Frequently asked questions

Which AI models are supported?

We support all major OpenAI models (GPT-4o, GPT-4 Turbo, GPT-3.5), Anthropic Claude 3.5 Sonnet/Haiku/Opus, and Google Gemini 1.5 Pro/Flash. Pricing is updated automatically when providers change rates.

How accurate are the token counts?

We use tiktoken — the same tokenizer OpenAI uses internally — so counts are exact for OpenAI models. For Anthropic and Google we use their documented tokenization rules, giving you estimates within 1–2% of actual billing.

Can I cancel my subscription?

Yes, cancel anytime from your billing portal with one click. You keep access until the end of your billing period. No questions asked.
