What Data for This Category Looks Like
Precious metals investment research data originates from the Shanghai Gold Exchange, the London Bullion Market Association, public financial reports of mining companies, and third-party industry information platforms. Spot price data updates in real time per trading session. Futures contract prices update during trading sessions on active trading days. Industry supply and demand reports and policy updates are released weekly or monthly. Document formats include standardized market snapshots (with fields for product code, quote, price change percentage, and open interest), in-depth research reports (with ratings, target prices, and supply and demand balance sheets), and industry news updates. Quote units are typically yuan per gram (for gold) and yuan per kilogram (for silver). Some overseas products use ounces as their pricing unit.
Constraints for Model Integration and Configuration
The real-time nature of precious metals data creates timeliness requirements for model recall. High-frequency market data needs short-cycle context windows to maintain information freshness. Fields with multiple pricing units require unified unit conversion rules during model integration, to prevent unit confusion in model responses. Document lengths vary widely: market snapshots are only tens of characters, while in-depth research reports can span tens of thousands of characters. This requires adjusting segmentation and recall matching strategies. Regularly updated industry reports need a knowledge base synchronization cycle aligned with their release rhythm, to avoid the model using outdated information.
How to Set Configurations
| Configuration Item | Recommended Values | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | Adapts to the combined context length of precious metals research reports and market data, avoiding truncation of critical supply and demand data |
similarityThreshold | 0.72–0.85 | Distinguishes semantic similarity between precious metals market data and industry news, filtering out low-relevance non-precious metals content |
rerankTopN | Top 8–12 entries | Covers different types of precious metals data, balancing market detail and research report logic |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Handles large in-depth research report documents, avoiding parsing timeouts |
UPLOAD_FILE_MAX_SIZE | 200 MB | Meets the needs of batch uploading industry reports |
chunkOverlap | 150–200 characters | Retains cross-segment association information for supply and demand balance sheets in research reports |
The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Configuration Errors
- Calling an Alibaba Cloud model on FastGPT V4.9.7 returns a 400 error. Investigation shows that unit conversion prompt words unique to precious metals data were not configured. This causes the model to fail to recognize pricing unit differences between yuan per gram and ounces, triggering parameter format verification failure.
- Adding a Qwen3-235B channel results in a 404 page not found error. The root cause is either the configured API endpoint not matching the model call path for precious metals investment research scenarios, or an incorrectly filled channel identifier.
- After indexing relevant precious metals supply and demand reports, the model does not reference their content. This happens when the
chunkOverlapconfiguration is too small, truncating supply and demand balance sheets in research reports across segments. The truncated content cannot form complete semantic units for recall.
How to Verify Successful Configuration
- Upload a standard gold spot market snapshot document, and check if the parsed segments retain core fields such as product code and quote unit.
- Initiate a test call with the prompt "What is the current spot gold price?", and verify that the returned result includes matching real-time market data and the correct pricing unit.
- View the knowledge base synchronization log, and confirm that the industry report update cycle matches the configured synchronization frequency.
- Simulate an error scenario by entering an incorrect API key or address, and verify that the corresponding error prompt is triggered. This confirms the configuration verification logic is working.
