    LTX 2.3 - I2V T2V Video Reasoning lora VBVR - v4.0 motion I2V Sulphur 2
    NSFW

    This was the first VBVR lora trained for LTX 2.3

    You can make money with my models. Sell what you generate, use it in paid work, run it on paid services, merge it, sell the merge all of it, no permission needed. Credit is appreciated but never required. New releases might have a short early access window behind Buzz, then go free and free is permanent. Once a model is free, I will never re-paywall it or pull it for a paid platform, and you're welcome to mirror, archive, and rehost it so it stays free no matter what happens to any one site.

    Feel free to mirror any of my loras to HuggingFace

    V4 has been trained on Sulphur 2 Base and was trained on 7000 videos with rank increased to 128 to give it more capacity to be able to improve prompt following. Using the distilled 1.1 lora at a strength of 0.5 in wan2gp you can crank steps all the way to 50 which can improve quality of gens. Not required though like it was not required in V3 or below but a nice option to maximize quality if you want. I usually do 10-12 steps. Videos are generated using 10eros since its the version of Sulphur optimized for i2v.

    Wall of text with a bunch of info below

    V3 has been optimized for motion. Expect noticeably livelier, more dynamic movement compared to previous versions. I generated the example videos using the int8/fp8 distilled model using 8 steps in wan2gp. For on site generation the dev model has been reported to be broken, if using on site gen try the distilled one instead! I can highly recommend LTX 2.3 Sulphur 2 base if you are using comfyui and if your using wan2gp use the Sulphur 2 base rank 768 lora https://huggingface.co/SulphurAI/Sulphur-2-base/tree/main

    What changed in V3: Attention-only layers. The feedforward layers have been stripped, leaving only the attention weights. It seems like the prompt following and reasoning behavior most likely live in the attention layers, while the feedforward layers were potentially interfering with natural motion, likely by over-learning features like textures and style from the training data.

    Better motion, smaller file size.

    A LoRA that improves prompt following, temporal consistency, and motion "precision" for LTX 2.3. Reduces the floaty, drifty motion that LTX tends to add to scenes. Things that should move, move with purpose. Things that shouldn't move, move less. Also works on non-NSFW, non-Furry, realistic, animated etc. It responds well to detailed prompts.

    In comfyui or wan2gp lowering image strength to 0.85 can improve motion in general if you want more motion

    Feedback and A-B comparisons welcome. V2 and V1 was trained on 4800 videos.

    Prompting tips in non-nsfw terms so its less confusing just adapt it to nsfw:

    Be specific and literal. Describe what happens, in what order, step by step.

    Instead of "a ball bouncing around" → "A red ball moves to the right, bounces off the wall, and returns to the center"

    Instead of "fluid pouring" → "Water flows from the left container through the connecting tube into the right container until both levels are equal"

    Describe the starting state, the action, and the end state

    The LoRA follows prompts more literally than base LTX — precise prompts will give much better results

    How was it made?

    v0.1 and v0.2 were trained on 360 videos from the VBVR (Very Big Video Reasoning) dataset synthetic task videos where every motion is precise and intentional. No concept bleed, no style change, just tighter control.

    Based on the paper "A Very Big Video Reasoning Suite" which demonstrated this approach on Wan 2.2. I noticed that lora helped prompt following and temporal consistency a ton with wan so I am training this version for LTX.

    What does it actually do?

    Prompt following is more faithful — the model does more of what you asked instead of improvising

    Motion is more deliberate and less erratic

    Reduces random drift and wobble in scenes

    Temporal consistency improved — actions follow logical sequences

    What it doesn't do:

    Doesn't change visual style

    Doesn't add or remove capabilities LTX doesn't already have

    Not a motion LoRA — stacks with motion LoRA's

    Training details for v0.1 and v0.2 (if you give a shit)

    Rank 32

    360 VBVR synthetic videos at 512x512, 81 frames <------Alot less than 1 million but still a shitload to train on this is very slow to train locally.

    LR 1e-4, adamw8bit

    Training details for V1

    Training videos were increased to 4800

    Resolution is the same but frames were increased to 121

    Every other setting the same as v0.1 and v0.2

    More training data from the VBVR dataset was added to v1

    Below is the new dataset I trained on's data composition if your curious

    Tier 1 — Physics and Motion (3,400 samples)

    Core generators at 300 each: G-11 (object reappearance) has a shape move off-screen in a direction and return along the same path — teaches trajectory and object persistence. G-25 (separate object spinning) is a shape that rotates in place then translates horizontally to a target position — multi-step motion sequencing. G-33 (visual jenga) is a stack of objects that get removed one by one from top to bottom — sequential extraction with implicit physics ordering. O-29 (ballcolor) is ball tracking tasks with color — motion following plus identity preservation. O-52 (traffic light) is discrete state transitions, lights switching on/off between green and gray — teaches the model that state changes are crisp, not gradual. O-75 (communicating vessels) is fluid equalizing between connected tubes based on pressure — continuous physics simulation over time. O-87 (fluid diffusion) is ink spreading in water — another continuous physical transformation but with expansion rather than equalization.

    New additions at 250 each: G-35 (hit target after bounce) is a ball with an initial direction that bounces off walls following reflection laws to hit a target — pure trajectory prediction with physics constraints. O-30 (bookshelf) is book rearrangement on shelves — the specific task VBVR highlighted where their model beat Sora 2.

    Multi-step transforms at 160 each: O-7 (shape color change) is a single transformation — shape changes from one color to another. O-8 (shape rotation) is a shape rotating by a specific angle. O-13 (outline then move) is two sequential steps: change a shape's outline style, then move it to a new position. O-14 (scale then outline) is also two steps: scale a shape up or down, then change its outline. These four together teach the model that instructions are ordered and each step completes before the next begins.

    Tier 2 — Spatial and Reasoning (1,420 samples)

    Proven generators at 100 each: G-13 (grid number sequence) is filling in number patterns on a grid. G-17 (grid avoid red block) is pathfinding on a grid while avoiding obstacles. G-31 (directed graph navigation) is finding the shortest path through a directed graph. G-41 (grid highest cost) is evaluating spatial values on a grid to find the optimal path. O-24 (domino chain) is a sequential cascade where dominoes fall until they hit a gap — teaches causal chains and stopping conditions. O-34 (dot to dot) is connecting numbered dots in sequence — ordered drawing. O-47 (sliding puzzle) is tile rearrangement under constraints, like a 15-puzzle. O-83 (planar warp) is warping a grid to align with a target quadrilateral — geometric transformation.

    New reasoning diversity at 130 each: O-1 (color mixing) is RGB additive mixing where two light sources combine and the result fills a target zone — rule-based continuous process. O-33 (counting objects) is exactly what it sounds like — count things correctly. G-3 (stable sort) is arranging objects by a rule while preserving relative order. G-37 (symmetry random) is completing a pattern by mirroring across an axis. O-21 (construction blueprint) is fitting a correct puzzle piece into a gap in a structure. G-44 (BFS) is breadth-first search traversal of a graph — systematic layer-by-layer exploration.

    The overall dataset is weighted roughly 70/30 toward physical motion and transformation tasks over abstract spatial reasoning, All of these are taken from the VBVR dataset I am not the creator of the dataset. I'm pretty new to lora training so if you have tips let me know.

    REMEMBER its not X, its Y.

    You mentioned using 768 LoRA.. Should it be used for distilled Sulphur 2 model? I never used it since I thought I shouldn't. Or should I use it at like 0.5 strength for final pass only?

    betech79209Jun 26, 2026

    Use it with a dev BF16/GGUF in conjunction with Kijai's 1.1 dynamic fro09_rank111 distilled LoRA at 0.60. 30+ steps and a strength of 1.0 for this LoRA. Don't use distilled models with 10Eros/Sulphur as the trained distilled model will fight with the LoRA's. Always use a dev model for NSFW as you will get guaranteed results and not end up with watermark in the process. Some model trainers will try to embed that into the output.

    betech79209Jun 26, 2026

    You can find the 10Eros 768 LoRA through maximsobolev275 on Huggingface.

    Do we use sulphur base 2 Distilled to replicate those previews?

    Also, How do I add that model to Wan2gp?

    unquantized 10eros is what I used. If you drag and drop into wan2gp and use the first frame of the video as your input image, the same seed as the video and the same loras you might be able to replicate it but expect it to not be a 1:1 replica.

    koopa990Jun 20, 2026

    @MisticRain69 Oh i see. do you know how to make it appear in Wan2gp?

    @koopa990 There is a drag and drop for videos near the bottom of the wan2gp tab where you generate videos

    @MisticRain69 as in? I'm referring to how do I use custom checkpoint model in wan2gp

    jazzyreynard285Jun 23, 2026

    @koopa990 There's a button in the top right for finetunes to do that. You download the checkpoint, add it to the chkpts folder, and then select it from that button. You can join Wan2GP's discord for shared finetune templates, or help regarding it. But i suggest you read the github documenation for basic stuff.

    koopa990Jun 23, 2026

    @jazzyreynard285 Alright. so sorry for asking all these questions.

    So, as of now, I finally got a couple of videos out, which I shared on here.

    Also, it seems I cannot get the whole thing to generate NSFW video. Am I doing something wrong? im doing i2v

    So I have noticed with LTX that smearing/ghosting seems to happen when either the image strength is set to high, other loras have their strength set too high or other loras are interfering with each other. The new 10eros model has the least smearing issues but doesn't have the anatomy knowledge Sulphur has. I'm attempting to train a good NSFW multi purpose lora for it with 1200+ videos if its good I will upload it if not I wont.

    Working on a V5 VBVR lora trained on the new Eros model since I noticed these current versions dont perform as they should with his DMD eros model.

    hatt2Jul 22, 2026

    Much appreciated. Looks like LTX overall is getting some noticeable progress after a bit of stagnation.
