What the data for this category looks like
Rail transit equipment declaration materials and case review data originate from enterprise R&D design systems, quality control archive libraries, and special declaration folders. The data is generated gradually along the full process of R&D and declaration for single-batch equipment, and is archived to a compliant archive library after review. The document structure mixes structured parameter tables and long text descriptions. Fields include equipment model, test working conditions, compliance thresholds, review transfer nodes, and rectification instructions. Units include millimeters, kilonewtons, kilometers per hour and other rail transit-specific metrological identifiers.
What constraints these characteristics impose on the model access and configuration link
The mixed structure of structured parameters and long text in rail transit equipment declaration materials requires the model to support both structured field extraction and long context understanding. Therefore, the context window configuration must adapt to the overall length of a single material. The precise matching requirement for dedicated measurement units and compliance thresholds requires that the temperature parameter of the model call be controlled within a reasonable range to avoid results that do not meet industry standards. The multi-file association attribute of single-batch declaration cases requires the access model to handle cross-document associated retrieval, so reasonable context association parameters must be configured. The timeliness requirement of the declaration process requires that the call timeout setting match the conventional time consumption of the review link to avoid excessive waiting affecting process progress.
How to set the configuration
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Range | Rationale |
|---|---|---|
maxContext | 8000–12000 token | Adapt to the average length of a single rail transit equipment declaration material, covering structured parameters and supporting description texts |
temperature | 0.1–0.3 | Reduce hallucination risks, ensure that expressions of compliance thresholds and dedicated units accurately match industry standards |
maxTokens | 2000–3000 token | Limit single-round output length to avoid review opinion results exceeding the record space of the case |
toolChoice | auto | Support on-demand calling of document extraction tools to adapt to the needs of multi-material associated review |
AIPROXY_API_ENDPOINT | Fill in dedicated nodes according to the deployment environment | Ensure network stability of model calls and adapt to access rules of enterprise internal networks |
AIPROXY_API_TOKEN | Key bound to enterprise exclusive permissions | Ensure the security of the call link and comply with data security requirements of state-owned enterprises and public institutions |
Three Common Misconfigurations
- Long unresponsiveness during a call, with the interface showing a timeout status code. The cause is that the
maxContextconfiguration value exceeds the context upper limit supported by the model, resulting in excessively long model loading and inference time. - After configuring
AIPROXY_API_TOKEN, the call fails and returns a permission error. The cause is that the key is not bound to the access permission of the corresponding model, or scenario-specific access rules are not configured in the proxy node. - The text extraction node returns an empty compliance threshold field. The cause is that the matching rules for rail transit equipment-specific metrological identifiers are not clearly specified in the prompt, so the model cannot accurately identify dedicated units such as millimeters and kilonewtons, resulting in extraction failure.
How to confirm the configuration is correct
- Upload a single typical rail transit equipment declaration material, trigger a model call, and check whether the returned result contains complete structured parameters and description texts.
- Adjust the
temperatureparameter, call the same test material multiple times, and confirm that there is no obvious deviation in the expression of compliance thresholds in the returned results. - Check the call log to confirm that the configuration values of
AIPROXY_API_ENDPOINTandAIPROXY_API_TOKENmatch the deployment environment and have no format errors. - Trigger a multi-material associated review test, confirm that under the
toolChoiceconfiguration, the model can automatically call the extraction tool for associated documents and complete cross-file information integration.
