A 400-page trade paperback read in one pass, answered with a chapter-by-chapter summary.
Pricing verified:
Between $0.0086 and $1.68 per run, depending on the model. That is a 195× spread for the same job.
400 book pages at ~300 words per page = ~120,000 words ≈ 160,000 input tokens. A chapter-by-chapter summary of ~1,100 words ≈ 1,500 output tokens.
Cost = (input tokens ÷ 1M × input price) + (output tokens ÷ 1M × output price). Prices come from our daily-verified model data. Batch and cached-input discounts are not applied — they only ever make these numbers smaller.

“Needs chunking” means the model's context window can't hold this job in a single pass, so the real cost is higher than the figure shown and quality usually suffers.
160,000 tokens rules out most models in a single pass — this is the job that justifies a 200K or 1M context window. Below that you are chunking, and chunked summaries lose the through-line between chapters, which is the entire reason to summarise a book.
$0.0086 on GPT-5 Nano, the cheapest capable option, rising to $1.68 on GPT-6 Astra at the top end. GPT-5 Nano is the value pick at $0.0086 per run. The job is priced at 160,000 input and 1,500 output tokens — see the working below.
400 book pages at ~300 words per page = ~120,000 words ≈ 160,000 input tokens. A chapter-by-chapter summary of ~1,100 words ≈ 1,500 output tokens.
$0.172 a month on GPT-5 Nano, $0.172 on GPT-5 Nano, and $33.50 on GPT-6 Astra. Batch APIs typically halve these figures for work that can wait, and prompt caching cuts the input side further when the same context is reused.

Yes. Every figure on this page is computed from our model pricing data, which is checked daily against each provider's official pricing page. When a provider changes a price, these numbers change with it.
