Learning Time
To proficiency
The gold standard for serious AI influencer creators. Completely free, infinitely customizable, and with LoRA training you achieve 95-98% facial consistency - the highest of any tool on this list.
Creators generating 100+ images monthly, those who value complete control, and anyone willing to invest time upfront for zero recurring costs. If you're building a serious AI influencer business, SD is non-negotiable.
The Beginner's Best Friend
Per Month
Basic/Standard plans
Consistency
70-80% with --cref
Learning Time
To first results
The fastest path from idea to image. No installation, no GPU, no learning curve - just type a prompt and get stunning results in 60 seconds. Perfect for validation and concept testing.
Beginners, concept artists, and rapid prototyping. Use MJ to test 20-30 character concepts in Week 1, then transition to SD for production once you find a winner. The $30-60 validation cost is worth it.
The Precision Character Designer
Per Month
Free tier available
Consistency
Gene-based mixing
Learning Time
Slider-based interface
Artbreeder uses a unique gene-mixing approach where you blend existing faces with sliders. Want 60% of Face A, 40% of Face B, with specific eye color and age adjustments? Artbreeder makes it trivial.
Character face design before transitioning to other tools. Use Artbreeder to dial in the perfect face (ethnicity, age, features), export it, then use that reference in SD or MJ for full-body generation.
The AI Headshot Library
Per Month
Based on downloads
Consistency
Random generation only
Learning Time
Instant usability
Different approach: Instead of generating custom characters, browse 100,000+ pre-generated AI faces and license the ones you like. Great for quick starts but poor for consistency.
One-off needs, mockups, and placeholder content. Not recommended for AI influencers due to zero character consistency. Better used for business headshots or design mockups.
The AI Video Influencer Platform
Per Month
+ custom avatar fees
Consistency
Perfect video cloning
Learning Time
Intuitive editor
Synthesia specializes in talking head AI avatars. Create a custom avatar (from your photos or AI-generated), then make it speak any script in 120+ languages. Perfect for educational or talking-head influencer content.
Educational influencers, course creators, and YouTube talking-head channels. If your AI influencer will primarily speak to camera (tutorials, reviews, vlogs), Synthesia is unmatched. Not suitable for Instagram fashion influencers.

98K Instagram followers | $12K/month revenue
"Midjourney let me test 40 different character concepts in 2 weeks - different ethnicities, styles, ages. Once I found a winner (Asian fashion model aesthetic), I moved to Stable Diffusion for consistency. Now I generate 300 images monthly for free. The hybrid approach was perfect."
45K subscribers | $8K/month AdSense + sponsors
"Synthesia was worth every penny. I write scripts, paste them in, and get a polished talking-head video in 20 minutes. Published 200+ videos in Year 1 - impossible for a human. The AI never gets tired, never has a bad hair day, and speaks 5 languages perfectly."
Assuming you generate 300 images per month for an AI influencer posting 10x/day across Instagram + TikTok:
| Tool | Upfront Cost | Monthly Cost | Year 1 Total | Cost/Image |
|---|---|---|---|---|
| Stable Diffusion | $600-800 | $3 | $636 | $0.18 |
| Midjourney | $0 | $60 | $720 | $0.20 |
| Artbreeder Pro | $0 | $18 | $216 | $0.06 |
| Leonardo.AI | $0 | $48 | $576 | $0.16 |
| Synthesia | $1,000 | $67 | $1,804 | $0.50* |
| Rosebud AI | $0 | $499 | $5,988 | $1.66 |
*Synthesia pricing is per video minute, not per image. Cost shown is estimated for video influencer use case.
While SD has the highest upfront cost ($600-800), it becomes the cheapest option by Month 2 and offers unlimited scaling. By Year 3, your cost-per-image drops to $0.006 while subscription tools remain at $0.06-$1.66.

Month 2+: Train LoRA on winning character, produce 300+ images/month free

Stable Diffusion is 100% free and open-source forever, but requires a GPU ($300-800 one-time). Artbreeder and Leonardo.AI both offer limited free tiers (10 credits/month and 150 images/month respectively) with no GPU requirement - perfect for testing before investing.
Stable Diffusion with LoRA training achieves 95-98% facial consistency - the highest available. Second place: Synthesia (9/10) for video avatars and Rosebud AI (10/10) for managed enterprise solutions. Midjourney's --cref feature reaches 70-80% consistency, which is decent but not ideal for daily posting influencers.
Yes, all tools listed allow commercial use with proper licensing. Stable Diffusion has zero restrictions (100% ownership). Midjourney requires paid plan ($30+/month) for commercial rights. Artbreeder, Leonardo.AI, Synthesia all include commercial license in paid tiers. Always verify current Terms of Service before monetizing.
Only for Stable Diffusion (requires RTX 3060+ GPU, 12GB+ VRAM). All other tools are cloud-based and work on any computer, phone, or tablet. Alternative: Use cloud GPU services like RunPod ($0.34/hour) or Google Colab (free tier available) to run Stable Diffusion without buying hardware.
Midjourney - hands down. 30-minute learning curve, Discord-based interface, instant stunning results. Just type "/imagine [your description]" and get professional-quality images. Artbreeder is second-best for beginners due to its intuitive slider interface. Stable Diffusion is powerful but has a steep 2-4 week learning curve.
Budget range: $0-$1,800 depending on approach. Free route: Artbreeder + Leonardo.AI free tiers ($0). Mid-tier: Midjourney validation ($30-60) → Stable Diffusion production ($600-800 GPU) = $630-860 total. Premium: Synthesia custom avatar ($1,000) + subscription ($804/year) = $1,804 Year 1.
Yes! Synthesia specializes in talking-head AI video avatars (custom avatar + text-to-speech in 120 languages). Runway ML offers Gen-2 video generation. D-ID and HeyGen also create AI video presenters. For image-based influencers (Instagram/TikTok photos), stick with Stable Diffusion or Midjourney.
Typical timeline: Month 1-2 (validation with free/cheap tools), Month 3 (invest in SD or premium tools), Month 4-6 (grow to 10-50K followers), Month 6+ (monetize via brand deals). Revenue potential: 25K followers = $1-3K/month, 100K followers = $5-15K/month, 500K+ followers = $20-50K/month from sponsorships alone. Tool investment ($630-1,800) typically pays for itself in first brand deal.
