Frequently Asked Questions
Which AI models are supported?
We support all major models including OpenAI GPT-4o, GPT-4 Turbo, GPT-3.5, Anthropic Claude 3 Opus/Sonnet/Haiku, Google Gemini Pro, and Mistral. New models are added as they launch.
How does the cost simulation work?
You upload a sample dataset (CSV or JSON), define a prompt template with variable placeholders, and the simulator renders each row through your template, counts tokens using each model's tokenizer, and multiplies by current API pricing to give you accurate cost estimates.
Is my data stored or used for training?
No. Your sample data and prompt templates are processed in-session only and never stored on our servers or used for any training purposes. Your IP is yours.
