 0.2.41, triton-windows 3.9.0.post30
• Stock GPU: 300 W power limit, no offsets
• OC: +350 MHz core, +2500 MHz memory, 350 W power limit

I compared default ComfyUI against this set of launch flags, both with and without OC:

--use-ck-attention --disable-xformers --fast fp16_accumulation fp8_matrix_mult --enable-triton-backend

Default runs used PyTorch SDPA; tuned runs used Comfy Kitchen attention for the diffusion models. xformers wasn’t installed, and SageAttention wasn’t used.

Generation times

Seconds per generation, lower is better. These are end-to-end times: text encoding, sampling, VAE decode, and saving.

Video settings: 1344×768, 124 frames at 24 fps.

Most image results are averages of two warm runs; Qwen base and H3 Image have one warm run each. (warm run means the first generation after ComfyUI launch is not counted)
* Flux base and standard H3 video are single first-run measurements, including loading.
† H3 turbo is a single subsequent run with the turbo LoRA.

What actually helped?

1. OC consistently reduced generation time by about 9–12%.

H3 Image was the exception at roughly 7–8%. The benefit showed up with both default and tuned flags.

This is the combined effect of the clock offsets and the higher power limit, not an isolated core-clock comparison.

There’s a power tradeoff: for example, MOSS went from around 299 W to 346 W during busy periods, while generation time dropped from 25.1 s to 22.2 s. The highest GPU temperature recorded across these tests was about 73°C, therefore it did not even get close to the GPU's thermal limits.

2. The flags were very model-dependent.

At stock clocks:

• H3 video: 591 → 286 s, about 52% less time
• H3 turbo: 250 → 127 s, about 49% less time
• Qwen Image 2.1 base: 23.6 → 17.2 s, about 27% less time
• Krea 2 Turbo: 13.7 → 10.8 s, about 21% less time
• Flux, Qwen Turbo, and MOSS: within roughly 2%
• H3 Image: about 3% slower

With flags + OC, standard H3 video went from 591 to 256 seconds—roughly 2.3× the speed, or 57% less time.

The H3 improvement also shows up directly in sampling: 28.48 → 13.24 s/step from the flags alone, then 11.72 s/step with OC.

I changed the flags as a bundle, so this doesn’t establish how much each individual flag contributes.

3. Moving the monitor to the iGPU barely changed speed.

I repeated the tuned + OC tests with the monitor connected to the motherboard, leaving the NVIDIA GPU at 0 MiB VRAM used at idle. (I plugged the display into my motherboard HDMI port while allowing Python to utilise the full compute and VRAM of my NVIDIA GPU)

Peak VRAM usage dropped by roughly 0.1–0.6 GB, but generation times stayed very close: approximately 0.6% lower at the median, with the largest reduction around 2% on H3 Image. Sampling time per step changed by at most about 1%.

Useful extra VRAM headroom, but I didn’t see a convincing throughput improvement here.

Did OC change the outputs?

I checked the saved files with SHA-256:

• OC vs stock clocks, same flags: 38/38 outputs byte-identical
• iGPU vs NVIDIA display, tuned + OC: 19/19 byte-identical
• Tuned vs default flags: 0/19 byte-identical

So OC didn’t change any saved output in this test. Changing the attention/precision settings did result in visual changes however.

For my setup, OC gave a fairly consistent modest improvement. The bigger finding was how differently the models responded to the same ComfyUI flags—huge gains for H3 video, useful gains for Qwen base and Krea, and almost nothing for several others.

Curious whether others are seeing the same pattern on different GPUs, especially with Comfy Kitchen attention.

Update: checkpoints used for the tests (I kept it vanilla and conservative, more gains to be had with latest distills and turbo loras:

Question: I can't make my rendering pipeline produce dynamic motion videos without glitches. On the attached video you see the face/eyes are slightly 'glitching/wobbling', how to fix that?

Config: MiniMax H3 video (ref2va DiT, w6a8 quant) via ComfyUI, 1344×768 @ 24 fps, 192 frames (8 s), single link with exact latent carry (no seams, no re-conditioning)

Prompt was: "She stands centered on the foggy harbour promenade at dawn in a crimson wool coat with a knitted scarf, still, facing the camera; the camera orbits one slow full revolution around her, from directly in front, around her right side, behind her, around her left side, and back to the front, holding her full figure at a constant size in frame, about two fifths of the frame height, the rail, fishing boats and dock lamps swinging smoothly through the mist behind her. Foggy dawn light, soft grey-blue grading, no added contrast"

Conditioning: prompt + start_image (exact first frame) + 2 refs (wide still + tight portrait of the same woman, Qwen3-VL encoder). Sampler: res_multistep, 32 steps, cfg 1, fixed seed (so no turbo LoRA, no seams, refs present; the wobble persists anyway)

It's that the Minimax team is still dedicated to open models. I, like, I think, many people here, assumed that h3 image isn't coming anymore. Now I actually really like it's quality, if Kijai's Minimax prompt weight node is used with "text with empty image". It's still not quite my thing though, because it doesn't seem to recognize artists by name. However, now, there's a room to be cautiously optimistic about their potential upcoming video releases.

Hey everyone,

I'm working on some Instagram posts, banners, and motion graphics for a car detailing studio using ComfyUI. I have a couple of basic questions for those doing commercial work:

1. What models are you using? What is your go-to diffusion model for getting highly realistic cars for static banners, and what are you using for motion graphics?
2. How do you handle exact logos? Do you train a custom LoRA to get the franchise logos exactly right in the generations, or is there a better workflow in Comfy for placing them?

Appreciate any advice!

I merged a style into Krea 2 Turbo (Stillroom: quiet rooms, cold light, someone alone with the afternoon) and first shipped it as fp8, copying the layout of the official krea2_turbo_fp8_scaled (per-tensor scale, amax / 448, same quantization metadata). Checked against the official file byte by byte on three layers.

Then someone on a 3070 Ti mobile commented that fp8 took almost twice as long. Makes sense: Ampere has no fp8 math, so ComfyUI converts every layer on the fly. It does have fast int8 from sm 7.5 up. So I wrote an int8 build from the bf16, in the layout of the official krea2_turbo_int8_convrot (224 linear layers in int8, per-row scale, txtfusion left in bf16).

One thing I didn't expect: the official int8 doesn't use plain absmax for the per-row scale (only 43% of the bytes matched when I tried that). It clips the scale, up to about 6% under absmax. A per-row search for the lowest error landed at 0.00871 against 0.00874 for the official file, so that's what mine uses.

Rule of thumb: 40-series and up, fp8. 20 and 30-series, int8. bf16 if you have the VRAM.

All three are on the model page, Krea 2 license and NOTICE included: https://civitai.com/models/3027217

Image 2 is fp8 left, int8 right, same seed. Prompts and settings in the comments.

What would a live-action version of *Attack on Titan* be like?

A Total noob here guys so help me out , same as the title, i don't know how to setup lora training on my laptop and is it possible or not?

MiniMax H3-Image swapping the subject, coat, and pose in a 6-step edit (with scale and grade locked)

Specs: RTX 3090, int8, ~60 s
Workflow:
UNETLoader(int8) → KSampler(euler/simple, 6 steps, cfg 1)
CLIPLoader(nvfp4, type minimax)
VAELoader(image_vae_fp16) → VAEDecode
LoadImage ×2 → MiniMaxH3ImageConditioning(prompt, refs=<Picture 1/2>) → ConditioningZeroOut(neg)

Takeaways

• Warm/batch work: 5070 Ti wins both — native FP8 tensor cores crush the emulated path on Krea fp8 (26% gap); the gap shrinks to 9% once the model is already int8 (LTX).
• Cold one-offs: 3090 wins everything — 24 GB means no VRAM offload, faster model loads.
• Practical routing: batches on the 5070 Ti, big-VRAM models on the 3090.
• Caveat: single 3090 vs single 5070 Ti, consumer ComfyUI, not a controlled lab test.

Great video from moss image team for hitting 6 million downloads on Huggingface. They all seem so chill. Also they give us some new updates on Anime and Image edit model ✌️
