My take on an XL Pony, intended to veer more towards realism by default but without losing any knowledge of specific characters or concepts from the base model. Does not contain any third-party data from non-Pony XL checkpoints or Loras. Constructed solely from a series of bucketed 1280px Florence-2 Large / WD-VIT-3 captioned Loras that I trained myself directly on Base Pony, and iteratively merged at various strengths. All-in-all, version 1.0 has ~6500 images worth of new data.

Recommended basic positive prompt:

score_9, score_8_up, score_7_up, optional_rating_whatever, optional_source_whatever, your prompt here

Recommended basic negative prompt:

score_3_up, score_4_up, score_5_up, sketch, greyscale, monochrome, (simple background:1.3)

Recommended sampler / CFG / steps settings:

Euler Ancestral with Normal scheduling at 7.0 CFG and 25 - 35 steps is always a good starting spot. DPM++ SDE GPU and DPM++ 3M SDE GPU can also give nice results (at lower CFG, around 4.0 - 5.0, Exponential scheduling for 3M, Normal scheduling for uh, normal) if you're really aiming for realism.

If you use an up-to-date installation of ComfyUI, the "Clip Set Last Layer" node is NOT necessary with XL models like this one. Just do not use it.
