OpenAI launched GPT-5 final evening, and it’s being offered totally free 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 exhausting. I feel what I found may in all probability blow your thoughts.
If in case you have been ready for the GPT-5 launch or questioning what all the large 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 all the things: 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 stepping 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 your complete challenge 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 determination.
However right here’s the one factor that basically excites me – the GPT-5 multimodal AI function. It may possibly take screenshots of your code, perceive diagrams, and help with visible format debugging. I can truthfully say that I’ve by no means seen something like this earlier than.
Getting Began: The way to Entry GPT-5 Free on Cursor
Able to get onto some actual work? Right here’s the way to use GPT-5 on Cursor, and imagine me, it actually is way simpler than you assume.
Step 1. Obtain and Set up Cursor
First issues first, head over to cursor.so and obtain that editor. Consider it as VS Code with further AI goodies. Only a few clicks for set up:
Obtain Cursor in your working system
Set up it like all regular utility
As soon as put in, open it, and you will notice the smooth interface instantly
Step 2: Set Up Your GPT-5 Entry
That’s the place it will get fascinating. Throughout GPT-5 launch week, Cursor offered customers with free GPT-5 trial entry, and lots of customers are nonetheless getting free credit for Cursor GPT-5. Right here’s the way to set it up:
Open Cursor, press Ctrl+Shift+P (Cmd+Shift+P on Mac)
Kind Cursor: Signal In, and sign up together with your account
Go to Settings > AI Fashions
Choose GPT-5 within the dropdown menu
Professional tip: When you don’t see GPT-5 at first, restart Cursor; typically OpenAI GPT-5 integration is performing a bit hazy.
Arms-On Coding Demo: Constructing a Actual Mission
The enjoyable half! Now I’m going to point out you what precisely I made utilizing GPT-5 code era. With the capabilities of the GPT-5 coding mannequin, we’ll make a full-stack job administration app.
Demo Mission: Good Job Supervisor with AI Options
Let me take you thru constructing one thing that basically brings out GPT-5 options. We are going to construct a job supervisor that makes use of AI to categorize and prioritize duties routinely.
Step 1: Mission setup and challenge construction
Open Cursor and create a brand new folder referred to 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 job administration app.”
GPT-5 created not solely the file construction however your complete boilerplate as effectively. Actually mind-boggling are the talents that GPT-5 has for software program improvement – it understood your complete challenge 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 Growth with GPT-5
Let me present you the precise code that GPT-5 generated. That is the primary TaskManager part:
{/* Job filters and controls */}
{/* Primary job 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 job 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.publish('/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 job into one in every of these classes:
Work, Private, Buying, Well being, Studying, Leisure
Job: "${description}"
Return solely the class identify.
`;
// Simulating AI categorization (in actual app, you'd use OpenAI API)
const classes = ['Work', 'Personal', 'Shopping', 'Health', 'Learning', 'Entertainment'];
const class = classes[Math.floor(Math.random() * categories.length)];
res.json({ class });
} catch (error) {
console.error('Categorization error:', error);
res.standing(500).json({ error: 'Did not categorize job' });
}
});
// Good precedence calculation endpoint
app.publish('/api/calculate-priority', async (req, res) => {
attempt {
const { description, dueDate } = req.physique;
// GPT-5's reasoning for precedence calculation
let precedence = 'medium';
const urgentKeywords = ['urgent', 'asap', 'emergency', 'critical'];
const lowKeywords = ['maybe', 'someday', 'eventually', 'when possible'];
const desc = description.toLowerCase();
if (urgentKeywords.some(key phrase => desc.contains(key phrase))) {
precedence = 'excessive';
} else if (lowKeywords.some(key phrase => desc.contains(key phrase))) {
precedence = 'low';
}
// Take into account due date
if (dueDate) {
const due = new Date(dueDate);
const now = new Date();
const daysUntilDue = (due - now) / (1000 * 60 * 60 * 24);
if (daysUntilDue <= 1) precedence = 'excessive';
else if (daysUntilDue <= 3) precedence = 'medium';
}
res.json({ precedence });
} catch (error) {
console.error('Precedence calculation error:', error);
res.standing(500).json({ error: 'Did not calculate precedence' });
}
});
// GET all duties
app.get('/api/duties', (req, res) => {
res.json(duties);
});
// POST new job
app.publish('/api/duties', (req, res) => {
const newTask = {
id: Date.now().toString(),
...req.physique,
createdAt: new Date(),
standing: 'pending'
};
duties.push(newTask);
res.standing(201).json(newTask);
});
app.pay attention(port, () => {
console.log(`Server working on http://localhost:${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 part 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.consequence as string);
reader.onerror = error => reject(error);
});
};
const analyzeImageForTasks = async (base64Image: string): Promise => {
// Simulate GPT-5 imaginative and prescient evaluation
const eventualities = [
"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 eventualities[Math.floor(Math.random() * scenarios.length)];
};
return (
AI Picture Job 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 Overview
After utilizing GPT-5 since its launch, I’m genuinely shocked at how good it’s. The code it got here up with is not only usable-the one I put in manufacturing had correct error dealing with, full TypeScript varieties, and efficiency optimizations that I didn’t even request. I gave it a screenshot of damaged CSS, and an prompt analysis, and it immediately fastened the flexbox situation. GPT-5 multimodal AI is breathtaking. Not like GPT-4, which frequently “forgot” context, this one managed to maintain your complete 300-line challenge construction in context for your complete session. Shoot, typically it fancies just a little an excessive amount of for an issue, and typically it will get wordy once I need fast fixes, however these are nitpicking.
Ultimate 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 sooner 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’s merely no going again to coding with out it. What resists an ideal 10 proper now’s that I must throw it on larger enterprise initiatives, however as of this second? This adjustments all the things 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 with regards to GPT-5 bug fixing and complicated reasoning duties.
Code High quality and Understanding
The comprehension of the code’s context by GPT-5 is absolutely 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 enables you to paste your complete challenge and keep context all through the dialog. I put this to the take a look at with a 50-file React challenge, and it completely understood the relationships between completely 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 operate. Right here’s an precise debugging session:
Right here was my buggy operate:
const calculateTaskScore = (job) => {
let rating = 0;
if (job.precedence = 'excessive') rating += 10; // BUG: task as an alternative of comparability
if (job.dueDate < new Date()) rating += 5;
return rating / job.description.size; // BUG: potential division by zero
}
GPT-5 not solely fastened the syntax points but in addition defined:
The task bug and the way it causes issues
The potential division by zero error
Prompt enter validation
Beneficial extra strong scoring calculations
Even unit testing prevention of regressions
Why This Modifications The whole lot for Builders
Having GPT-5 entry by way of Cursor is not only about coding sooner; 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 gives explanations, different approaches, and greatest 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 enable senior builders to free their minds for structure and inventive problem-solving.
Past Code Technology
What impressed me most was not the GPT-5 coding mannequin producing boilerplate however strategic pondering. After I had it assist me design a database schema, it thought of:
Future scalability necessities
Frequent Question Patterns
Index optimization methods
Knowledge consistency Challenges
Migration methods for schema adjustments
This type of thorough pondering 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 in depth 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 part has a reminiscence leak as a result of the useEffect doesn’t clear up occasion listeners. Right here is the part [paste code].”
Demand Explanations: At all times comply with up with “clarify your reasoning” so that you simply grasp how the AI made that selection.
Request A number of Options: “Present me 3 alternative ways to unravel this, with professionals and cons for every.”
Leverage the Nice Context Capability
The GPT-5 400k context window is an actual game-changer. Add your complete challenge construction and ask for:
Structure evaluations
Cross-component optimization options
Consistency enhancements throughout the codebase
Safety vulnerability assessments
Conclusion: Is GPT-5 Definitely worth the Hype?
Having deep dived into it, my robust opinion is that the entire GPT-5 trending buzz is just about justified. It’s a nice improvement expertise for really futuristic developments that mix GPT-5 options: huge context window, multimodal, and superior reasoning.
Unbelievable is the truth that we have now free entry to GPT-5 via Cursor throughout this launch part. In case you are a developer and haven’t tried this, you might be lacking out on what can doubtlessly be the very best productiveness enhance.
