AI Model Pricing Calculator
How much would the same workload cost on each AI model? Enter your monthly token volume below — input and output are billed at different rates, so they are entered separately.
Example: a support chatbot handling 1M conversations a month with short prompts might use ~50M input and ~10M output tokens. Prices are the providers' standard API rates in USD per 1M tokens, checked 2026-11-01. Prompt caching, batch discounts and committed-use discounts are not included.
| Model | Provider | Input cost | Output cost | Total / month |
|---|---|---|---|---|
| GPT-6 Luna | OpenAI | $5.00 | $5.00 | $10.00 |
| Claude Haiku 5.5 | Anthropic | $5.00 | $5.00 | $10.00 |
| Gemini 3.8 Flash | $37.50 | $37.50 | $75.00 | |
| GPT-6.1 Terra | OpenAI | $50.00 | $50.00 | $100.00 |
| Gemini Omni Flash | $75.00 | $90.00 | $165.00 | |
| GPT-6.1 Sol | OpenAI | $100.00 | $100.00 | $200.00 |
| Claude Sonnet 5.5 | Anthropic | $100.00 | $100.00 | $200.00 |
| Claude Opus 5.5 | Anthropic | $200.00 | $200.00 | $400.00 |
At 50M input / 10M output tokens per month, the cheapest option above costs $10.00 and the most expensive $400.00 — a 40x spread for identical token volume.
How to read these numbers
Providers bill input tokens (your prompts, context and documents) and output tokens (the model's replies, including reasoning tokens on reasoning models) at separate per-million-token rates. Output tokens are usually several times more expensive, so two workloads with the same total token count can have very different bills. That is why this calculator takes the two volumes separately instead of asking for one combined number.
