Understanding Tokenization

This tool functions as a universal tokenizer for OpenAI, Anthropic, and Google models. We use official Tiktoken libraries and model-specific tokenizers for 99% accuracy in token counting. Use this tokenizer to verify your prompt token counts before making API calls.

What is BPE (Byte-Pair Encoding)?

BPE is the tokenization algorithm used by GPT models. It breaks text into subword units by iteratively merging the most frequent character pairs. For example, "tokenization" might become ["token", "ization"]. This allows models to handle rare words efficiently while keeping vocabulary size manageable.

What is a Context Window?

The context window is the maximum number of tokens an LLM can process in a single request (input + output combined). GPT-4o offers 128K tokens, Claude 3.5 provides 200K tokens, and Gemini 1.5 Pro supports up to 2M tokens. Exceeding this limit will cause truncation or errors.

What is Cached Input Pricing?

Cached input pricing offers significant discounts (up to 90% off) when you reuse the same prompt prefix across multiple API calls. This is ideal for system prompts, few-shot examples, or document analysis where the context remains constant while only the query changes.

Input vs Output Token Costs

Output tokens are typically 2-4x more expensive than input tokens because they require the model to perform sequential generation. To optimize costs, design prompts that get concise responses, use output length limits, and choose the right model for each task.

Word-to-Token Conversion Guide

Token counts vary significantly based on content type and language. Use this reference to estimate token usage before running your text through the calculator.

Content TypeExampleRatio1000 Words ≈Notes
English TextHello world~1.3 tokens/word~1,300-1,500Standard prose averages 1.3 tokens per word
Code (Python/JS)def func():~2-3 tokens/word~2,000-3,000Symbols, operators, and syntax increase token count
Chinese/Japanese你好世界~2+ tokens/char~2,000+CJK characters often split into multiple tokens
Technical WritingAPI endpoint~1.5 tokens/word~1,500-1,800Technical terms and abbreviations vary
JSON/XML Data{"key":"value"}~3-4 tokens/word~3,000-4,000Structural characters add significant overhead

How Does AI Token Counting Work?

AI models like GPT-4o, Claude, and Gemini don't read text the way humans do. Instead, they use a tokenizer to break text into tokens — small chunks that can be whole words, word pieces, or even individual characters. The word “tokenization” becomes three tokens: “token”, “ization” — while common words like “the” are single tokens.

This matters because API pricing is based on token count, not word count. Our token calculator uses the same tiktoken library that OpenAI uses internally, running entirely in your browser via WebAssembly — so your text is never sent to any server.

Use the Token Visualizer above to see exactly how your text is split into tokens. Each colored chip represents one token — tap or hover over any chip to see its token ID. Compare token counts across different models to find the most cost-effective option for your use case.

❓ Common Questions

🔍
What is a token in AI and large language models?
A token is the basic unit of text that AI models like GPT-4o, Claude, and Gemini process. Tokens can be whole words, parts of words, or individual characters. In English, 1 token is roughly 4 characters or about 0.75 words. The word 'tokenization' becomes 3 tokens: 'token', 'ization'. API pricing is charged per token, not per word or character.
Did this answer your question?
What are the newest AI models available in 2026?
The newest models in 2026 include: GPT-4.1, GPT-4.1 Mini, and GPT-4.1 Nano from OpenAI (with 1M token context windows); Claude Opus 4.7 and Claude Haiku 4.5 from Anthropic; Gemini 2.5 Pro and Gemini 2.5 Flash from Google; Llama 4 Scout and Llama 4 Maverick from Meta; and DeepSeek V3-0324. Our calculator supports all of these models.
Did this answer your question?
How does this token calculator work?
This calculator uses the same tiktoken library that OpenAI uses internally, running entirely in your browser via WebAssembly. When you type or paste text, it tokenizes instantly with zero API calls — your text never leaves your device. The token count, word count, character count, and estimated cost are calculated in real time.
Did this answer your question?
Why do different AI models produce different token counts?
Each model uses a different tokenizer with a different vocabulary size. GPT-4o uses o200k_base (200K vocab), GPT-3.5 uses cl100k_base (100K vocab), Claude uses Anthropic's custom BPE, and Gemini uses SentencePiece. A larger vocabulary means common words are single tokens, making text more compact. The same sentence can produce different token counts on each model, directly affecting API cost.
Did this answer your question?
How much does it cost to use GPT-4o, Claude, or Gemini?
As of April 2026: GPT-4.1 costs $2.00/1M input tokens and $8.00/1M output tokens. Claude Sonnet 4.6 costs $3/$15 per 1M tokens. Gemini 2.5 Pro costs $1.25/$10 per 1M tokens. For budget options: GPT-4.1 Nano ($0.10/$0.40), Gemini 2.5 Flash-Lite ($0.10/$0.40), and Mistral Small ($0.10/$0.30) are the most affordable. Use our Monthly Cost Projector to estimate your monthly bill.
Did this answer your question?
What is prompt caching and how does it reduce costs?
Prompt caching allows AI providers to reuse computations from identical input prefixes (like system prompts). OpenAI offers 50% discount on cached tokens; Anthropic offers up to 90% discount. If you send the same 1,000-token system prompt with every request, caching can reduce that portion of your costs by half or more. It's the single most effective cost reduction for production applications.
Did this answer your question?
How can I reduce my LLM API costs?
Top strategies: 1) Enable prompt caching for repeated system prompts. 2) Use smaller models (GPT-4o Mini, Gemini 2.5 Flash) for simple tasks. 3) Set explicit max_tokens to limit output length. 4) Shorten system prompts — they're sent with every request. 5) Use the Batch API (50% discount on OpenAI). 6) Truncate conversation history instead of sending full context. Use our token calculator to test token counts before and after optimization.
Did this answer your question?
What is a context window and how does it affect cost?
A context window is the maximum number of tokens a model can process in a single request (input + output combined). GPT-4o has 128K tokens, Claude supports 200K, Gemini 2.5 Pro supports 2M, and GPT-4.1 and Llama 4 support up to 1M. Larger contexts cost more (more input tokens) but allow processing longer documents. If your text exceeds the context window, you'll see an error and need to chunk your content.
Did this answer your question?
Is my text data safe when using this calculator?
Yes, completely. This token calculator runs entirely in your browser using WebAssembly. Your text is never sent to any server or API — all tokenization happens locally on your device. There is zero data collection, no cookies tracking your input, and no external API calls made with your text. You can verify this by checking your browser's Network tab in Developer Tools — you'll see no outbound requests when typing.
Did this answer your question?
How accurate is this compared to the official OpenAI tokenizer?
For OpenAI models (GPT-4o, GPT-4.1, GPT-3.5), this calculator uses the exact same tiktoken library that OpenAI's API uses, so the token count is 100% accurate. For Claude, Gemini, DeepSeek, and Llama, we use the closest available approximation — results may vary by 3-8% depending on text content and language. For production cost estimation, always verify with a small test call to the actual API.
