Estimate your cost

Set your usage. Your estimate updates as you type.

Example: 6,000 input tokens for 10 pages, plus a 500-token summary. Page lengths vary; adjust the numbers below.

One run sends your input to the model once and receives an answer. Tokens are pieces of text: input is what you send, output is the answer you receive.

How this estimate works

Estimates exclude taxes, tools, cache storage/writes, free allowances and custom discounts. Image estimates cover output only, not prompt or reference-image charges. Quality modes differ by model. Unlisted settings are not treated as free.

Quick take

Claude Haiku 4.5

A compact Claude model for quick replies, classification and narrowly scoped assistants.

Best for

  • Data extraction
  • Request routing

Watch out for

Haiku 4.5 uses manual extended thinking, not the adaptive thinking settings of the newer Claude models.

Mistral Small 4

Mistral's lower-cost open model that combines normal instruction following, reasoning, coding, vision, and agent tools in one endpoint.

Best for

  • Cost-sensitive production assistants
  • Coding and tool use on one flexible model
  • Self-hosted text-and-image applications

Watch out for

Sparse activation lowers inference work but does not make the full 119B checkpoint small. Size hardware around the actual quantization and context you plan to serve.

How to choose

Compare the job, not the hype.

Start with the job you need to complete, then validate cost, access, and policy details on your exact provider route.

Claude Haiku 4.5

Anthropic does not train on API data without express permission. Retention depends on the API feature, account agreement and cloud provider.

Mistral Small 4

Mistral's commercial terms exclude model training by default except when a customer opts in or uses designated Labs or preview models. Self-hosting keeps inference data under the operator's controls; hosted API retention is generally 30 days unless zero data retention is enabled.
