What is AI Run Rate?
AI Run Rate is a free AI agent cost calculator that helps developers and businesses model their AI agent costs before shipping. The tool allows users to compare GPT-4o, Claude, Gemini, DeepSeek and 50+ models to determine the most cost-effective option for their specific use case. Users can build a workflow by inputting their agent's parameters and get instant cost projections without surprises on their bill.
Key features include access to real pricing for over a thousand models fetched from LiteLLM, covering OpenAI, Anthropic, Google, Mistral and other providers. The calculator models actual agent behavior including tool calls per turn, reasoning steps, retry rates, follow-up conversation rates, and escalation to human operators. It includes a dashboard with 3-year projections, cost per query, cost per user per month, and visual bar charts. The tool also supports custom fields and custom formulas that can be created and modified at runtime.
The calculator covers often-forgotten costs beyond just LLM tokens, including infrastructure, personnel, security, operations, initial investment to build, and a contingency buffer. Prices get cached for a week and if offline, the tool falls back to defaults. Every assumption is explicit and visible in the UI, making results reproducible with dated pricing snapshots that users can verify, share, and save.
AI Run Rate is designed for AI developers, engineering teams, startup founders, product managers, and anyone building or working with AI agents who needs to understand true TCO (Total Cost of Ownership) before deployment. It's particularly useful for teams comparing different models for their agent, planning budgets for AI features, or presenting cost analysis to stakeholders.

Frequently asked questions about AI Run Rate
What is AI Run Rate?
AI Run Rate is a free AI agent cost calculator that helps you model your AI agent costs before you ship. It allows you to compare GPT-4o, Claude, Gemini, DeepSeek and 50+ models, build a workflow, and get instant cost projections without surprises on your bill.
Is AI Run Rate free to use?
Yes, AI Run Rate is completely free to use with no signup required. There are no payment walls or premium tiers - you can use all features including the 3-year projection dashboard and custom fields at no cost.
How many AI models does the calculator support?
The calculator supports 50+ popular models including GPT-4o, Claude, Gemini, and DeepSeek. It fetches real pricing for over 1000 models from LiteLLM covering OpenAI, Anthropic, Google, Mistral, and other providers.
How accurate are the cost projections?
The calculator uses real pricing data fetched from LiteLLM and caches prices for a week. It models your agent's actual behavior including tool calls per turn, reasoning steps, retry rates, and follow-up conversation rates. However, it includes a contingency buffer because estimates are always wrong.
What costs does the calculator include?
Beyond just LLM tokens, the calculator covers infrastructure, personnel, security, operations, the initial investment to build the agent, and a contingency buffer. It models the complete TCO (Total Cost of Ownership) that people often forget.
Can I customize the calculator for my specific use case?
Yes, the calculator lets you add custom fields with a name, value, and optionally wire them into existing formulas. You can also create calculated fields that reference other fields by name. Custom fields and formulas can be created and modified at runtime.
What happens if I'm offline?
If you're offline, the calculator falls back to default pricing values. The prices are normally cached for a week, so you can still use the tool even without an internet connection, though the defaults may not reflect the latest pricing.
Does AI Run Rate show model performance benchmarks?
No, AI Run Rate focuses specifically on cost modeling and does not include performance benchmarks, accuracy comparisons, or quality metrics. It helps you understand costs but you'll need to test models separately for performance evaluation.
How do I use the dashboard features?
The dashboard displays a 3-year projection, cost per query, cost per user per month, and bar charts. After entering your agent's parameters and selecting models, the dashboard automatically updates live with all metrics and visualizations.
Can I save and share my cost scenarios?
Yes, the tool provides dated pricing snapshots that you can verify, share, and save. Results are reproducible and you can share your assumptions with stakeholders. According to related tools, you can save one scenario free with repricing and email alerts.
