What data for this category consists of
Data for this category typically comes from object storage, data warehouses, annotation platforms, and customer acceptance feedback. Daily produced documents include dataset descriptions, version records, delivery lists, and acceptance reports. Core fields include version number, sample count, delivery path, sample difference description, and acceptance conclusion. Data updates occur once per batch delivery or per version iteration. The size of a single delivery package fluctuates based on business requirements.
What constraints these characteristics impose on context and token processing
Multi-version iteration requires context to accurately associate with the dataset of the corresponding version, to avoid mixing data from different versions. Diverse document structures and fields cause fluctuations in token consumption. Overly long delivery lists or version records may exceed the token limit. Frequent version updates require a context synchronization mechanism that can quickly identify the latest dataset paths and descriptions, to prevent calling expired data. Sample difference descriptions across batch deliveries must be accurately matched during context recall, otherwise they will affect the accuracy of subsequent training or classification.
How to configure the settings
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
maxContext | Total token count of the first 10 version records + 2 delivery lists | Matches the average token consumption of single-batch delivery documents, avoids exceeding the model context limit |
quoteMaxToken | 800–1200 token | Covers the typical length of dataset descriptions and sample difference descriptions, ensures core information is fully recalled |
| Context version filtering | Only recall the version number specified in the current task | Prevents dataset data from different versions from mixing into the context, ensures data consistency |
| Maximum context window | Calibrated based on actual testing, no more than 80% of the model's supported limit | Adapts to the context processing capability of FastGPT v4.17.0, reserves redundant space for unexpected long document scenarios |
Three common misconfigurations
- Phenomenon: In a multi-knowledge base question classification scenario, only the classification result of the current question is returned. Dataset version information from the context history is not associated, causing the classification result to be incorrectly assigned to the fallback category. Cause: No version filtering rule is added to the context configuration. Only the single query data of the current input is called, and the dataset version specified in historical interactions is not associated.
- Phenomenon: After adjusting the chat record length parameter, the context does not display recalled dataset delivery list or version record content. Cause: The
maxContextconfiguration does not cover the adjusted total token amount of historical records, or the context recall logic is not bound to the dataset delivery list field of the current task. - Phenomenon: Data mixing occurs in training or classification results. Samples from different versions of datasets are called simultaneously. Cause: No version number filtering condition is specified in the context configuration. Documents from multiple versions of datasets are recalled, leading to mixed data sources.
How to confirm the configuration is complete
- View the context configuration page in the FastGPT backend, confirm that the values of
maxContextandquoteMaxTokenmatch the preset requirement document rules. - Initiate a test call, input a query containing historical version information, and check whether the recalled context only includes dataset documents of the specified version.
- View the token consumption log, confirm that the total token amount of a single call does not exceed the configured upper limit threshold.
- Simulate an interaction scenario with multi-version datasets, and verify that classification or training results only use data from the currently specified version.
