Context and Token for Glass Industry Investment Research

What the data for this category looks like

Glass industry investment research data sources include float glass production capacity data released by industry associations, glass price quotes from commodity exchanges, photovoltaic glass application research reports released by securities firms, and order statistics data from downstream construction and automotive industries.

Update frequency falls into three categories:

Real-time price data is updated daily
Weekly production capacity and inventory data is updated weekly
Monthly industry analysis research reports are updated monthly

Document formats include structured market tables, unstructured PDF research reports, and Excel-format historical datasets. Common fields include float glass thickness (unit: mm), flat glass price (unit: yuan/weight box), soda ash procurement cost (unit: yuan/ton), and photovoltaic glass coating rate.

Constraints on Context and Token Processing

Glass investment research data includes both structured market fields and unstructured research report content. Units vary significantly across different fields. Units must be unified when splicing contexts, otherwise invalid token consumption will increase.

Frequently updated real-time market data requires frequent context refreshes. If the context window is too small, the latest core data cannot be retained.

Downstream applications cover multiple scenarios including construction, photovoltaic, and automotive. Associating multi-source data will greatly increase the context token length. A balance must be struck between the number of recalled entries and token limits.

Individual industry research reports are lengthy. Improper segmentation will destroy logical connections between data and reduce the accuracy of investment research conclusions.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`maxContext`	`8000–12000 characters`	Covers core research reports and real-time market data for 1 to 3 quarters, balances multi-source data splicing and large model token limits
`recall count`	`Top 8–12 entries`	Single documents in glass investment research data have moderate length. Too many recalled entries will cause token overflow, while too few will result in loss of key production capacity and price data
`reranked return count`	`Top 5–7 entries`	Core investment research indicators for glass are concentrated in a small number of highly relevant documents. Too many reranked results will increase token consumption
`segment length`	`1000–1500 characters`	The length of individual chapters in glass industry research reports is mostly over 1000 characters. Too long segments will cause single-segment token limits to be exceeded, while too short segments will destroy data logic
`UPLOAD_FILE_MAX_SIZE`	`500 MB`	Covers complete quarterly-level glass investment research datasets, including a large number of historical market Excel files and high-definition research report PDFs
`PARSE_FILE_TIMEOUT_SECONDS`	`120 seconds`	Parsing large glass production capacity report PDFs requires a long processing time to avoid parsing failures caused by timeouts

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

Three Common Configuration Mistakes

Symptom: The rerank error alert is triggered, and logs show empty return results. Cause: The configured reranked return count exceeds the maximum input token limit supported by the reranker model. Single recalled documents for glass investment research are too long, causing spliced content to exceed model limits.
Symptom: The LLM returns LLM model response empty, and logs show a token overflow error. Cause: The maxContext value is not restricted. Spliced multi-source glass data exceeds the context window supported by the large model, preventing the model from generating a reply.
Symptom: Context is lost during continuous conversations, and historical investment research conclusions cannot be associated. Cause: Session context storage is not enabled, or the maxContext configuration is too small to retain token content from historical interactions.

How to Verify Correct Configuration

Upload a single glass industry research report, and confirm that the parsed segment length matches the configured segment length, with no forced truncation or logical breaks.
Initiate a multi-condition search including glass price, production capacity, and downstream orders, and verify that the returned recall count and reranked return count fall within the configured range.
Initiate multiple consecutive rounds of investment research conversations, and confirm that historical interaction content is retained in the current context window with no content loss.
Test uploading a glass dataset of the maximum configured size, and confirm that the parsing process has no timeout errors matching the PARSE_FILE_TIMEOUT_SECONDS setting.
