π‘ Cost Optimization Strategies
Reduce your API costs by 30-70% with these proven techniques
Prompt Caching
Reuse system prompts and repeated content. OpenAI, Anthropic, and Google offer 50-90% discounts on cached tokens.
Batch API
For non-real-time tasks, use batch endpoints. Most providers offer 50% discount with 24h turnaround.
Optimize Input/Output Ratio
Code tasks have high output ratio - prioritize low output price. Chat tasks are balanced - look at total price.
Model Tiering Strategy
Use cheaper models (GPT-4o-mini, Gemini Flash) for simple tasks. Reserve premium models for complex reasoning.
Need the cheapest LLM API, not just a calculator?
Use the live workload guide to compare low-cost chat, code, reasoning, long-context, and free-tier options before you estimate monthly spend.
Need to understand the billing model first?
Read the AI pricing models guide to separate token, subscription, reserved-capacity, and enterprise costs before choosing calculator assumptions.
Need to count tokens from text first?
Use the AI token calculator to count characters and words, estimate tokens from a prompt, and apply a tracked model's input and output rates before projecting monthly spend.
OpenAI API pricing calculator
Planning GPT, o-series, embeddings, cached input, Batch API, or Responses API tool usage? Use the dedicated OpenAI calculator to separate token cost from cached context, delayed jobs, and billable tool calls.

Estimating Azure sentiment analysis cost?
Sentiment analysis is measured in Azure Language text records, not LLM tokens. Read the record formula, free-tier caveats, and lifecycle note before using a token calculator.
Calculating Anthropic Claude API costs?
Use the Claude-specific calculator to model Sonnet, Haiku, Opus, prompt caching, batch jobs, and output-heavy workloads.
Calculating official DeepSeek API costs?
Use the DeepSeek-specific calculator for V4 Flash and V4 Pro cache-hit input, cache-miss input, output tokens, and monthly request volume.

π Token Estimation Deep Dive
Understanding token consumption helps you estimate costs accurately and optimize prompts
Tokens by Language
| Language | Chars/Token | Example |
|---|---|---|
| English | ~4 chars | "Hello world" = 2 tokens |
| δΈζ | ~1.5 chars | "δ½ ε₯½δΈη" = 3 tokens |
| ζ₯ζ¬θͺ | ~1.5 chars | "γγγ«γ‘γ―" = 3 tokens |
| Code | ~3 chars | More symbols = more tokens |
Typical Token Ranges by Task
| Task Type | Input | Output |
|---|---|---|
| Simple Chat | 100-500 | 200-800 |
| Summarization | 2k-10k | 200-500 |
| Code Generation | 500-2k | 1k-5k |
| Document Analysis | 5k-50k | 500-2k |
Precise Token Counting with tiktoken
For accurate estimates, use OpenAI's tiktoken library (works for most models):
pip install tiktoken
import tiktoken
enc = tiktoken.encoding_for_model("gpt-4o")
len(enc.encode("Your text here"))Hidden Costs to Watch Out For
Your actual bill may be higher than calculated. Factor in these often-overlooked costs:
Failed Retries
Rate limits, timeouts, and errors still consume tokens. Budget 10-20% extra for retries.
Development & Testing
Debugging, prompt iteration, and testing can consume 2-5x your production usage initially.
Context Window Bloat
Long conversations accumulate context. A 10-turn chat may use 10x the tokens of turn 1.
