Quick summary — Why this matters

ChatGPT 5.1 (aka GPT-5.1) is an incremental but important upgrade focused on faster answers for simple tasks and deeper, clearer reasoning for complex ones. OpenAI released updated variants (Instant and Thinking), improved code capabilities, and better tone/personalization options — so students, creators, and marketers can get smarter, warmer, and more useful AI responses.

What’s new in ChatGPT 5.1 

• Two response modes: Instant for quick replies and Thinking for tough problems. ChatGPT chooses the right mode automatically when you use the Auto setting. OpenAI Help Center+1
  
  

• Better instruction following & tone: Warmer, more personality options (preset styles you can pick). This means better friendly or professional tones on demand. The Verge+1
  
  

• Improved coding & larger context: GPT-5.1 handles bigger codebases and has specialized Codex variants for developers (faster, more efficient reasoning for code tasks). OpenAI+1
  
  

• Adaptive reasoning: The model spends more compute only when needed, reducing “made-up” facts and improving accuracy for tricky queries. OpenAI Help Center
  
  

• New tools / dev features: API updates for apply_patch, shell utilities and prompt caching — useful for automation and building agents. OpenAI
  
  

(Short note: new collaboration features, like group chats inside ChatGPT, were added to support multi-person workflows.) The Verge

How to give perfect prompts for ChatGPT 5.1

With GPT-5.1, prompt clarity helps the model pick Instant vs Thinking effectively. Use this 3-part formula every time:

1. Role + Goal — Start with who the model should be and what it must do.
   Example: You are an SEO tutor. Help me write a 700-word blog outline about AI in marketing.
   
   

2. Context + Constraints — Add context and limits (tone, word count, style, keywords).
   Example: Use simple Hindi-English (Hinglish) phrases, include 3 examples, and target beginners.
   
   

3. Output format — Say exactly how you want the result (bullet list, table, code, etc.).
   Example: Return: H2 headings with 3 bullets each and a CTA link at the end.
   
   

Prompt example for a Thinking task (complex):
You are an expert data scientist. Analyze dataset X (describe columns) and list 5 hypotheses, each with test steps and Python code snippets.

Prompt example for an Instant task (quick):
Summarize the key differences between SEO and SEM in 4 short bullets.

Pro tips & tricks for ChatGPT 5.1

• Use “Auto” mode so the system routes Instant or Thinking automatically — you’ll get speed when possible and depth when needed. OpenAI Help Center
  
  

• Chain prompts: Break big tasks into smaller ones (outline → expand → polish). GPT-5.1 is better at following stepwise instructions. OpenAI
  
  

• Set personality presets when you need brand tone consistency (Professional, Friendly, Candid, etc.). The Verge
  
  

• Verify facts: For important facts, ask GPT to “show sources” or use the browsing tool when available. GPT-5.1 reduces hallucinations but always double-check critical data. OpenAI Help Center
  
  

• Use expanded context for code: Paste multiple files or docs — GPT-5.1 handles longer context windows better than earlier models. OpenAI
