Code Generation Constraints
Language version, framework, performance requirements, and forbidden patterns all belong in the prompt — not as follow-up corrections. Promptuner flags missing technical specs before you generate code you can't use.
DeepSeek Prompt Optimizer
Optimize DeepSeek Prompts for Code & Reasoning
DeepSeek is purpose-built for code and technical reasoning. To use it at full capacity, prompts need explicit constraint specs and clear reasoning instructions. Promptuner scores these in real-time inside chat.deepseek.com.

// Why it matters
Built for how you use DeepSeek
Activate Chain-of-Thought
DeepSeek-R1's extended reasoning produces better outputs when the prompt explicitly requests step-by-step thinking. Promptuner detects reasoning tasks and structures prompts to activate it.
Compress Context, Expand Constraints
Promptuner's refactor compresses over-explained background to essential facts and expands the constraint spec to cover language, version, dependencies, and output format.
