What data looks like for this category
Data for software development investment research originates from code repository commit records, requirement specification documents, API interface definitions, test performance reports, and industry technical white papers. The update rhythm adjusts with project iterations: core code changes are updated in real time, while requirement documents are updated with version iterations. Document structures include code snippets, interface parameters, dependency library versions, performance metrics, test cases, and more. Fields include commit ID, interface path, response latency, version number, and more. Units include milliseconds, version number formats, character length, and more.
Constraints imposed by these characteristics on model access and configuration
The characteristics of software development investment research data impose multiple constraints on model access and configuration. Long code snippets and structured documents consume large amounts of context window space, requiring targeted configuration of chunking rules and recall thresholds. Real-time updated code commits and requirement iteration data require the knowledge base synchronization mechanism to support incremental updates, avoiding resource overhead from full synchronization. Fields with specific units such as commit ID and response latency require the model to accurately match field formats, so recall field weights and matching rules must be adjusted. Document structures vary widely across different projects, so reserved configuration items are needed to adapt to custom field parsing.
How to set configurations
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapt to the length of most code snippets and structured documents, avoid single chunks exceeding the model's context limit |
chunkOverlap | 100–200 characters | Preserve contextual association of code blocks, avoid breaking complete logic of functions or classes during chunking |
maxContext | First 80% of the model's native context | Reserve space for tool calling and result concatenation, adapt to multi-turn conversation needs in investment research scenarios |
similarityThreshold | 0.75–0.85 | Accurately match structured content such as code snippets and interface definitions, avoid low-relevance recall |
syncInterval | 300 seconds | Adapt to the iteration rhythm of software development projects, balance real-time performance and resource consumption |
toolCallStrategy | Trigger based on document tags | For different types of knowledge bases such as code repositories and API documents, call corresponding tools to handle code parsing and interface queries |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material formats, data volume and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Phenomenon: After uploading code documents exceeding the model's native context length, the interface prompts "context overflow" and returns status code 413. Cause: The
maxContextparameter is not adjusted to adapt to the total document length, and reasonable chunking rules for splitting long code documents are not configured. - Phenomenon: The AI cannot automatically identify the code parsing or interface query tool to call, and directly returns a generic answer. Cause: The
toolCallStrategyis not configured to associate knowledge base types with tools, and the model has not established a mapping relationship between document tags and tool calls. - Phenomenon: After deploying version 4.8.22 locally, calling a specified external model results in no response, and the interface displays "model connection failed". Cause: The API key and exclusive interface address are not correctly filled in the model configuration page, and the request parameter format of the model is not adapted.
How to confirm the configuration is correct
- Upload a code document containing a complete function, check whether the chunked fragments retain the function definition and core logic, to verify the rationality of the chunking configuration.
- Initiate a conversation containing code field queries, check whether the model automatically calls the corresponding tool to handle code parsing, to verify the configuration effect of the tool call strategy.
- View the model connection logs, confirm there are no errors such as "connection timeout" or "invalid key", to verify the correctness of the external model configuration.
- Upload multiple software development documents with different structures, check the field matching accuracy of recall results, and adjust the matching threshold to a level that meets business requirements.
