LLMR (version 0.6.0)

llm_fn_structured: Vectorized structured-output LLM

Description

Schema-first variant of llm_fn(). It enables structured output on the config, calls the model via call_llm_broadcast(), parses JSON, and optionally validates.

Usage

llm_fn_structured(
  x,
  prompt,
  .config,
  .system_prompt = NULL,
  ...,
  .schema = NULL,
  .fields = NULL,
  .local_only = FALSE,
  .validate_local = TRUE
)

Arguments

x

A character vector or a data.frame/tibble.

prompt

A glue template string. With a data-frame you may reference columns ({col}); with a vector the placeholder is {x}.

.config

An llm_config object.

.system_prompt

Optional system message (character scalar).

...

Passed unchanged to call_llm_broadcast() (e.g. tries, progress, verbose).

.schema

Optional JSON Schema list; if NULL, only JSON object is enforced.

.fields

Optional fields to hoist from parsed JSON (supports nested paths).

.local_only

If TRUE, do not send schema to the provider (parse/validate locally).

.validate_local

If TRUE and .schema provided, validate locally.
