Compare prices for the same model
USD per 1 million uncached text tokens. Each cell lists input / output. Short-context Standard rates; cache, tools, regional fees, taxes and funding fees are excluded.

OpenRouter amounts are model-list rates, excluding its separately listed platform fees. A missing quote means it was not verified for this comparison; it does not establish that the provider has no such model. Unverified reference figures are not filled with older or inferred prices.
The same workload, three budgets
Example: claude-sonnet-5, 10 million input and 2 million output tokens across many short-context requests. No cache, tools or extra operations; this is not one 10-million-token prompt.
A changed token mix or context tier changes the result. For actual budgets, add billable reasoning, cache writes and tool use from your usage records.
Caching is a separate Claude budget item
Anthropic cache reads, five-minute writes and one-hour writes have different rates. Comparing a cheap cache hit with another service’s uncached input is misleading. The baseline workload below excludes caching; the full API429 table lists cache operations separately.
Choosing a family for the workload
Start with your own task set: coding, extraction, long documents or short classification. Compare accepted outputs, latency and cost per completed task. A rate table measures token cost rather than model quality or speed.
Tokenization can differ between model generations. The same text may produce different token counts, so inspect usage on a representative task. Direct Anthropic, OpenRouter and API429 also have separate keys, billing and feature availability.

Connect the model and check the result
Create an API429 key and check the permitted model IDs before migrating a workload. Keep the key on your server. Review the request contract and inspect actual usage and charges on a small representative job before increasing volume.
Sources and comparison method
Reference rates checked October 2, 2026. Recheck after a model release, promotion or pricing change. Reference figures are hidden after their review deadline; current API429 prices load from the public catalog. Neither individual contracts nor discounts are inferred.
