## UPDATE! - added a prompt rebuilder node to satisfy the models need for a VERY strict json structure. this is not normal json, its what i like to call "LingBot" json prompting as its alot more in depth. try it out!



Repackaged weights of [robbyant/lingbot-video-dense-1.3b](https://huggingface.co/robbyant/lingbot-video-dense-1.3b)
for use with the **[ComfyUI_Rebels_LingBot](https://github.com/RealRebelAI/ComfyUI_Rebels_LingBot)**
node pack. No weight modification — the original diffusers shards are merged/renamed into
single files for ComfyUI's model folders. All configs ship inside the node pack.

Runs T2V and TI2V on an **RTX 3070 8GB / 16GB RAM**: the Qwen3-VL encoder is loaded on
CPU, used, and freed before the 1.3B DiT (2.79GB bf16, fully VRAM-resident) starts.

## Files

| File | Put in | Size |
|---|---|---|
| `LingBot_1.3b_DiT.safetensors` | `ComfyUI/models/diffusion_models/` | ~2.8 GB |
| `LingBot_text-encoder.safetensors` | `ComfyUI/models/text_encoders/` | ~8 GB |
| `LingBot_vae.safetensors` | `ComfyUI/models/vae/` | ~0.5 GB |

The text encoder is the repo's Qwen3-VL, shards merged into one file (bit-identical
tensors). `lm_head.weight` is intentionally absent — it is tied to `embed_tokens`; the
node pack re-ties it at load.

## Recommended settings

- **832×480**, up to **81 frames**, 40 steps, shift 3.0
- guidance **3.0** (t2v) / **~3.0** (TI2V — higher burns color on image runs)
- export at **24 fps**
- VAE tiling **off** unless you must (temporal color/exposure drift on long clips)

~14 s/it on a 3070 at the settings above (sequential CFG); ≈10 minutes per 81-frame clip.

## Notes & limitations

- The trained window is 81 frames; longer generations collapse.
- Square/other aspect ratios are out-of-distribution (letterboxing artifacts) — stay at 832×480.
- 1.3B-class video: modest motion complexity; rendered text (signs/labels) is not legible.
- TI2V requires the image to be fed to **both** the encode node (vision conditioning) and
  the sampler (first-frame latent) in the node pack's workflow.
