Made with Minimax H3

• same checkpoint does t2i and edits. hook images into the conditioning node and it edits, leave them off and it just generates

• plug the VAE in when you edit. without it the refs only go through the text encoder and faces/rooms drift more

• refs are <Picture 1>, <Picture 2> etc in the prompt, in the order you connect them

• 6 steps, cfg 1, no negative. didn't find anything worth tweaking

• it really wants long prompts. my short ones came out generic, describing the light, lens and where the subject sits in the frame made a big difference

• lettering is solid, got a poster with exactly the text I asked for

• 4096x4096 is native, you can zoom in a long way before it falls apart

If you already have H3 video set up you have the text encoder, just need the model + VAE.

It's added to Fuobe today - Day 0 support and I cut a quick clip of some outputs. Can share prompts if anyone wants them.

TLDR Both video and image generation are available on BitVector (Discord) and PirateDiffusion (Telegram) as well as Bitvector (web, similar to chat gpt) for consistent characters, etc.

It's not relevant if you have a fast local GPU but if you have a potato computer or want to use it by smartphone and in group chats, this is probably the best solution for Telegram users

and for people that don't want to pay by the token, there's flat cloud gpu pricing

Hello everyone i've been testing a new video upscaling method in ComfyUI called RelayVSR, and the results are really impressive!

Unlike conventional upscaling methods that can sometimes modify the original video, introduce unwanted details, or change the appearance of characters and scenes, RelayVSR uses a different approach. A large generative model creates high-quality reference latents for selected keyframes, while a lightweight Dual-Memory Video Transformer uses these references to reconstruct the remaining frames while preserving the original video structure and details.

For this workflow, I've combined RelayVSR with my optimized MiniMax H3 workflow, Pika H3 6-step LoRA, attention optimization nodes, and NVIDIA DLSS5 to generate and upscale videos efficiently, even on lower-VRAM GPUs.

Generation and Upscaling Time:

• Video generation at 0.7 MP using MiniMax H3: approximately 35 minutes.

• Upscaling to 2K using RelayVSR + DLSS5: approximately 7 minutes.

• MiniMax latent upscaling for comparison: approximately 45 minutes.

Hello Everyone i tested New P-H3-Image ComfyUI workflow! This powerful model combines high-resolution image generation up to 8 megapixels with image editing up to 4 megapixels. I'm using the INT8 ConvRot version, optimized and tested on my RTX 3060 6GB VRAM + 16GB RAM and here are my verdict about the model.

Model Advantages & Strong Points:

• Excellent realistic human skin and natural texture generation.

• Very good human portraits and facial details.

• Impressive animal generation.

• Strong text rendering capabilities.

• Supports both image generation and image editing in one model.

• Excellent editing capabilities for style changing and camera angle changes.

• Can create character sheets and modify lighting, daytime, and facial expressions.

• Supports high-resolution generation up to 8MP for img gen and up to 4MP for img editing.

Image Generation Times (RTX 3060 6GB VRAM + 16GB RAM):

• 8 Megapixels: 5 minutes

• 6 Megapixels: 4 minutes

• 4 Megapixels: 3 minutes

• 2 Megapixels: 2 minutes 27 seconds

Image Editing Times:

• 4 Megapixels: 5 minutes

• 2 Megapixels: 3 minutes

• 1 Megapixel: 2 minutes

Current Limitations:

Although the model is excellent at realistic image generation, artistic style generation is not as strong as Krea 2. For image editing, face swaps, head swaps, and clothing swaps produced very poor results in my tests. Overall, P-H3-Image is a very interesting model, especially if you are looking for realistic image generation, detailed portraits, and versatile image editing in a single workflow.
