I tried to Vibe code with Chat GPT 5 and one shot prompt Pacman as well as lovable powered by chat gpt

I'm going to cut to the chase before sharing all Chat GPT's new capabilities (provided by CHAT GPT 5 and how it compares to all the major models. Chat GPT 5 can do some basic vibe coding. I attempted to one shot prompt pacman with native chat gpt 5 free version.

I saw the chat bot spin up the code and the calculations. I asked it to process the code and it created a playable html version of the game that looked good. It didn't have sound effects and I couldn't get pacman to move. I would say for now that native chatgpt 5 is not read to challenge the vibe coding platforms like Bolt.new, replit, and lovable. I did find Lovable did a limited time integration with chat gpt 5 and so I attempted to build a quick pickleball booking portal. You can check the demo here. It didn't quite build what I wanted, but I was pretty general in my first prompt.

Honestly I'll need to do more testing on the paid versions of these platforms to truly explore any major benefits.

Introducing ChatGPT-5: What’s New and What Sets It Apart

A Smarter, Unified AI Experience

ChatGPT-5 marks a significant consolidation — replacing former models like GPT-4o, o3, and others with a single system that automatically decides when to deliver quick responses or deeper reasoning. Users can still manually choose from variants like GPT-5 Thinking or GPT-5 Pro for complex tasks (DataCamp, OpenAI).

Enhanced Reasoning & Factual Accuracy

• ChatGPT-5 is designed for stronger analytical abilities, providing more accurate responses up to 45% fewer factual errors than GPT-4o and 80% fewer in its deep-thinking mode (CBS News, The Times of India).

• The revamped model architecture allows it to “think more deeply” on tasks like coding, scientific queries, financial analysis, and writing (OpenAI Help Center, OpenAI, Exploding Topics).

Developer & Coding Powerhouse

• GPT-5 shines in complex, end-to-end coding tasks. It’s shown to generate polished, aesthetically pleasing front-end designs, complete games, and interactive web apps from a single prompt — impressively mindful of spacing, typography, and user experience (OpenAI, DataCamp).

Improved Personalization & UI Customization

• ChatGPT-5 introduces customizable personalities—Cynic, Robot, Listener, and Nerd—tailoring its tone to your preferences (The Indian Express, The Times of India).

• You can also customize the chat’s color theme, select voice tones, and personalize the interface more than before (OpenAI, DataCamp).

Productivity & Multimodal Enhancements

• Integration with Gmail and Google Calendar enables scheduling assistance, email drafting, and reminders (The Indian Express, DataCamp).

• GPT-5 supports multimodal inputs and offers different context windows depending on your subscription tier—ranging from 8K tokens for free users to a massive 128K tokens for Pro users (DataCamp, OpenAI).

Availability & Adoption

• GPT-5 is now rolling out to Free, Plus, Pro, and Team users, with Enterprise and Education tiers being phased in soon (OpenAI Help Center, The Indian Express).

• Microsoft has integrated GPT-5 into Copilot, Visual Studio, Microsoft 365, and Azure AI Foundry, leveraging its reasoning capabilities across enterprise, developer, and consumer products (Source).

Early Feedback & Challenges

• While GPT-5 has been praised for its intelligence and speed, some users reported that its personality felt “dimmer,” more technical, or less expressive than previous versions like GPT-4o (WIRED).

• In response, OpenAI CEO Sam Altman pledged to restore prior model options for Plus users, improve the routing system, and boost rate limits while continuing to refine the user experience (WIRED).

ChatGPT-5 vs. Other Major AI Models: A Comparative Look

Model / Platform	Strengths & New Features	Limitations & Feedback
ChatGPT-5 (OpenAI)	Unified model with deep reasoning, personalization, developer tools, multimodal input	Some users find it emotionally distant; rollout issues
GPT-4o (OpenAI)	Speed, multimodal abilities, expressive tone	Now deprecated in favor of GPT-5 for most users
Claude (Anthropic)	Strong reasoning and safer outputs (community feedback)	Not directly compared in most sources
Google AI / Gemini 2.5+	Integrated with search and overview tools	Less documented in recent releases

Reddit users have highlighted these user experience shifts:

“GPT-5 is about lowering costs for OpenAI, not pushing the boundaries…”“It’s literally a repainted 4o… Knowledge cutoff is 2024…” (Reddit)

Summary

ChatGPT-5 represents a leap forward in AI user experience — offering smarter, faster responses, rich personalization, powerful coding support, and seamless integration with productivity tools. Yet, it’s not without early growing pains—some user feedback reflects concerns about tone and flexibility. Despite this, with continuous updates and backing from Microsoft’s platforms, GPT-5 sets a high bar for modern AI assistants.

Interested in diving deeper into a specific feature or want a companion post comparing GPT-5 to Gemini or Claude in more detail?

Here’s what’s happening with Lovable.dev and its integration of GPT-5:

GPT-5 Meets Lovable: What’s New?

• Limited-time preview available Lovable recently rolled out GPT-5 integration for a short-term preview — until midnight PT on Tuesday, August 12, 2025 — inviting users to test AI-assisted app creation powered by the latest model.(Lovable)

• State-of-the-art coding horsepower Behind the scenes, GPT-5 brings serious improvements. OpenAI reports breakthrough performance on coding benchmarks—74.9 % on SWE-bench Verified and 88 % on Aider Polyglot—enabling more accurate, efficient, and contextually aware code generation.(OpenAI, AInvest)

• Empowered prompt-to-app workflowOn Lovable, GPT-5 lets users build entire software projects with a single natural-language prompt, streamlining the process from ideation to deployment.(AInvest)
  

What Devs Say — Real Feedback from the Community

From Reddit discussions:

“Lovable offers some very nice built-in integrations… set up your Supabase edge functions and publish your work without ever having to log into a cpanel...”“They also just announced that they are integrating with GPT-5 and releasing it for the weekend…”(Reddit)

These comments highlight Lovable’s seamless back-end setup—like Supabase integration and one-click deployment—and how GPT-5 is enhancing that experience.

Why This Matters for Vibe Coders

Lovable already epitomizes vibe coding—let’s build things by “vibe” (plain language prompts) instead of syntax. GPT-5 upgrades this experience with:

• Higher code quality, accuracy, and fewer mistakes thanks to superior reasoning and coding strength.

• Robust agentic behavior—intelligently chaining tasks, debugging, and adapting to tool APIs.(OpenAI, AInvest)

• A more collaborative AI that can explain steps, propose next actions, and align with developer intent.(OpenAI)

All that combines to make building with Lovable faster, smarter, and more creative.
