| # Function Calling |
|
|
| ## Introduction |
|
|
| Function calling aims to provide large language models with **the ability to invoke external tools**, enabling various Agentic functionalities. |
|
|
| For example, when you ask the LLM: "Help me search for information about cats", the model will call external search tools, such as search engines, and return the search results. |
|
|
| Here is the revised text, updated to reflect your new content while maintaining a formal documentation tone: |
|
|
| Currently, supported models include but are not limited to: |
|
|
| - GPT-5.x series |
| - Gemini 3.x series |
| - Claude 4.x series |
| - DeepSeek v3.2 (deepseek-chat) |
| - Qwen 3.x series |
|
|
| Mainstream models released after 2025 typically support function calling. |
|
|
| Commonly unsupported models include older models such as DeepSeek-R1 and Gemini 2.0 thinking-type models. |
|
|
| In AstrBot, web search, todo reminders, and code interpreter tools are provided by default. Many plugins, such as: |
|
|
| - astrbot_plugin_cloudmusic |
| - astrbot_plugin_bilibili |
| - ... |
|
|
| In addition to providing traditional command invocation, also offer function calling capabilities. |
|
|
| Related commands: |
|
|
| - `/tool ls` - View the list of available tools |
| - `/tool on` - Enable a specific tool |
| - `/tool off` - Disable a specific tool |
| - `/tool off_all` - Disable all tools |
|
|
| Some models may not support function calling and will return errors such as `tool call is not supported`, `function calling is not supported`, `tool use is not supported`, etc. In most cases, AstrBot can detect these errors and automatically remove function calling tools for you. If you find that a model doesn't support function calling, you can also use the `/tool off_all` command to disable all tools and try again, or switch to a model that supports function calling. |
