Pricing Models Explained
AI providers use various pricing structures for their models. Understanding these different approaches helps you choose the most cost-effective option for your specific needs.
Per-Token Pricing
How It Works
The most common pricing model:
- Charged based on number of tokens processed
- Separate rates for input and output tokens
- Output typically costs more than input
- Billed per 1,000 or 1 million tokens
Advantages
- Pay only for what you use
- Scales with actual usage
- No minimum commitments
- Transparent cost structure
Disadvantages
- Unpredictable monthly costs
- Can be expensive at high volumes
- Requires usage monitoring
- Complex cost forecasting
Examples
- OpenAI: $2/$8 per million tokens for o3
- Anthropic: $3/$15 per million tokens for Claude 4 Sonnet
- Google: $1.25/$10 per million tokens for Gemini 2.5 Pro
Subscription Models
How It Works
Fixed monthly fee for access:
- Set monthly payment
- Includes predefined usage limits
- May have overage charges
- Often includes premium features
Advantages
- Predictable monthly costs
- Often cheaper for high volume
- Simplified budgeting
- May include additional benefits
Disadvantages
- Pay even with low usage
- Potential for unused capacity
- Overage charges can be expensive
- Less flexibility
Examples
- ModelBooth: $10/month for all models
- GitHub Copilot: $10/month for code assistance
- Midjourney: $10/month for image generation
- ElevenLabs: $5/month for voice synthesis
Credit-Based Systems
How It Works
Purchase credits to spend on usage:
- Buy credits in advance
- Different operations cost different credits
- Credits may expire after a period
- Volume discounts on larger purchases
Advantages
- Prepaid cost control
- Volume discounts
- Flexible usage across services
- Simplified internal billing
Disadvantages
- Credits may expire
- Upfront payment required
- Complex credit conversion rates
- Potential for unused credits
Examples
- Adobe Firefly: Credit-based image generation
- RunwayML: Credits for video generation
- Various API platforms: Credit packages
Enterprise Pricing
How It Works
Custom pricing for large organizations:
- Negotiated contract terms
- Volume-based discounts
- Service level agreements (SLAs)
- Dedicated support and resources
Advantages
- Lower per-unit costs
- Customized terms
- Priority support
- Higher rate limits
Disadvantages
- Minimum spending commitments
- Contract lock-in periods
- Complex negotiation process
- Less flexibility
Examples
- OpenAI Enterprise: Custom pricing and features
- Azure OpenAI: Enterprise deployment options
- Anthropic Claude Enterprise: Custom contracts
Free Tiers and Trials
How It Works
Limited free access:
- Free monthly token allowance
- Trial credits for new users
- Rate-limited access
- Feature restrictions
Advantages
- No cost for limited usage
- Test before committing
- Suitable for development
- Good for learning
Disadvantages
- Strict usage limits
- Limited features
- Lower priority
- May not allow commercial use
Examples
- OpenAI: Free trial credits
- Google AI: Free tier with rate limits
- Hugging Face: Free inference API
Open Source Models
How It Works
Free to use, self-hosted:
- No direct model costs
- Self-hosting required
- Infrastructure costs apply
- Commercial use often allowed
Advantages
- No per-token fees
- Complete control
- Privacy and security
- Customization options
Disadvantages
- Infrastructure costs
- Technical expertise required
- Maintenance responsibility
- Often lower performance
Examples
- Meta Llama: Open source models
- Stability AI: Stable Diffusion
- Mistral AI: Open models
Hybrid Pricing Models
Tiered Usage
Combination of subscription and usage:
- Base subscription fee
- Included usage allowance
- Overage charges for excess usage
- Volume discounts at higher tiers
Feature-Based Pricing
Pay for specific capabilities:
- Base model access at lower cost
- Premium features at additional cost
- Add-on capabilities
- Custom feature packages
