• Unified Smart System
  GPT-5 replaces older models (like 4o, o3, o4-mini, 4.1, 4.5) with a single, intelligent system that automatically adapts. It routes queries to the most suitable sub-model—be it the fast base, deeper “Thinking” mode, or a compact mini version. OpenAIAnalytics Vidhya
  
  
• Better Benchmarks & Capabilities
  
  
• Achieves state-of-the-art results across math, coding, multimodal understanding, health, and more.
  
  
• For example, 94.6% on AIME math without tools; phenomenal coding benchmarks like 74.9% on SWE-bench Verified and 88% on Aider Polyglot. OpenAIAnalytics Vidhya
  
  
• Reduces hallucination rate by ~45% over GPT-4o, and by ~80% in “Thinking” mode compared to o3. OpenAIAndroid CentralCinco Días
  
  
• Multimodal & Context Advancements
  GPT-5 handles images, video, and text more effectively and supports much larger contexts—up to 400,000 tokens via API, and 256,000 in ChatGPT. Cinco DíasOpenAI
  
  
• Better Real-World Performance
