tidyllm

tidyllm is an R package for working with large language model APIs in data analysis workflows. It supports Anthropic Claude, OpenAI, Google Gemini, Mistral, Groq, Perplexity, DeepSeek, OpenRouter, local models via Ollama and llama.cpp, and more — all through a single consistent interface.

Features

• Multiple providers: Switch between cloud and local models using the same verb + provider pattern.
• Unified media system: Send images, audio, video, and PDFs to any provider that supports them via .media. Upload files to provider servers for reuse via .files and upload_file().
• Interactive message history: Manage multi-turn conversations with structured history automatically formatted for each API.
• Batch processing: Handle large workloads with Anthropic, OpenAI, Mistral, Groq, and Gemini batch APIs, reducing costs by up to 50%.
• Tidy workflow: Pipeline-oriented, side-effect-free design that integrates naturally with tidyverse data workflows.

Installation

To install tidyllm from CRAN, use:

install.packages("tidyllm")

Or for the development version from GitHub:

devtools::install_github("edubruell/tidyllm")

Basic Example

library(tidyllm)

# Describe an image with Claude, continue with a local model
conversation <- llm_message("Describe this image.",
                             .media = img("photo.jpg")) |>
  chat(claude())

conversation |>
  llm_message("Based on that description, what research topic could this figure relate to?") |>
  chat(ollama(.model = "qwen3.5:4b"))

For more examples and advanced usage, see the Get Started vignette.

Please note: To use tidyllm you need either a local Ollama or llama.cpp installation, or an active API key for one of the supported cloud providers. See the Get Started vignette for setup instructions.

What’s new in 0.5.0

Unified media and files system. All non-text content now attaches to messages, not to chat() call arguments:

# Inline binary — works with any provider that supports the type
llm_message("Transcribe this audio.", .media = audio_file("recording.mp3")) |>
  chat(gemini())

llm_message("Summarize this paper.", .media = pdf_file("paper.pdf")) |>
  chat(claude())

# Multiple images in one message
llm_message("Compare these two charts.",
            .media = list(img("chart_a.png"), img("chart_b.png"))) |>
  chat(openai())

# Provider Files API — upload once, reuse across requests
report <- upload_file(claude(), .path = "annual_report.pdf")
llm_message("What are the key risks?", .files = report) |>
  chat(claude())

Audio and video are supported by Gemini, OpenRouter (Gemini, Gemma 4, Qwen 3.6, and other models), Mistral (Voxtral), and llama.cpp (Ultravox, Gemma 4, Qwen2.5-Omni). The .imagefile and old provider-specific upload functions still work but now emit deprecation warnings.

OpenAI now uses the Responses API (POST /v1/responses) with reasoning effort control, built-in web search, and background deep research:

llm_message("What are the latest developments in fusion energy?") |>
  chat(openai(), .tools = openai_websearch())

llm_message("Write a detailed report on EU AI regulation.") |>
  deep_research(openai())

Similar packages

• ellmer is especially well-suited for asynchronous chats, chatbots in Shiny, and advanced tool-calling workflows. Its design philosophy differs from tidyllm: ellmer targets interactive agents while tidyllm targets data pipelines and batch operations.
• rollama is purpose-built for the Ollama API with specialized model management features not currently in tidyllm.
