FastGPT V4.7 Technical Release Updates
New Feature Additions
This release delivers targeted new capabilities for self-hosted FastGPT deployments:
- A tool calling node that allows LLMs to dynamically select workflow nodes or plugins based on user intent
- Updated classification and content extraction tools to support functionCall mode for compatible LLMs
- A new HTTP plugin for rapid plugin generation via OpenAPI specifications
- Expanded ReRank model compatibility to support Cohere's official rerank format
- Helm chart installation support for streamlined Kubernetes-based deployments
- Native variable substitution support for HTTP URLs
Configuration Parameter Reference
For LLM models that support functionCall but not native toolCall, use the following explicit configuration settings:
| Configuration Field | Accepted Value | Usage Note |
|---|---|---|
functionCall | true | Enables function call mode for supported LLMs |
toolChoice | false | Disables explicit tool selection, uses default functionCall behavior |
Set toolChoice: true to switch to explicit tool selection mode instead.
