Iris 3B | Forge Neo Extension

Generate with Iris 3B inside Forge Neo, using the checkpoint, preset and Generate button you already know: an image model that paints every pixel directly, with no VAE, plus 4x image restoration, depth maps and 4-step turbo images, even on 8 GB GPUs.

Requires an up-to-date Forge Neo (the neo branch). On an older version it stays disabled and says so in the console, and Forge Neo keeps working as usual.

Features 🚀

🖼️ Native Generation

• Runs inside txt2img: no separate tab, no extra environment

• No VAE to choose: Iris paints the picture directly, and the live preview shows the real image as it forms

• Uses the same text encoder as Krea 2, so if you have Krea 2 you already have it

• Loads the bf16 and the lighter INT8 checkpoints, tested on an 8 GB RTX 2070

⚡ Turbo LoRA

• A 1024x1024 image in 4 steps, about 4 seconds on an RTX 2070

• Its own Iris Turbo schedule in the Schedule type list

🔍 Restore x4

• A small or blurry picture restored and enlarged four times in a single pass, in img2img

• Large pictures are handled in pieces and blended, with no seams

🌊 Depth

• A greyscale depth map of any picture in img2img, near is bright, ready for depth ControlNets

🔌 LoRA

• Iris LoRAs with the usual <lora:name:weight> syntax, with the bf16 and INT8 checkpoints alike

🛡️ Safe by Design

• Changes no Forge Neo file: remove the extension and everything is as it was

• Checks your Forge Neo at startup and tells you what to change instead of making a wrong image

• Other models are not affected

Recommended Settings ⚙️

• Images: Iris DPM++ 2M, Iris schedule, 50 steps (100 for the best quality), CFG 3, empty negative prompt

• Turbo LoRA at weight 1: LCM, Iris Turbo, 4 steps, CFG 1

• Use about 1 megapixel with sides a multiple of 16, such as 1024x1024, 1152x896 or 1280x832
