A tidy interface for integrating large language model (LLM) APIs such as 'Claude', 'OpenAI', 'Gemini', 'Mistral', and local models via 'Ollama' into R workflows. The package supports text, image, audio, video, and document interactions; a unified media interface for attaching inline files or uploading to provider file stores; batch request APIs for cost-efficient large-scale processing; and a pipeline-oriented interface for seamless integration into data workflows. Web services are available at < https://www.anthropic.com>, < https://openai.com>, < https://aistudio.google.com/>, < https://mistral.ai/> and < https://ollama.com>.

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, DeepSeek, OpenRouter, local models via Ollama and llama.cpp, and more, all through a single consistent interface.
.media. Upload files to provider servers for reuse via .files and upload_file().To install tidyllm from CRAN, use:
install.packages("tidyllm")
Or for the development version from GitHub:
devtools::install_github("edubruell/tidyllm")
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.
Use your coding agent from R. codex_cli() runs OpenAI's Codex CLI and vibe_cli() runs Mistral's Vibe CLI, both on your own machine, the same way claude_cli() runs Claude Code:
llm_message("Explain what a tibble is in one sentence.") |>
chat(codex_cli())
llm_message("Explain what a tibble is in one sentence.") |>
chat(vibe_cli(.model = "mistral-large-4"))
Control Gemini reasoning by level. gemini() takes .thinking_level ("minimal", "low", "medium" or "high"). Google is replacing token budgets with these levels, so .thinking_budget now warns that it is deprecated.
llm_message("What is 17 * 23?") |>
chat(gemini(.thinking_level = "high"))
Mistral Large 4. mistral() works with mistral-large-4, a reasoning model with a 512K-token context. Set .reasoning_effort = "none" to turn its reasoning off.
Fix for claude_cli(). With its tools off, claude_cli() could still read files. It no longer does. The 0.7.0 release on CRAN has the same leak.
Read the Changelog for the full list of changes.
chat(ellmer(.ellmer_chat = ...)) runs a tidyllm message through any ellmer chat object.Contributions are welcome. Open an issue or a pull request on GitHub.
