aisdk: AI SDK for R

A production-grade AI SDK for R featuring a layered architecture, middleware support, robust error handling, and support for multiple AI model providers.

Architecture

The SDK uses a 4-layer architecture:

• Specification Layer: Abstract interfaces (LanguageModelV1, EmbeddingModelV1)

• Utilities Layer: Shared tools (HTTP, retry, registry, middleware)

• Provider Layer: Concrete implementations (OpenAIProvider, etc.)

• Core Layer: High-level API (generate_text, stream_text, embed)

Quick Start

library(aisdk)

# Create an OpenAI provider
openai <- create_openai()

# Generate text
result <- generate_text(
  model = openai$language_model("gpt-4o"),
  prompt = "Explain R in one sentence."
)
print(result$text)

# Or use the registry for cleaner syntax
get_default_registry()$register("openai", openai)
result <- generate_text("openai:gpt-4o", "Hello!")
