cfg

1 - 3.5

Tips

Simple prompts describing what you want to see in natural language works well.

Chroma prompts work well due to similarity in training caption styles.

Negative prompts may not work at CFG one but can be important otherwise.

Adjust CFG value depending on steps and sampler settings.

Use JoyCaption for image captioning and OneTrainer for training.

Version Highlights

Tries to fix the main issues people have reported having with v1 and v1.2

Chroma base model here.

This finetune aims to improve reliability in realistic/photo-based styles while preserving Chroma’s broad concept knowledge. The v1.3 flash version has the rank-256 lora (from here) baked in. bf16 and fp8 available --->. GGUFs on HuggingFace.

Prompting: Simple prompts describing what you want to see in natural language works well (example1, example2). Chroma prompts work well. Examples of captioning style used in training: woman sitting, waterfall, wolf, woman in dessert. Negative prompts don't work at CFG one, but above one negative prompts can be important.

Example settings (not necessarily optimal) using Comfy's default Chroma workflow:
Base: Steps:: ~30-40. CFG: ~3.5 (best settings depend on steps/CFG/sampler, etc.).
Flash (lora rank-128 or 256): Steps: 15-17. CFG 1. (Depends on lora rank, sampler, etc.)
Sampler: Examples use res_2m, dpmpp_sde, or exp_heun_2_x0_sde. Others are also good.
Scheduler: I like bong_tangent | beta & beta57 and others are also good

Training Details
The model was trained locally, using Chroma-HD as the base. Each epoch included images at 3–5 different resolutions, though only a subset of the dataset was used per epoch. Except for the extra resolutions, OneTrainer's default config for 24gb Chroma finetuning was used. The dataset consists almost exclusively of SFW-images of people and landscapes, so to retain Chroma-HD's original conceptual understanding, several layers were merged back at various ratios. All the juice, compositions, subjects, and concepts come from Chroma itself, my model just nudges it towards realism. Honestly, this version is a showcase of how good Chroma is. So get to work on Chroma finetuners - it has so much potential!

All images were captioned using JoyCaption: https://github.com/fpgaminer/joycaption

The model was trained using OneTrainer: https://github.com/Nerogar/OneTrainer
