llm_fn: Apply an LLM prompt over vectors/data frames

Description

Apply an LLM prompt over vectors/data frames

Usage

llm_fn(
  x,
  prompt,
  .config,
  .system_prompt = NULL,
  ...,
  .return = c("text", "columns", "object")
)

Value

For generative mode:

• .return = "text": character vector

• .return = "columns": tibble with diagnostics

• .return = "object": list of llmr_response (or NA on failure) For embedding mode, always a numeric matrix.

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).

.return

One of c("text","columns","object"). "columns" returns a tibble of diagnostic columns; "text" returns a character vector; "object" returns a list of llmr_response (or NA on failure).

  llm_fn(words, "Classify '{x}' as Positive/Negative.",
         cfg,
         .system_prompt="One word.",
         .return="columns")
