What is Mydentify AI Model Cost Calculator?

The Mydentify AI Model Cost Calculator is a free web tool for estimating and comparing what different AI models would cost through their APIs. You enter a monthly workload, meaning requests per month, input tokens per request, output tokens per request and the percentage of input that is cached, then pick the models to compare. The calculator applies each model's public per-token rates to the same workload and shows the estimated monthly bill, the cost per request and each model's context limit side by side. Prices refresh hourly from the OpenRouter public model catalog, and no account or API key is required. The page states its limits plainly: estimates leave out provider discounts, taxes, free tiers, retries, tool charges and negotiated pricing, and a cheaper model is not necessarily a better fit for quality, latency or reliability. It sits in a small set of AI model economics tools alongside an LLM usage cost analyzer that runs in your browser.

Use cases

  • Compare monthly API costs across AI models
  • Plan an AI API budget
  • Estimate cost of a chatbot workload
  • Check savings from prompt caching
  • Compare context limits between models

Who it's for

  • Developers
  • Product managers
  • Startup founders
  • Finance teams

Why use Mydentify AI Model Cost Calculator

  • Every model is priced against the same workload, so the differences are easy to read.
  • You can see how output length and repeated context change a bill, not just the headline per-token rate.
  • It needs no sign-up or API key, so you can run a quick estimate in a minute.
  • Hourly price refreshes keep estimates close to the public rates you would see on the catalog.

Mydentify AI Model Cost Calculator features

  • Inputs for requests per month, input tokens, output tokens and cached input percent
  • Side-by-side monthly and per-request cost estimates
  • Context limit shown next to each model
  • Prompt caching applied when a model publishes a cache-read price
  • Model prices refreshed hourly from the OpenRouter public catalog
  • No account and no API keys required
  • Plain-text guide describing the method and limits

How to get started with Mydentify AI Model Cost Calculator

  1. Enter your monthly request volume and the average input and output tokens per request.
  2. Set the share of input tokens that are cached, if your prompts repeat the same context.
  3. Choose the current text models you want to compare from the refreshed catalog.
  4. Review the estimated monthly and per-request cost for each model alongside its context limit.

Mydentify AI Model Cost Calculator limitations

  • Estimates exclude provider discounts, free tiers and taxes
  • Real bills can differ because of tokenization, reasoning, tools, retries, images and audio
  • Prices depend on the public OpenRouter model catalog
  • Cost comparison does not measure quality, latency or reliability

Mydentify AI Model Cost Calculator FAQ

What is the Mydentify AI Model Cost Calculator?

It is a free web calculator that compares the monthly API cost of AI models for a workload you describe with request volume, token sizes and an expected prompt caching rate.

Is the AI Model Cost Calculator free?

Yes. The page states that no account is required and no API keys are needed. You only enter workload assumptions in the form.

Where do the model prices come from?

The calculator refreshes the public OpenRouter model catalog every hour, so rates track the catalog rather than a vendor invoice.

How is the monthly cost calculated?

It scales each model's input, output, cache and fixed per-request prices by your monthly request volume. A cache-read price is used for cached input when the model publishes one.

Why might my real bill differ from the estimate?

The real charge can differ from the estimate because actual tokenization, reasoning tokens, tool calls, retries, images, audio and provider billing rules vary. The estimate leaves out discounts, free tiers and taxes.

Does the cheapest model work best?

Not necessarily. A lower price says nothing about quality, latency, reliability or policy fit, so test candidates on your own workload before moving production traffic.

What are alternatives to this calculator?

Alternatives include OpenRouter's model pages, LLM Price Check, the Artificial Analysis comparison pages and the pricing calculators from OpenAI, Anthropic and Google.
