Review a Large Exhibition Archive with Kimi K3

An exhibition archive can contain an inventory, draft wall labels, installation photographs and several revisions of the same catalog. The useful review is the one that tells the editor which label to change and why, rather than producing another general summary. Use Kimi K3 to compare the relevant extracted text, adding page images when layout or annotations affect the answer. The SpicyAPI endpoint accepts text and image URL parts; it does not accept a PDF or other file part directly. Extract the text first, preserve page labels, and add images only where layout or visible details are necessary to answer the question.

Its million-token input window can hold a large review packet, but the output should still answer a specific question: which figures disagree, what the source actually says, or which visual claim lacks evidence. This guide builds a review of a small fictional exhibition catalog rather than asking for a generic document summary.

Current K3 contract

See the Kimi K3 endpoint. The listed output ceiling is an API limit, not a practical recommendation to request a million-token answer. For a short field comparison, use reasoning_effort: low with an 8,000-token budget as in the example. Reasoning uses billed output tokens too; leave room for the answer. If finish_reason is length, lower effort or increase the budget before a new attempt. Reserve high or max effort for ambiguous conflicts across documents.

The current listing is unrestricted. For adult creators, this is relevant when choosing a reviewer for their own material, but it does not establish factual accuracy or authorize claims about a person’s identity from an image. The example here uses fictional inventory data and a safe editorial illustration.

Preserve the difference between a record and a picture

Suppose an inventory contains:

• R1: title Night Water, dimensions 80 × 60 cm, medium oil on canvas.
• R2: title Cobalt Window, dimensions 60 × 40 cm, medium unspecified.
• Draft wall text: “Cobalt Window is an 80 × 60 cm oil painting.”

The draft appears to have borrowed both dimensions and medium from R1. The title links it to R2, whose dimensions differ and whose medium is unknown. A blue-toned image does not establish that its title is Cobalt Window, and visible texture alone should not settle the medium when the catalog lacks that fact.

For a text-only check, send those three records with their labels. Ask for each disputed field, the source supporting the finding and a proposed correction. A useful correction is “Cobalt Window, 60 × 40 cm; medium not specified in the supplied inventory.” Do not fill in “oil” simply to make the wall label feel finished.

Try it in Playground first

1. Open Kimi K3 and choose the Playground tab.
2. Under System prompt, paste the instruction from the script below (SYSTEM).
3. In Message to the model, paste R1: Night Water; 80 x 60 cm; oil on canvas., R2: Cobalt Window; 60 x 40 cm; medium unspecified. and D1: Cobalt Window is an 80 x 60 cm oil painting.
4. Set the effort selector to Low and send. The dimensions should be contradicted by R2 (60 × 40 cm) and the medium reported as unsupported, not filled in.

Run the text comparison before adding images

Install the client with python3 -m pip install openai, save the following Python script as review_catalog.py, set SPICY_API_KEY from API Keys, and run python3 review_catalog.py. No asset URL needs replacing: the first comparison is text-only. Running it creates one billable request.

The validator checks both disputed fields. It rejects a finding about R1, a quotation that is not the supplied record, an omitted medium check, or an invented replacement medium. These fixture-specific values make the acceptance test concrete; a production reviewer must map findings to its own source records.

The chat documentation covers streaming and recovery for longer document packets.

Let an Agent prepare the call

For repeated document review, ask your coding Agent to use the SpicyAPI Skill: “Read moonshot/kimi-k3/chat, then adapt the example to my input; show the request before running it.” The CLI lookup is spicyapi models get moonshot/kimi-k3/chat --json; the MCP lookup is spicyapi_model_get with model: "moonshot/kimi-k3/chat". Chat calls use a compatible client or the chat API; the media task commands do not generate chat replies.

Prepare pages and add an image only where it helps

For an already searchable PDF, a local tool such as Poppler preserves the page layout: extract searchable text with pdftotext -layout catalog.pdf catalog.txt, and render only a disputed page with pdftoppm -f 18 -singlefile -scale-to 2000 -png catalog.pdf page-18.

Inspect the text before sending it: a two-column catalog can interleave artwork titles, dimensions and footnotes. Label the selected lines P018 and the associated record R2. For scanned pages, run OCR first and keep the page image beside the extracted text; an OCR reading of 8O is not a verified 80.

Attach the rendered page as an image input next to its record ID and a question about the printed dimensions. Use your own reachable image URL; the user message then carries a text part and an image part (image message examples):

{"role": "user", "content": [
  {"type": "text", "text": "R2: Cobalt Window; 60 x 40 cm; medium unspecified. Image P018 is the page for R2; use it only to check visible page content. Identify errors in D1."},
  {"type": "image_url", "image_url": {"url": "https://YOUR-ASSET-HOST.example/page-18.png", "detail": "high"}}
]}

In the system prompt, ask it to keep text evidence separate from visual observations and not to infer a title or artist from appearance.

Keep the original text records in that message when asking for a combined review. Use an image when a handwritten correction, row alignment or struck-out number changes the answer; omit it when the text already resolves the discrepancy. An installation photograph cannot establish the medium or title merely because its colours resemble the catalog description.

Build a larger document packet without losing citations

Export text with page identifiers such as P001 and preserve table headers alongside rows. A number separated from its unit or column label can become ambiguous. If extraction interleaves a two-column page, correct the reading order before asking the model to interpret it.

Add page images for questions that depend on layout, diagrams, annotations or visible content missing from extraction. Keep a text line before each image that names its page ID and role. Do not ask the model to reconstruct which image belongs to which page from ordering alone when the packet can label that explicitly.

When a table continues across pages, repeat the relevant column headers in the extracted text and state that the rows continue. For a mismatch review, ask for only the affected rows and their source IDs. A full paraphrase of every page costs output tokens without necessarily helping you find the disagreement.

Separate unreadable from absent. If a page image is too small to read, the review should say the detail is unreadable; it should not conclude that the source contains no value. Supply a clearer crop or the extracted line to resolve that specific problem. Increasing reasoning effort cannot create pixels or text that were never supplied.

Distinguish a contradiction from a different measurement

For the original fictional packet, the finished wall-label correction is “Cobalt Window, 60 × 40 cm; medium not specified in the supplied inventory.” The review should contain two findings, not merge the unsupported medium into the contradicted dimensions.

When the page image is worth including

Images help when extraction loses a relationship: an annotation points to one row, a crossed-out number sits beside its replacement, or a caption is attached to the right of two pictures. Add the relevant page or crop and label exactly what visual relation needs checking. Sending every page image simply because the model accepts images increases the packet without making every question visual.

A text record can establish a title or artist only when it maps that name to the image. Visual similarity alone is not a reliable identity source. In a creator's character sheet, label the approved character ID and image version yourself; ask K3 to compare visible clothing or prop details rather than identify a real person or infer unseen facts.

The final report can then be short: draft location, disputed field, source evidence, status and proposed wording.

Price the review packet

USD prices per million tokens are $2.70 input, $0.30 cached input and $13.50 output. A packet of 80,000 uncached input tokens with 8,000 billed output tokens costs $0.324. With 60,000 cached input tokens and 20,000 uncached input tokens, the same output costs $0.180. These examples budget the full 8,000-token output allowance; actual output can cost less.

These estimates use token counts, not PDF pages. Page count does not determine token usage, and an image’s contribution should be reconciled from the actual usage rather than guessed from its dimensions. For repeated review questions, cached-read pricing applies only where a cache hit is reported.

For a local discrepancy, sending the three relevant records costs less input than sending a whole archive. For an unknown cross-document contradiction, a wider packet may be necessary. Decide from the question rather than filling the available context window by default.

Turn findings into edits

Before accepting a finding, locate its quoted evidence in the supplied record. For the exhibition example, verify that the result attributes 60 × 40 cm to R2 and keeps the medium unknown. If it labels an image by its dominant color alone, remove that inference and restate the record-to-image mapping.

If the answer returns valid JSON but omits a disputed field, add the required fields to the instruction and validate them in your application. JSON-object mode shapes the response; it does not prove that the source IDs exist or that the corrections are right.

If an image cannot be fetched, correct its access or URL and resend the relevant page. If the API rejects a PDF part, convert the document into supported text and images. If the report becomes too long, request only unresolved findings, not another complete summary.

K3’s useful role here is to bring textual and visual evidence into one review. The finished deliverable should be a small set of traceable corrections, with unknowns left visible for the editor to resolve.

Choose the review scope

• One disputed label: send the label and the relevant approved record; a whole archive is unnecessary.
• A repeated cross-document inconsistency: send the relevant inventory, draft and revision history with page IDs so the reviewer can connect them.
• A layout-dependent question: add the particular page image and its record mapping, keeping visual observations separate from catalog facts.

K3 is useful when those sources need to be reconciled in one pass. The deliverable is a traceable correction and a clear unresolved list; the large context window is capacity, not a reason to request a longer report.
