Most people hit a wall with text-to-image tools like DALL-E or Midjourney. You type a prompt, get something close-ish, and then frustration sets in because you cannot edit it further. The closed-source approach gets you started fast but leaves you stuck. Open source – specifically Stable Diffusion and ComfyUI – changes that dynamic entirely. You get the model, you can inspect the training data, and most importantly you can build workflows that express exactly what you want.
ComfyUI turns image generation into a node-based workflow, much like DaVinci Resolve does for video editing. Instead of a single prompt-in, image-out pipeline, you chain together models, positive and negative prompts, sampling steps, and post-processing into a directed graph. This is where the real expressiveness begins. You can combine text prompts with image-to-image guidance, in-painting for targeted edits, out-painting to extend compositions, and ControlNet models like OpenPose for body positioning and depth maps for 3D structure. None of this is possible with just words in a text box.
Fine-tuning takes things further. With DreamBooth you can train the model on 20-30 images of a specific style, person, or object. LoRAs act as lightweight patches you can mix and match – combine a Roman statue style with moss textures and anime aesthetics in a single generation. Sites like CivitAI have built entire community ecosystems around sharing these fine-tuned models. IP Adapter offers a shortcut: provide a single reference image instead of doing a full fine-tuning run.
The video generation side is equally compelling. AnimateDiff lets you create short video sequences using image models, combining pose sequences with prompt traveling for multi-scene stories. Camera LoRAs give you zoom, pan, and crane movements – director-level control through prompts. Stable Zero adds 3D repositioning of subjects, and lighting control rounds out the toolbox. Add audio generation and you have a complete production pipeline.
What excites me most is the automation layer emerging on top. Vision models can judge aesthetic quality and pick the best generation from a batch. LLMs can generate optimized prompts. You can export ComfyUI workflows as Python code, wrap them as tools for LangChain, or deploy them as web apps for non-technical users. The community plugin ecosystem is thriving precisely because the tooling is open source. This is a pattern we have seen before: open ecosystems win by enabling others to build on top.
