What this category of data looks like
Data for this category comes from the national unified construction project environmental impact assessment declaration and approval system, ecological environment zoning control results, pollution discharge permit platform, and monitoring data. Update frequency is irregular. Daily processed documents include environmental impact assessment reports or report forms, approval applications, public participation explanations, technical assessment opinions, and environmental impact assessment approvals. Documents contain core fields such as project category, environmental impact assessment level, pollution prevention measures, public participation content, and approval document number. There is no fixed uniform single-document length standard.
What constraints do these characteristics impose on the "model access and configuration" link
For the model access process of FastGPT v4.17.0, the data characteristics of this category impose multiple constraints. Multi-source and irregularly updated data requires configuration to adapt to documents in different formats. Sufficient context space must be reserved to cover complete approval materials. Diverse document structures and large field differences require model configuration to support accurate identification of core content related to approval, and avoid interference from redundant information. Data is linked to project construction and approval compliance, which requires model output to be rigorous and accurate. API calls must ensure data security.
How to set the configuration
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 token | Environmental impact assessment reports are usually lengthy, and need to cover complete declaration materials and approval opinions to avoid content truncation |
maxTokens | 2000–3000 token | Service consultation replies need to accurately output conclusions related to approval, control the length of single-round output, and avoid redundancy |
quoteMaxToken | 1500 token | Core reference fragments of approval documents must be retained to ensure that reply content complies with official approval requirements |
temperature | 0.2–0.4 | Environmental impact assessment replies need to be rigorous and accurate, reduce the randomness of model output, and avoid non-standard content |
AIPROXY_API_ENDPOINT | Official designated access address of the target model | Ensure normal operation of the model call link, and complete legal forwarding of model requests |
AIPROXY_API_TOKEN | Valid identity key assigned by the platform | Complete identity verification for model calls, and ensure the legality of calls |
Three common mistakes
- Symptom: An error is prompted when clicking test after configuring the model, but the reference link runs normally. Cause: The
maxContextparameter is not configured correctly. The context length limit is triggered during testing, while the document fragments used in the reference link do not trigger full verification. - Symptom: The model parameter configuration entry cannot be found, and rearrangement-related configurations are mistakenly placed in the knowledge base retrieval module. Cause: The configuration boundary between model access and knowledge base retrieval is confused, and operations are not performed on the dedicated configuration page of the corresponding model.
- Symptom: A timeout error occurs when calling the model. Cause: The long text characteristics of environmental impact assessment documents are not adapted. The
maxContextconfiguration is too small, causing the model processing to time out, or the API endpoint is configured incorrectly, causing link delay.
How to confirm that the configuration is complete
- Enter the model management page in the FastGPT v4.17.0 backend, and check that the filled content of
AIPROXY_API_ENDPOINTandAIPROXY_API_TOKENmatches the official documentation of the target model. - Upload an environmental impact assessment approval application document, initiate a test conversation, and check whether the model output includes core information such as project category and environmental impact assessment level in the document.
- Adjust the
temperatureparameter to the range of 0.2–0.4, compare the differences between the two output results, and confirm that the output remains rigorous and accurate. - View the model call log, confirm that the actual usage values of
maxContextandmaxTokensare within the configured range, and there is no abnormal content truncation.
