FAQ
Which AI models are supported?
We support all major OpenAI models (GPT-4o, GPT-4, GPT-3.5), Anthropic Claude models (Claude 3.5 Sonnet, Haiku, Opus), and Google Gemini models (1.5 Pro, Flash).
How accurate are the token estimates?
We use the same tokenization libraries as the model providers (tiktoken for OpenAI, official tokenizers for Anthropic and Google), so estimates are highly accurate — typically within 1-2 tokens.
Can I cancel my subscription anytime?
Yes. Cancel anytime from your billing portal with no questions asked. You keep access until the end of your billing period.
