Guided decoding (or interchangeably constrained decoding, structured generation) guarantees that the LLM outputs are amenable to a user-specified grammar (e.g., JSON schema, [regular expression](https://en.wikipedia.org/wiki/Regular_expression) or [EBNF](https://en.wikipedia.org/wiki/Extended_Backus%E2%80%93Naur_form) grammar).

TensorRT LLM supports two grammar backends:
* [XGrammar](https://github.com/mlc-ai/xgrammar/blob/v0.1.21/python/xgrammar/matcher.py#L341-L350): Supports JSON schema, regular expression, EBNF and [structural tag](https://xgrammar.mlc.ai/docs/structural_tag/structural_tag_api.html).
* [XGrammar](https://github.com/mlc-ai/xgrammar/blob/v0.1.21/python/xgrammar/matcher.py#L341-L350): Supports JSON schema, regular expression, EBNF and [structural tag](https://xgrammar.mlc.ai/docs/latest/structural_tag/structural_tag.html).

The structural-tag link now targets /docs/latest/, which will silently drift (or 404 again) whenever XGrammar reorganizes docs — this is the second such breakage. The adjacent source link on this same line still pins v0.1.21 while requirements.txt pins xgrammar==0.1.32. Consider pointing both at the pinned version (a versioned docs path if XGrammar publishes one) so the docs match the version actually shipped.

* [LLGuidance](https://github.com/guidance-ai/llguidance/blob/v1.1.1/python/llguidance/_lib.pyi#L363-L366): Supports JSON schema, regular expression, EBNF.

Define a structural tag and pass it to `response_format` when creating the OpenAI chat completion request.

Structural tag is supported by `xgrammar` backend only. It is a powerful and flexible tool to represent the LLM output constraints. Please see [structural tag usage](https://xgrammar.mlc.ai/docs/structural_tag/structural_tag_api.html) for a comprehensive tutorial. Below is an example of function calling with customized function call format for `Llama-3.1-8B-Instruct`.
