Function Documentation

create_engine_vocabulary()

kbnf.Vocabulary formatron.integrations.vllm.create_engine_vocabulary	(	AnyTokenizer	tokenizer,
		typing.Optional[list[typing.Callable]]	vocab_processors = None )

Create a vocabulary for the KBNF engine.

Parameters

tokenizer	The tokenizer.
vocab_processors	List of callables with signature (token_to_char: typing.Dict[bytes, bytes])->None. Callables can be used to "unmangle" encoded characters to original characters. If None, processors will be auto-detected.

create_formatters_logits_processor()

FormattersLogitsProcessor formatron.integrations.vllm.create_formatters_logits_processor	(	LLM	llm,
		typing.Sequence[FormatterBuilder | None] | FormatterBuilder	formatter_builders,
		typing.Sequence[EngineGenerationConfig]	configs = None,
		typing.Optional[list[typing.Callable]]	vocab_processors = None )

Create a formatter logits processor.

Parameters

llm	The LLM.
formatter_builders	The formatter builders.
configs	The engine generation configurations.
vocab_processors	List of callables with signature (token_to_char: typing.Dict[bytes, bytes])->None. Callables can be used to "unmangle" encoded characters to original characters. If None, processors will be auto-detected.
