What the data for this category looks like
Data sources for precious metals research reports primarily include official market and analysis documents released by securities firm research institute industry reports, the Shanghai Gold Exchange, the London Bullion Market Association (LBMA), and similar entities. Update cycles cover daily post-market briefings, weekly industry supply and demand tracking, monthly price trend analysis, and quarterly and annual in-depth reports. Document structures typically include modules such as market summaries, supply and demand data, price trend charts, policy impact analysis, and investment recommendations. Fields include contract codes, quotation units (yuan/gram, US dollars/ounce), position holdings, publishing institutions, release times, and more. Some research reports include high-definition market charts.
What constraints these characteristics impose on tool calling and plugins
The multi-source data nature of precious metals research reports requires tool calling to support parallel pulling from multiple sources, to avoid timeout risks from single-source pulling. Fields with different quotation units require the tool to have built-in unified conversion logic, to prevent output confusion. Frequently updated documents require short cache validity periods for tool calls, to ensure the timeliness of returned data. The long document structure requires that the paragraph length and number of recalled content be adapted to the content density of research reports, to avoid redundancy or missing information. Documents with attached charts require the tool to support base64-format image transmission and rendering, to ensure the completeness of research report content.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
tool_call_timeout | 300 seconds | Precious metals research reports require pulling data from multiple sources; the default timeout duration is insufficient to complete requests for all data sources |
max_tool_return_chars | 8000-12000 characters | Single in-depth research report has lengthy content; this range balances context capacity and information completeness |
unit_conversion_switch | Enabled | Precious metals commonly use two quotation units: US dollars/ounce and yuan/gram. Automatic conversion is required to adapt to user input habits |
recall_top_k | Top 8 entries | Precious metals research reports have high content density; excessive recall will introduce redundant information and reduce model response quality |
plugin_stop_sequence | ["</tool_call>", "### Tool Call Ended"] | Clearly marks the termination boundary of tool calls, to prevent the model from continuing writing beyond the tool call scope |
base64_image_render_switch | Enabled | Some research reports include market charts; support for standard base64-format image rendering is required |
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, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- The symptom is that full intermediate execution logs of tool calls are displayed in the chat window. The cause is that the
tool_call_hide_logconfiguration item is not enabled. By default, full tool logs are output directly. - The symptom is that the tool call node gets stuck after execution, with no returned results and a returned status code of
408 Request Timeout. The cause is thattool_call_timeoutis not adjusted to meet the needs of multi-source pulling. The default timeout duration is too short to complete the request. - The symptom is that the model output includes unclosed tool call code blocks, or base64-format images in research reports fail to render properly. The cause is that
plugin_stop_sequenceorbase64_image_render_switchis not configured correctly, or the standarddata:image/png;base64,prefix is not added before the base64 image string.
How to confirm configurations are set correctly
- Trigger a standard precious metals research report retrieval request, check whether only the final response is displayed in the chat window with no intermediate execution logs of tool calls, to confirm that the hide log configuration is effective.
- Call the tool to pull research report data with US dollars/ounce quotation units, check whether the price fields in the returned results have been converted to the target unit, to confirm that the unit conversion configuration is effective.
- Upload a test research report containing standard base64-format images, check whether the chat window renders the images normally, to confirm that the image rendering configuration is effective.
- Customize
plugin_stop_sequenceto a specified termination string, trigger a tool call, and check whether the model output ends at that string, to confirm that the stop sequence configuration is effective.
