FAQ
Which AI providers are supported?
We support OpenAI (GPT-4o, GPT-4, GPT-3.5), Anthropic (Claude 3.5, Claude 3), and Google Gemini. More providers are added regularly.
How is token cost calculated?
We pull live pricing from each provider's API and calculate exact input/output token costs per run, so you always see the true cost of each prompt variant.
Can I export my experiment results?
Yes. Every experiment can be exported as a CSV with all metrics — latency, token counts, costs, and model outputs — for further analysis in your own tools.
