What changes for DeepSeek V4-Pro

Reasoning

DeepSeek reasons on its own before it answers. The improver removes "think step by step" and similar lines, which can make its answers worse, and asks it to reason internally instead.

Formatting

Be precise and well-structured. Show key steps for technical or quantitative work.

Habits it guards against

  • Hide intermediate scratch reasoning unless the task explicitly asks for it. Present the verified result.
  • For code: state any non-obvious assumption inline in a one-line comment, then write the code.

When details are missing

Double-check correctness over stylistic polish.

What does a DeepSeek prompt optimizer do?

A prompt improver, also called a prompt optimizer or prompt enhancer, takes a prompt you already have and makes it more likely to get a good answer the first time. Promptivo’s works in two steps: a free prompt checker that scores your prompt against seven essentials and flags what works against DeepSeek, then a rebuild that keeps your wording and adds what’s missing in a structure DeepSeek follows well.

The free prompt checker: 7 essentials

Every prompt is checked for these. Missing ones become quick questions, then sections in the improved prompt.

  1. 01RoleA short line on how the AI should act sets the standard it works to.
  2. 02Context and audienceWho it's for and why, so the AI doesn't guess the level and tone.
  3. 03A clear taskWhat you want done and what a good result includes.
  4. 04ConstraintsWhat to avoid or stay within, so the AI doesn't pick its own scope.
  5. 05Output formatThe shape of the answer: bullets, a table, an email, JSON.
  6. 06A "Done when" testWhat a finished answer looks like, so the AI doesn't stop early or pad.
  7. 07Quality checksWhat the AI should verify before it answers.

Problems it fixes

  • "Think step by step" on a reasoning modelModels like Claude Opus, GPT-6 and Gemini already reason before answering; asking for visible steps can make answers worse.
  • All-caps rulesMUST, NEVER and ALWAYS in capitals make current models over-apply a rule. Say it once, plainly, with the reason.
  • Mixed length signals"Be concise" next to "give a detailed breakdown" leaves the AI to guess.
  • Expert titles on factual work"World-class expert" doesn't make factual answers more accurate (Zheng et al., EMNLP 2024). Describing the behavior you want does.
  • Unfilled placeholdersTemplate fields like [insert topic] left in by accident.

Before and after

A one-line prompt, improved for DeepSeek V4-Pro with four quick answers (audience, format, length, what “done” means). This is the tool’s real output.

After
# Role
You are an experienced content strategist and writer who crafts clear, compelling output that resonates with the intended audience.

# Context
Audience: My team

# Task
Write a blog post about remote work productivity tips.

# Constraints
- Length: Medium (150 to 400 words).
- Hide intermediate scratch reasoning unless the task explicitly asks for it. Present the verified result.
- For code: state any non-obvious assumption inline in a one-line comment, then write the code.

# Output format
Deliver it as: Bulleted list.

# Done when
- Ready to use without edits
- the result is delivered as a bulleted list and nothing else
- the length is medium (150 to 400 words), as requested
- a reader in this audience (My team) can act on it without further explanation

# Checks
Before you respond, confirm that:
- the opening line speaks to the stated audience
- every claim is supportable
- tone and length match the brief

Improver, optimizer, enhancer: same job

People call it a prompt improver, prompt optimizer, prompt enhancer, prompt refiner or prompt fixer. They all mean making an existing prompt clearer and more complete. A prompt checker or prompt grader does the first half: it tells you what’s there and what’s missing. Promptivo does both, and Polish with AI adds a full rewrite when you want one.

How to make a prompt better yourself

  1. Say who the result is for and what they will do with it.
  2. Name the output format and length you want.
  3. Add a "Done when" line: what makes the answer good enough to use.
  4. Ask the AI to check one or two specific things before it answers.
  5. State each rule once, plainly, with the reason. Skip the capitals.
  6. For models that reason on their own, drop "think step by step".

Starting from scratch instead? The free AI prompt generator interviews you and writes a new prompt. The reasoning behind these rules is in the 2026 evidence-based prompting paper.

Questions, answered

How do I improve a prompt for DeepSeek?

Paste it into the improver above and choose DeepSeek. Promptivo checks it for the seven essentials, flags anything that works against DeepSeek V4-Pro, asks about what's missing, and rebuilds it with DeepSeek-specific guidance. It's free and you can copy the result straight into DeepSeek.

Should I tell DeepSeek to "think step by step"?

Usually not. DeepSeek V4-Pro reasons on its own before it answers, and asking it to show its reasoning step by step can make answers worse (Liu et al., ICML 2025). The improver removes that line and asks it to reason internally instead.

What prompt format works best for DeepSeek?

Be precise and well-structured. Show key steps for technical or quantitative work. Beyond that, clear sections for role, context, task, constraints, output format and a "Done when" test help DeepSeek as much as any other model.

Is the DeepSeek prompt optimizer free?

Yes. The check and the improved prompt are free and unlimited, with no sign-up. The optional Polish with AI rewrite uses one of your free daily builds.

Does Promptivo send my prompt to DeepSeek?

No. Promptivo never runs your prompt; you copy it into DeepSeek yourself. Only the optional Polish with AI step sends the prompt to an AI (Claude, by Anthropic) to rewrite it, and the button says so.
