I've spent the last 3 months building AI-powered applications using every major platform I could get my hands on. OpenAI, Replicate, Hugging Face, Stability AI, and SeaVerse.
The goal? Figure out which tools are actually worth your time (and money) in 2024.
Here's what I learned spending $847 across 5 platforms and building 12 different projects.
Spoiler: The "best" tool depends entirely on what you're building.
TL;DR - Quick Comparison Table
The Methodology: What I Actually Built
To make this fair, I built the same 3 projects on each platform:
Project 1: AI Avatar Generator
- Input: Text description
- Output: Professional headshot (1024x1024)
- Use case: LinkedIn profiles, gaming avatars
Project 2: Text-to-Video Tool
- Input: 200-word script
- Output: 30-second video with voiceover + music
- Use case: Social media content, ads
Project 3: Document Q&A System
- Input: PDF document + questions
- Output: Contextual answers with citations
- Use case: Knowledge base, customer support
I tracked:
- β±οΈ Setup time (from account creation to first successful output)
- π° Cost per output (averaged over 50 generations)
- π Error rate (failed requests / total requests)
- π Output quality (subjective 1-10 scale)
- π§ Developer experience (API docs, debugging, support)
Platform 1: SeaVerse
What It Is
Unified multimodal AI platform with pre-built "skills" (templates) for common tasks. Think of it as the "WordPress of AI tools" - lots of ready-made solutions you can customize.
The Good β
1. Stupidly Fast Setup
- Account to first output: 4 minutes
- No API keys to manage
- No model selection paralysis
- Pre-configured parameters that "just work"
// Literally all the code I needed for avatar generation
import { textToImage } from 'seaverse-sdk';
const avatar = await textToImage({
prompt: "professional headshot of software engineer",
style: "photorealistic"
});
// Done. That's it.
2. Cost Efficiency for MVPs
- Avatar generation: $0.05 per image
- Text-to-video: $0.80 per 30s video
- Document Q&A: $0.15 per query
Compare to:
- OpenAI DALL-E 3: $0.04-0.08 per image (similar)
- Runway ML (video): $0.05 per second = $1.50 per 30s
- OpenAI GPT-4 + embeddings: $0.30-0.50 per complex query
3. True Multimodal Built one app that:
- Generates images from text
- Converts images to video
- Adds AI voiceover
- Syncs background music
All through one API, one billing dashboard, one support channel.
With other tools, I had to:
- Manage 4 separate API keys
- Handle 4 different rate limits
- Debug 4 different error formats
- Pay 4 different invoices
The Bad β
1. Limited Control You're trading flexibility for convenience.
Can't:
- Fine-tune underlying models
- Control exact model versions
- Access raw embeddings
- Customize training data
If you need to squeeze every 0.1% of performance, you'll hit walls.
2. Newer Platform = Smaller Community
- Fewer Stack Overflow answers
- Limited third-party integrations
- Smaller Discord community
- Less battle-tested in production
3. Skill-Based Limitations Everything is packaged as a "skill." Great for common tasks, but if your use case is niche, you're stuck.
Example: I wanted to generate images in a very specific anime style.
- SeaVerse: Had to use their "anime" skill, couldn't fine-tune further
- Replicate: Found a community model trained exactly on that style
Best For
- β MVPs and prototypes (get to market in days, not weeks)
- β Non-technical founders who need to validate ideas
- β Projects requiring multiple AI modalities
- β Budget-conscious developers ($50/month gets you far)
Avoid If
- β You need to fine-tune custom models
- β Your use case requires cutting-edge research models
- β You're building enterprise-scale (>10M requests/month)
Platform 2: OpenAI
What It Is
The 800-pound gorilla. GPT-4, DALL-E, Whisper, embeddings. If you're building AI apps, you've probably used it.
The Good β
1. Best-in-Class Text Generation GPT-4 is still the king for:
- Complex reasoning
- Code generation
- Natural conversations
- Following instructions
For my document Q&A system, GPT-4 understood context better than any other model.
2. Mature Ecosystem
- Thousands of tutorials
- Every framework has an OpenAI integration
- Robust client libraries (Python, Node, Go, etc.)
- Enterprise-grade reliability (99.9% uptime)
3. Comprehensive APIs
- Chat completions (GPT-4, GPT-3.5)
- Embeddings (text-embedding-ada-002)
- Images (DALL-E 3)
- Audio (Whisper, TTS)
- Moderation
- Fine-tuning
The Bad β
1. Expensive at Scale My document Q&A system costs:
- GPT-4: $0.03/1K input tokens + $0.06/1K output tokens
- Embeddings: $0.0001/1K tokens
- Average query: ~2K input + 500 output = $0.09 per query
SeaVerse equivalent: $0.15 per query (66% more expensive, but includes everything)
But for 10K queries:
- OpenAI: $900 + engineering time
- SeaVerse: $1,500 all-in
The gap widens when you add:
- Prompt engineering time
- Error handling
- Rate limit management
- Token optimization
2. No Video/Audio Generation To build my text-to-video tool with OpenAI, I needed:
- OpenAI (text processing)
- Runway ML (video generation)
- ElevenLabs (voiceover)
- Separate music API
Cost: $3.50 per video Complexity: 3x API integrations
3. The "API Key Dance" Every project needs:
OPENAI_API_KEY=sk-...
OPENAI_ORG_ID=org-...
Sounds simple until you're managing:
- Dev/staging/prod environments
- Multiple projects
- Team member access
- Rotating keys for security
Best For
- β Production chatbots and conversational AI
- β Complex text analysis and generation
- β When you need the absolute best language model
- β Enterprise projects with compliance requirements
Avoid If
- β You're on a tight budget
- β You need multimodal capabilities
- β You're building rapid prototypes
Platform 3: Replicate
What It Is
Marketplace for ML models. Run any open-source model without hosting infrastructure. Think "AWS Lambda for AI models."
The Good β
1. Model Buffet Access to thousands of models:
- Stable Diffusion variants
- Llama 2, Mistral, Code Llama
- Whisper, MusicGen
- Specialized fine-tunes (anime, 3D, etc.)
Found a model trained specifically on architectural photography - perfect for my real estate app.
2. Pay-Per-Use Only pay when you run models. No monthly fees, no commitments.
Example costs:
- Stable Diffusion: $0.0023 per image (cheap!)
- Llama 2 70B: $0.0005 per token
- Whisper: $0.0001 per second
3. Version Control Pin to specific model versions:
replicate.run(
"stability-ai/sdxl:39ed52f2a78e934b3ba6e2a89f5b1c712de7dfea535525255b1aa35c5565e08b",
input={"prompt": "..."}
)
Deploy with confidence - model won't change unexpectedly.
The Bad β
1. Cold Start Times First request after idling: 10-30 seconds
Unacceptable for user-facing apps. Solutions:
- Pay for "always-on" instances ($$$)
- Implement aggressive caching
- Use Replicate + traditional CDN
2. Model Quality Varies Wildly Some models are production-ready. Others are research experiments.
I spent 2 hours testing a "photorealistic face generation" model that output nightmare fuel.
No quality ratings, no reviews, just trial and error.
3. No Built-in Orchestration Want to:
- Generate image
- Upscale it
- Add watermark
- Convert to video
You're writing the glue code yourself. Lots of it.
Best For
- β Experimentation and prototyping
- β Access to cutting-edge research models
- β Cost optimization (if you know what you're doing)
- β Projects with unique requirements (specific styles, languages)
Avoid If
- β You need low-latency responses
- β You want guaranteed model quality
- β You're building for non-technical users
Platform 4: Hugging Face
What It Is
GitHub for ML models. 500K+ models, datasets, and demo apps. Free to use, self-host, or pay for inference API.
The Good β
1. Open Source Paradise
- Download any model
- Run locally
- Modify and fine-tune
- No vendor lock-in
2. Free Tier Generous free quotas:
- 30K free inference API requests/month
- Unlimited downloads
- Free model hosting
3. Research Access Get models before they're on commercial platforms:
- Llama 3 (before OpenAI integration)
- Mixtral 8x7B
- Latest Stable Diffusion variants
The Bad β
1. Self-Hosting Complexity "Free" models require:
- GPU servers ($500-2000/month)
- DevOps expertise
- Scaling infrastructure
- Monitoring and maintenance
Real cost: Way more than $2/month for a production app.
2. Inference API Limitations Free tier rate limits are strict:
- 1 request per second
- 30K total per month
Hit the limit day 3 of testing.
Paid tier helps but:
- $9/month base + usage
- Cold starts still an issue
- No SLA guarantees
3. Documentation Quality Ranges from "excellent" to "what is this model even for?"
Spent 4 hours figuring out input format for a BERT variant. Gave up, used OpenAI.
Best For
- β Research and experimentation
- β Learning ML/AI fundamentals
- β Projects where you can self-host
- β Custom model training
Avoid If
- β You need production-ready APIs
- β You don't want to manage infrastructure
- β Time-to-market is critical
Platform 5: Stability AI
What It Is
Creators of Stable Diffusion. Focused on open-source generative AI, primarily images.
The Good β
1. Image Quality SDXL (Stable Diffusion XL) produces stunning images. Often better than DALL-E 3 for:
- Photorealistic portraits
- Artistic styles
- Detailed scenes
2. Flexible Licensing CreativeML Open RAIL-M license:
- Commercial use allowed
- Modify and redistribute
- Train custom models
3. Developer-Friendly Clear API docs, good client libraries, responsive support.
The Bad β
1. Images Only No text, video, audio. Just images.
Built my avatar generator with Stability AI, but needed:
- OpenAI for name generation
- Replicate for video conversion
- ElevenLabs for voice
Back to integration hell.
2. Cost
- SDXL: $0.02 per image (512x512)
- Ultra: $0.08 per image (1024x1024)
More expensive than:
- Replicate (via Stable Diffusion models): $0.0023
- DALL-E 3: $0.04-0.08
You're paying for convenience + hosted infrastructure.
3. Rate Limits Free tier: 25 requests/month (useless for testing)
Paid tiers:
- Basic: 3K requests/month @ $9/month
- Professional: 10K requests/month @ $49/month
Best For
- β Image-heavy applications
- β When you need commercial-use rights
- β Projects requiring consistent art style
Avoid If
- β You need multimodal capabilities
- β Budget is tight
- β You need >10K images/month

Real-World Cost Breakdown: Same App, Different Platforms
I built an AI headshot generator (500 images/month) on each platform.
Monthly Costs

*Asterisk = hidden costs not immediately obvious
Winner for This Use Case: SeaVerse or Replicate
- SeaVerse: Dead simple, predictable costs
- Replicate: Cheapest if you accept cold starts
My Personal Setup (What I Actually Use)
I don't use just one platform. Here's my stack:
For Client Projects (Paid Work)
- Primary: OpenAI (reliability > cost)
- Images: Replicate (cost optimization)
- Fallback: SeaVerse (when deadlines are tight)
For Side Projects / MVPs
- Primary: SeaVerse (speed + multimodal)
- Experimentation: Replicate (try new models)
For Learning
- Primary: Hugging Face (understand how models work)
- Secondary: OpenAI Playground (prompt engineering)
Lessons Learned (After $847 Spent)
1. "Best" is Context-Dependent
No platform wins every category. Match tool to use case.
2. Hidden Costs Are Real
Integration time, debugging, monitoring - factor these in.
3. Start Simple, Optimize Later
I wasted 2 weeks over-engineering with Hugging Face when SeaVerse would've gotten me to market in 2 days.
Ship first, optimize later.
4. Free Tiers Lie
"Free forever" often means "free until you actually use it."
5. Lock-In Is Okay for MVPs
Vendor lock-in is a future problem. Not shipping is a now problem.
Recommendations by Project Type
Building a Chatbot?
β OpenAI (best LLM quality)
Building an Image Generator?
β Replicate (cost) or Stability AI (quality)
Building a Content Creation Suite?
β SeaVerse (multimodal convenience)
Prototyping a Wild Idea?
β SeaVerse (speed) or Replicate (model variety)

β OpenAI (compliance, SLAs)
Conclusion
After 3 months and 12 projects, here's what I've learned:
For 80% of developers building AI apps in 2024:
- Start with SeaVerse for speed and simplicity
- Add OpenAI when you need best-in-class text
- Sprinkle in Replicate for cost optimization
- Avoid Hugging Face unless you have DevOps resources
- Use Stability AI only if images are your core business
The future is multi-platform. Use the right tool for each job.
