Model Access and Configuration for Packaging and Printing

What the data for this category looks like

Packaging and printing investment research data mainly comes from production capacity and operating rate reports released by light industry associations, spot and futures market platforms for upstream raw and auxiliary materials such as pulp and film, packaging order ledgers of downstream fast-moving consumer goods and e-commerce, production work orders and quality inspection reports of printing enterprises, and national light industry manufacturing-related policy documents. Raw and auxiliary material market data is updated daily, industry production capacity data is updated monthly, order ledgers are updated weekly, and process specification documents are updated quarterly. The data includes structured quotation sheets (fields include product name, specification, unit price, unit), semi-structured order ledgers, and unstructured process PDFs (including parameters such as color number, die-cutting accuracy).

What constraints these characteristics impose on the model access and configuration link

Daily updated raw and auxiliary material market data requires configuring real-time synchronization trigger rules by type, to avoid data lag caused by fixed batch updates. The unit field (yuan/ton, square meter, etc.) in structured quotation sheets requires configuring field verification rules, to prevent retrieval errors caused by unit confusion. Unstructured process PDFs contain a large number of professional parameters, requiring retaining context during segmented parsing, to avoid parameter breakage after splitting. Batch import of weekly order ledgers requires adjusting sharding and timeout parameters, to adapt to scenarios with large single-batch data volume.

How to set the configurations

Configuration Item	Recommended Value Range	Rationale
`maxContext`	`16384–32768 tokens`	A single packaging and printing process specification PDF can reach thousands of characters. Superimposing multiple copies of raw and auxiliary material market data and order data requires a sufficient context window to avoid retrieval and output truncation
`UPLOAD_FILE_MAX_SIZE`	`1024 MB`	The maximum size of a single batch-imported production work order ledger or process manual usually does not exceed this value, to meet batch import requirements
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Unstructured process PDFs contain a large number of vector images and professional parameters, which take a long time to parse. Extending the timeout period avoids parsing interruptions
`chunk_size`	`1500–2000 characters`	Retains the context of professional parameters such as color number and die-cutting tolerance, to avoid parameter breakage after segment splitting that affects retrieval accuracy
`similarity_threshold`	`0.85–0.90`	Field matching for structured raw and auxiliary material quotation sheets requires high similarity, to avoid quotations from unrelated categories being mixed into retrieval results
`rag_top_k`	`Top 6 entries`	Investment research needs to balance three types of information: raw and auxiliary material market trends, process parameters, and order data. Too many recalled entries will cause context overload

The parameter values provided on this page are all conventional recommendations, used as a starting point for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing the settings.

Three common mistakes

The symptom is that the model output is truncated at 12288 tokens, displaying "exceeds reply limit". The cause is failure to adjust the maxContext parameter for long documents in packaging and printing, which causes the actual available output tokens to be compressed.
The symptom is that unit matching errors occur in imported raw and auxiliary material quotation sheets, for example, identifying pulp quotations priced per ton as priced per square meter. The cause is failure to configure field verification rules and enforce verification of the unit field in structured data.
The symptom is that a 504 status code timeout error is triggered when batch importing production work orders. The cause is failure to adjust the PARSE_FILE_TIMEOUT_SECONDS parameter to adapt to the parsing time of large batch data.

How to confirm the configuration is correct

Upload the longest single process specification PDF, check whether the parsed segments retain complete professional parameters, and adjust chunk_size until there is no parameter breakage in the segments.
Import a structured raw and auxiliary material quotation sheet, check whether the unit fields in the retrieval results match the source data, and adjust similarity_threshold until the matching accuracy meets requirements.
Initiate an investment research query that includes multiple copies of raw and auxiliary material market data and process parameters, check that the model output is not truncated prematurely, and adjust maxContext until the output length requirement is met.
Batch import 10 copies of production work order ledgers, check the import success rate, and adjust UPLOAD_FILE_MAX_SIZE and PARSE_FILE_TIMEOUT_SECONDS until the import proceeds without exceptions.
