For an AI influencer who needs the same face across hundreds of posts, Stable Diffusion and other open models give the most control: free weights you can run locally, character LoRAs, ControlNet poses and no subscription, at the cost of setup and a capable GPU. Midjourney is the faster start: no hardware, strong default styling, V8.2 as its default model since July 24, 2026, and an Edit model that keeps a character recognizable from up to four reference images. It costs $10 to $120 a month, allows only safe-for-work content, bans automation, and makes images public unless you use Stealth mode on Pro or Mega.
Checked on October 1, 2026 against Midjourney's documentation, Stability AI's licenses, policies, announcements and API pricing, and official model cards. This update replaces the January 2026 version, whose 1-to-10 ratings, consistency percentages, savings figures and creator case study could not be traced to any source.
The short answer
- Choose Stable Diffusion (or another open model) if you need the same face in every post, exact poses, private local files, batch automation, or commercial terms you control. Expect to learn ComfyUI or a similar tool and to need a GPU or a cloud service.
- Choose Midjourney if you want polished images today without hardware, your content is safe for work, and reference-based consistency is close enough for your character.
- Use both if you want Midjourney for exploring looks and an open model for producing the recurring character.
Neither tool is better at everything, and this page does not score image quality; it compares what each vendor documents. Try both on your own character before committing.
What each option is in October 2026
Midjourney
Midjourney is a hosted image and video service used on midjourney.com or in Discord. According to its Version page, V8.2 has been the default model since July 24, 2026, V8.1 (April 14, 2026) and V7 remain selectable, and Niji 7 is the anime model. It can also animate your images into short videos. Our Midjourney prompts guide covers V8.2 parameters in detail.
Stable Diffusion
Stable Diffusion is Stability AI's family of open-weight image models. The newest is Stable Diffusion 3.5: Large (8.1B parameters) and Large Turbo from October 22, 2024, and Medium (2.5B) from October 29, 2024. Stability's core models list shows no newer open image model as of October 2026. Older SDXL (July 2023) and SD 1.5 are still widely used because so many fine-tunes, LoRAs and ControlNets target them.
You run these models in a local app such as ComfyUI, or through Stability's API or a hosted service. In practice, the "Stable Diffusion route" in 2026 means the open-model workflow as a whole, and many creators now pair it with newer open models such as Z-Image, FLUX.2 [klein] or Qwen-Image; our best ComfyUI models guide compares them and their licenses.

Character consistency, the deciding factor
An AI influencer only works if followers recognize the same person in every post. The two tools get there differently.
Midjourney: references
On V8.1 and V8.2, the Edit model generates new images from up to four reference images and replaces both Omni Reference (V7) and Character Reference, whose --cref parameter now runs only on V6 and Niji 6. If features from two characters get mixed up, Midjourney suggests combining them into a single reference image. Its Omni Reference page warns that intricate details such as specific freckles or logos may not perfectly match the reference, and the same caution applies to any reference-based method. It is quick and needs no training, but you are relying on the model to reinterpret the face each time.
Stable Diffusion: trained adapters and control
With open weights you can train a character LoRA, a small adapter that learns your character from a curated set of images, and then add a pose ControlNet to place that character in exact poses and inpainting to fix details. The weights never change unless you change them, which matters when a hosted model updates. The trade-off is time: you build a dataset, train, and compare checkpoints, and no recipe guarantees the same face in every image.
What each costs
Midjourney plans
| Plan | Monthly | Billed annually | Fast GPU time | Relax mode |
|---|---|---|---|---|
| Basic | $10 | $96 ($8 a month) | 3.3 hours | None |
| Standard | $30 | $288 ($24 a month) | 15 hours | Unlimited images |
| Pro | $60 | $576 ($48 a month) | 30 hours | Unlimited images and SD video |
| Mega | $120 | $1,152 ($96 a month) | 60 hours | Unlimited images and SD video |
Extra Fast time costs $4 an hour, and Midjourney says one image prompt usually takes about a minute of GPU time. There is no free trial on the website or in Discord; a limited trial exists only in the niji·journey mobile app. Stealth mode, which keeps images off the public website, starts at Pro.
Stable Diffusion costs
The software and weights are free. What you pay depends on where the model runs:
- Your own GPU: no per-image fee after the hardware and electricity. Stability said SDXL 1.0 should work on consumer GPUs with 8 GB of VRAM, and that SD 3.5 Medium needs 9.9 GB, excluding text encoders.
- A rented GPU: pay by the hour. Our cloud GPU comparison covers the options, including Comfy Cloud, the official hosted ComfyUI, whose plans start at $20 a month.
- Stability's API: pay per image, at $0.01 per credit, with 25 free credits to start.
| Stability API model | Credits per image | Price per image |
|---|---|---|
| SD 3.5 Large | 6.5 | $0.065 |
| SD 3.5 Large Turbo | 4 | $0.04 |
| SD 3.5 Medium | 3.5 | $0.035 |
| Stable Image Core | 3 | $0.03 |
| Stable Image Ultra | 8 | $0.08 |
Prices from Stability's pricing page on October 1, 2026; failed generations are not charged. At those rates, 1,000 SD 3.5 Large images cost $65. The API serves Stability's own models rather than your custom LoRAs, so LoRA-based production usually runs in ComfyUI on a local or rented GPU.
Licenses, content rules and disclosure
Midjourney
- Ownership: the Terms of Service say you own the images you create to the fullest extent the law allows, with exceptions. A company, or an employee of a company, with more than $1,000,000 a year in revenue must be on Pro or Mega to own its images.
- Content: the Community Guidelines allow safe-for-work content only and promise especially strict action against sexualized images of real people.
- Honesty: the guidelines say not to intentionally mislead recipients of generated images about their nature or source.
- Automation: Midjourney does not provide an API, apart from rare explicit exceptions, and its terms prohibit automated tools.
Stable Diffusion
- SD 3.5 (Stability AI Community License): free for research, non-commercial use and commercial use by individuals or organizations with less than $1 million in annual revenue. Commercial users must register with Stability; above the threshold, the license ends and you must request one from Stability. You own your outputs, and you may not use them to create or improve a foundational generative AI model.
- SDXL and SD 1.5 (CreativeML Open RAIL++-M and OpenRAIL-M): commercial use is allowed, the licensor "claims no rights in the Output", and use-based restrictions ban uses such as harming minors, defamation and harassment.
- Acceptable Use Policy: Stability's policy, which covers self-hosted models under its Community License, prohibits sexually explicit content (including non-consensual intimate imagery), impersonating others without consent, and misleading people about the nature of outputs, "such as pretending it was made by a human."
Both sets of rules point the same way for AI influencers: present the character as AI-generated, never use a real person's likeness without consent, and follow each platform's labeling rules. Our AI Instagram model guide covers Instagram's. These are summaries of the license text, not legal advice.
A workflow that uses both
- Explore the look in Midjourney. Try faces, styling and mood with V8.2,
--rawfor more photographic results, and style references or moodboards to settle an aesthetic. - Decide how strict consistency must be. If Edit model references hold the face across your shot list, you can stay in Midjourney.
- If not, rebuild the character on an open model. Generate a reference set on the base model you will train, curate it hard, and train a LoRA, following our LoRA guide.
- Produce in ComfyUI. Combine the LoRA with a pose ControlNet, fix hands and faces with inpainting, and upscale.
- Animate the best stills with an image-to-video tool; our Kling tutorial and AI video generator comparison cover the options.
- Disclose and publish under each platform's AI rules.
Our AI Influencers course covers this pipeline end to end, from character design and LoRA training in ComfyUI to video and publishing rules.

Stable Diffusion vs Midjourney FAQ
Is Stable Diffusion or Midjourney better for AI influencers?
It depends on what you need most. Stable Diffusion and other open models give more control over a recurring face through character LoRAs, ControlNet poses and local, private generation, but they take setup and a capable GPU or a paid cloud service. Midjourney is quicker to start, needs no hardware and keeps a character recognizable from up to four reference images with its Edit model, but it allows only safe-for-work content, bans automation and makes images public unless you use Stealth mode on Pro or Mega.
Can I use Stable Diffusion and Midjourney together?
Yes. A common split is to explore looks and moods in Midjourney, then produce the recurring character in an open model with a LoRA, where you control the face, pose and output files. Keep each tool's terms in mind for the images it produces.
How do I keep a character's face consistent in Midjourney?
On V8.1 and V8.2, use the Edit model with up to four reference images of the character. On V7 the equivalent is Omni Reference, and --cref (Character Reference) only works on V6 and Niji 6. Midjourney's Omni Reference docs warn that intricate details such as freckles or logos may not match exactly, so review every image.
How do I keep a character's face consistent with Stable Diffusion?
Train a character LoRA on the base model you will generate with, then combine it with a pose ControlNet and inpainting to fix details. A LoRA improves consistency but no recipe guarantees the same face in every image, so compare saved checkpoints on a fixed set of test prompts.
Do I need a powerful PC for Stable Diffusion?
Stability AI said SDXL should work on consumer GPUs with 8 GB of VRAM, and that SD 3.5 Medium needs 9.9 GB of VRAM excluding text encoders. Without a suitable GPU you can rent one, use Comfy Cloud, or call Stability's API, where an SD 3.5 Medium image costs $0.035 and an SD 3.5 Large image $0.065.
Is Midjourney free?
No. Midjourney offers no free trial on its website or in Discord; a limited trial exists only in the niji·journey mobile app. Plans cost $10, $30, $60 or $120 a month, with 20% off for annual billing.
Can I sell images made with Stable Diffusion or Midjourney?
Generally yes, within each license. SD 3.5 is free for commercial use for individuals and organizations with less than $1 million in annual revenue, after registering with Stability AI; above that you need a separate license. SDXL and SD 1.5 use CreativeML RAIL licenses that allow commercial use within their use restrictions. Midjourney says you own your images to the fullest extent the law allows, with exceptions, and a company with more than $1 million in yearly revenue must be on Pro or Mega to own them.
Does Midjourney have an API?
No. Midjourney says that, with a few rare exceptions it explicitly grants, it does not provide an API, and its terms prohibit automated tools. If you need automated or batch generation, an open model in ComfyUI or Stability's API is the route.
