DeepSeek V3.2 Exp

A 671-billion-parameter mixture-of-experts language model with 37 billion activated parameters and a 163,840-token context window, released in late 2025 as an experimental variant of the V3.2 line.

Strengths

Handles long documents and extended context windows while maintaining reasonable inference speed through its sparse mixture-of-experts architecture.

Best for

Tasks requiring processing of extended input documents where the full 163K-token context is needed, such as multi-document analysis or long conversation threads.

Limitations

Superseded by DeepSeek V4 models released in April 2026, which offer frontier-class performance; V3.2 Exp is a prior-generation model positioned for cost-conscious users who need its specific context window rather than the latest capabilities.
