DeepSeek: deepseek-chat

deepseek-chat is a dynamic model alias for DeepSeek's official API. As of January 2026, it points to the DeepSeek-V3.2 flagship. Utilizing a 671B total parameter MoE architecture with 37B active parameters, it serves as a versatile powerhouse for general-purpose tasks. Unlike the reasoning-focused deepseek-reasoner, this model defaults to Non-Thinking mode to ensure ultra-low latency and high throughput. Powered by DeepSeek Sparse Attention (DSA), it supports an expanded 1.01 million token context window. It remains one of the world's most cost-effective production-grade APIs, excelling in multilingual conversation, creative writing, and high-concurrency applications.
