Krea2 Turbo-BBox Particle Sliders

Final Boss and Eldritch, with original rank-16 LoRAs and compressed rank-8 distills. Use strength 1 for the calibrated effect. Same prompt, seed and sampler across each comparison.

Built on jimmycarter/krea2-turbo-bbox, epoch-14-step-73184/transformer. These are ordinary attention LoRAs. The originals were trained directly as LoRAs; the distills compress those linear adapters.

Samples

Each comparison shows Off / On (Original), followed by Off / Distill. On and Distill both use strength 1. Click any image to open its full-resolution PNG. All images below are AI-generated, 768 × 768, 8 steps, guidance 0, mu=1.15. Each comparison states its seed and keeps it fixed across Original, Distill and Off. They were rendered from the released files, with no external alpha multiplier.

Final Boss

Robot in a rainy yard

A plain blue service robot gains angular shoulder and chest armor, heavier mechanical limbs and weathered panels. Same rainy factory yard, prompt and seed.

The bridge prompt was excluded from the original six-pair training set, then used for development comparisons. These examples are not a final-test benchmark. The featured Final Boss photograph was visually selected from eight robot photo prompts at strength 1, following an earlier eight-subject photo search. The Tokyo street photo and first workshop robot remain available in the additional examples. The robot selection notes and all eight comparisons and earlier photo search record the curation. The original Eldritch effect emphasizes organic armor and curling appendages; extra eyes and facial tentacles remain weak. The fruit control shows some rendering-style drift.

Downloads

Original files are about 77 MB; distills are about 38 MB. Both contain 128 projection adapters. PEFT originals · PEFT distills · Catalog · File hashes.

ComfyUI

Use standard Load LoRA with a ComfyUI export, MODEL strength 1, CLIP strength 0. No custom node is required. The optional comfy_krea2.py node, Krea2 Turbo-BBox LoRA under NTC/Krea2, also handles these files and the native exports' alpha metadata. Plugin ZIP · Setup.

Use krea2-bbox-turbo-comfy-latest.safetensors with the stock text encoder and VAE from Comfy-Org/Krea-2. Start from the Krea-2 Turbo template: 8 steps, CFG 1.0. The Diffusers equivalent is guidance_scale=0.0. The bbox checkpoint uses the distilled timestep shift mu=1.15.

Diffusers

Use a Diffusers build with Krea2Pipeline and Krea LoRA metadata support. The release validation records the tested versions. After loading the bbox transformer with the krea/Krea-2-Raw pipeline components:

pipe.register_to_config(is_distilled=True)  # selects mu=1.15
pipe.load_lora_weights(
    "ntc-ai/krea2-particle-sliders",
    weight_name="weights/native/krea2-eldritch-unit-alpha.safetensors",
    adapter_name="eldritch",
)
pipe.set_adapters("eldritch", adapter_weights=1.0)
image = pipe(prompt, height=768, width=768, num_inference_steps=8,
             guidance_scale=0.0).images[0]

The alpha is inside the file. For direct transformer.load_lora_adapter calls, use use_safetensors=True so the loader reads that metadata. PEFT users can load the corresponding folder and its adapter_config.json.

Grounded captions use x-first [x0,y0,x1,y1] boxes on a 0–1000 grid, one element per line, numeric character IDs, and panel-contained text. Prompting guide. The actual model tokenizer checked the 507-token content budget before training.

Distillation and alpha

Distills fit output principal components on 480 training activations per projection. Alpha selection uses 16 separate development states and complete denoiser edits. These errors measure approximation, not image quality. Compare the images before choosing a format. Method and all candidate measurements.

The originals retain every learned matrix. Final Boss embeds alpha 16 at rank 16; Eldritch embeds alpha 24 at rank 16, making released strength 1 equivalent to its previous strength 1.5. Student alphas are selected separately. Both formats keep the base's 8-step schedule; this distillation reduces adapter rank, not denoising steps.

Training and source

Both originals used physical GPU 0, rank 16, 400 updates, learning rate 5e-5, 512px, six paired captions, two cached trajectory seeds per pair, and preservation weight 0.1 every fifth update. The base and text encoder stayed frozen. Source, configurations, validation and reproduction belong to krea2-particle-sliders, following the release layout of anima-particle-sliders. The Krea originals are linear LoRAs; this is not the Anima nonlinear particle training recipe.
