An AI token is the smallest unit of text that a large language model processes. In English, one token averages ~4 characters or three-quarters of a word — so "hamburger" tokenizes to 3 tokens ("ham", "bur", "ger") and "hi" is 1 token. AI APIs from Anthropic (Claude), OpenAI (GPT-4o), and Google (Gemini) bill by the token, charging separately for input (text you send) and output (text generated). This convention has held across every major provider since GPT-3 launched in 2020.

What is the difference between input and output tokens?

Input tokens are everything you send to the model — your prompt, system instructions, conversation history, and any retrieved context. Output tokens are what the model generates in response. As of May 2026, output tokens are 3–5× more expensive than input tokens across every major provider: Claude Sonnet 4 is $3/1M input vs $15/1M output (5×), GPT-4o is $2.50/1M input vs $10/1M output (4×), and Gemini 2.0 Flash is $0.10/1M input vs $0.40/1M output (4×). The reason: generating each output token requires a full forward pass through the model, while input tokens are processed in parallel during prefill.

How many tokens is 1,000 words?

1,000 words of English text is approximately 1,333 tokens, based on the standard ratio of ~1.33 tokens per English word (4 characters per token, ~5.3 characters per word including spaces). A 250-word page is ~333 tokens, a 2,500-word document is ~3,333 tokens, and an 80,000-word novel is ~106,667 tokens. Code, non-English languages, and structured data tokenize differently — Chinese and Japanese often run 1–2 tokens per character.

How many tokens is 1 page of text?

A standard single-spaced page of English text (250–300 words) contains ~330–400 tokens. A double-spaced manuscript page (~250 words) is also ~333 tokens. A densely packed US Letter page at 500 words is ~667 tokens. For reference, the entire works of Shakespeare (~835,000 words) come to roughly 1.1 million tokens — fitting comfortably inside a single Gemini 2.5 Pro request (1M context window).

Which AI model is the cheapest in 2026?

As of May 2026, Llama 3.1 8B is the cheapest hosted mainstream model at ~$0.05/1M input tokens, followed by Gemini 1.5 Flash at $0.075/1M, Gemini 2.0 Flash at $0.10/1M, Mistral Small at $0.10/1M, GPT-4o mini at $0.15/1M, and Claude Haiku 4 at $0.25/1M. For high-volume production workloads, Gemini 2.0 Flash usually wins on cost-per-quality because it pairs the $0.10/1M input price with a 1 million-token context window — far larger than the others at the same tier.

What does "per million tokens" mean?

AI APIs price by the million tokens (often written $/1M tokens or $/MTok). If a model lists "$3/1M input", a 1,000-token prompt costs $0.003 (1,000 ÷ 1,000,000 × $3). Most single API calls cost fractions of a cent — but at production scale (10M+ requests/month) the choice between $0.10/1M and $3/1M is the difference between a $30 bill and a $900 bill for the same workload.

How does the TokenRate calculator work?

Enter a budget (USD), a token count, or a character count into the calculator. TokenRate uses live pricing from the OpenRouter API — refreshed hourly via Next.js ISR — to compute the exact tokens-per-dollar or dollars-per-token for every tracked model in parallel. It uses the standard 4-characters-per-token approximation for English text; precise per-tokenizer counts require provider-specific libraries (tiktoken for OpenAI, the Anthropic SDK for Claude).

Is the pricing data real-time?

Live pricing is pulled from the OpenRouter API and refreshed every hour via Next.js Incremental Static Regeneration. OpenRouter aggregates real-time pricing from Anthropic, OpenAI, Google, Meta, DeepSeek, xAI, and Mistral. Reference pricing on individual model pages is reviewed on a rolling cadence (last full sweep: 2026-05-22). For mission-critical decisions, always confirm with the provider's own pricing page.

Can I reduce my AI API bill without changing model?

Yes. Three high-leverage moves: (1) Prompt caching cuts the cost of cached input tokens by ~90% on Anthropic and ~50% on OpenAI — ideal for long, static system prompts. (2) Batch APIs from Anthropic and OpenAI offer a 50% discount with a 24-hour turnaround for asynchronous workloads. (3) Output-length controls (setting max_tokens, requesting concise answers) directly reduce the expensive side of the bill. Combined, these can cut costs 5–10× without changing models.

What is an AI token calculator? An AI token calculator converts between dollars, token counts, and characters using live API pricing from large language model providers. It answers two questions developers ask before shipping with an LLM: "how much will this prompt cost?" and "how many tokens does my budget buy?"

Current AI API pricing (July 2026): Llama 3.1 8B costs $0.05/1M input tokens; Gemini 2.0 Flash costs $0.10/1M; GPT-4o mini costs $0.15/1M; Claude Haiku 4 costs $0.25/1M. Output tokens cost roughly 3–5× the input price across every major provider. A typical 1,000-token request on a balanced model like Claude Sonnet 4 ($3/1M input) costs $0.003 — under a third of a cent. Use the calculator above to convert any amount across 288+ tracked models.

What Are AI Tokens?

A token is the basic unit that AI language models use to process text. Rather than reading word by word, models break text into token fragments — roughly 4 characters each for English. The word "hamburger" is 3 tokens; "hi" is 1 token.

Every AI API — including Claude, GPT-4o, and Gemini — charges by the token. You pay for the text you send (input tokens) and the text the model generates (output tokens). Understanding tokens is the key to predicting and controlling your AI costs.

How AI Token Pricing Works

AI models are priced by the million tokens — written as $/1M tokens. The two numbers you always see are:

InputThe text you send — your prompt, system instructions, and conversation history.
OutputThe text the model generates. Usually 3–5× more expensive than input, because generating tokens requires more compute than reading them.

A typical 1,000-token request (about 750 words of prompt) with Claude Sonnet 4 costs $0.003 — less than a third of a cent. At scale, though, those fractions add up fast.
