# Project-Cosmos-V2.1 (Resolution Transplant)

**Cosmos V2.1** marks a strategic pivot. We identified that **NoobAI XL** has superior anatomy and style compared to previous bases. However, NoobAI sometimes struggles with very high resolutions (1536px+).

## The Method: Surgical Attention Transplant
* **Base:** **NoobAI XL v1.0** (100% of Anatomy, ResNets, Style, and Text Encoders).
* **Donor:** **IllumiYume v3.5** (Only providing Spatial Awareness).
* **Technique:** We applied **SLERP (50%)** *only* to the **Attention Layers** (`attn`/`transformer`). These layers control how the model handles pixel coherence at scale.

## The Result
* **Anatomy:** Pure NoobAI (Perfect fingers, good proportions).
* **Style:** Pure NoobAI (Soft lighting, no burns).
* **Resolution:** Inherited IllumiYume's ability to render native **1536x1536** without duplicating heads or breaking bodies.

## Recommended Settings
* **Sampler:** Euler a / DPM++ 2M SDE
* **CFG:** 5.0 - 8.0
* **Resolution:** Tested up to 1536x1536 (Native).
