How we price

Order

Providers are listed cheapest input rate first, then by output rate, a tie going to the creator's own listing. A provider that lists the model without a published rate sits at the end.

Prices

Base-tier, on-demand rates in USD per 1M tokens, converted at ECB reference rates where a provider publishes in another currency. Cached-input and batch rates show only where a provider publishes them. "Cheapest" marks the one provider with the lowest input and output pair; a tie wears no badge.

Cost

Input rate times the input tokens plus output rate times the output tokens, at the monthly volume set above the table. Cached-input, batch, long-context and reasoning-token billing are not modelled.

Transparency and funding

Common questions

What is Claude Haiku 5.5 good for?

Classification, extraction, routing and subagent work at high volume, with thinking depth set by an effort control. It sits at the lower-cost end of Anthropic's lineup, under Sonnet 5.5.

When is Claude Haiku 5.5 not a good fit?

Audio or video input, and closed weights, so no self-hosting. Long prompts cost more per token, since Anthropic bills prompts over 100K tokens at a higher rate, and the hardest reasoning work goes to Sonnet 5.5 and Opus 5.5.

The cheapest hosted rate is $0.10 / $0.50 per 1M tokens via Anthropic.

Its newer tokenizer counts the same text as more tokens, and manual extended thinking, assistant prefill and sampling parameters now return errors. Same text and image input.
