Model comparison
Compare Claude Haiku 4.5 and Grok 4.20 Multi-Agent Beta using the same provider-sourced text & reasoning rubric. No mystery score and no invented benchmark ranking.
Facts checked September 14, 2026
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.
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
A compact Claude model for quick replies, classification and narrowly scoped assistants.
Haiku 4.5 uses manual extended thinking, not the adaptive thinking settings of the newer Claude models.
A specialist Grok model that sends several AI agents to investigate a difficult question in parallel, then combines their work into one researched answer.
This is a beta product, not the newest general-purpose Grok. Its interface may change, and built-in searches or code runs can add cost beyond the headline token price.
Compare the published facts
Values use each provider's own published units and limits. A blank means the provider did not publish a directly comparable value in the sources reviewed.

How to choose
Start with the job you need to complete, then validate cost, access, and policy details on your exact provider route.
Anthropic does not train on API data without express permission. Retention depends on the API feature, account agreement and cloud provider.
