Everything About You Want to Know About GPT-5: Feature, Performance, Price, Reviews

GPT-5 is the newest step forward from OpenAI, and it feels like the biggest upgrade yet. As someone who has tested many large models, I can tell you this one is faster, more accurate, and more practical in daily use. You will see changes not only in how it writes or codes, but also in how it understands your intent. In this guide, we will explore the gpt5 features, check its real-world gpt5 performance, and talk about price, release date, and reviews.

GPT-5 is OpenAI's latest AI system and a big leap forward. It can handle simple questions fast and complex problems with deep reasoning. On August 7,2025, OpenAI officially announced the launch of openai gpt-5, bringing major improvements in coding, math, writing, health advice, and visual understanding. GPT-5 is now available for everyone: free users get basic access, Plus subscribers enjoy higher limits, and Pro users unlock GPT-5 pro, which offers even more detailed and thoughtful answers.

GPT-5 brings some big changes that make it smarter and more useful. It beats older models on speed, accuracy, and usefulness. Here are the main GPT-5 features you should know about.

1 Better Coding Skills

GPT-5 is the best coding model OpenAI has made so far. It writes clean, beautiful code for websites, apps, and games from just one prompt. It even understands design basics like spacing and typography better than before. If you want to build software faster, GPT-5 performance here really stands out.

2 Improved Writing Help

GPT-5 is a great writing partner. It can turn your rough ideas into clear, natural text. It handles tricky writing tasks well, like free verse poetry or long reports. You'll find it easier to draft emails, essays, or stories with GPT-5's help. This is a key GPT-5 feature for anyone who writes regularly.

3 Smarter Health Advice

GPT-5 performs better on health questions, scoring higher on HealthBench tests. It acts like a thoughtful helper, flagging concerns and asking good questions. While it's not a doctor, it can help you understand medical info better. This shows GPT-5's real-world usefulness beyond just coding and writing.

GPT-5 is much faster, more accurate, and makes fewer mistakes than GPT-4o. Especially in important areas like math, coding, and health advice. For most people, the official benchmarks can be hard to understand, so here's a simple way to look at it.

Math:

GPT-5 scored 94.6% on a tough math test called AIME 2025, which is like a college-level exam. That means it gets almost all questions right, without extra help. GPT-4o doesn't score nearly this high, so GPT-5's reasoning is much stronger.

Health:

In medical questions, GPT-5 is more careful. Its "hallucination rate" (when it makes things up) is only 1.6%, compared to 15.8% for GPT-4o. So it's much safer to rely on GPT-5 for health info, though it's still not a doctor. It also asks better questions and thinks harder before answering.

Coding:

When writing and editing code, GPT-5 is a big step ahead. It scored 74.9% accuracy on a real-world coding test called SWE-bench, which measures how well it handles tricky programming tasks. GPT-4o scored only 30.8%. This means GPT-5 can help you build and fix software much better.

In everyday use, these improvements mean GPT-5 gives you faster, clearer, and safer answers. It's like having a smarter assistant who double-checks to avoid mistakes.

At the GPT-5 launch, OpenAI released three variants: GPT-5, GPT-5 mini, and GPT-5 nano. Here's what the company says they're for — and how that matched my own testing.

• GPT-5 is aimed at complex reasoning, broad world knowledge, and multi-step or code-intensive tasks — in my testing, it consistently delivered the most accurate results for these scenarios.
• GPT-5 mini is designed to balance speed, cost, and capability by trading a bit of knowledge for faster responses — I found it handled most mid-complexity reasoning well and was fast enough for everyday use.
• GPT-5 nano focuses on ultra-low latency and high throughput for simple, well-defined tasks — in practice, it responded almost instantly and worked best for bulk processing, though it struggled with open-ended prompts.

If you're wondering how much GPT-5 costs, it's important to know there are two main ways to pay for it: subscription plans and text token cost (pay-as-you-go API usage). The subscription plans work like monthly memberships you buy on the ChatGPT website or app, while token cost applies when you call GPT-5 via OpenAI's API—often used by developers or businesses building apps.

Let me break down the key differences between these two payment types, so you can pick what fits you best:

So, if you're a casual user who just chats occasionally, a subscription could be simpler. But if you're building an app or need full control over prompts, API token-based billing might work better. Next, I'll explain the detailed price comparison between the two methods for you.

GPT-5 Subscription Plans and Prices:

Here's a quick look at the different ChatGPT subscription tiers and what they offer:

GPT-5 API Token Pricing:

When you use GPT-5 through API calls, you pay based on the number of tokens processed (both input and output). The prices per 1,000 tokens differ by model size:

Note

You can see how the smaller models cost much less per token, but they also have lower reasoning and capability, which might affect your use case.

What Does This Look Like for Typical Tasks?

To make this clearer, think about different common tasks and how many tokens they use:

Which Payment Option Is More Cost-Effective?

Here's a side-by-side comparison of API token costs vs subscription plans at different monthly usage levels (total tokens):

So, if you only chat a little, say under 30,000 tokens per month, paying by token via API can save you money. But if you use GPT-5 a lot, especially for long texts or continuous conversations, the Plus subscription pays off quickly.

For very heavy users, like people who run lots of long chats or need advanced features, Pro is worth it despite the higher price. And if you want full control over prompts or build apps, API billing is the flexible choice.

When GPT-5 reviews started rolling in from big media like WIRED, Business Insider, and The Washington Post, the overall tone was cautiously positive. These outlets see GPT-5 as a step forward in AI, making "software on demand" feel closer to real life. The technology feels smoother and more practical than before.

But, what about everyday users? I checked Reddit to see real feedback from people actually using GPT-5 chat. The comments were mixed. Many users say GPT-5 is easy to use and works well for common tasks. One Reddit user said, "Software on demand is starting to feel real". That shows how much the AI is improving.

However, some people felt the entry-level version of GPT-5 didn't make a big difference compared to past models. A few users shared that it sometimes struggles with complex questions or feels slower than expected.

Here are some real user impressions from Reddit:
