What This Category's Data Looks Like
Carbon steel market data is primarily sourced from domestic steel industry spot trading platforms and futures exchange market APIs. Real-time intraday data updates every 15 minutes. Complete daily market data generated after market close is updated after 17:00 local time. Data is stored in structured CSV or JSON format, with each row corresponding to a single carbon steel product. Fields include product name, production origin, product specifications, daily transaction price, daily settlement price, price change range, daily trading volume, daily open interest, and more. Price units are yuan per ton, trading volume units are tons, and open interest units are lots.
How These Characteristics Impact Multi-turn Dialogue and Prompt Engineering
Carbon steel product specifications are diverse. Price differences vary significantly across products with different diameters and production origins. Multi-turn dialogue must gradually guide users to clarify specific product dimensions to avoid vague or inaccurate responses. Market data updates frequently. Prompts must mandate calling the latest dataset, and prohibit use of historical data cached for more than 24 hours. There are many structured fields. Prompts must clearly specify the output field format and order to prevent irrelevant information from being included. Additionally, multi-turn dialogue must retain the user-specified target product context to avoid mixing up market data for different products and ensure interaction accuracy.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
systemPrompt | Base responses on the latest carbon steel market data, only return the following fields: product name, origin, product specifications, daily transaction price, price change range, daily trading volume. Retain user-specified product dimension context during multi-turn dialogue, prohibit use of historical data older than 24 hours | Carbon steel data updates frequently and has complex specifications, requiring clear constraints on output scope and context retention rules |
maxContext | 8000–12000 characters | Structured carbon steel market data documents are lengthy. Multi-turn dialogue requires retaining multiple rounds of interaction context to avoid truncating critical information |
retrievalTopK | Top 6–8 results | There are many combinations of specifications and origins for carbon steel. Sufficient candidate data must be retrieved to cover dimensions users may care about, while avoiding excessive redundant information that interferes with responses |
similarityThreshold | 0.75–0.85 | Product specification descriptions for carbon steel have minor differences. Balance retrieval precision and coverage to prevent missing qualifying market data |
modelContextWindow | Calibrated to 80% of the model's native context window | Reserve sufficient space to store multi-turn dialogue context and market data, preventing the model from generating valid responses due to context overflow |
pluginTriggerMode | Triggered by user queries | Carbon steel market data must be obtained in real time. Call the plugin to fetch latest data only when users submit queries, to avoid unnecessary calls |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material forms, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Issue: After configuring
systemPrompt, the model does not filter output fields as instructed and returns irrelevant historical data. Cause: The prompt fails to explicitly prohibit use of historical data older than 24 hours, or the prompt is not correctly loaded into the application's system prompt configuration. - Issue: Calling the carbon steel market plugin returns a "401 Unauthorized" error, or prompts for missing permissions even after configuring an API key. Cause: The plugin's API key is not correctly bound to the current application, or the plugin's authorization scope does not cover the carbon steel market data API.
- Issue: The configured AI model cannot be switched in the chat interface, and no corresponding options appear in the dropdown menu. Cause: The target model is not added to the application's model configuration list, or the model's API key is not correctly configured.
How to Verify Successful Configuration
- Manually enter a query that includes clear carbon steel specifications and origin, and check whether the fields returned by the model match the requirements specified in the configured
systemPrompt. - Submit the same query again after a 1-hour interval, and check whether the returned price change range differs from the previous result, confirming that the data update logic is active.
- Submit queries for different carbon steel product specifications, and check whether the model can correctly distinguish market data for different products without mixing up context.
- View the application's plugin call logs to confirm that the carbon steel market plugin is triggered for each query, and no unauthorized errors occur.
