Four Anima 2.9B Derivatives on M1 Max With a Character LoRA Remapped to 40 Blocks, All Kept the Hairstyles but Took About 1.4x as Long as Base

IkesanContents

While putting together the October 2026 list of the latest Anima derivative checkpoints, I found that four of the derivatives from my June list now have 2.9B versions: Nova Anime AM, CottonAnima, AMIXA, and JANIMA.
My character LoRAs (small adapter weights that make a model draw specific characters) are trained on Anima-Base v1.0, whose DiT (the diffusion transformer that draws the image) has 28 blocks. The 2.9B models have 40.
On plain Anima-2.9B, the characters came out after I remapped the LoRA, that is, rewrote the block numbers in its key names to match the 40-block layout. The question was whether they would still come out on the derivative 2.9B models.
I generated images with the four latest versions on an M1 Max 64GB in ComfyUI, using the same prompts, seed, and LoRA as in the Turbo v1.1 and Aesthetic v1.1 comparison.
The seven 2B versions from the same list are covered in a separate article on the 2B versions.

Models and Basic Information

I tested the four models in the list’s table of “current versions (2.9B) of the derivatives from the June list.”
Only Nova downloaded through the Civitai download API without logging in. The other three returned HTTP 401 (authentication required) without an API key.
CottonAnima 2.9B_v1 has a mirror of the same file on Hugging Face (diffusionmodels1254ani/cottonanima_29BV1_bf16). Its SHA256 hash matched the value listed on Civitai, meaning it is the same file byte for byte, so I downloaded it from there. I downloaded AMIXA2.9B and JANIMA from Civitai in a browser and checked their SHA256 hashes the same way.

Here are the parts of each author’s description that relate to these results.

ModelAuthor’s Description
Nova Anime AM v6.0Built from Anima Base v1.0 + Aesthetic v1.1 + 2.9B. Improved prompt and context handling
CottonAnima 2.9B_v1Anima-2.9B merged with a style LoRA trained on 160 AI-generated images. Diversity drops in exchange for a fixed style. The author says to install the ComfyUI-Anima-2.9B custom node
AMIXA2.9B 2.9B_V01A merge of Anima-2.9B. Uses the coloring of the Illustrious family (SDXL-based anime models) and sharpens character details. A bf16 version bundling the VAE and text encoder is also available
JANIMA v1.0 2.9BFine-tuned from anima-base-v1.0. For the 2.9B version, the author says the new 2.9B layers were merged in to keep 2.9B’s knowledge

Baseline and Generation Settings

The baseline is Anima-Base v1.0 at 30 steps. I reused the images from the Turbo v1.1 and Aesthetic v1.1 comparison and did not regenerate them.

Some of these models recommend Euler a or DPM++ 2M, but I kept er_sde for all of them so the results are comparable.

EnvironmentDetails
MachineM1 Max 64GB
ComfyUISet up a separate v0.33.3 instance (a version that loads 40 blocks natively). The Base images come from the October 21 article, so the ComfyUI version differs

When I opened the Nova file, the DiT had 40 blocks, numbered 0 to 39.
The character LoRA was trained for Anima-Base’s 28 blocks, so I used the remapping script from the article on applying existing character LoRAs to Anima-2.9B to shift the block numbers to their positions in the 40-block layout. Of the 948 keys, 840 were remapped, and the 108 keys for the text-side adapter were left as they were.
ComfyUI’s log showed no warnings about LoRA keys that failed to load.
CottonAnima, AMIXA2.9B, and JANIMA also have 40 blocks numbered 0 to 39, and the same remapped LoRA loaded on them without warnings. For AMIXA2.9B, I used the fp16 DiT-only file instead of the bf16 all-in-one file. Anima uses Qwen3 0.6B as its text encoder. JANIMA’s page also distributes one, but its SHA256 matched my local qwen_3_06b_base.safetensors, so I used the same one as the other models. I did not install the custom node the CottonAnima author asks for and loaded every model with the standard loader in v0.33.3, so CottonAnima was not run in its author’s recommended setup.

Default Style

I generated a blonde character in a white robe without the character LoRA.

The negative prompt is the same as Test 1.

Character LoRA

I applied the character LoRA trained on Anima-Base.
Kana-chan’s identifying features are brown hair, an ahoge (a single strand of hair sticking up), a side ponytail on the viewer’s right, a blue scrunchie, brown eyes, and a white shirt with a red tie.
Kei-chan’s features are long blonde hair, blunt bangs, side braids, a blue hair ribbon in the back, blue eyes, and a red ribbon tie at the neck. She has two ribbons, and only the hair ribbon is blue.

Kana-chan

I generated a full-body standing pose.

Nova Anime AM v6.0Hair and eyes appear. The tie becomes a thin red ribbon in the full-body image and a red bow in the portrait
CottonAnima 2.9B_v1Hairstyle and eyes appear, but the scrunchie is pink in the full-body image and purple in the portrait. A red bow at the neck in the portrait
AMIXA2.9B 2.9B_V01The features appear. The scrunchie is bluish purple. A thin red ribbon at the neck in the full-body image, a red bow in the portrait
JANIMA v1.0 2.9BAll features appear. A thin red ribbon at the neck in the portrait

With the remapped LoRA, all four rendered Kana’s hairstyle as the right character.
Only CottonAnima turned the scrunchie pink or purple, in both the full-body image and the portrait. In the two-character image, it came out blue.

Kei-chan

I generated a full-body standing pose.

Nova Anime AM v6.0The hair appears, but the ribbon at the neck turns navy
CottonAnima 2.9B_v1The hair appears, but the ribbon at the neck turns navy
AMIXA2.9B 2.9B_V01The hair features appear. The ribbon at the neck is red in the full-body image and navy in the portrait
JANIMA v1.0 2.9BThe hair features appear. The ribbon at the neck is red in the full-body image and navy in the portrait. A navy blazer in the full-body image

All four also rendered Kei’s hairstyle.
None of them kept the neck ribbon red in both the full-body image and the portrait. AMIXA2.9B and JANIMA had it red in the full-body image and navy in the portrait.
Nova and CottonAnima turned it navy or blue in both images, the same as official Turbo v1.0 and v1.1 in the October 21 article. The prompt’s blue ribbon is meant for the hair ribbon, but it may be pulling the neck ribbon’s color too, but with a single seed-42 image per model, I can’t tell that apart from random variation.

Prompt (Kana & Kei)

Kana full body

masterpiece, best quality, safe, 1girl, solo, kanachan, brown hair, side ponytail, ahoge, brown eyes, school uniform, full body, standing, looking at viewer, white background, simple background

Kei full body

masterpiece, best quality, safe, 1girl, solo, keichan, blonde hair, long hair, blunt bangs, blue ribbon, blue eyes, school uniform, full body, standing, looking at viewer, white background, simple background

For the portraits, I replaced full body, standing with upper body, portrait and added full body, knees, feet, lower body to the negative prompt.

Negative

worst quality, low quality, blurry, lowres, jpeg artifacts, bad hands, bad anatomy, fused fingers, fused legs, fused limbs, extra arms, extra legs, conjoined twins, deformed face

Two Characters

Instead of a pose with physical contact, I placed them side by side with standing side by side, full body.
I also added English sentences to the prompt describing who stands on which side and each character’s appearance.

Anima-Base v1.0
Anima-Base v1.0 Kei-chan and Kana-chan standing side by side, full body, seed 42

ModelWhat the Image Shows
BaseKei on the left, Kana on the right, and Kana’s ahoge does not show up on Kei. Kei has a red ribbon, Kana wears black tights
Nova Anime AM v6.0Same separation and ahoge. Kei has a navy ribbon, Kana wears black tights
CottonAnima 2.9B_v1Same separation and ahoge. Kei has a navy ribbon, Kana has a blue scrunchie and a red tie
AMIXA2.9B 2.9B_V01Same separation and ahoge. Kei has a thin red ribbon and a plaid skirt, Kana has a red tie and black tights
JANIMA v1.0 2.9BSame separation and ahoge. Kei has a beige vest and a red bow, Kana has a red tie and black tights

All four kept two separate characters on the left and right, and Kana’s ahoge did not show up on Kei. AMIXA2.9B and JANIMA also kept Kei’s ribbon red.
In the 2B article, RDBT, one of the 2B derivatives, grew the scene to four people, but none of the four 2.9B models added extra characters.

Prompt
masterpiece, best quality, safe, 2girls, multiple girls, two different girls, kanachan, keichan, standing side by side, full body, looking at viewer, smile, school uniform, keichan on the left has long blonde hair with blunt bangs and a blue ribbon, kanachan on the right has brown hair with a side ponytail and an ahoge, white background, simple background

The negative prompt is the one from Kana and Kei with 1girl, solo added.

I seated Kana-chan by the window of a café.

CottonAnima 2.9B_v1Holds a cup in both hands. A window, two potted plants, a bookshelf, a ceiling lamp, a picture frame, a chalkboard. A signature-like scribble in the lower left
AMIXA2.9B 2.9B_V01Holds a cup, with a second one on the table. A window, curtains, a potted plant, a bookshelf, a teapot on a shelf
JANIMA v1.0 2.9BHolds a cup to her mouth, with a second one on the table. Four potted plants, a bookshelf, cups on a shelf

All four filled the background down to bookshelves and potted plants, with about as much detail as Base.
Nova, AMIXA2.9B, and JANIMA drew a second cup on the table besides the one in her hand, so the single word teacup produced two cups.

Prompt

Image-to-Image (i2i)

As in the April WAI-Anima article, I ran a source image made with WAI-Illustrious v160 + the Kana-chan LoRA through image-to-image (i2i) at denoise 0.5. Denoise sets how strongly the model redraws the source, from 0 (unchanged) to 1 (ignore the source), so 0.5 is a middle setting.
The source image used the Kana-chan LoRA, but no character LoRA was applied to the Anima models during i2i.

AMIXA2.9B 2.9B_V01Composition kept, a white hood added. The background turns pale pink
JANIMA v1.0 2.9BComposition kept, a white hood added. The background turns pale pink

All five models, including Base, kept the composition, the gold circle, and the sash knot from the source image. What changed was the pattern inside the circle, the white hood, and the background color.

Prompt
masterpiece, best quality, safe, 1girl, solo, brown hair, side ponytail, ahoge, brown eyes, white robe, gold embroidery, capelet, gold sash, long sleeves, long dress, standing, looking at viewer, full body

The negative prompt is the same as in Default Style.

Generation Speed

These are the seconds from when the generation script submitted a job to when it received the image, on the same M1 Max 64GB.
Test 1 is the first image for each model and includes model loading. The Base numbers come from the October 21 article.

JANIMA v1.0 2.9B30371.5 s371.4 s297.1 s

The four 2.9B models took about 1.4 times as long as Base at the same 30 steps, and all four took nearly the same time.
When I measured plain Anima-2.9B in August, it was also about 1.4 times slower at 30 steps, a similar ratio.
That said, the ComfyUI versions also differ, so I can’t say the gap comes from the block count alone.

Which One for What

Assuming you apply a Base-trained character LoRA, here is how these seed-42 outputs split by use case.
