Anima Delta Mix 3.8B Qwen 3.5

ATTACH V2

A new function in the node pack. Built to raise the influence of Qwen 3.5 4B. It needs a little more memory than the old method. Direct development of Delta Qwen 3.5 4B. Source: Anima 2B — Qwen 3.5 4B Text Encoder.

This model has two modes. Both are selected in the new Clip loader.

3.8 1.1 base — the old mode, unchanged.

Qwen 3.5 strong — new. Slightly better frame reading, better scene layout. Test it.

Important: strong is still a test mode. It has its own problems, and a number of them are already known. If you hit one yourself, or have a fix in mind, write it in the comments.

Delta Mix 3.8B Qwen 3.5 - v5
Same line. v5 is the Attach V2 runtime. The bake is still DiT only. The Semantic Connector is still a sidecar, not inside the file.

The working path is the earlier one: 3.8 1.1 base, full frame. Same sidecar, same official connector path, same picture. If you only want what the previous version already did, stop here.

qwen 3.5 strong is the other CLIP format. It makes Qwen 3.5 4B the leading CLIP. Native 0.6B stays in the graph. This format does not use the 2560 sidecar as the conductor.

Samplers: dpmpp_2m / euler_a / res_multistep Schedulers: res_uniform / normal / beta

Warning

Attach V2 is not stable when you switch CLIP format on one live load. The problem is known. Part of it cannot be fixed in this node without breaking the path.

If the frame smears, drifts, or ignores the format you just set: change the loaded model, then load this checkpoint again, then set the format you want. Do not keep switching base / strong on the same load.

Delta Mix 3.8B Qwen 3.5 - v4

A recut of the same line, not a new family. v3 tightens frame stability and edge clarity: lines and object borders stay even instead of swimming. Same dual brief — human and furry.

Samplers: dpmpp_2m / euler_a / res_multistep
Schedulers: res_uniform / normal / beta

Delta Mix 3.8B Qwen 3.5 - v3
Anatomy and hands: fewer collapsed fingers and joint errors on the same test prompts.
Q35 path: the base holds pose / crop more steadily when the 4B encoder is in the graph. Stem (W): replaced. W is now a custom assembled 2B stack, not the previous floor.

Delta Mix 3.8B Qwen 3.5 - v2

Anima 3.8B mix for the official v1.1 chassis and Qwen 3.5 Connector v2.

Source: CircleStone Labs / lylogummy Anima 3.8B v1.1.

This bake fills W + Gen-1 + Gen-2 (Delta Mix overlay).

Connector v2 and the Q35 watch slots stay as in v1.1.

Qwen 3.5 is attached from a sidecar, not baked into this file.

Cleaner image than v1. Fewer W / Gen-2 clashes.

Fine detail and extra fingers still slip — for v3.

Delta Mix 3.8B Qwen 3.5 -v1

Anima 3.8B mix for the official v1.1 chassis and Qwen 3.5 Connector v2.
Source: CircleStone Labs / lylogummy Anima 3.8B v1.1.

The DiT is a Delta Mix overlay (stem + light Gen-1). Gen-2 insert slots and the Connector stay as in v1.1. Qwen 3.5 is attached from a sidecar, not baked into this file.

Restart ComfyUI after the three packs.

comfyui-anima-3-8B is the official runtime (4B loader + Connector class). Without it the Q35 graph will miss nodes.

Graph

UNETLoader                  this bake (~7.3G)
  → DeltaMix Q35 Attach V2  sidecar on 3.8 1.1 base
CLIP Loader V2              clip_format
  → DeltaMix Q35 Prompt V2  CLIP 0.6B + CLIP 4B
       expanded → CFG / Sampler

LoRA (optional):

UNET → DeltaMix Q35 LoRA → Attach V2 → Prompt V2

Prompt Dual Delta: pos = quality tags + scene, neg = negative tags only.
Use expanded for sampling. native is 0.6B-only.

Extract once: DeltaMix Q35 Extract Connector on anima38B_11.safetensors. Do not extract again unless v1.1 changes.

This file does not include the Connector (~1.2G) or the 4B encoder.
Do not load *Q35bundle in this graph. Bundles are for the official v1.1 loader.

Sampler

Same stack as the v1.1 graph: RandomNoise → CFGGuider → SamplerCustomAdvanced + BasicScheduler. A plain KSampler is fine if the numbers match.

Steps 40. CFG 6. Denoise 1.0.
Sampler: er_sde, Euler, or whatever you already run on 3.8.
Scheduler: normal for this mix. beta if you want the stock v1.1 cadence.

Empty latent 1024×1024. 1920×1080 is stable.

Connector strength 1.0. Both Prompt nodes use the expanded output.

Do not match seeds between the official V2Loader graph and this one. The noise path is different. Compare seeds only inside the same graph.
