DeepSeek: DeepSeek V3.2 Exp

Implements DeepSeek Sparse Attention (DSA), a fine-grained sparse attention mechanism that selectively attends to relevant tokens rather than computing full quadratic attention across all positions. This reduces computational complexity from O(n²) to approximately O(n log n) while maintaining reasoning quality, enabling efficient processing of longer contexts without proportional memory overhead. The sparse pattern is learned during training and dynamically applied based on token importance scoring.

Maintains conversation state across multiple turns, tracking context, user intent, and reasoning chains within a single session. The model processes each turn by incorporating full conversation history, enabling coherent follow-up questions, clarifications, and iterative refinement of responses. State is managed client-side via message arrays passed to the API, with the model internally managing attention over the conversation history using the sparse attention mechanism.

Generates syntactically correct, executable code across multiple programming languages (Python, JavaScript, Java, C++, Go, Rust, etc.) with reasoning about algorithmic correctness, performance characteristics, and edge cases. The model applies sparse attention to understand full codebase context when provided, enabling generation of code that integrates with existing patterns. Outputs include inline comments, type hints, and error handling appropriate to the target language.

Performs step-by-step mathematical reasoning including algebraic manipulation, calculus, linear algebra, and logical proofs. The model generates intermediate reasoning steps (chain-of-thought), showing work for complex calculations and deriving conclusions from mathematical premises. Sparse attention enables tracking of long derivations by selectively attending to relevant prior steps rather than all previous tokens.

Synthesizes information from long documents or multiple sources into coherent summaries, key insights, and structured knowledge representations. The model uses sparse attention to identify and extract relevant information from lengthy inputs without processing every token equally, enabling efficient summarization of documents up to 100K+ tokens. Outputs include abstractive summaries, bullet-point key findings, and structured data extraction (tables, JSON).

Follows complex, multi-step instructions and decomposes ambiguous tasks into concrete subtasks with clear execution plans. The model interprets user intent from natural language instructions, identifies missing information, and generates step-by-step action plans. Sparse attention enables tracking of long instruction sequences by selectively attending to relevant prior steps and constraints.

Generates original creative content including stories, poetry, marketing copy, and dialogue with coherent narrative structure, character consistency, and stylistic variation. The model maintains narrative context across long passages using sparse attention, enabling generation of novel-length content without losing plot coherence. Outputs respect specified tone, genre, and structural constraints.

Translates text between 50+ languages with context-aware semantic accuracy, preserving tone, idioms, and cultural nuances. The model performs cross-lingual reasoning by understanding concepts across languages and generating responses in target languages. Sparse attention enables efficient processing of long multilingual documents by selectively attending to language-relevant tokens rather than processing all tokens equally.

Answers factual and analytical questions by retrieving relevant information from provided context or knowledge, generating responses grounded in evidence. The model identifies relevant passages from long documents using sparse attention, synthesizes information across multiple sources, and provides citations or evidence references. Responses include confidence levels and acknowledgment of information gaps.
