DESCRIPTION

This module provides access to DeepSeek's models via their API.

Available Models (February 2026):

  • deepseek-chat - Fast, general-purpose chat model (default). Excellent for most tasks with strong multilingual support.

  • deepseek-reasoner - Advanced reasoning model with chain-of-thought capabilities. Best for complex problem-solving and logic tasks.

  • deepseek-v3.2 - Latest version with integrated thinking directly into tool-use. Supports tool-use in both thinking and non-thinking modes. Features updated chat template and "thinking with tools" capability.

Note: DeepSeek V4 is expected to launch mid-February 2026 with context windows exceeding 1 million tokens and enhanced codebase processing capabilities.

Dynamic Model Listing: DeepSeek inherits from Langertha::Engine::OpenAI, so it supports list_models() for dynamic model discovery. See Langertha::Engine::OpenAI for documentation on model listing and caching.

THIS API IS WORK IN PROGRESS
