This article records configuration and changes from a historical FastGPT release. Use it to understand that release, and consult the release notes for your installed and target versions before applying dependencies, configuration, or migration steps.
Unlimited Dataset Indexing
Previously, FastGPT dataset indexing included a hard limit on custom index creation. This update removes that restriction, enabling unlimited custom indexes for dataset configuration. Input text indexes, which are automatically generated during dataset ingestion, will now update independently without disrupting existing custom indexes, eliminating manual reconfiguration overhead after index updates.
Markdown Parsing Quality Fixes
The markdown parsing engine has been updated to handle Chinese-language content more accurately. The new logic detects Chinese punctuation characters placed immediately after hyperlinks and inserts consistent spacing between the link and following punctuation, improving readability of formatted documentation and chatbot responses that include both links and Chinese text.
Core Feature & API Optimizations
Prompt-Mode Tool Calls
Prompt-mode tool calls now natively support reasoning models, expanding compatibility for workflows combining logical reasoning with external tool integrations. Enhanced format validation for tool call outputs also reduces instances of empty or malformed responses, leading to more reliable tool execution.
HTTP Body Adaptation
FastGPT’s HTTP request handling has been updated to support string object types in HTTP request bodies, broadening compatibility with third-party tools and custom integrations that use this data format.
Backend Performance Improvements
Two key backend changes have been implemented to streamline large file handling: first, MongoDB file read streams have been merged to reduce redundant computational overhead. Second, storage chunk handling has been optimized to speed up large file retrieval. These changes result in significantly faster read times for large documents; specifically, the read time for 50MB PDF files is improved threefold.
