Long-document Q&A

Which model should I use to ask questions of documents over 200,000 tokens, and what will it cost each month?

Models under 200,000 tokens of context are left out. The score weighs the context window, the input rate this long prompt pays, and a cited MRCR result from the lab. A long window is not a promise that the model uses the whole document well.

How this pick is chosen

Fifteen long questions a day. Most of the bill is the document in the prompt, not the answer.

160 models cleared the bar.303 failed the lab, provider, or specialty bar.56 failed a capability filter.0 listed at $0 were left out.0 had no usable price.

When not to use it

Skip this pick when the documents are short enough that a smaller window is cheaper, when you need retrieval over a corpus instead of one prompt, or when you want a lab-published long-context result and the card does not cite one. MRCR is one needle test, not a full reading of your files.

The reference workload is fifteen questions a day, about 180,000 input tokens and 1,200 output tokens, with a 10% cache hit. Most of the bill is the document. Prompt caching changes the number more here than on short chats.

Change the workload

Prices are USD per 1M tokens. A month is 30 days. Cache hits use the cache-read rate when the model has one; otherwise the cache field is ignored.

monthly = requests/day × 30 × (input tokens × (1 − cache hit) × input price + input tokens × cache hit × cache-read price + output tokens × output price) ÷ 1,000,000

The three cards follow the inputs. Fit, and who holds each role, stays on the reference workload.
