Overview

About

Maintained by Troy HernandezCRAN page ↗GitHub ↗Issues ↗

A minimal-dependency client for Large Language Model chat APIs. Supports 'OpenAI' https://openai.com/, 'Anthropic' 'Claude' https://claude.com/, 'Moonshot' 'Kimi' https://www.moonshot.ai/, 'OpenAI' 'Codex' subscription endpoints, 'Ollama' https://ollama.com/, and other 'OpenAI'-compatible endpoints. Includes an agent loop with tool use and a 'Model Context Protocol' client https://modelcontextprotocol.io/. API design is derived from the 'ellmer' package, reimplemented with only base R, 'curl', 'jsonlite', and 'tinyoauth'.

Changes in 0.1.9

New openai_compatible provider: point chat(), agent(), and chat_session() at any OpenAI-compatible gateway (OpenRouter, DeepSeek, corporate proxies). The base URL comes from llm_base() or OPENAI_COMPATIBLE_BASE_URL ("/chat/completions" is appended, so include any /v1 prefix the gateway expects); the key from llm_key(), OPENAI_COMPATIBLE_API_KEY, or OPENAI_API_KEY, and a keyless gateway is fine (no Authorization header is sent). Model ids pass through untouched and are required (no default). A missing base URL or model fails fast with instructions instead of a curl error. Requested in cornball-ai/corteza#149.
agent()'s OpenAI-wire request now omits the Authorization header when no key is configured (matching chat()), so keyless gateways don't receive a bare "Bearer " header.

Show all changes in 0.1.9Hide the rest of the changes in 0.1.9

The endpoint/key options are renamed to llm.api_base and llm.api_key, matching the sibling API packages (tts.api_base, stt.api_base, xtx.api_base). llm_base() / llm_key() are unchanged. The pre-0.1.8.1 names (llm.api.api_base / llm.api.api_key) are still read as a fallback, with a one-time deprecation warning per session.

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("llm.api", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("cornball-ai/llm.api")

Development version from cornball-ai/llm.api. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-llm.api

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-llm.api

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-llm.api

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
