About Tiktokenizer
Tiktokenizer.org helps developers and AI users inspect text tokens and turn token assumptions into transparent API cost estimates.

What does Tiktokenizer do?
Tiktokenizer counts text with a compatible local encoding, displays token boundaries and IDs, models chat-message overhead separately, and compares dated text-token prices from official provider sources. The browser tool supports prompt review, context planning, and early budget decisions; provider usage remains the stronger record for a complete production request.
What does Tiktokenizer not claim?
Tiktokenizer is not a billing system and does not claim every provider count is exact. It does not reproduce private provider tokenizers, hidden request framing, media accounting, or final invoices. The result excludes provider-side details that are not present in the browser input, so API usage records remain the final source of truth.
Is Tiktokenizer affiliated with model providers?
No. Tiktokenizer.org is an independent token analysis and AI API cost estimation tool. It is not affiliated with OpenAI, Anthropic, Google, DeepSeek, TikTok, or the original Tiktokenizer open-source project. Provider and model names identify the inputs being estimated; they do not imply endorsement, official status, or a partnership.
How is Tiktokenizer funded?
Pricing records are research-based and link to first-party sources with a checked date. The site may later earn commissions from clearly labeled affiliate links, but no affiliate provider is active in the current configuration. A future commission will not convert a provider link into evidence or make a recommendation automatically rank first.
What did the current Tiktokenizer verification measure?
The current automated test measured 18 canonical routes, unique metadata, server-rendered answers, source links, calculator interactions, long-input Worker counting, redirects, missing-route responses, and 45 responsive screenshots. Its limitation is provider scope: the test did not submit prompts to live model APIs, compare invoices, verify analytics receipt, or validate an affiliate destination.
How does Tiktokenizer handle mutable model pricing?
17 active model records use one centralized pricing source with a provider URL and exact checked date. Long-context price tiers are encoded where the official source changes rates above a token threshold. Missing pricing remains unavailable instead of becoming zero, time-limited pricing shows its valid-through date, and DeepSeek is explicitly marked for review. Users should still reopen the linked official source before funding an account or publishing a purchase budget.
Why is a monitored Tiktokenizer contact still required?
A monitored publisher contact has not yet been supplied. That remains a release blocker and is not hidden behind a fabricated email address. Until it is configured, use the source links to verify pricing and do not rely on this site for time-sensitive support, privacy requests, corrections, or commercial-rights notices.
Which official source and methodology keep Tiktokenizer estimates within an evidence boundary?
Tiktokenizer counts submitted text locally, labels each model result Exact, Compatible, or Estimate, and separates the visible-text count from provider billing. OpenAI's token guide confirms that tokens can be words, word fragments, punctuation, or spaces. Provider usage records remain authoritative for complete requests because browser input does not contain every API wrapper, tool, media, cache, or output item. OpenAI official token guide.

| Evidence | Observed result or boundary |
|---|---|
| Site-owned measurement | Browser-local compatible text count, disclosed chat allowance, context planning, and dated cost scenario. |
| Provider-owned evidence | Official tokenizer or API token count, complete usage response, current price, and final invoice. |
Why is independence a Tiktokenizer product boundary?
Provider names identify the models being estimated. They do not imply endorsement, official status, or a partnership.
