Episode Overview

In this episode of My Weird Prompts, Corn and Herman Poppleberry dive into the rapidly shifting landscape of generative AI as we approach 2026. They explore whether the legendary Stable Diffusion can hold its ground against powerful newcomers like the Flux series and discuss the growing chasm between local hardware capabilities and cloud-based APIs. From architectural rendering to the "blurry cat" phase of local video generation, the duo debates the merits of community-driven ecosystems versus raw model power.

The world of generative artificial intelligence moves at a "light speed" pace that can leave even the most seasoned tech enthusiasts feeling winded. In a recent episode of My Weird Prompts, hosts Corn (a high-energy sloth) and Herman Poppleberry (a sturdy donkey) sat down to dissect the state of open-source AI as we head toward 2026. The central question of their debate: Is the "old guard" of local AI, specifically Stable Diffusion, being pushed aside by a new generation of high-fidelity models?

The Rise of Flux and the Quality Gap

For years, Stable Diffusion was the undisputed champion for users running AI on their own hardware. However, Herman points out that the release of the Flux.1 series by Black Forest Labs marked a massive turning point in the industry. Unlike older models that often struggled with "AI hallucinations"—such as the infamous seven-fingered hand—newer models like Flux offer superior prompt adherence and anatomical detail.

Herman argues that for professionals, such as architects or designers, the reliability of these new models is non-negotiable. While Stable Diffusion XL still boasts a massive ecosystem of custom LoRAs and checkpoints on community hubs like Civitai, the "base intelligence" of newer models allows for complex tasks like accurate text rendering and realistic spatial physics right out of the box.

The Local vs. Cloud Dilemma

One of the most pressing topics discussed was the divergence between local accessibility and cloud-based power. Corn highlighted a growing concern: is AI truly "democratized" if you need a $5,000 graphics card to run the best models?

Herman explained that we are seeing a split in the market. On one side, massive models are being accessed via APIs on platforms like Fal AI or Replicate. On the other, the open-source community is working tirelessly on "quantization"—the art of shrinking these massive models so they can fit into standard consumer V-RAM (8GB to 16GB).

Despite the convenience of the cloud, Corn remains a staunch advocate for local AI, citing privacy as the ultimate feature. For designers working on sensitive projects, the ability to keep prompts and outputs on a local hard drive, free from corporate terms of service or censorship, remains a powerful draw.

Fragmentation: A Toolbox or a Nightmare?

The current AI landscape is becoming increasingly fragmented, with various players like AuraFlow, CogVideo, and Stable Diffusion 3 vying for dominance. While Herman worries that this creates a "nightmare" for users who must learn new prompting styles and manage different environments every week, Corn views it as a sign of industry maturity.

Corn suggests that we are moving away from a "one size fits all" approach. In the near future, a user might use one specific model for architectural visualization because it understands straight lines, and a completely different model for character art. This "toolbox" approach allows for specialized excellence rather than mediocre versatility.

The New Frontier: Local Video

The conversation eventually turned to the next great hurdle: video generation. While the duo agrees we are currently in the "blurry cat" phase of local video—reminiscent of the early days of blurry AI images—the potential is staggering. Models like CogVideo are beginning to nip at the heels of major cloud players. Herman predicts that by 2027, users may be generating full movie trailers on their desktops, though the debate remains whether these will be powered by transformer-based, diffusion-based, or hybrid architectures.

Conclusion: Ownership in a Shifting World

The episode concluded with a reminder of why the local AI movement exists in the first place. Beyond the "tuxedo dog" pictures (much to the chagrin of their caller, Jim from Ohio), local AI represents ownership. As models become more complex and the hardware requirements grow, the community's commitment to keeping these tools in the hands of the individuals ensures that creativity remains uncensored and truly personal. Whether through Stable Diffusion’s legacy or Flux’s raw power, the "digital sandbox" is only getting bigger.

Episode #198: The Future of Local AI: Stable Diffusion vs. The New Guard

Corn
Welcome to My Weird Prompts! I am Corn, and I am feeling particularly energized today, even if I am a sloth and usually prefer the slow lane. We are diving into a topic that has been moving at light speed lately. Our producer, Daniel Rosehill, sent us a prompt that really gets to the heart of how we create things in this digital age. We are looking at the state of open source generative artificial intelligence as we move toward the year twenty twenty-six.
Herman
And I am Herman Poppleberry. It is a pleasure to be here, though I must say, the speed of this industry is enough to make even a sturdy donkey like myself feel a bit winded. The prompt today is asking a critical question: where does local AI stand? For years, Stable Diffusion was the undisputed king of the hill if you wanted to run powerful models on your own hardware. But now we have the Flux series from Black Forest Labs, and platforms like Replicate and Fal AI are churning out new models for image and video every single day.
Corn
It is wild, Herman. I remember when being able to generate a blurry cat on your home computer was a miracle. Now, architects are using these tools for professional rendering. But the big question is whether the old guard, specifically Stable Diffusion, is actually holding its ground or if it is becoming a digital relic.
Herman
Well, I think we have to be careful with the word relic. Stable Diffusion isn't exactly a spinning jenny from the industrial revolution. But you are right that the landscape has shifted. The release of Flux point one was a massive turning point. It brought a level of prompt adherence and anatomical detail that frankly made the older Stable Diffusion models look a bit amateurish.
Corn
See, I don't know if I agree that they look amateurish. If you go on any of the big community hubs, people are still doing incredible things with Stable Diffusion XL. There is this massive ecosystem of LoRAs and custom checkpoints that you just can't find for the newer models yet. Isn't there something to be said for the depth of a community versus just raw power?
Herman
There is, but raw power wins in professional workflows eventually. If an architect needs a render that actually follows their specific instructions about lighting and materials, they can't spend four hours fighting with a model that thinks a human hand should have seven fingers. Flux and its successors have moved the needle on reliability.
Corn
Okay, but let's take a step back for a second. For someone who isn't a power user, what are we actually talking about when we say open source in twenty twenty-six? Because some of these models are huge. You need a massive graphics card to run them locally. Is it really local AI if you need a five thousand dollar setup to host it?
Herman
That is a fair point. We are seeing a divergence. On one hand, you have the massive, high fidelity models like Flux Pro or the latest iterations from Black Forest Labs that are often accessed via API on platforms like Fal AI. On the other hand, we have the distilled versions. These are smaller, faster models that can run on a standard consumer laptop. The democratization is still happening, it just looks different than it did two years ago.
Corn
I still think the local aspect is being undervalued by the big labs. People want privacy. If I am a designer working on a secret project, I don't want my prompts going to a server in the cloud, even if that server is incredibly fast. That is why Stable Diffusion stayed relevant for so long. It was the ultimate sandbox.
Herman
I agree on the privacy aspect, but let's be realistic. The complexity of these models is scaling faster than consumer hardware. We are reaching a point where the gap between what you can do on your own machine and what you can do with a cloud API is becoming a chasm, not just a crack.
Corn
But isn't that exactly what the open source community is good at? Shrinking things? I mean, look at what happened with Large Language Models. We went from needing a server farm to running decent models on a phone in eighteen months.
Herman
True, but image and video generation are computationally more expensive by orders of magnitude. Especially when we move into image-to-video. Have you tried running a high-end video model locally lately? Your computer would double as a space heater for the entire neighborhood.
Corn
Hey, in the winter, that is a feature, not a bug! But seriously, I want to talk about these new players. Flux is the big name right now, but we are also seeing things like the AuraFlow models and various iterations of Stable Diffusion three. It feels like the market is fragmented. Is fragmentation good for us, or is it just making everything more confusing?
Herman
It is a bit of both. Fragmentation creates competition, which drives innovation. But for the end user, it is a nightmare. You have to learn a new prompting style for every model. You have to manage different environments. It is not like the early days where everyone was just using one version of Automatic eleven-eleven.
Corn
I actually think the fragmentation is a sign of maturity. We are moving away from a one size fits all approach. You might use one model for architectural visualization because it understands straight lines and perspective, and another model for character art because it handles skin textures better. It is like having a toolbox instead of just a single hammer.
Herman
Narrowing it down to a specific toolbox is fine, but the tools are changing every week. How is a professional supposed to build a stable workflow on shifting sand?
Corn
That is a great question, and I want to dig into that more, but first, we need to take a quick break for our sponsors.

Larry: Are you tired of your dreams being stuck in your head? Do you wish you could project your subconscious thoughts directly onto a physical medium without all that pesky talent or effort? Introducing the Dream-O-Graph five thousand! This revolutionary headband uses patented neural-static technology to capture your nighttime visions and print them directly onto any flat surface. Want to see that giant purple squirrel you dreamt about? Just strap on the Dream-O-Graph, take a nap, and wake up to a beautiful, slightly damp charcoal sketch on your living room wall. Side effects may include vivid hallucinations of Victorian-era street performers, a metallic taste in your mouth, and a sudden, inexplicable knowledge of how to speak ancient Babylonian. The Dream-O-Graph five thousand. It is not just a printer, it is a portal to your own confusion. Larry: BUY NOW!
Herman
...Alright, thanks Larry. I am not sure I want my dreams printed in damp charcoal, but to each their own. Back to the topic at hand. Corn, you were talking about the professional workflow.
Corn
Right! So, if I am an architect in twenty twenty-six, and I have been using Stable Diffusion for years, why would I switch? If I have my custom LoRAs for specific building materials and I know exactly how to use ControlNet to keep my walls straight, is Flux really going to offer me enough to justify relearning everything?
Herman
The short answer is yes, because of the base intelligence of the model. Stable Diffusion, even the XL version, often requires a lot of hand-holding. You need ControlNet just to make it do the basics. The newer generation of models, like Flux, have a much deeper understanding of spatial relationships and physics right out of the box. You spend less time correcting the AI and more time iterating on your design.
Corn
I don't know, Herman. I think you are underestimating the power of the legacy. There are thousands of free models on sites like Civitai that are built on top of Stable Diffusion. You can't just recreate that overnight. It is like saying everyone should switch from Windows to a brand new operating system just because the new one is ten percent faster. People stay for the software and the community.
Herman
But it isn't ten percent faster, Corn. It is a fundamental shift in quality. When you look at the text rendering in these new models, it is night and day. If an architect wants to include signage in a render, Stable Diffusion gives you alphabet soup. Flux actually writes the words. That kind of thing matters when you are presenting to a client.
Corn
Okay, the text thing is a huge win, I will give you that. But what about the hardware? If we are talking about local AI, we have to talk about the V-RAM. These new models are heavy. Are we moving toward a future where local AI is only for the elite with thirty-nine-ninety or fifty-nine-ninety cards?
Herman
That is the risk. But we are also seeing clever engineering. Quantization is the magic word here. We are taking these massive models and squeezing them down so they fit into sixteen or even eight gigabytes of V-RAM. It is a constant arms race between the model size and the compression techniques.
Corn
It feels like a bit of a treadmill. You buy a new card to run the new model, then a bigger model comes out that needs a bigger card. At what point do we just admit that the cloud is easier?
Herman
Never! Well, I shouldn't say never, but the local movement is fueled by a very specific philosophy. It is about ownership. If you have the weights on your hard drive, nobody can take them away. They can't change the terms of service. They can't censor your creativity based on a corporate whim.
Corn
I love that philosophy, but I worry it is becoming a niche. Most people just want the pretty picture. They don't care about the weights. They go to Fal AI or Replicate because it is one click and it works.
Herman
And that is exactly why the open source labs are trying to make their models more accessible. They know they are competing with the convenience of Midjourney and DALL-E. That is why we are seeing so many different versions of these models—Dev, Schnell, Pro. They are trying to cover every use case from the casual enthusiast to the high-end pro.
Corn
Let's talk about video for a second, because that seems to be the new frontier. We are seeing things like CogVideo and the new Luma models. Is local video generation even a reality for most people yet?
Herman
It is on the horizon, but it is very early days. Generating a single high-quality image is one thing. Generating twenty-four frames per second that are temporally consistent? That is a whole different beast. Right now, most of that is happening in the cloud. But the open source community is nipping at the heels of the big players.
Corn
I saw a demo the other day of a local video model that could do five seconds of a character walking. It was a bit shaky, but it was impressive. It reminded me of the early days of image generation.
Herman
Exactly. We are in the "blurry cat" phase of video. By twenty twenty-seven, we will probably be generating full movie trailers on our desktops. But the question of which architecture wins is still wide open. Will it be a transformer-based model? A diffusion-based model? A hybrid?
Corn
I bet on the hybrids. Usually, the middle ground is where the stability is. But speaking of stability, I think we have someone who wants to weigh in on our discussion. We have Jim on the line from Ohio. Hey Jim, what is on your mind today?

Jim: Yeah, this is Jim from Ohio. I have been listening to you two yapping about these fancy computer pictures for twenty minutes now and I have had just about enough. You are making it sound like this is some kind of revolution. It is just a more complicated way to make a fake photo. My neighbor Gary bought one of those high-end computers you were talking about, and all he does is make pictures of his dog wearing a tuxedo. What a waste of electricity! The power grid in my town is already shaky enough because of the heat wave.
Corn
Well, Jim, I think the tuxedo dog is just the beginning! It is about the creative potential for everyone.

Jim: Creative potential? Give me a break. In my day, if you wanted a picture of a dog in a tuxedo, you put a tuxedo on a dog and you took a photo! It didn't take ten gigabytes of whatever you called it. And don't get me started on the video stuff. I saw a video of a politician that looked real but wasn't, and it nearly gave me a heart attack. We can't trust anything anymore. It is like when the local grocery store started selling those "organic" apples that taste like cardboard. Total scam.
Herman
Jim, I hear your concerns about trust and deepfakes. Those are very real issues. But we are also talking about tools for architects and designers to build better buildings and more efficient products. Don't you think there is value in that?

Jim: Better buildings? They don't build anything to last anymore anyway! My porch is falling apart and I can't find a contractor who knows a hammer from a hacksaw. You think an AI is going to fix my porch? No, it is just going to make a pretty picture of a porch while the real one rots. Plus, my cat Whiskers is terrified of the fan on Gary's computer. Sounds like a jet engine taking off every time he tries to "render" something. It is a nuisance.
Corn
We appreciate the perspective, Jim. It is a good reminder that technology has real-world impacts, from the power grid to the noise in the neighborhood.

Jim: You bet it does. And someone needs to tell that Larry fellow that his dream machine sounds like a lawsuit waiting to happen. I am hanging up now, I have to go check on my tomatoes. They are looking a bit peaked.
Corn
Thanks for calling in, Jim! Always good to hear from you.
Herman
He isn't entirely wrong about the power consumption, you know. These models are incredibly hungry. If we are moving toward a future where everyone is running these locally, we are going to need a lot more green energy.
Corn
Or just more efficient models! That is what I keep saying. The trend shouldn't just be "bigger is better." It should be "smarter is better."
Herman
I agree, but currently, the path to "smarter" has been through "bigger." We haven't quite figured out how to get that high-level reasoning and visual understanding without billions of parameters.
Corn
Let's get back to the prompt's specific question about the pivot. Is there a general pivot toward different classes of models? Because Stable Diffusion was a U-Net architecture, right? And now we are seeing more Diffusion Transformers, or DiTs. Is that the "pivot" Daniel was asking about?
Herman
Yes, that is exactly the technical pivot. The U-Net architecture was great for a long time, but it has scaling limits. Transformers, which were originally designed for text, have turned out to be incredibly good at processing visual data too. Flux is a DiT. Stable Diffusion three is a DiT. This architecture allows the model to understand the relationship between different parts of an image much better.
Corn
So it's not just that the models are newer, it's that the underlying engine is totally different?
Herman
Exactly. It is like moving from a piston engine to a jet engine. They both get you where you are going, but the jet engine can go much faster and higher if you give it enough fuel.
Corn
That makes a lot of sense. But if I am a casual user who just wants to make some cool art for my Dungeons and Dragons campaign, do I really need to care about DiTs versus U-Nets?
Herman
You don't need to care about the math, but you will notice the results. You will notice that you don't have to type "five fingers, highly detailed, masterpiece" in your prompt anymore. You can just say "a hand holding a sword" and it will actually work. That is the practical takeaway.
Corn
I actually want to push back on that a little bit. I think there is a charm to the "struggle" with the older models. There is a specific aesthetic that came out of the limitations of Stable Diffusion one point five. Sometimes these new models are almost too perfect. They look like stock photos.
Herman
Oh, here we go. The "digital vinyl" argument. You think the flaws make it art?
Corn
In a way, yeah! If everything is perfectly rendered and anatomically correct, where is the soul? Where is the weirdness? That is why I think people will stick with the older models for certain creative projects. It is about the "vibe," Herman.
Herman
I can't argue with a "vibe," Corn, but I can argue with efficiency. Most people using these tools for work don't want a "vibe," they want a finished product that doesn't need ten hours of post-processing in Photoshop.
Corn
Fair enough. So, let's talk practical takeaways. If someone is listening to this and they want to get into local AI today, where should they start?
Herman
If you have a decent computer with at least twelve gigabytes of V-RAM, I would say look at a quantized version of Flux point one Dev. It is currently the gold standard for open weights. If you have less than that, Stable Diffusion XL is still a very solid choice and has the best community support.
Corn
And what about the software? Is it still all command line stuff and complicated installs?
Herman
Not at all. Tools like Forge or ComfyUI have made it much more accessible. ComfyUI in particular is great because it uses a node-based system. It is a bit of a learning curve, but it gives you total control over the process.
Corn
I tried ComfyUI once. It looked like a plate of spaghetti with all those wires and boxes. I preferred the simpler interfaces. But I guess if you want to be a "pro," you have to learn the nodes.
Herman
It is worth it, I promise. It is like learning to use a professional camera instead of just a point-and-shoot.
Corn
I also think it's important to mention that you don't have to choose just one. You can have multiple models installed. You can use Flux for the base image and then use a Stable Diffusion LoRA to style it. The future is definitely hybrid.
Herman
That is a great point. The interoperability is getting better. We are seeing bridges being built between these different ecosystems.
Corn
So, to wrap up the core of the discussion, it sounds like we are saying that while Stable Diffusion isn't dead, the "pivot" to Transformer-based models like Flux is very real and very necessary for the next leap in quality.
Herman
Absolutely. We are heading into an era where the boundary between "open source" and "state of the art" is almost non-existent. The models you can run at home are becoming just as capable as the ones behind the billion-dollar paywalls.
Corn
That is an exciting thought. Imagine what people will be creating by twenty twenty-six. We might have entire indie films made by one person in their bedroom.
Herman
Or just a lot more dogs in tuxedos, if Jim's neighbor has anything to say about it.
Corn
Hey, don't knock the tuxedo dogs! They are a vital part of the internet ecosystem.
Herman
I suppose they are.
Corn
Well, this has been a fascinating deep dive. We covered everything from the technical shift to DiT architectures to the philosophical importance of hardware ownership.
Herman
And we managed to mostly agree, which is a rare treat.
Corn
Don't get used to it, Herman. I am sure I will find something to disagree with you about in the next episode.
Herman
I look forward to it.
Corn
Before we go, a quick reminder that you can find My Weird Prompts on Spotify and all your favorite podcast platforms. Big thanks to Daniel Rosehill for this prompt—it really gave us a lot to chew on.
Herman
Indeed. It is a brave new world of pixels and parameters out there. Stay curious, everyone.
Corn
And keep those prompts coming! We love seeing what kind of weirdness you want us to explore next.
Herman
Just maybe nothing that involves Babylonian charcoal sketches.
Corn
Speak for yourself, Herman. I have already ordered three Dream-O-Graphs.
Herman
Of course you have.
Corn
Goodbye everyone!
Herman
Until next time.
