Update - V1512 is released: 2/15/2025

I'm doing an early release due to needing at least a few days to develop the captioning software to create the next version iteration; and I simply do not have the time of day.

I'm releasing mostly because of the discovery with Hunyuan, and I'm also releasing a working Hunyuan merge with Simulacrum Schnell that produces very fun stuff... and it really shouldn't.

This version's core features;

• does not require negative prompting

• works with Flux1S models

• works with Hunyuan -> throws some errors just ignore them

• works with the various clip_l_omega versions

Configuration:

Load using the CLIP_24_L_OMEGA for full effect, as this version of Simulacrum Schnell was heavily trained using the post SDXL CLIP_L version.

I'm uncertain if this CLIP_L is the exact same version, but it's definitely pretty similar if it isn't and should work with other versions of CLIP_L omega.

Steps: 12-58 -> 32
CFG: 2.5-9 -> 3.5
DCFG: 0 (flux guidance)

Samplers:
Euler -> Simple
DPM-2M -> Beta/Simple
DPM-2S -> Beta/Simple

Resolutions: 
1308x1308 (really close to this can't remember), very big.
1216x1216, 1216x832, 832x1216
1024x1024
1024x832, 832x1024, 832x832
768x768
512x512, 512x768, 768x512

Yields full ???? depictions upon request. Yields up to 20 characters in alternative locations and positioning.

Full comics on request.

Tremendous amount of outfits, screen control, truncated sectioning, grid control, rotation control, offset control, size control, and even more.

Consult the SDXL-Tag Guide for a full list of trained bbox data.

Interpolative video training data used for 3d and realistic.

Update - V2 is still brewing : 2/6/2025

I've turned up the ???? knob and broke it off. If this thing doesn't produce high grade high complexity ???? I'll be shocked.

It'll probably take another week of cooking to fully reach maturation, so ???? with the time.

Update - V2 is brewing :1/30/2025

V2 will not need a negative prompt. I've been running the same data that I ran through SDXL for an epoch to see what it'll do. It's already starting to take, and the need for a negative prompt is going away rapidly.

It's about 300,000 or so images, roughly a third with plain English prompts.

So either the 5x5 grid will work, or the model will burn to a crisp.

It's attached to CLIP_L OMEGA V4, so be aware it'll behave a little... a little differently than you expect compared to the first version. This CLIP_L is 10 million samples smarter.

I made everything so you can download it while you aren't logged in, so no login validation or keys required to auto-download it.

As of V129 DEPICTION OFFSET works in a substantial way. Experimentation required.

I can officially declare V122 ADVANCED PROMPT GRADE NSFW. You should be able to create the majority of common ???? related acts and detailed situations with the current released version. I fed 1D these exact images in MULTIPLE epochs and it laughed at me.

The further along the training goes, the more plain English depiction it'll be able to handle. Currently this is not a simple process, but you can work it out if you give it a bit of elbow grease.

I'll be writing three articles soon based on using this model, because it's quite different than Flux1D and it's VERY VERY underestimated. The power here is substantial and responsive to training, while Flux1D often fell apart during training.

• Simple Schnell subject fixation using the rule of 3

• Complex scene interactions and careful caption planning for Schnell ???? training

• Prompting ???? interactions and adult depictions with Simulacrum Schnell V1

I guarantee this model is far more powerful than is expected of it, and the outcomes from training are far more powerful than expected. The QUALITY is suffering a bit currently, but the additional training is showing certain traits are most definitely clearing up over time. This is only going to compound when I provide it with more training and more information for the requests.

I STRONGLY advise using "Shuttle 3 Diffusion" Schnell to inference this lora. It amplifies the capabilities a large amount with less prompting. Shuttle v3.1 is okay but doesn't work as well with this lora, it's more compliant with it's own thing.

Standard Flux Schnell FP16 and FP8 depict a FAIR QUALITY with the same settings now that we've hit Epoch 5/10. Many details that Shuttle 3 Diffusion is hiding or replacing with it's own training appeared from the training as emergent traits in standard Schnell, while Shuttle is still hiding the effects. FP8 is a little lesser but not by much. I actually ran the first epoch on FP8 at a higher learn rate for the baeline, so it should respond pretty well with FP8. The additional 4 were on BF16 mixed training however, which makes them substantially more powerful with the BF16 and FP16 versions of Flux Schnell. I haven't tried the BF16 version yet, but I assume it's good.

Schnell FP16 requires a bit of a balancing act with prompts to make the dataset pop out, but it's not too bad. You can usually generate some fair quality stuff with a few tries and some prompt tinkering.

Be sure to use the SimV4 CLIP_L no matter which model you use, as it's required for a proper experience.

You MUST use NEGATIVE PROMPT for the full experience.
