<h1 id="akanezora-anima">Akanezora-Anima</h1> Akanezora is a full Anima DiT fine-tune trained entirely on a single RTX 3060 with 12GB of VRAM using Aozora. It is released both as a usable model and as proof that full Anima DiT fine-tuning can be done on consumer hardware.If you're interested in fine-tuning your own model, the training code is available here: [<a target="_blank" rel="ugc" href="https://github.com/Hysocs/Aozora_SDXL_Training">Aozora_SDXL_Trainer</a>]<h3 id="branch-a-vs-b"> Branch A vs B</h3>Branch A: follows the recommended Anima tuning setup with bell-weighted loss and non-uniform timestep sampling. Branch B: uses my experimental setup with uniform timestep sampling and uniform loss weighting, giving the model more even exposure across the full noise range. In my testing, this improves visual style and composition, but is slower and harder to tune. <h2 id="version-0.55b-preview">Version 0.55b Preview</h2>This is a 55% training checkpoint continued from the 0.5a checkpoint, trained on 15k images using experimental Branch B settings. The dataset consists of 50% Danbooru-tagged images with generated natural language and 50% hand-tagged / natural language-captioned images. During training, text conditioning was split into 90% tags and 10% natural language prompts.While this release is functional, it should be considered a work in progress rather than a finished product. It is being shared early to demonstrate the viability of the training method and to showcase the Aozora trainer’s ability to fine-tune Anima DiT models on low-VRAM hardware. Pros:<ul><li>Reduces unwanted text generation by around 70%, reducing the need for heavy negative prompts.</li><li>More responsive to Danbooru-style tags.</li><li>Slightly more dynamic seed variation due to soft conditioning.</li><li>More SDXL-inclined generation style.</li><li>Better overall composition and prompt feel across varied prompts.</li><li>Improved NSFW output quality.</li></ul>Cons:<ul><li>Some seeds may still closely resemble the base model.</li><li>Lighting effects often need to be prompted directly.</li><li>Still early in training and may hallucinate content.</li></ul><h2 id="0.55b-training-settings">0.55b Training Settings</h2>Base Model: Akanezora V0.5a Training Hours: Unknown (Power went out so it took 2x longer, estimated around 50 hours) GPU Used: NVIDIA GeForce RTX 3060 (12 GB) | Driver version: 32.0.15.9636VRAM Usage: ~11.4GBMixed Precision: bfloat16Batch Size: 1Gradient Accumulation: 4Learning Rate: 6e-6 Timestep: Uniform Loss: UniformOptimizer: Raven[AdamW float32 variant with offloading] | (betas:0.9, 0.999 | eps:1e-08 | Weight Decay: 0.01| Debias: 1.0)Max Train Steps: 201010 (Completed:115282)Current Checkpoint: ~55% through planned trainingTrainable Parameters: - (P: 1,956,405,248 | P Frozen: 6.44% [llm_adapter.*])Soft text cond: ( 0.75 - 1.25)Dataset Size: 15164 Training Resolution: 1152x1152 (Aspect Ratio Bucketed: 864x1536 to 1536x864)VRAM saving techniques: (Momentum offloading, bfp16 mixed precision, pre-caching VAE and text encoders, Gradient Checkpointing) v0.50 settings: bf16 mixed precision, batch 1, grad accum 4, LR 5e-6, Raven AdamW offload optimizer, wave timestep schedule, soft text conditioning 0.75–1.25, 1152 bucketed training from 864x1536 to 1536x864, VAE/text encoder pre-cache, gradient checkpointing, and momentum offloading.<h2 id="recommended-generation-settings">Recommended Generation Settings</h2>Sampler: ER_SDE Scheduler: BetaSteps: 15-50CFG: 3-5Negative Prompt: worst quality, low quality, lowres, score_1, score_2, score_3, blurry, jpeg artifacts Note: <span style="background-color:rgb(26, 27, 30);color:rgb(193, 194, 197);font-family:-apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Helvetica, Arial, sans-serif, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;;font-size:16px">You need to use <a target="_blank" rel="ugc" href="https://huggingface.co/circlestone-labs/Anima/tree/main/split_files/text_encoders">qwen_3_06b_base.safetensors</a><span style="background-color:rgb(26, 27, 30);color:rgb(193, 194, 197);font-family:-apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Helvetica, Arial, sans-serif, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;;font-size:16px"> for text encoder, and <a target="_blank" rel="ugc" href="https://huggingface.co/circlestone-labs/Anima/tree/main/split_files/vae">qwen_image_vae.safetensors</a><span style="background-color:rgb(26, 27, 30);color:rgb(193, 194, 197);font-family:-apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Helvetica, Arial, sans-serif, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;;font-size:16px"> for VAE. <h2 id="model-transparency-notice"> Model Transparency Notice</h2>For transparency, this release includes the training setup and links back to the open-source trainer/code used to create it.

<ul><li>Following the 50% checkpoint, I have transitioned to a more optimized configuration. I determined that the default Anima fine-tuning parameters previously utilized by the Anima base, were suboptimal in my opinion. I have since pivoted to a more primitive SDXL-derivative timestep and loss formula. Early results are promising, showing improved seed uniqueness and composition while successfully retaining the core Anima knowledge base. Additionally, I pruned the dataset from 36k to 15k images to mitigate prompt and Style similarity bleeding.</li></ul>
