15 Prompting Secrets to Get More from ChatGPT-5

ChatGPT-5 is not GPT-4 with a minor upgrade. It represents a fundamental shift in how AI processes your requests, and if you are still prompting it the way you did six months ago, you are leaving serious capability on the table.

Since its August 2025 launch, ChatGPT-5 has delivered unprecedented performance across mathematics, coding, and reasoning tasks. The model achieved over 94% accuracy on advanced mathematics competitions and 74.9% on real-world coding benchmarks. Yet most Australian businesses are not seeing these results because they have not adapted their prompting strategies to match the model's new architecture.

The problem is not the AI. It is how you are talking to it.

Understanding ChatGPT-5's Invisible Router

Here is what changed that nobody tells you about. ChatGPT-5 uses an invisible router that automatically selects which model variant handles your request. If your prompt appears simple or vague, the router defaults to faster, less powerful processing to conserve computing resources. This means lower-quality responses, not because the capability is not there, but because your prompt did not trigger the advanced reasoning you needed.

This router determines whether your query gets handled by the instant model for quick responses or the thinking model for deep reasoning. Understanding this mechanism is the first secret to better results.

1. Be Ruthlessly Specific About Your Desired Outcome

Vague requests produce vague results. ChatGPT-5's router interprets ambiguity as simplicity, routing your query to basic processing.

Instead of "Write something about our new product," try "Write a 300-word product announcement for LinkedIn targeting Australian marketing managers aged 35 to 50, emphasising time savings and ROI. Use a professional but approachable tone and include a clear call to action."

The specificity signals complexity to the router whilst giving the model clear parameters for success.

2. Structure Complex Prompts with XML Tags

Using XML tags to organise different components of your prompt is highly effective for GPT-5's precision requirements. Rather than presenting walls of text, you explicitly label each element.

Structure your prompts like this:

<TASK>
Analyse this customer feedback and identify the top three pain points.
</TASK>

<FEEDBACK>
[Insert customer comments here]
</FEEDBACK>

<OUTPUT_FORMAT>
Present findings as a bullet list with supporting quotes.
</OUTPUT_FORMAT>

This structured approach helps ChatGPT-5 parse your requirements accurately, particularly for complex multi-part requests.

3. Leverage Chain-of-Thought Reasoning

Chain-of-thought prompting enables complex reasoning capabilities through intermediate reasoning steps. Instead of asking for immediate answers, you instruct the model to show its working.

Add phrases like "Let's think step by step" or "Explain your reasoning process" to prompts requiring analysis, calculation, or logical deduction. This technique forces the model into deeper processing mode, activating its advanced reasoning capabilities.

For strategic planning, competitive analysis, or complex problem solving, chain-of-thought prompting dramatically improves output quality. The model breaks down problems into manageable components, reducing errors and improving logical consistency.

4. Assign Expert Roles for Focused Responses

Role assignment shapes how ChatGPT-5 approaches your task. Tell the model exactly whose perspective and expertise you need.

"Act as an experienced email marketing strategist with 15 years in B2B SaaS" produces fundamentally different outputs than a generic request. The role assignment activates specific knowledge domains and communication styles.

For Australian businesses, be explicit about local context. "Act as a Sydney-based marketing consultant familiar with Australian Privacy Principles and local consumer behaviour" ensures outputs align with your regulatory environment and market conditions.

5. Provide Examples of What You Want

Few-shot prompting works brilliantly with ChatGPT-5. Show the model examples of your desired output format, tone, or structure before asking it to create something new.

If you want social media posts in your brand voice, provide two or three examples from your best-performing content. The model learns the pattern and replicates it with remarkable consistency.

This approach is particularly powerful for maintaining brand consistency across content creation, ensuring every output matches your established style.

6. Set Clear Constraints and Boundaries

What you exclude matters as much as what you include. Tell ChatGPT-5 explicitly what to avoid.

"Do not use marketing jargon or buzzwords. Avoid passive voice. Never exceed 150 words per section" gives the model firm boundaries. These negative instructions prevent common AI writing problems like overly promotional language or verbose explanations.

For Australian businesses, specify regional requirements. "Use Australian English spelling and reference ACCC guidelines where relevant" ensures outputs meet local standards.

7. Use the Meta-Prompt Technique

You can use a meta-prompt directly in ChatGPT-5 to have it optimise your initial prompt. This is prompting about prompting.

Ask ChatGPT-5: "I want to create a prompt that will generate high-quality email sequences for abandoned cart recovery. Review my initial prompt and suggest improvements for clarity, specificity, and effectiveness."

The model restructures your prompt using best practices, often revealing gaps in your original request you had not considered.

8. Demand Internal Quality Checks

Force ChatGPT-5 to self-evaluate before presenting final outputs. Add this universal prompt: "Before you respond, create an internal rubric for what defines a world-class answer to my request, then internally iterate on your work until it scores 10 out of 10 against that rubric".

This instruction triggers multiple internal revision cycles. The model generates output, evaluates it against quality criteria, revises, and repeats until meeting its own high standards. The result is dramatically improved quality without additional prompting from you.

9. Exploit the Extended Context Window

ChatGPT-5 offers up to 400,000 tokens of context memory, allowing you to include massive amounts of reference material in single prompts.

Upload your entire brand guidelines document, product specifications, and competitor analysis simultaneously. Ask ChatGPT-5 to cross-reference all three when creating marketing materials. The model maintains coherence across enormous context spans, something previous versions could not manage.

For Australian businesses, this means including your complete style guide, compliance requirements, and market research in one prompt, ensuring every output aligns with all your parameters.

10. Iterate Within Conversations, Not Across Them

ChatGPT-5 maintains conversation context brilliantly. Rather than starting fresh prompts for revisions, build iteratively within the same conversation thread.

After receiving initial output, respond with "Good start. Now make it more conversational and add specific examples from Australian retail." The model adjusts whilst retaining everything from previous exchanges.

This conversational refinement produces better results than trying to craft the perfect single prompt. Think dialogue, not dictation.

11. Specify Your Audience Explicitly

Who will read this output? ChatGPT-5 adjusts complexity, terminology, and examples based on your specified audience.

"Write this for C-suite executives with limited technical knowledge" produces drastically different content than "Write this for junior developers." The model calibrates explanation depth, jargon usage, and assumed background knowledge accordingly.

For Australian businesses targeting specific demographics, include relevant details. "Target Brisbane small business owners aged 45 to 60 without university degrees" helps ChatGPT-5 select appropriate language and references.

12. Request Multiple Options for Better Selection

Rather than accepting the first output, ask for variations. "Provide three different approaches to this email subject line, ranging from conservative to bold."

ChatGPT-5 generates diverse options, giving you genuine choice. This technique is particularly valuable for creative work where personal preference matters. You select the direction that resonates, then refine from there.

13. Use Temperature Control Through Language

Whilst you cannot directly adjust temperature settings in the ChatGPT interface, you can influence output randomness through prompt language.

For factual, consistent outputs, use phrases like "Provide the definitive answer" or "Give me the standard approach." For creative exploration, try "Brainstorm unexpected angles" or "Think outside conventional wisdom."

The model interprets these cues as implicit temperature adjustments, balancing creativity against reliability based on your indicated preference.

14. Combine Multiple Techniques for Complex Tasks

The most powerful prompts stack several techniques together. For a complex marketing strategy prompt, you might combine role assignment, XML structure, chain-of-thought reasoning, examples, constraints, and audience specification.

This layered approach works because each technique addresses different aspects of output quality. Role assignment shapes perspective, structure organises complexity, chain-of-thought improves reasoning, examples provide patterns, constraints prevent errors, and audience targeting ensures relevance.

These tips are not mutually exclusive and can be stacked on top of each other for even better results.

15. Give ChatGPT-5 Permission to Ask Questions

End complex prompts with "If you need any clarification or additional information to provide the best possible response, ask me before proceeding."

This invitation transforms the interaction from one-way instruction to collaborative problem solving. ChatGPT-5 identifies gaps in your requirements, potential ambiguities, or missing context that would improve final output quality.

For strategic business applications, this dialogue approach prevents wasted effort on outputs that miss the mark because of unstated assumptions.

The Reality About ChatGPT-5 and Australian Business

Effective prompt engineering has become a systematic method for producing precise and trustworthy results from large language models. As these systems advance, the best prompt engineers are moving beyond simple phrasing to apply structure, logic, and reasoning scaffolds.

For Australian businesses, this matters because ChatGPT-5 is not a magic solution that automatically understands your needs. It is a remarkably capable tool that responds to how well you communicate requirements. The difference between disappointing results and genuinely useful outputs usually comes down to prompt quality, not model limitations.

Your competitors are learning these techniques. Marketing teams at forward-thinking Australian companies are already using structured prompting to generate months of content in hours, analyse customer feedback at scale, and develop strategic plans with AI assistance. The competitive advantage goes to businesses that master the communication layer between human intent and AI capability.

Common Mistakes That Kill Your Results

Even with these secrets, certain mistakes will sabotage your ChatGPT-5 outputs. Avoid these traps:

Being too polite or conversational undermines clarity. ChatGPT-5 does not need social niceties. It needs precise instructions.

Asking for too much in a single prompt creates confusion. Break complex projects into sequential prompts, building on previous outputs.

Failing to verify factual claims remains crucial. ChatGPT-5 is significantly less likely to hallucinate than previous models, with responses containing approximately 45% fewer factual errors than GPT-4o. However, "less likely" does not mean "never." Always verify important facts, particularly for business-critical decisions.

Ignoring the context window limits creates problems. Whilst 400,000 tokens is massive, it is not infinite. Monitor token usage for extremely long conversations.

Implementing These Secrets in Your Workflow

Knowledge means nothing without implementation. Here is how to actually use these techniques:

Start with one technique per week. Master XML structuring first, then add chain-of-thought reasoning, then role assignment. Gradual adoption beats overwhelming yourself with fifteen simultaneous changes.

Create a prompt library for your common tasks. When you craft a particularly effective prompt for email marketing, save it. Build templates for recurring needs like social media content, customer responses, or strategic analysis.

Best practices for prompt engineering suggest an iterative approach. Start with an initial prompt, review the response, and refine based on output quality. Each interaction teaches you how the model responds to different instruction types.

Track what works for your specific use cases. A prompt structure that works brilliantly for content creation might fail for data analysis. Experiment systematically and document your findings.

Share successful prompts with your team. When someone discovers a particularly effective approach for your industry or business type, distribute it company-wide. Collective learning accelerates everyone's results.

The Future of Prompting is Already Here

ChatGPT-5 represents where AI is heading. Future models will be even more capable, even more nuanced, and even more demanding of quality prompts. The prompting techniques that work in 2026 focus on clarity, controlled output, and repeatable success.

Australian businesses that invest time now in mastering prompt engineering build a competitive moat. This skill transfers across AI models and platforms. The fundamentals of clear communication, structured thinking, and iterative refinement apply whether you are using ChatGPT, Claude, Gemini, or whatever emerges next.

The businesses winning with AI are not those with the most expensive subscriptions or the latest tools. They are the ones who understand how to extract maximum value from the capabilities already available. That comes down to communication skill, not technology access.
