Data Characteristics of This Category
Precious metals-related data mainly comes from real-time market APIs of compliant precious metals trading venues, and category dynamic documents from industry news platforms. Update schedules are divided into two types: real-time market data (updated per second), and daily research reports and product manuals (updated daily or weekly). Document structures are split into structured market fields and unstructured marketing text: Structured fields include product identifier, purity grade, pricing unit (gram/kilogram/ounce), latest transaction price, price change rate, and open interest. Unstructured content includes product process descriptions, investment logic explanations, and historical price trend analysis texts.
Constraints Imposed on Model Integration and Configuration
Real-time market data updated per second requires that model call interface response delays be controlled within a reasonable range. Otherwise, price data in marketing content will lag behind actual values. Diverse pricing units require the model to complete unified mapping when processing parameters. This prevents confusion between quotation data using different units. The multi-dimensional features of structured fields require the model to support multi-field vector indexing. It cannot rely solely on single-text semantic matching. The length of unstructured marketing text varies significantly. Long documents may exceed the model's default context window. Segmentation rules must be configured to adapt to this. There are many professional terms in the precious metals field. The model must have the ability to identify and standardize professional terms. This ensures accurate expression in marketing content.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
API_BASE_URL | https://api.commodity-exchange.com/v1/precious-metals | Matches the interface address of compliant precious metals data sources, complies with access path specifications |
MAX_CONTEXT_TOKENS | 8192–16384 | Covers the full context of long texts such as precious metals research reports and product manuals, avoids content truncation |
VECTOR_EMBEDDING_MODEL | bge-large-zh-v1.5 | Adapts to semantic capture of precious metals professional terms, improves indexing accuracy for structured fields and unstructured text |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Meets the field parsing duration for batch import of precious metals market data, avoids mid-timeout interruptions |
RECALL_TOP_K | Top 8–12 results | Balances recall coverage of precious metals market data and product information, avoids recalling excessive irrelevant content |
SIMILARITY_THRESHOLD | 0.75–0.85 | Filters low-relevance non-precious metals content, ensures matching accuracy between marketing content and user queries |
The parameter values provided on this page are common recommended starting points 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 settings.
Three Common Misconfigurations
- After importing the OneAPI address and key, model calls return a "401 Unauthorized" error. The cause is failure to bind exclusive permissions for precious metals data sources, or the key configuration does not include the category access whitelist.
- Vector indexing tasks remain in the "In Progress" state for long periods with no progress. The cause is failure to enable multi-field index configuration, or the selected embedding model cannot adapt to semantic parsing of precious metals structured market fields.
- No corresponding category search results are returned when calling model-built-in tools. The cause is failure to enable tool call permissions in the model configuration, or failure to configure search keyword filtering rules related to precious metals.
How to Confirm Successful Configuration
- Submit a query containing a precious metals product name. Verify that the returned results include correct purity grades and pricing units.
- Upload a precious metals product manual document. Check the completion status of the vector indexing task, and confirm that the structured field parsing results are complete.
- Enable the model tool call function. Submit a query that requires real-time market data. Verify that the tool's returned content includes the latest data for the corresponding category.
- View model access logs. Confirm that the API request response status code is 200, with no abnormal error messages.
