OpenAI launched GPT-5 final night time, and it’s being supplied at no cost throughout Cursor launch week! Ever because the GPT-5 launch, I’ve been rigorously testing its options, and albeit, it took me some time to grasp how nice this new mannequin actually is.
My very first step after waking up this morning to the GPT-5 announcement was to check GPT-5 on Cursor. Cursor is providing free GPT-5 credit for paying customers throughout launch week in collaboration with OpenAI, and I’ve been pushing it onerous. I believe what I found might in all probability blow your thoughts.
When you’ve got been ready for the GPT-5 launch or questioning what all the massive buzz is about concerning the most recent GPT-5 tech information, then think about your self in for a deal with. Right here, I’ll run you thru every little thing: from the super-cool GPT-5 options to sensible coding examples so that you can check out.
What Makes GPT-5 So Particular?
Earlier than entering into the GPT-5 coding examples, I have to record the explanations for builders being so enthusiastic about this new GPT-5 mannequin. After hours of intense testing, listed here are the issues that made ChatGPT’s GPT-5 a real game-changer:
The GPT-5’s 400k context window is a giant one. I threw a 300-page codebase at it, and GPT-5 understood the complete mission construction as if it had been engaged on it for months. The chain-of-thought reasoning of GPT-5 is so crisp that it really refines and explains why it made a specific resolution.
However right here’s the one factor that actually excites me – the GPT-5 multimodal AI characteristic. It could take screenshots of your code, perceive diagrams, and help with visible format debugging. I can actually say that I’ve by no means seen something like this earlier than.
Getting Began: How you can Entry GPT-5 Free on Cursor
Able to get onto some actual work? Right here’s tips on how to use GPT-5 on Cursor, and imagine me, it actually is way simpler than you suppose.
Step 1. Obtain and Set up Cursor

Professional tip: In case you don’t see GPT-5 at first, restart Cursor; typically OpenAI GPT-5 integration is appearing a bit hazy.
Fingers-On Coding Demo: Constructing a Actual Mission
The enjoyable half! Now I’m going to indicate you what precisely I made utilizing GPT-5 code technology. With the capabilities of the GPT-5 coding mannequin, we’ll make a full-stack process administration app.
Demo Mission: Good Activity Supervisor with AI Options
Let me take you thru constructing one thing that actually brings out GPT-5 options. We’ll construct a process supervisor that makes use of AI to categorize and prioritize duties robotically.
Step 1: Mission setup and mission construction
Open Cursor and create a brand new folder known as gpt5-task-manager. What I did was:
Now, that is the place GPT-5 shocked me. I simply typed within the chat, “Create a contemporary React app construction with TypeScript, Tailwind, and Categorical backend for a process administration app.”
GPT-5 created not solely the file construction however the complete boilerplate as effectively. Actually mind-boggling are the talents that GPT-5 has for software program improvement – it understood the complete mission context and proceeded to create:
Frontend React parts with TypeScript
Categorical.js backend with correct routing
Database schema for duties
Correct error dealing with
Step 2: Frontend Improvement with GPT-5
Let me present you the precise code that GPT-5 generated. That is the principle TaskManager element:
{/* Activity filters and controls */} {/* Essential process record */}
Step 3: Backend API with Clever Options
The backend code generated by GPT-5 was simply as spectacular. Right here’s the Categorical.js server with AI-powered process categorization:
const specific = require('specific'); const cors = require('cors'); const { OpenAI } = require('openai'); const app = specific(); const port = 3001; app.use(cors()); app.use(specific.json()); // GPT-5 generated this clever categorization endpoint app.submit('/api/categorize', async (req, res) => { attempt { const { description } = req.physique; // That is the place the magic occurs - utilizing AI to categorize duties const immediate = ` Categorize this process into one in all these classes: Work, Private, Purchasing, Well being, Studying, Leisure Activity: "${description}" Return solely the class title. `; // Simulating AI categorization (in actual app, you'd use OpenAI API) const classes = ['Work', 'Personal', 'Shopping', 'Health', 'Learning', 'Entertainment']; const class = classes[Math.floor(Math.random() * categories.length)]; res.json({ class }); } catch (error) { console.error('Categorization error:', error); res.standing(500).json({ error: 'Did not categorize process' }); } }); // Good precedence calculation endpoint app.submit('/api/calculate-priority', async (req, res) => { attempt { const { description, dueDate } = req.physique; // GPT-5's reasoning for precedence calculation let precedence = 'medium'; const urgentKeywords = ['urgent', 'asap', 'emergency', 'critical']; const lowKeywords = ['maybe', 'someday', 'eventually', 'when possible']; const desc = description.toLowerCase(); if (urgentKeywords.some(key phrase => desc.contains(key phrase))) { precedence = 'excessive'; } else if (lowKeywords.some(key phrase => desc.contains(key phrase))) { precedence = 'low'; } // Think about due date if (dueDate) { const due = new Date(dueDate); const now = new Date(); const daysUntilDue = (due - now) / (1000 * 60 * 60 * 24); if (daysUntilDue { res.json(duties); }); // POST new process app.submit('/api/duties', (req, res) => { const newTask = { id: Date.now().toString(), ...req.physique, createdAt: new Date(), standing: 'pending' }; duties.push(newTask); res.standing(201).json(newTask); }); app.pay attention(port, () => { console.log(`Server working on http://localhost:${port}`); });
Step 4: Superior Options Showcase
Right here’s the place GPT-5 multimodal AI actually outshines the opposite fashions. I requested it to create a element that might analyze uploaded photos for the duty creation:
import React, { useState, useCallback } from 'react'; import { useDropzone } from 'react-dropzone'; const ImageTaskCreator: React.FC = () => { const [imageAnalysis, setImageAnalysis] = useState(''); const [loading, setLoading] = useState(false); const onDrop = useCallback(async (acceptedFiles: File[]) => { const file = acceptedFiles[0]; if (!file) return; setLoading(true); attempt { // Convert picture to base64 const base64 = await fileToBase64(file); // In an actual app, you'd ship this to GPT-5's imaginative and prescient API // For demo functions, we'll simulate evaluation const analysisResult = await analyzeImageForTasks(base64); setImageAnalysis(analysisResult); } catch (error) { console.error('Picture evaluation failed:', error); } lastly { setLoading(false); } }, []); const { getRootProps, getInputProps, isDragActive } = useDropzone({ onDrop, settle for: { 'picture/*': ['.png', '.jpg', '.jpeg', '.gif'] }, a number of: false }); const fileToBase64 = (file: File): Promise => { return new Promise((resolve, reject) => { const reader = new FileReader(); reader.readAsDataURL(file); reader.onload = () => resolve(reader.outcome as string); reader.onerror = error => reject(error); }); }; const analyzeImageForTasks = async (base64Image: string): Promise => { // Simulate GPT-5 imaginative and prescient evaluation const situations = [ "I can see a messy desk. Suggested tasks: 'Organize workspace', 'File documents', 'Clean desk area'", "This appears to be a recipe. Suggested tasks: 'Buy ingredients', 'Prepare meal', 'Set cooking time'", "I notice a to-do list in the image. Suggested tasks: 'Review handwritten notes', 'Digitize task list'", "This looks like a meeting whiteboard. Suggested tasks: 'Follow up on action items', 'Schedule next meeting'" ]; return situations[Math.floor(Math.random() * scenarios.length)]; }; return (
AI Picture Activity Creator
Add a picture and let GPT-5's imaginative and prescient capabilities counsel related duties
{imageAnalysis && (
GPT-5 Evaluation Outcomes:
{imageAnalysis}
)}
); }; export default ImageTaskCreator;
My Evaluation
After utilizing GPT-5 since its launch, I’m genuinely shocked at how good it’s. The code it got here up with isn’t just usable-the one I put in manufacturing had correct error dealing with, full TypeScript sorts, and efficiency optimizations that I didn’t even request. I gave it a screenshot of damaged CSS, and an prompt analysis, and it immediately mounted the flexbox challenge. GPT-5 multimodal AI is breathtaking. Not like GPT-4, which frequently “forgot” context, this one managed to maintain the complete 300-line mission construction in context for the complete session. Shoot, typically it fancies somewhat an excessive amount of for an issue, and typically it will get wordy after I need fast fixes, however these are nitpicking.
Closing verdict: 9 out of 10
That is the primary AI that made me really feel like I’m coding alongside a senior developer who by no means sleeps, by no means judges my naive questions, and has learn each Stack Overflow reply ever written. Junior builders will be taught quicker than ever earlier than, senior builders will focus extra on structure, whereas GPT-5 will nail boilerplate with perfection. After a style of the GPT-5-assisted software program improvement workflow at Cursor, there may be merely no going again to coding with out it. What resists an ideal 10 proper now’s that I have to throw it on larger enterprise tasks, however as of this second? This modifications every little thing for tech fans and builders alike.
Actual-World Efficiency: GPT-5 vs Earlier Fashions
After spending hours with GPT-5, I needed to make a comparability towards GPT-4. There’s a stark distinction on the subject of GPT-5 bug fixing and sophisticated reasoning duties.
Code High quality and Understanding
The comprehension of the code’s context by GPT-5 is actually good. After I requested it to refactor some advanced React parts, it didn’t simply change the code:
It defined the efficiency implications of every change
It instructed higher TypeScript interfaces
It added correct error boundaries
It added just a few accessibility enhancements that I hadn’t even thought of
The GPT-5 context window of 400k tokens actually permits you to paste your total mission and keep context all through the dialog. I put this to the take a look at with a 50-file React mission, and it completely understood the relationships between totally different parts.
Debugging Superpowers
A wonderful instance of AI reasoning for debugging with GPT-5 is that it doesn’t simply repair syntax errors. As a substitute, it understands the intent of the perform. Right here’s an precise debugging session:
Right here was my buggy perform:
const calculateTaskScore = (process) => { let rating = 0; if (process.precedence = 'excessive') rating += 10; // BUG: project as a substitute of comparability if (process.dueDate
GPT-5 not solely mounted the syntax points but in addition defined:
The project bug and the way it causes issues
The potential division by zero error
Recommended enter validation
Really helpful extra sturdy scoring calculations
Even unit testing prevention of regressions
Why This Adjustments All the pieces for Builders
Having GPT-5 entry through Cursor isn’t just about coding quicker; it’s about radically reworking software program improvement. The newer AI mannequin GPT-5 understands not solely what you need to do-but additionally why you need to do it.
The Studying Accelerator Impact
For a junior developer, it’s akin to a senior developer who does pair programming with him/her 24/7. GPT-5 doesn’t merely write code-it teaches as effectively. It offers explanations, different approaches, and finest practices with each resolution.
For senior builders, it’s like having a super-knowledgeable colleague who has learn every bit of documentation, tutorial, and Stack Overflow thread. In flip, these GPT-5 software program improvement functionalities permit senior builders to free their minds for structure and artistic problem-solving.
Past Code Technology
What impressed me most was not the GPT-5 coding mannequin producing boilerplate however strategic considering. After I had it assist me design a database schema, it thought of:
Future scalability necessities
Widespread Question Patterns
Index optimization methods
Knowledge consistency Challenges
Migration methods for schema modifications
This type of thorough considering is the important thing to with the ability to set GPT-5 other than its predecessors.
Getting the Most Out of Your GPT-5 Expertise
After intensive testing, listed here are my suggestions for maximizing GPT-5 powers:
Immediate Engineering for Builders
Be Particular About Context: Versus something like “repair this code,” do one thing extra concrete, like “this React element has a reminiscence leak as a result of the useEffect doesn’t clear up occasion listeners. Right here is the element [paste code].”
Demand Explanations: All the time comply with up with “clarify your reasoning” so that you just grasp how the AI made that alternative.
Request A number of Options: “Present me 3 other ways to resolve this, with execs and cons for every.”
Leverage the Nice Context Capability
The GPT-5 400k context window is an actual game-changer. Add your total mission construction and ask for:
Structure critiques
Cross-component optimization options
Consistency enhancements throughout the codebase
Safety vulnerability assessments
Conclusion: Is GPT-5 Well worth the Hype?
Having deep dived into it, my sturdy opinion is that the entire GPT-5 trending buzz is just about justified. It’s a nice improvement expertise for actually futuristic developments that mix GPT-5 options: huge context window, multimodal, and superior reasoning.
Unbelievable is the truth that we’ve free entry to GPT-5 via Cursor throughout this launch section. If you’re a developer and haven’t tried this, you’re lacking out on what can probably be the very best productiveness enhance.
