How much does it cost to build an AI feature?

A basic AI feature (chatbot, summarizer) costs $10-$100/month in API fees on budget models. A production AI agent with RAG costs $50-$500/month. Premium models like GPT-5.5 or Claude Opus 4.8 can push costs to $500-$5,000/month for the same usage. Our planner above estimates your exact costs.

What is the cheapest way to add AI to my app?

Start with budget models: Gemini 2.5 Flash-Lite ($0.10/$0.40), DeepSeek V4 Flash ($0.14/$0.28), or GPT-4o mini ($0.15/$0.60). Use model routing to send simple tasks to cheap models and complex tasks to premium ones. Add caching for repeated queries. This can reduce costs by 50-80%.

How do I estimate AI API costs for my startup?

Estimate your daily requests, average input/output tokens per request, and multiply by 30 days. Then check pricing for your chosen model. A startup with 1,000 users making 5 requests/day with 500 input and 300 output tokens spends $9-$450/month depending on the model. Use our budget planner for detailed estimates.
