What is GPT-5?
How does GPT-5 work?
- Intelligent Routing: When a user submits a prompt (text, image, or voice), the system’s router evaluates the request. Simple queries are handled by a fast, efficient model (like GPT-5 Nano or Mini) for quick responses, while complex, multi-step problems are automatically escalated to the deeper, more resource-intensive GPT-5 or Pro models. This ensures an optimal balance of speed, cost, and accuracy without the user needing to manually select a model.
- Enhanced Reasoning: The core of GPT-5’s advancement is its improved “thinking” capability, or Test-Time Compute (TTC). For harder problems, the model is allocated more computational power and explicitly breaks down the task, checks its own logic, and explores multiple reasoning paths simultaneously before merging the best results into a final, highly refined answer. This is an integrated Chain-of-Thought (CoT) process, which significantly reduces factual errors and boosts performance on complex logic puzzles and PhD-level science questions.
- Multimodal Integration: GPT-5 can seamlessly process and interrelate different data types, like analyzing a financial chart image and then generating a textual report. The model’s architecture integrates these inputs directly, allowing for a unified understanding and generation process.
- Agentic Workflows: GPT-5 is trained for agentic applications, meaning it can autonomously plan and execute a series of actions (like using various software tools, debugging code, or browsing the web) to achieve an end goal. It can provide user-visible “preamble” messages to communicate its plan and progress, making the execution transparent and auditable.
- Massive Context Window: The model has a substantial context length (up to 400,000 tokens), enabling it to process entire codebases, large datasets, or extensive documents in a single interaction, allowing for deeper context-aware decisions and improved instruction following.
How to use GPT-5?
Step-by-Step Guide to Using GPT-5
Step 1: Access the Platform
Go to the official OpenAI website (chat.openai.com) and sign up for an account. You can choose a free plan to start, which provides significant access to GPT-5’s core features. Once registered and logged in, you will be in the main chat interface.
Step 2: Enter Your Prompt
In the text box at the bottom of the screen, type your request, known as a “prompt”.
- For simple tasks (e.g., “Write an email announcing a team meeting”), be direct. The AI’s internal router will use a fast, efficient model (like GPT-5 Nano) to give you a quick answer.
- For complex tasks (e.g., “Analyze this dataset and provide a 5-page report”), provide detailed instructions and context. The system will automatically switch to a more powerful model (like GPT-5 Thinking or Pro) and dedicate more computational effort to solving it accurately.
Step 3: Leverage Multimodal Inputs
You are not limited to text. You can upload images, code snippets, or other files.
- Example: Upload a picture of a flowchart and ask, “Explain this workflow step-by-step.”
- Example: Paste a block of code and ask, “Find the bug in this Python script and explain the fix.”
Step 4: Refine and Iterate
The first answer is a starting point. If you want a different style, more detail, or a different format (like a table or a bulleted list), simply ask in a follow-up message. The model remembers the entire conversation context, so you can refine the output iteratively.
Step 5: Utilize Advanced Features (Optional)
For specific needs, you can explore settings to:
- Adjust tone and style: Ask it to “Respond as a formal business analyst” or “Keep it concise and friendly”.
- Enable Agentic Workflows: For complex, multi-step projects, GPT-5 can plan and execute a series of actions (e.g., “Research top marketing trends, draft a social media campaign, and schedule the posts”).
