よくある質問
How accurate are the token estimates?
The character-based estimate is within 10 to 15% for English text. Different models tokenize slightly differently, so for a precise budget, use the exact input token field or run a small sample through the real API.
Are these prices current?
Prices are public list prices at the time of the last update. Providers change pricing periodically; check the provider's pricing page before committing large volumes.
What is prompt caching?
Anthropic, OpenAI and DeepSeek offer a discount (roughly 90%) on input tokens that are repeated across calls, such as a long system prompt. If most of your prompt is a stable prefix, the cache hit rate is high and cost drops sharply.
Is my prompt uploaded anywhere?
No. All calculation runs in your browser. Your prompt text is not sent to any server.
