Token counts are estimates based on average characters-per-token (~4 for GPT-4o). Actual counts from the model's tokenizer may differ by 5–15%. Prices reflect published rates and may change - check the provider's pricing page for authoritative numbers.

Sık sorulan sorular

How accurate are the token counts?

They're estimates based on average characters-per-token (~4 for GPT, ~3.6 for Claude). Actual counts from the model's real tokenizer usually differ by 5–15%.

Where do the prices come from?

Published rates from OpenAI, Anthropic, Google, and hosted-Llama providers. Rates change - always verify with the provider before building financial projections.

Does it upload my prompt?

No. Counting and cost math run entirely in your browser.

Why does context-used % matter?

If a prompt approaches the model's context window, the model may truncate or refuse. The gauge helps you stay well under the limit.
