Introduction: What Is GPT-5?
When OpenAI released GPT-5 on August 8, 2025, AIPURE was instantly on it, eager to see if OpenAI’s claims are true.
Sam Altman, OpenAI’s CEO, called GPT-5 “the best model in the world” for coding and writing. It’s now available to everyone—free ChatGPT users, paid ChatGPT Plus and Pro subscribers, API developers, and even through Microsoft Azure and GitHub Copilot.
If you’re curious and want to know GPT-5, keep reading. AIPURE walks through its features, price, access, and—crucially—how it stacks up versus GPT-4 and GPT-3.

GPT-5 Features: What Makes GPT-5 Different
Switching between different GPT versions, AIPURE immediately recognized just how striking the differences were. Now let's look at what makes GPT-5 unique.
- Unified Model with “Think Hard” Mode: No more switching between different model types. GPT‑5 automatically routes your queries to its reasoning engine when things get complex, ensuring you always get the deepest possible answer without extra clicks.
- PhD-Level Expertise: Compared to GPT‑3’s “high school” knowledge and GPT‑4’s “college graduate” feel, GPT‑5 genuinely responds like a subject-matter expert, whether you’re asking about healthcare, coding, or niche industries.
- Multimodal Capabilities: Beyond text, GPT‑5 can understand and reason over images, code snippets, math problems, and even diagrams, making problem‑solving far more seamless.
- Faster and More Efficient: Significant speed boosts mean you get high‑quality answers quicker, even for multi‑step or advanced reasoning queries.
- Fewer Hallucinations & Safer Completions: GPT‑5 has been stress‑tested for over 5,000 hours to cut down on inaccuracies. It’s better at admitting “I don’t know” and delivers safe, high‑level completions when dealing with sensitive prompts.
- Built‑In Personalities and Customization: Users can now choose from personas like “Cynic,” “Nerd,” “Robot,” or “Listener,” plus customize conversation colors — a fun way to make ChatGPT more personal.
- Best‑in‑Class Coding Performance: GPT‑5 crushes coding benchmarks like SWE‑Bench and Polyglot, writing cleaner and more reliable code, and handling full multi‑file projects with ease.

GPT-5 Pricing Explained
OpenAI has priced GPT-5 aggressively to encourage more users to switch and experiment:
| Model | Input ($/1M tokens) | Output ($/1M tokens) |
| GPT-5 | $1.25 | $10.00 |
| GPT-5 Mini | $0.25 | $2.00 |
| GPT-5 Nano | $0.05 | $0.40 |
- Free ChatGPT users: Have access to GPT-5 within certain limits; if you exceed the cap, you’re routed to a “mini” version.
- Plus plan: $20/month, gives extended access, more file/image usage, and priority limits.
- Pro plan: $200/month, gives “unlimited” access at max compute/priority
Token caching (repeated input) can drop your costs by up to 90%—a nice touch for power users and devs.
Moving on, let’s see exactly how you can use GPT-5 yourself.
GPT-5 Access: How to Use GPT-5
Getting into GPT-5 is super easy, and you don’t have to be a tech wizard:
- ChatGPT Website: Log into your ChatGPT (free or paid) account—GPT-5 is the default model for most tasks.
- ChatGPT Desktop/Mobile Apps: GPT-5 is the go-to if you have the latest update.
- API Developers: Instantly access GPT-5, GPT-5 Mini, or Nano via the OpenAI API or through Microsoft Azure/GitHub Copilot.
- Limits: Free users have a prompt cap, after which responses may come from the faster, cheaper mini model. Plus and Pro users enjoy much higher usage limits.
- Features Like Personalities: Just open settings in ChatGPT and you’ll see the new personality and color options.
All in all, if you want to try GPT-5, you don’t need to do anything special—just log in and go.
🤔💭 You might wonder: With all these upgrades, is GPT-5 really better than what came before? Then take a look at GPT-5 vs. GPT-4 vs. GPT-3 following AIPURE.
GPT-5 VS GPT-4 VS GPT-3: GPT Models Comparison
Here’s what you get when you hop between GPT-3, GPT-4, and GPT-5 from a user’s perspective:
| Feature/Aspect | GPT-3 | GPT-4 (incl. 4o) | GPT-5 |
| Release Date | 2020-2021 | March & May 2023 (4o) | August 7, 2025 |
| Expertise | Feels like high-school | Feels like college grad | Feels like PhD/industry expert |
| Multimodal Input | Mostly text | Text, image, (4o: voice) | Text, image, planning, more seamless |
| Reasoning Ability | Limited | Improved, a bit clunky | Unified, seamless, adapts to task |
| Speed | Decent | Fast (4o even faster) | Fastest, even with deep tasks |
| Coding Quality | Basic | Good, but fumbles complex | Industry-best; near-pro quality |
| Safety/Hallucinations | Hallucinates a lot | Improved, but still tricky | Strongest safeguards, admits “I don’t know” |
| Personality/Customization | Static | Slightly tone-adaptable | Multiple preset personas; vivid styles |
| Pricing | Cheapest/free | Entry-level, scalable | Mid-priced, more efficient per output |
| Token Limits | Low | High (4o: 128k) | Highest yet: 272k input, 128k output |
| Best For | Brainstorming, drafts | General work, chat, coding | Professional tasks, accurate reasoning, advanced workflows |
- GPT-3 is fun for basic brainstorming but unreliable on anything nuanced.
- GPT-4 (especially 4o) lifted everything—especially for image and voice tasks—but could still stall on tricky, multi-step logic or big data.
- GPT-5 makes iterative thinking and sophisticated work chess-like. It’s fast, much better at understanding weird requests without “freaking out,” and honestly, once you try it for serious projects, you won’t want to go back.
Final Thoughts: Should You Switch to GPT-5?
If you’re on the fence: do it. GPT-5 is the first time an AI actually feels like a versatile expert and not just a fancy autocomplete. For students, programmers, creative pros, and everyday users alike, it’s a game-changer for code, content, search, learning, analysis, and even “chatty” tasks.
OpenAI nailed the upgrade: smarter, safer, more customizable, and—most importantly—less frustrating when you’re on a roll. The pricing is reasonable, and with free access to start, it’s easy to see what all the fuss is about.
😊AIPURE’s verdict: Once you use GPT-5 for serious work, going back is not an option.
