The V2 update to the physics lora. Lora weight 0.7 is recommended. Improves object interaction and motion
Creator notes
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 V2: Retrained from the ground up using 10eros LTX 2.3 NSFW model as the base. Audio seems to be mostly fixed now but its quieter than baseline LTX for some reason. See the example videos to get an idea. Its not bad but not perfect. The object-to-object interactions in V2 should be noticeably improved over V1. I suggested using 10eros as your LTX model since that is what its trained on. I suggest using it at a strength of 0.7 and experiment with other strengths if needed. The workflow I use is . I used LTXVImgToVideoInplace node strength of 1.0 for the videos. PhysLTX is a Lora that improves LTX's understanding of how objects should interact. Characters and objects show better impact, bounce and interaction physics. It reduces the weightless and floaty interactions objects and characters in LTX have with each other. If a character or object interacts with another it should noticeably be more grounded and have a sense of impact and friction. Trained on 2000 videos from the Yes this works the same for realistic and non NSFW generations as well It responds well to normal prompts and prompts that describe impact and momentum. I use it at a strength of 1.0 but that can impact the audio quality for some reason, if you have audio quality issues lower the strength to around 0.7 or use a node to disable the audio influence from the Lora.

7,000°
Floor
The scale runs from 0° to 9,999°. Everything below 7,000° is kept for models no source reports on yet, which carry a stand-in number there so lists stay complete. 7,000° is where measured data begins: a model with real data but almost no downloads sits at the floor, and the measurements fill the degrees above it. The floor says nothing about the model; only the degrees above it do, and they are what separates one model from another.
+1,158°
Civitai downloads
6,302 downloads of this exact version on Civitai. Downloads are the heaviest ingredient and are counted on a log scale: ten times the downloads adds the same 300°, so a model with a million downloads is not a thousand times hotter than one with a thousand. The six download sources share that one term, split between them in proportion to their counts.
+376°
Likes
320 likes and thumbs up across the sources. A like weighs half a download, on the same log scale.
+69°
Adoption rate
About 7 downloads a day, measured between two readings of the sources, never guessed from a lifetime average. Speed weighs a quarter of the download term, so a fresh surge shows without letting a one-day spike outrank years of use.
+100°
Family boost
+100° because this is a LoRA of a family this site is nudging forward right now. It is a bounded nudge inside the score and is listed here openly; it can never hide a model or outweigh a thousandfold difference in downloads.
−159°
Age
−159° because the Ltx2 weights came out in 2025. Every model inherits the age of the weights it is built on: 150° a year, up to 750°, and it keeps growing until then. Without it the top of the list would be 2022 and 2023 checkpoints on the strength of downloads that had years to pile up.
Show detailed breakdown
Every number on this site can be checked. This model's heat score is 8,544°, and here it is built one ingredient at a time, with the running total after each: the floor, the degrees each source adds, the bonus for the kind of model and what the age of its weights takes away. The colors are the bands of the chart above. The glossary at the end defines every term.
  1. 1
    Start at the floor.
    Why 7,000° and not zero: the scale runs from 0° to 9,999°, and the part below 7,000° is reserved for models no source reports on yet, which carry a stand-in number there so the lists stay complete and never outrank a model with data. 7,000° is where measured data begins. A model with real data but almost no downloads sits here; everything that follows is measurement, and the room above the floor holds ten tenfold steps in downloads at 300° each. The floor is the same for every model, so it decides nothing; the degrees above it do.

    8,544°
Glossary: the terms used here
Heat score
One number for how much a model is used and wanted right now, from 0° to 9,999°. Every list on this site that says hottest is sorted by it and nothing else.
Floor
The 7,000° every model with real data starts from. The scale runs from 0° to 9,999°; the part below the floor is reserved for stand-ins (models without data), so that a model with data always ranks above one without. The floor is the same for everyone and decides nothing; the degrees above it are the measurement.
Download-equivalents
Everything the score treats as a download, added up: downloads themselves, each torrent seeder as 1,000, each AI Horde image and each run on a generation site as one.
Log scale
Counting by tens, not by ones: going from 1,000 to 10,000 downloads adds the same degrees as going from 10,000 to 100,000. It keeps giants from crowding out everything else.
Likes
Thumbs up and likes from every source, worth half a download each on the log scale.
Adoption rate
How many downloads a day a model gets right now, from the difference between two readings of a source. A quarter of the weight of the download term.
Measured and estimated
Measured means two readings of a source exist and the difference is real. Estimated means only today's total is known and the past is spread over the model's life; the site says which one it is showing.
Seeder
Someone who keeps a copy of the weights online for others to download over a torrent, or a hosted mirror doing the same. Each one counts as 1,000 downloads.
AI Horde
A volunteer network that generates images for free on donated computers. The number of images it has made with a model is public, and each counts as one download.
Generation sites
Sites that host their own copies of a model and let people generate with it, such as PixAI, SeaArt and Yodayo. Their downloads count like Civitai's and each generation run as one download.
OpenRouter tokens
A text model served through an API, such as Claude or GPT, has no weights to download, so its usage is measured in tokens: the pieces of text it read and wrote through OpenRouter, a gateway many apps use, over the last 30 days. Every 10,000,000 tokens count as one download. Source: OpenRouter (openrouter.ai/rankings), CC BY 4.0.
Full model (checkpoint)
The weights themselves, the file that generates on its own. It gets a bonus because add-ons depend on it.
LoRA and embedding
Small add-on files that steer someone else's weights toward a style, a character or a concept. They cannot run alone.
Family and weights
The base a model is built on, such as SD 1.5, SDXL, Flux or Wan. Every model inherits the release date of its family's weights.
Age
Degrees taken off for how long ago the family's weights came out: 150° a year, up to 750°. It keeps old downloads that had years to pile up from freezing the top of the list.
Family boost
A small, bounded nudge for LoRAs of a family this site is pushing forward right now, always listed in the breakdown.
Stand-in score
A stable number below the floor given to a model no source reports on yet, so lists stay complete. It never ranks above a model with data.
New! (grace period)
A model less than 7 days old shows New! instead of a score and holds no place in the rankings. Its score is computed from day one, but a model one day old grows faster than anything, so without the wait the week's #1 would always be whatever came out yesterday rather than what held up for a week.
Trend
How a model's growth over a period compares with the typical model's growth over the same period. Faster than typical reads as a rise, slower as a fall.
Typical model
The middle of the catalog: half the models with a figure grew faster over the period, half slower.
How this model's popularity has moved against the rest of the catalog: its growth in downloads, likes and usage over each period, measured against the typical model's growth over the same period, with its heat score at the time. Above the typical growth reads as a rise, below it as a fall. The past is reconstructed from today's totals, the model's first day and its measured download speed where two readings exist; a model that did not exist at the start of a period shows n/a.

[VISUAL] Use the current attached image as the exact first frame. The same clearly young adult, age 21, retains the same pale face, long black hair with bangs, dark eye makeup, black lipstick, septum piercing, black choker, body proportions, black top pulled beneath her exposed breasts, fishnet sleeve, shiny black ruffled vinyl skirt, black thong pulled aside, black nails, and the same reclined pose on the black leather couch with both hands supporting her breasts and her legs spread. The dark room, wall posters, purple string lights, warm lamp, and slightly high portrait composition remain unchanged. This is one continuous locked portrait shot from the same frontal viewing angle, with no cuts or angle changes. All speech exists only as synchronized audio. The image remains clean and unobstructed throughout; the lower third contains only the original scene with no graphic overlay. At first, from the exact starting pose, BBWBOUNCE, she stays seated on the couch and begins slowly lifting and lowering her breasts one at a time with her hands, teasing with individual up-and-down motion while her hips, legs, and seated position stay planted. She takes a short breath, looks toward the camera, and moves her lips naturally in sync with the first brief spoken phrase. Then she cups both breasts together and plays with them once, squeezing them toward the camera. Her right hand then slides down her torso toward her exposed pussy while her left hand stays on her chest, her legs remain spread, and contact stays physically connected. She takes another short breath, looks toward the camera, and moves her lips naturally in sync with the second brief spoken phrase before any rubbing begins. During the final seconds, after that second phrase ends, her right hand reaches between her thighs and she slowly, rhythmically rubs her wet pussy with circling strokes while her left hand remains on her breast and her breasts show only subtle natural recoil. She looks down at her pussy, then back at the camera with a focused, aroused expression as the rubbing settles without a position change. Nipple and areola count, shape, size, orientation, and anatomical position remain consistent from frame to frame, moving naturally with the same body surface without morphing, duplication, displacement, or flicker. From first frame to last, she retains the same identity, anatomy, limb count, body proportions, clothing, surroundings, lighting, and relative position. [SPEECH] You like these big juicy tits don't you daddy? Do you also like my tight wet pussy? [SOUNDS] Soft neutral General American young-adult woman’s voice, warm, gently breathy, relaxed, and close-mic. The first short phrase is heard during the breast-tease motion. Quiet breathing follows. The second short phrase is heard after she cups her breasts and before she starts rubbing. Soft fabric rustle and subtle skin movement accompany the breast motion. Later, soft wet rubbing, a low moan, a breathy hmm, and quiet room tone stay synchronized with her hand. No additional speech, narration, ad-libbing, mumbling, continued speech, voice switching, shouting, or music.
