What the data for this category looks like
The financial report data for the optical and optoelectronic category mainly comes from the official disclosure platforms of the Shanghai, Shenzhen and Beijing Stock Exchanges, and the investor relations sections of listed companies. The update schedule follows fixed nodes for periodic reports: annual, semi-annual, and quarterly. Temporary announcements are updated in real time alongside business developments. The document structure includes core financial statements, operating data summaries, and business segment analysis. Fields cover total revenue, shipment volume, production capacity scale, etc., with units of RMB 100 million yuan, 10,000 units, and 1,000 square meters per month respectively. There are slight differences in the disclosure formats of segmented businesses across different companies.
What constraints do these characteristics impose on model access and configuration
The length of financial report documents varies widely, with core chapters of individual annual reports reaching several thousand characters. This requires configuring sufficient context window capacity when accessing the model to avoid truncation of key operating data. Segmented business fields have no unified format, so parameters for custom extraction rules need to be configured to adapt to disclosure differences across companies. Temporary announcements are updated in real time, so model access must support dynamically triggered call configurations to meet real-time data call requirements. Multi-source data sources require configuring parsing priorities for different files to ensure the latest disclosed announcements are prioritized. Fields with different units need standardized conversion parameters to unify data caliber and ensure analysis accuracy.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–16000 characters | The core business chapters of individual optical and optoelectronic financial reports typically range from 3000 to 8000 characters, reserving sufficient space to avoid truncation of key operating data |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Large annual report parsing requires lengthy processing time, preventing interruptions to the complete parsing process due to timeout |
UPLOAD_FILE_MAX_SIZE | 50 MB | Individual annual report PDFs typically do not exceed 20 MB, reserving space for batch file uploads with merged multiple pages |
customExtractPrompt | Extract revenue, shipment volume, and production capacity data, unify units to 100 million yuan, 10,000 units, and 1,000 square meters per month | The segmented business fields for optical and optoelectronic industries have inconsistent formats, clearly defining standardized extraction rules avoids data caliber confusion |
concurrentLimit | 3–5 concurrent calls | Matches the rate limiting thresholds of public financial report disclosure platforms and most general large model interfaces, avoiding triggering 429 errors |
similarityThreshold | 0.75–0.85 | Financial report fields have high semantic similarity, this range filters low-match irrelevant data and ensures extraction accuracy |
The parameter values provided on this page are all common recommended starting points for configuration. The actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing the settings.
Three common mistakes
- Phenomenon: A 500 error is returned when calling after accessing a local large model, and logs show abnormal model response format. Cause: The
maxContextparameter adapted to long financial report text is not configured, causing the input to exceed the model's supported upper limit and triggering an internal error. - Phenomenon: Frequent 429 status codes are returned when batch parsing optical and optoelectronic financial reports. Cause: A reasonable
concurrentLimitparameter is not set, and concurrent requests exceed the interface rate limiting threshold. - Phenomenon: Extracted operating data has inconsistent units, with cases of mixing "10,000 units" and "1 million units". Cause: Standardized conversion rules are not clearly defined in
customExtractPrompt, and the data caliber is not unified.
How to confirm the configuration is complete
- Upload a single 50-page optical and optoelectronic annual report PDF, check that no truncation prompt appears in the parsed text, and confirm that the
maxContextandPARSE_FILE_TIMEOUT_SECONDSconfigurations match the current model and document length. - Submit financial report files from three or more different companies, check that the units of the extraction results are unified, and confirm that the standardized rules of
customExtractPromptare effective. - Initiate a batch call test, observe that no 429 status codes appear in the interface return results, and confirm that the
concurrentLimitconfiguration matches the actual rate limiting requirements. - Call the model to generate a financial report analysis summary, check that the output includes core operating data, and confirm that the
similarityThresholdhas filtered low-match irrelevant content.
