Understanding AI Pricing
AI model pricing is based on tokens (pieces of text). Most providers charge separately for input tokens (what you send) and output tokens (what the AI generates).
- •1 token ≈ 4 characters or about 0.75 words in English
- •Output tokens cost more than input tokens (typically 2-5x)
- •Prices are per million tokens and vary by model capability
- •Cheaper models are great for simple tasks, while premium models excel at complex reasoning
Tips to Reduce AI Costs
Choose the Right Model
Use cheaper models for simple tasks and premium models only when needed
Optimize Your Prompts
Shorter, clearer prompts reduce token usage without sacrificing quality
Implement Caching
Cache common responses to avoid repeated API calls for the same queries
Set Token Limits
Use max_tokens parameter to prevent unexpectedly long (and expensive) responses
