Is ChatGPT Plus More Accurate? New GPT-5 Update Analysis

OpenAI launched its GPT-5 model in August 2025. This update brought major improvements to ChatGPT. Both free and paying users received access to the new technology. The key difference lies in how much they can use it.

Free users get limited interactions with the full GPT-5 model. After that, the system switches to a less powerful version. This change affects answer quality and depth. Paying subscribers enjoy consistent access to the most advanced features.

ChatGPT Free vs. Plus: Key Differences Explained

Free users receive 10 GPT-5 interactions every five hours. Once they exceed this limit, ChatGPT shifts to GPT-5 mini. This lighter model still functions but lacks full capabilities. It offers slower response times and more factual errors.

ChatGPT Plus subscribers get up to 160 exchanges every three hours. They maintain full access to GPT-5’s advanced reasoning. This includes better handling of complex instructions and reduced hallucinations. The model provides more natural, accurate responses throughout extended conversations.

Measuring GPT-5’s Accuracy Improvements

OpenAI claims GPT-5 shows significant accuracy gains. It produces about 45% fewer factual errors than GPT-4 for everyday queries. When using its “thinking” mode, error rates drop nearly 80% compared to earlier models. This mode allows deeper analysis for complex questions.

Independent testing confirms these improvements. Evaluations like LongFact and FactScore show fewer mistakes. GPT-5 generates approximately six times fewer incorrect responses. It demonstrates particular strength with detailed, multi-layered prompts. This makes Plus subscriptions valuable for professional use.

The latest GPT-5 update makes ChatGPT Plus substantially more accurate for heavy users. While free access provides a glimpse of this power, consistent reliability requires a subscription. For researchers, writers, and professionals, the investment clearly pays off in superior results.

The subscription currently costs $20 per month. This provides priority access to new features and the most powerful models. It includes significantly higher usage limits.

Can free users try GPT-5?

Yes, free users get limited access to GPT-5. They receive 10 interactions every five hours. After that, conversations continue with the GPT-5 mini model.

Is the thinking mode available to everyone?

No, the deep reasoning mode is part of the full GPT-5 experience. It automatically activates for complex questions. Free users on GPT-5 mini cannot access this feature.

How reliable are GPT-5’s answers?

GPT-5 shows major improvements in factuality. It makes far fewer errors than previous models. However, users should still verify critical information from primary sources.
