Most importantly, ChatGPT has significantly reduced making things up! First, GPT-5 performs better at reducing "hallucinations" (when the model generates inaccurate or false information), with a noticeably lower error rate than previous versions. To prevent misuse, GPT-5 has also implemented more detailed safety measures, providing reasonable answers based on the nature of questions rather than simply refusing or providing irrelevant information. For example, with the question below, ChatGPT 4o easily fabricates a non-existent Legion Go 2nd generation, complete with convincing release dates, specifications, and pricing, when in fact it hasn't been released. ChatGPT 5, however, provides very accurate information and clearly states when information, such as release dates, is unknown.

In other aspects, GPT-5 is more intelligent in handling problems, automatically adjusting its reasoning method based on task complexity, from quick answers to deep thinking, making the model more flexible. In practical applications, it excels in writing, programming, and medical fields. Particularly in code generation and frontend development, GPT-5 can help users easily create interactive websites or mini-games, increasing work efficiency. In writing, it's more natural, capable of generating human-like articles, reports, or poetry, and can even handle vague prompts to develop complete final products.

In the health field, GPT-5 provides more reliable performance, especially in medical Q&A systems where its accuracy has greatly improved. As mentioned in the introduction, it can help patients translate incomprehensible medical information into text that average people can understand. It can even recommend more suitable medical solutions for you.

For businesses and professional users, GPT-5 Pro offers stronger reasoning capabilities and lower error rates, suitable for handling complex tasks. Ultimately, GPT-5 provides multiple usage options: free users can access the basic version, while those needing more features and higher allowances can choose Plus or Pro versions. Overall, GPT-5 has shown significant improvements across multiple fields, making it a more intelligent, practical, and secure tool.

PS: When our tech editor personally asked ChatGPT-5 about its improvements, surprisingly, the first thing ChatGPT did was to search on Google 😂

ChatGPT 5 vs ChatGPT 4o self-comparison:

GPT-5's biggest improvements compared to 4o are in "smarter reasoning, stronger programming and tool use, and longer context," while 4o still has advantages in "real-time voice/low latency interaction."

Key differences at a glance:

• Overall intelligence & benchmark scores: GPT-5 sets new records on multiple benchmarks including mathematics, coding, and visual understanding (such as AIME 2025, MMMU, etc.), officially positioned as a "smarter, faster, more useful" default model.
• Greatly improved coding ability: On the real-world software engineering benchmark SWE-bench Verified, GPT-5 achieves 74.9%, while 4o was measured at approximately 33.2%. This is directly reflected in its ability to fix bugs, read large repositories, and complete end-to-end tasks.
• Better "agent/tool" execution: GPT-5 is better at strategically calling multiple tools (in parallel/series), maintaining stability and focus on longer tasks.
• "Built-in thinking" unified system: In ChatGPT, GPT-5 automatically routes between "fast model/deep thinking model": instant responses for simple questions, extended thinking for difficult problems, reducing irrelevant answers.
• Longer context: GPT-5 documentation notes a 400,000 context window (text+image input, text output), while 4o offers 128k. This provides more capability for long files/extended conversations.
• More stable, less "people-pleasing": The system card states that GPT-5 shows significantly reduced sycophancy compared to the latest 4o in internal testing.
• Upgraded multimodal understanding (image/video/spatial reasoning): GPT-5 is stronger on visual/video reasoning benchmarks, more accurate when reading images, charts, and diagrams.

Areas where 4o still has advantages:

Real-time voice/conversation latency: 4o has native voice capabilities with latency as low as ~232ms, averaging ~320ms, making it very suitable for "human-like" voice chats; meanwhile, GPT-5's API model currently doesn't directly support audio I/O (ChatGPT's internal voice experience will gradually incorporate this, but the developer side focuses primarily on text/images).
