What stands out

What its maker marketed at launch, and what people found later, each with its source.

  • DeepSeek Sparse Attention (DSA)

    Introduced DSA (first in V3.2-Exp) to cut long-context attention compute while preserving quality.

    Source: huggingface.co

  • Hybrid thinking/non-thinking in one model

    deepseek-chat mapped to non-thinking mode and deepseek-reasoner to thinking mode of the same V3.2 weights.

    Source: api-docs.deepseek.com

  • V3.2-Speciale reasoning variant

    Separate high-compute Speciale variant served briefly on a temporary endpoint (no tool calls) until 2025-12-15; weights released.

Notes

API aliases deepseek-chat/deepseek-reasoner moved to V4-Flash on 2026-04-24 and were scheduled for discontinuation on 2026-07-24; V3.2 now only via open weights/third parties.
