AI API Pricing Guide

How Token-Based Pricing Works

Most LLM APIs charge per token processed, split into two categories: input tokens (the text you send — your prompt, context, and history) and outputtokens (the model's generated response). Output pricing is typically 2–4× higher than input, as generation requires more compute.

In English, 1,000 tokens correspond to roughly 750 words. A full A4 page of text contains between 600 and 900 tokens.

Real-World Monthly Cost Example

Consider a company using the GPT-4o API to process 100 emails per day, with an average prompt of 800 tokens and a 300-token response. That's 110,000 tokens/day × 30 days = 3.3 million tokens/month. At $2.50/M input tokens and $10/M output:

  • Input: 2.4M tokens × $2.50/M = $6.00/mo
  • Output: 0.9M tokens × $10/M = $9.00/mo
  • Total: $15.00/mo

The same volume with Claude Haiku (~$0.25/M input) would cost only ~$1.73/mo — a significant saving when maximum quality isn't critical.

Strategies to Reduce API Costs

1. Pick the right model for each task: simple text classification can use Gemini Flash or Claude Haiku; reserve GPT-4o or Claude Opus for tasks that truly need advanced reasoning.

2. Compress your prompts: avoid repeating unnecessary context. Well-implemented RAG systems send only the relevant passages, not the entire document.

3. Cache responses: if the same prompt is sent repeatedly (e.g., product categorization), store results and reuse them. Providers like Anthropic offer prompt caching at a discount.

4. Use open-source models via third-party APIs: Groq, Together AI, and Fireworks serve models like Llama and Qwen at $0.01–$0.20/M tokens — 10–100× cheaper than proprietary frontier models.

Frequently Asked Questions about API Costs

How much does the GPT-4o API cost per token?

The GPT-4o API costs $2.50 per million input tokens and $10.00 per million output tokens (2026 pricing). For a business sending 1 million tokens per day, the monthly cost would be approximately $75 for input alone. Output tokens are 4× more expensive, so optimizing prompt length has a significant impact on cost.

What is the cheapest AI API available?

Open source models like Qwen, Llama and Gemma can be accessed via third-party APIs (Groq, Together AI, Fireworks) for fractions of a cent per million tokens — as low as $0.01–$0.10/M tokens. Among proprietary APIs, Gemini Flash and Claude Haiku are the most affordable at $0.08–$0.25/M input tokens.

What are tokens and how do I estimate my project cost?

Tokens are text units that LLMs process — in English, 1 token ≈ 4 characters. A standard A4 page has ~600–800 tokens. To estimate cost: (input tokens + output tokens) × price/1M tokens. Example: 500-token prompt + 300-token response = 800 tokens × model price.

Should I use the API or subscribe to ChatGPT Plus/Claude Pro?

For moderate personal use, a subscription ($20/month) is usually more economical. For heavy usage or product integration, the API is more flexible and scalable. The breakeven point typically occurs when your API token consumption exceeds the equivalent value of the monthly subscription.

How have AI API prices changed over time?

Prices have dropped dramatically: GPT-4 cost $30/M tokens in 2023; equivalent models now cost $2–5/M. The trend is continuous decline as competition increases. We update this table weekly — always verify official pricing before committing your budget.
