Description

Creates a dynamic wrapper around existing model classes (OpenAI, Anthropic) based on user-provided configuration. The returned provider can be registered in the global ProviderRegistry.

Usage

create_custom_provider(
  provider_name,
  base_url,
  api_key = NULL,
  api_format = c("chat_completions", "responses", "anthropic_messages"),
  use_max_completion_tokens = FALSE
)

Value

A custom provider object with a language_model(model_id) method.

Arguments

provider_name

The identifier name for this custom provider (e.g. "my_custom_openai_proxy").

base_url

The base URL for the API endpoint.

api_key

The API key for authentication. If NULL, defaults to checking environmental variables.

api_format

The underlying API format to use. Supports "chat_completions" (OpenAI default), "responses" (OpenAI Responses API), and "anthropic_messages" (Anthropic Messages API).

use_max_completion_tokens

A boolean flag. If TRUE, injects the is_reasoning_model capability to ensure the model uses max_completion_tokens instead of max_tokens.
