From 4f0ba34a4b0a53ded7ebbc9393efc5db22587dd4 Mon Sep 17 00:00:00 2001 From: Benjamin Oldenburg Date: Mon, 25 Aug 2025 17:53:53 +0000 Subject: [PATCH 1/7] feat: Add XML tool call processing system for GLM-4.5 models - Add BaseXMLToolCallProcessor abstract class for extensible XML processing - Implement GLM45ToolCallProcessor for GLM-4.5 specific XML format - Add XMLToolCallProcessorFactory with factory pattern for processor creation - Extend TemplateMetadata with XML support fields (tool_call_format, xml_processor_type) - Enhance ToolCallProcessor with XML routing and from_xml() method - Fix Tool class import issues in tools.py - Add comprehensive test suite with 16 passing tests - Add complete implementation documentation This enables GLM-4.5 models to work with TabbyAPI's tool calling system by converting their XML format to OpenAI JSON format seamlessly. The system is backward compatible and provides a foundation for other XML-based models. --- common/templating.py | 15 ++ docs/GLM-4.5-Tool-Calling-Implementation.md | 249 +++++++++++++++++ endpoints/OAI/utils/chat_completion.py | 20 +- endpoints/OAI/utils/tools.py | 46 +++- endpoints/OAI/utils/xml_tool_processors.py | 163 ++++++++++++ tests/test_xml_tool_calls.py | 280 ++++++++++++++++++++ 6 files changed, 767 insertions(+), 6 deletions(-) create mode 100644 docs/GLM-4.5-Tool-Calling-Implementation.md create mode 100644 endpoints/OAI/utils/xml_tool_processors.py create mode 100644 tests/test_xml_tool_calls.py diff --git a/common/templating.py b/common/templating.py index cc0cceb1..3c223c20 100644 --- a/common/templating.py +++ b/common/templating.py @@ -30,6 +30,9 @@ class TemplateMetadata: stop_strings: List[str] = field(default_factory=list) tool_start: Optional[str] = None + tool_end: Optional[str] = None + tool_call_format: str = "json" # "json" or "xml" + xml_processor_type: Optional[str] = None # "glm45", "custom", etc. class PromptTemplate: @@ -76,6 +79,18 @@ async def extract_metadata(self, template_vars: dict): if isinstance(template_module.tool_start, str): template_metadata.tool_start = template_module.tool_start + if hasattr(template_module, "tool_end"): + if isinstance(template_module.tool_end, str): + template_metadata.tool_end = template_module.tool_end + + if hasattr(template_module, "tool_call_format"): + if isinstance(template_module.tool_call_format, str): + template_metadata.tool_call_format = template_module.tool_call_format + + if hasattr(template_module, "xml_processor_type"): + if isinstance(template_module.xml_processor_type, str): + template_metadata.xml_processor_type = template_module.xml_processor_type + self.metadata = template_metadata return template_metadata diff --git a/docs/GLM-4.5-Tool-Calling-Implementation.md b/docs/GLM-4.5-Tool-Calling-Implementation.md new file mode 100644 index 00000000..be2c8ab2 --- /dev/null +++ b/docs/GLM-4.5-Tool-Calling-Implementation.md @@ -0,0 +1,249 @@ +# GLM-4.5 Tool Calling Implementation for TabbyAPI + +This document describes the XML-based tool calling support implemented for GLM-4.5 models in TabbyAPI. + +## Overview + +GLM-4.5 models generate tool calls in XML format, which differs from the OpenAI JSON format that TabbyAPI expects.
