What the Data for This Category Looks Like
Ledger data for advanced chemical materials originates from daily production shift feeding records, batch test reports from the quality inspection center, raw material inbound and outbound ledgers from the supply chain department, and formula iteration documents from the R&D department. Data is updated in real time alongside production batches, or synced in batches once daily. A single ledger document includes fields such as batch number, raw material name, feeding quantity, test indicators including purity and viscosity, inbound time, and finished product model. Field units include kilograms, percentage, millipascal-seconds, hours, and others. Ledger entries for different batches are independent. Associated information must be linked using batch numbers.
Constraints Imposed on Multi-turn Dialogue and Prompt Engineering
The batch association feature of advanced chemical material ledgers requires multi-turn dialogues to bind to a unique identifier. This prevents mixing data across different batches. Professional test indicator units must be explicitly required in prompts. This stops the model from converting or losing unit information, which would reduce report professionalism. Data updates occur frequently, and single-batch documents are lengthy. This requires limiting the context window scope. Limiting the scope avoids loading redundant or outdated data, which can cause response delays or content truncation. Ledgers contain both production and R&D content. Prompts must clearly define query scopes. This prevents the model from confusing different types of document information and generating results that do not meet business requirements.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Context window size | 8000–12000 token | Matches the total length of a single batch ledger plus associated reports to avoid truncating critical data |
chatId binding rule | Bind to production batch number | Ensures multi-turn dialogues only associate with ledger data for the corresponding batch, avoiding cross-batch confusion |
messages history truncation threshold | Retain the most recent 10 dialog turns | Filters redundant history to prevent context overload from affecting response speed |
| Prompt format verification switch | Enabled | Forces the model to output standard formats compliant with ledger reports to match business requirements |
variables preset parameters | Fill in batch number, test indicator range | Provides clear query constraints for the model to narrow the search scope |
| Maximum response token count | 2000–3000 token | Adapts to the standard output length of a single report to avoid overly long outputs |
Three Common Misconfigurations
- Issue: After calling the API to upload ledger files, the dialogue node cannot read the file content. Cause: No associated parameters for file reading are configured in
variables, so the model cannot locate the uploaded file path. - Issue: The output of the AI dialogue node is directly returned to the dialogue interface, and cannot be extracted separately as a report result. Cause: The independent result output setting is not enabled, and the node output is bound to the dialogue flow by default.
- Issue: After initiating multiple consecutive queries, the model forgets the previously specified batch number and generates incorrect ledger summaries. Cause:
chatIdis not bound to a fixed batch number, causing the context to lose batch association information.
How to Verify Proper Configuration
- Enter a test batch number, check whether the model only returns ledger data for the corresponding batch to confirm that the
chatIdbinding takes effect. - Trigger the dialogue node, verify that the node output only contains report content with no extra dialogue prompts to confirm that the output settings are correct.
- Initiate 3 consecutive queries about different batches, confirm that the model can correctly distinguish batches to verify that the context memory function works properly.
- Submit a custom JSON format requirement, check whether the model output matches the preset field structure to confirm that the format verification switch is enabled.
