CraftPrompts

DeepSeek prompt generator

Prompts for DeepSeek’s chat and reasoning models. Reasoning models think before they answer, so give them a clear goal and the facts they need, and skip step-by-step scaffolding.

  • Clear task verb missingStart with an explicit action: “Write…”, “Summarize…”, “Compare…”.
  • Background or context missingSay who it is for and why you need it; models fill gaps with generic guesses.
  • Role or perspective missingGive a perspective: “You are a senior UX writer…”. It sets vocabulary and depth.
  • Output format stated missingName the shape of the answer: table, bullets, JSON, 3 paragraphs.
  • Length or scope limit missingCap the length: “under 150 words”, “5 bullets”.
  • Constraints or rules missingAdd rules: what to avoid, what must be included, reading level.
  • Example or reference missingShow one example of the output you want. Few-shot beats description.
  • Specific, not vague missingReplace vague words (good, nice, interesting) with concrete criteria.

Prompting DeepSeek well

Keep reasoning-model prompts direct

DeepSeek’s reasoning models work through problems on their own. State the goal, the facts and the expected output format; long “think step by step” instructions add little.

Put everything in the user message

DeepSeek’s guidance for its R1 reasoning model recommended placing instructions in the user prompt rather than a system prompt. The generator’s single-message output suits this.

Ask for a checkable final answer

For maths or code, ask for the final answer in a fixed format (e.g. “Final answer: …”) so it is easy to verify.

New to structured prompts? The prompt engineering guide explains each part, and the prompt optimizer scores any prompt you already have.

Questions

How should I prompt DeepSeek R1 or other reasoning models?

Be direct: describe the problem, give the necessary context and say how you want the answer formatted. Avoid few-shot examples and heavy step-by-step instructions, which DeepSeek reported can reduce reasoning-model performance.

Does a DeepSeek prompt differ from a ChatGPT prompt?

For chat models, barely. For reasoning models, keep prompts shorter and more goal-focused, and let the model plan its own steps.

Is this tool affiliated with DeepSeek?

No. CraftPrompts is an independent, free prompt studio that works with any model.
