What makes GPT-5 different from previous models

Unlike previous iterations, GPT-5 represents a fundamental shift in how OpenAI structures its AI offerings. This new model is designed with the user in mind, bringing several groundbreaking improvements that set it apart from its predecessors, ensuring a more personalized and intuitive experience.

More intelligent routing with real-time model switching

At the core of GPT-5 lies an intelligent architecture that automatically determines which model to use for each query. Rather than requiring users to select between different models manually, GPT-5 employs a real-time router that instantly decides whether to use its quick-response model or engage the deeper “GPT-5 thinking” mode. 

This decision-making process takes into account the type of conversation, its complexity, tool requirements, and explicit user intent, such as when you include phrases like ‘think hard about this’ in your prompt. 

Furthermore, the router continually enhances its performance through training on real user signals, including model switches, response preferences, and measured correctness.

Improved instruction following and reduced hallucinations

Perhaps the most significant advancement in GPT-5 is its dramatically reduced tendency to hallucinate or generate incorrect information. With web search enabled on anonymized prompts representative of ChatGPT traffic, GPT -5’s responses are approximately 45% less likely to contain factual errors than GPT-4o. 

Moreover, when in thinking mode, GPT -5’s responses are around 80% less likely to contain factual errors compared to OpenAI o3. On open-ended fact-seeking prompts, GPT-5 thinking shows a remarkable six-fold reduction in hallucinations compared to o3. In real-world testing, OpenAI reduced deception rates from 4.8% on o3 to just 2.1% in reasoning responses.

Faster response time with deeper reasoning

Despite its enhanced reasoning capabilities, GPT-5 respects your time by achieving greater efficiency than previous models. It extracts more value from less thinking time, performing better than OpenAI o3 while using 50-80% fewer output tokens across various capabilities, including visual reasoning, agentic coding, and graduate-level scientific problem solving. 

GPT-5 also introduces a ‘minimal’ reasoning option, which significantly reduces processing time by turning off most reasoning functions, allowing tokens to stream back almost immediately. This enhanced efficiency means faster responses for simple queries while maintaining thorough analysis for complex problems.

Key capabilities of GPT-5 across domains

The expanded capabilities of GPT-5 stretch across multiple domains, showcasing remarkable improvements in specialized areas that previous models struggled with.

Writing: More expressive and structured outputs

GPT-5 stands as OpenAI’s most capable writing collaborator to date, handling structural ambiguity with newfound precision. The model excels at sustaining unrhymed iambic pentameter and free verse that flows naturally, combining respect for form with expressive clarity. 

Notably, it’s more adept at handling complex creative constraints, delivering work with more substantial emotional impact and more explicit imagery. This translates to better everyday writing assistance for reports, emails, and other professional communications.

Coding: Frontend generation and debugging at scale

In the coding realm, GPT-5 sets new records with a 74.9% score on SWE-bench Verified and 88% on Aider polyglot. These benchmarks represent real-world software engineering challenges and code editing tasks, respectively. 

The model excels particularly in frontend development, creating responsive websites and applications with an intuitive sense for aesthetics. During internal testing, GPT-5 was preferred over its predecessor in frontend web development 70% of the time. It works best with specific frameworks like Next.js, React, and styling tools such as Tailwind CSS.

Health: Context-aware and safer health responses

For health-related queries, GPT-5 outperforms all previous OpenAI models on HealthBench evaluations. On the challenging HealthBench Hard subset, it scored 46.2%, a substantial improvement from the prior model’s 31.6%. 

The model functions as an “active thought partner,” proactively flagging concerns and asking clarifying questions based on user context. Nevertheless, OpenAI emphasizes that ChatGPT doesn’t replace medical professionals.

Math and science: Better problem-solving with logic

GPT-5 demonstrates exceptional mathematical reasoning, scoring 94.6% on AIME 2025 without tools. Interestingly, GPT-5 Pro with Python tools achieved a perfect 100% accuracy on this benchmark. For PhD-level scientific questions on the GPQA Diamond benchmark, GPT-5 Pro scored an impressive 89.4%. Essentially, the model’s enhanced reasoning capabilities make it perform like “a team of experts on call”.

How GPT-5 improves user experience

GPT-5 takes human-computer interaction to new heights, creating an experience that feels remarkably personalized and intuitive.

More human-like interactions

With GPT-5, OpenAI has significantly reduced the “talking to AI” feeling that plagued earlier models. The latest version is noticeably less effusively agreeable, uses fewer unnecessary emojis, and offers more thoughtful follow-ups that resemble conversations with a knowledgeable friend. Consequently, OpenAI has cut sycophantic (overly agreeable) responses from 14.5% to less than 6% in targeted evaluations. This balance creates more authentic exchanges without sacrificing helpfulness.

Custom personalities and tone control

For the first time, ChatGPT now offers four distinct personalities that users can select based on their preferences or specific tasks:

• Cynic: Provides sarcastic, dry humour with blunt, practical answers
• Robot: Delivers precise, efficient responses without emotional fluff
• Listener: Offers warm, reflective guidance with calm clarity
• Nerd: Explains concepts with enthusiasm while celebrating knowledge

These personalities, initially available for text chats and later for Voice mode, can be adjusted anytime through settings.

Better handling of ambiguous or complex prompts

GPT-5 excels at processing nuanced requests, demonstrating substantial improvements in following multi-step instructions and coordinating across different tools. Similarly, it’s more adept at reasoning through complex questions and maintaining context in extended conversations. Henceforth, when faced with potentially problematic queries, instead of refusing outright, GPT-5 attempts to provide the best safe answer possible.
