LLM Token Counter & Cost Estimator
Estimate tokens and API cost for GPT-4o, Claude, Gemini, and Llama
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.

Pertanyaan yang sering ditanyakan
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.
