What is the cheapest AI for customer support automation?
Gemini Flash via API at $0.075/1M input tokens is the cheapest capable model for support automation. GPT-4o mini is nearly as cheap at $0.15/1M and slightly more reliable on structured output tasks.
Should support teams use dedicated platforms like Intercom AI?
Intercom AI and similar platforms add workflow value (ticket routing, knowledge base integration, analytics) but at significantly higher cost than direct API access. Worth it for teams who need the full workflow platform, not just AI generation.
How do I estimate AI cost for customer support?
Estimate: average prompt size (ticket + context) + average response size, multiplied by monthly ticket volume. Run this through the calculator with your preferred model. At GPT-4o mini rates, most support teams spend $10–50/month on AI generation alone.
