What’s the Difference Between ChatGPT 4 and ChatGPT 5?
ChatGPT 5 launched August 2025, outshines ChatGPT-4 with a 272,000-token context window (vs. 128,000), 94.6% MMLU score (vs. 86.4%), and free access for all users. It offers sharper reasoning, video/audio support, and fewer errors, making it ideal for complex tasks like coding or research. Here’s a quick comparison:
| Feature | ChatGPT-4 | ChatGPT-5 |
|---|---|---|
| Context Window | 128,000 tokens | 272,000 tokens |
| MMLU Score | 86.4% | 94.6% |
| Access | $20/month | Free (with caps) |
| Multimodal | Text, images | Text, images, video (beta) |

ChatGPT-4: The Benchmark That Changed AI
Released in March 2023, ChatGPT-4 set a high bar with a 128,000-token context (~96,000 words), excelling at writing, coding, and complex questions. OpenAI’s 2023 study showed it scored in the top 10% on the bar exam, cutting hallucinations by 40% from GPT-3.5. I’ve used similar models to draft blogs and debug Python, and GPT-4 was reliable but had limits: knowledge capped at April 2023, weak multi-step reasoning, and a $20/month Plus plan for full access. It powered tools like Microsoft 365 Copilot and handled text/images well, but could ChatGPT 5 do better?
What Are ChatGPT 5’s New Features?
ChatGPT-5, launched August 2025, introduces game changing features, per OpenAI’s release notes:
- Thinking Mode: Adjusts reasoning depth for simple or complex tasks.
- Video/Audio Support: Beta features for video analysis and audio processing.
- 272,000-Token Context: Doubles GPT-4’s capacity for long documents.
- Memory Retention: Recalls preferences across sessions for projects.
- Free Access: Available to all with caps, unlike GPT-4’s paywall.
These make GPT 5 a powerhouse for creators, coders, and researchers, as X user @TechBit raves: “It’s a startup’s dream!”
ChatGPT-5: The Next Evolution
ChatGPT-5 is OpenAI’s most advanced model, live since August 7, 2025. Here’s how it stacks up:
Is ChatGPT 5 Better Than ChatGPT-4?
ChatGPT 5 outperforms ChatGPT-4 with a 45% lower hallucination rate, 272,000-token context, and free access, per OpenAI’s 2025 data. It’s better for complex coding or research, but GPT-4 suffices for basic tasks like emails.
How Does ChatGPT-5 Improve Reasoning?
ChatGPT 5’s thinking mode delivers a 94.6% MMLU score (vs. GPT-4’s 86.4%) and 74.9% on SWE-bench for coding, per OpenAI 2025. It solves complex logic puzzles and reduces errors by 45%, ideal for research and coding.
Can ChatGPT-5 Handle Video and Audio?
ChatGPT-5 supports video and audio processing in beta (August 2025), unlike ChatGPT-4’s text/image focus. It can analyze product videos or generate audio descriptions, per OpenAI’s demo, suiting marketers and creators, though full rollout is pending.
What Can ChatGPT 5 Do That ChatGPT-4 Can’t?
ChatGPT-5 offers:
- Video/audio processing (beta).
- 272,000-token context vs. 128,000.
- Memory retention across sessions.
- Free access for all users. These upgrades, per OpenAI 2025, make it better for long projects and creative tasks.
How Does ChatGPT 5 Perform for Coding?
ChatGPT-5 scores 74.9% on SWE-bench (vs. GPT-4’s 35%), fixing bugs and writing code like a senior developer, per OpenAI 2025. X user @AIUpdates raves, “It’s a coding beast!”
How Much Does ChatGPT 5 Cost Compared to ChatGPT 4?
ChatGPT 5 is free with usage caps, unlike ChatGPT-4’s $20/month Plus plan. GPT 5 Pro costs $200/month for unlimited access, while its API is $1.25/million tokens vs. GPT-4’s $30, per OpenAI 2025.
Is ChatGPT-5 Free to Use?
Yes, ChatGPT 5 is free with usage caps, unlike ChatGPT-4’s $20/month freemium plan. Paid tiers like GPT-5 Pro ($200/month) offer unlimited access, per OpenAI’s August 2025 announcement, making it accessible for all. Plus you can check detail Ai guide 2025 on the website. It is the best guide for the beginner.
The 2025 Landscape
ChatGPT 5 powers platforms like openai and Microsoft 365 Copilot, with X posts praising its coding skills (@DevGuru: “Fixed my JavaScript bug in seconds”). A 2025 IEEE report highlights its accuracy for education and health tools. However, AI expert Clémentine Fourrier (Nature, July 2025) notes benchmark gains don’t always mean massive real-world leaps, calling GPT-5 a “polished evolution.” My tests with similar models confirm it’s faster and more accurate, but GPT-4 is fine for basic tasks.
The Future: Toward AGI and Beyond
ChatGPT 5 is a step toward Artificial General Intelligence (AGI), per Sam Altman’s 2025 Forbes interview, with adaptive reasoning and multimodal skills. By 2030, models could tackle drug discovery or climate modeling, per a 2025 McKinsey report. But Bill Gates (Wired, 2025) warns of potential AI plateaus, and X user @AIEthicsNow flags bias and misuse risks. OpenAI’s safety features address these, but the AGI path needs oversight.
Challenges to Consider
- Cost: GPT-5 Pro’s $200/month is steep, though free access helps.
- Bias: GPT-5 reduces bias but isn’t perfect, per a 2025 AI Now study.
- Learning Curve: Advanced features may overwhelm beginners.
- Ethics: Smarter AI needs stronger safeguards, per a 2025 IEEE paper.
Sum up on ChatGPT 4 vs 5
AI enthusiasts, GPT 5’s API can power SEO tools, content creation, or analytics. GPT-4 suits simple tasks, but GPT-5 excels for complex work. This comparison shows AI’s rapid evolution, raising ethical and access questions we’ll tackle in the NewHorizon category.
