FAQ
Which AI models are supported?
We support OpenAI GPT-3.5 and GPT-4 family, Anthropic Claude 2 and 3 family, Google Gemini 1.0 and 1.5, and Mistral models. New models are added as they launch.
How accurate are the token estimates?
We use the same tokenizers as each provider (tiktoken for OpenAI, claude tokenizer for Anthropic) so estimates match production billing within 1–2%.
Can I cancel my subscription anytime?
Yes. Cancel from your billing portal at any time. You keep access until the end of your billing period with no questions asked.
