API Pricing Comparison
| Vendor | Model | Input/1K tokens | Output/1K tokens |

| OpenAI | GPT-4o-mini | $0.15 | $0.60 |
| Anthropic | Claude 3.5 Sonnet | $3.00 | $15.00 |

Subscription Plans
For predictable costs, consider subscriptions:
- ChatGPT Plus: $20/month for personal use
- ChatGPT Team: $25/user/month
- Claude Pro: $20/month
- Google AI Premium: $20/month
- Ollama Pro: Flat monthly, good for API heavy use
Model Strengths
Price isn't everything—each model has strengths:
- GPT-4o: Best reasoning, best for complex tasks
- Claude 3.5: Long documents, coding, nuanced writing
- Gemini: Multimodal (images, video), Google integration
- GPT-4o-mini/Haiku: Fast, cheap for simple tasks
Japanese Market Considerations
- Data residency: Some vendors allow Japan-based data processing
- Language support: All major LLMs handle Japanese well now
- Billing: Most require international credit cards
- Support: English-only for most (Google has Japanese support)
Multi-Vendor Strategy
Smart businesses use multiple vendors:
- Default to cheapest: Use Gemini Flash or Haiku for routine tasks
- Escalate to capable: GPT-4o or Claude Sonnet when needed
- Specialized models: Different models for different tasks
- Fallback: If one API fails, route to another
Real Monthly Cost Example
For a business handling 10,000 conversations/month (~500 tokens each):
- GPT-4o: ~$6,250/month
- Claude Sonnet: ~$4,500/month
- Mixed strategy: ~$1,500/month (80% Haiku, 20% GPT-4o)
