Token Optimization Tips

  • • Token counts are estimates based on model tokenization patterns
  • • Actual counts may vary slightly (typically within ±5%)
  • • Use clear, concise language to reduce tokens
  • • Avoid repetitive phrases and unnecessary formatting
  • • Prices are per 1,000 tokens (updated 2024)

AI Token Counter & Cost Calculator - Optimize Your AI API Costs

Our free AI token counter is an essential tool for developers, businesses, and AI enthusiasts who need accurate token counting and cost estimation across 24+ AI models. Whether you're working with GPT token counter needs,Claude token counter calculations, or Gemini token counter estimates, this comprehensive tool helps you optimize your AI cost calculator usage and manage your API expenses effectively.

Why Use an AI Token Counter?

Understanding token usage is crucial when working with AI models. Every AI API charges based on tokens - small units of text that models process. Our token calculator provides accurate token counting for major AI models including OpenAI's GPT-4, GPT-3.5, GPT-4o, Anthropic's Claude 3 series, Google's Gemini models, Meta's Llama, Mistral AI, and Cohere models. This token estimator helps you:

  • Calculate API costs accurately before making API calls
  • Optimize prompts to reduce token usage and costs
  • Compare costs across different AI models and providers
  • Stay within context limits with real-time token tracking
  • Budget planning for AI projects and applications

GPT Token Counter - OpenAI Models Supported

Our GPT token counter supports all major OpenAI models with accurate tokenization:

  • GPT-4 Token Counter: Count tokens for GPT-4, GPT-4 Turbo, and GPT-4o with 128K context windows
  • GPT-4o Mini: Calculate tokens for the cost-effective GPT-4o variant
  • GPT-3.5 Token Counter: Estimate tokens for GPT-3.5 Turbo model
  • OpenAI Token Counter: Real-time token counting with accurate cost estimates

Each model has different pricing structures, and our AI cost calculator helps you understand the true cost of your prompts before sending them to the API.

Claude Token Counter - Anthropic Models

The Claude token counter supports all Claude 3 models with their massive 200K token context windows:

  • Claude 3.5 Sonnet: Latest Claude model with improved performance
  • Claude 3 Opus: Most capable model for complex reasoning tasks
  • Claude 3 Sonnet: Balanced performance and cost
  • Claude 3 Haiku: Fastest and most cost-effective Claude model

Claude models use efficient tokenization, and our token count tool accurately estimates tokens to help you plan your Claude API usage and costs.

Gemini Token Counter & Other AI Models

Our Gemini token counter supports Google's latest models including Gemini 1.5 Pro with an incredible 2 million token context window - the largest in the industry. The tool also supports:

  • Gemini 1.5 Flash: Fast model with 1M token context
  • Llama Token Counter: Meta's open-source Llama 3 and Llama 2 models
  • Mistral AI Models: Mistral Large, Medium, Small, and Mixtral
  • Cohere Models: Command R+ and Command R for enterprise use

AI Cost Calculator - Estimate API Expenses Accurately

Our AI pricing calculator provides real-time cost estimates based on:

  • Input token costs: Cost per 1,000 input tokens for each model
  • Output token costs: Cost per 1,000 output tokens (typically higher than input)
  • Expected response length: Adjustable slider to estimate total costs
  • 2024 accurate pricing: Updated with latest pricing from all providers

This API cost estimator helps developers and businesses budget for AI projects, compare costs between models, and optimize prompt engineering to reduce expenses.

Free Token Counter - 100% Privacy & No Limits

Our free token counter operates entirely in your browser, ensuring complete privacy. Your prompts are never sent to external servers - all tokenization and cost calculations happen locally. This makes it perfect for:

  • Confidential prompts: Analyze proprietary or sensitive content safely
  • Unlimited usage: No API keys, no registration, no rate limits
  • Instant results: Real-time token counting as you type
  • Multiple models: Compare token usage across 24+ AI models instantly

AI Prompt Optimizer - Reduce Token Usage

Use our AI prompt optimizer features to reduce token usage and API costs:

  • Real-time token tracking: See token count update as you edit your prompt
  • Context window warnings: Alerts when approaching model limits
  • Cost comparisons: Instantly see cost differences between models
  • Example prompts: Pre-built examples to test tokenization

Optimize your prompts to be concise and efficient, reducing both token count and API costs without sacrificing quality.

Start using our AI Token Counter today - the free, accurate, and privacy-focused tool trusted by thousands of developers and businesses worldwide. Calculate tokens, estimate costs, and optimize your AI API usage across 24+ models, all processed securely in your browser.
