Create DeepSeek Provider

Factory function to create a DeepSeek provider.

DeepSeek offers two main models:

• deepseek-chat: Standard chat model (DeepSeek-V3.2 non-thinking mode)

• deepseek-reasoner: Reasoning model with chain-of-thought (DeepSeek-V3.2 thinking mode)

Usage

create_deepseek(api_key = NULL, base_url = NULL, headers = NULL)

Arguments

api_key

DeepSeek API key. Defaults to DEEPSEEK_API_KEY env var.

base_url

Base URL. Defaults to "https://api.deepseek.com".

headers

Optional additional headers.

Value

A DeepSeekProvider object.

Examples

if (FALSE) { # \dontrun{
# Basic usage with deepseek-chat
deepseek <- create_deepseek()
model <- deepseek$language_model("deepseek-chat")
result <- generate_text(model, "Hello!")

# Using deepseek-reasoner for chain-of-thought reasoning
model_reasoner <- deepseek$language_model("deepseek-reasoner")
result <- model_reasoner$generate(
    messages = list(list(role = "user", content = "Solve: What is 15 * 23?")),
    max_tokens = 500
)
print(result$text) # Final answer
print(result$reasoning) # Chain-of-thought reasoning

# Streaming with reasoning
stream_text(model_reasoner, "Explain quantum entanglement step by step")
} # }
