What this category of data looks like
Minor metals investment research data primarily comes from public statistics released by industry associations, listed contracts on futures exchanges, production data disclosed by mining enterprises, and customs import and export declarations. Spot price data is updated per trading day. Industry supply and demand monthly reports are updated monthly. Annual capacity reports are updated quarterly or annually. Data documents include standardized quotation sheets (with fields including product name, specification, origin, daily quotation, total inventory), industry research reports, and import and export detailed lists. Most units are yuan/kilogram, yuan/ton, or ten thousand tons. Some segmented categories use tonnage or kilogram pricing.
What constraints do these characteristics impose on model access and configuration?
The multi-source nature, differentiated update rhythms, diverse field units, and varied document structures of minor metals data create multiple constraints for model access configuration. Differentiated update frequencies require configurable custom recall refresh cycles, to adapt to the different synchronization rhythms of daily-updated spot data and monthly-updated industry reports. Differentiated pricing units and field naming require configured unit mapping rules and field standardization processing logic, to prevent the model from confusing statistical definitions. The coexistence of short and long document structures requires configurable differentiated chunking thresholds, to adapt to the splitting needs of short quotation sheets and long research reports. Differences in the authority of multi-source data also require configured recall weight allocation rules, to prioritize official data released by industry associations.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_CHUNK_SIZE | 800–1200 characters | Minor metals research reports are mostly a mix of structured and unstructured content. This length can fully cover the core data of a single chapter and avoid splitting that disrupts logical coherence |
RECALL_TOP_K | Top 8–12 entries | The data volume of segmented minor metals categories is smaller than the overall non-ferrous metals market. Excessive recall will introduce irrelevant data, while insufficient recall will fail to cover all dimensions of supply and demand |
SYNC_INTERVAL | Sync spot data every 6 hours, sync industry reports every 24 hours | The update rhythms of different data sources vary significantly. Tiered configuration can adapt to data freshness requirements |
UNIT_MAPPING_RULE | Configure standardized mappings of "yuan/kilogram → yuan/ton" and "tonnage → metal tonnage" | Minor metals have diverse pricing units. Unifying units can prevent calculation and display deviations in the model |
TOOL_CALL_TIMEOUT | 300 seconds | Some minor metals supply and demand data requires pulling across multiple data sources. This duration balances request success rate and process efficiency |
PARSE_MODEL | Model that supports mixed document parsing | Minor metals data includes standardized quotation sheets and long industry research reports, requiring adaptation to mixed document parsing needs |
The parameter values provided on this page are common recommended starting points for determining configurations. 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 values.
Three common configuration errors
- The symptom is that after connecting a locally deployed open-source model, knowledge base retrieval returns no results, and the interface displays "model response is empty". The cause is that the
API_BASE_URLandAPI_KEYplaceholders for the local model are not configured, leading to incorrect request routing. - The symptom is that when calling the Gemini series models, the tool call request returns a 400 status code, and no required function call content is generated. The cause is that the
enable_function_callparameter is not enabled in the model configuration, or the tool definition JSON in an incorrect format is not passed. - The symptom is that after uploading a minor metals customs declaration form, the HS code field is missing from the parsing results. The cause is that the
CUSTOM_FIELD_MAPPINGrule is not configured, and the dedicated field extraction logic for minor metals declaration forms is not specified.
How to confirm the configuration is correct
- Initiate a query request targeting the minor metals category, verify that the pricing units of the returned data match the preset standardization rules, and adjust configuration items until the units are unified.
- Upload a single minor metals industry research report, check the number and length of parsed chunks, and adjust
PARSE_CHUNK_SIZEuntil it meets the document structure requirements. - View tool call logs to confirm that the request timeout meets business requirements, and adjust
TOOL_CALL_TIMEOUTuntil frequent timeout errors no longer occur. - Trigger a synchronization task for a specified data source, verify that the synchronization cycle matches the configured
SYNC_INTERVALrules, and adjust tiered configurations until they cover the update rhythms of all data sources.
