Frequently asked questions
Which LLM providers are supported?
We support OpenAI (GPT-3.5, GPT-4, GPT-4o), Anthropic (Claude 3 Haiku, Sonnet, Opus), Google (Gemini 1.5 Pro, Flash), and Mistral models with up-to-date pricing.
How accurate are the token counts?
We use the same tokenization libraries (tiktoken for OpenAI, official tokenizers for others) that the providers themselves use, so counts are exact.
What do I get with the Pro plan?
Pro unlocks batch prompt analysis, CSV import, API access for CI/CD pipelines, cost history dashboard, and team sharing features.
