GPT-5 Limitations vs. GPT-4: Key Differences
GPT-5 Limits & Model Breakdown: A Deep Dive (android Authority)
Here’s a summary of the Android Authority article about GPT-5 limits and model differences:
Key Takeaways:
GPT-5 Rollout: GPT-5 launched with some initial issues, including the temporary removal of older GPT models from the chatgpt interface. Some older models have since been reinstated.
Limit Structure: The limit structure has evolved as launch.
Free Users: Limited to GPT-5 with a cap of 10 messages every 5 hours. no access to legacy models.
Plus Users: Access to GPT-5 Fast, GPT-5 thinking, and GPT-5 Thinking Mini. Limits are:
GPT-5 (Auto): Virtually unlimited, often defaults to Fast. Usage of other models doesn’t count against limits.
GPT-5 Fast (Mini): Virtually unlimited.
GPT-5 Thinking: 200 requests per day.
GPT-5 Thinking Mini: 2,800 requests per week. Pro Users: Have virtually unlimited access to most tiers of GPT-5.
Temporary Limit Changes: OpenAI has adjusted limits since launch,and these are subject to change. If a Plus user hits their limit, ChatGPT will revert to GPT-5 Fast.
GPT-5 vs. GPT-4 Limits (Plus Tier):
| Model | GPT-5 Limit | GPT-4 limit |
|————–|——————–|——————–|
| GPT-5 (Auto) | Virtually Unlimited| GPT-4o: 80 msg/3hr |
| GPT-5 Fast | Virtually Unlimited| GPT-4: 40 msg/3hr |
| GPT-5 Thinking| 200 requests/day | GPT-4.5: 50 msg/week|
| GPT-5 Thinking Mini| 2,800 requests/week| GPT-4.1: 80 msg/3hr|
| | | GPT-4.1 mini: Unlimited|
| | | 03: 100 msg/week |
| | | 04-mini-high: 100 msg/day|
| | | 04-mini: 300 msg/day|
GPT-5 Sub-Model Use Cases (Based on User Experience):
The article notes that OpenAI’s official descriptions of the sub-models are vague, but based on experience, here’s a general breakdown (the article is cut off before completing this list).
Overall:
GPT-5 offers a simpler limit structure than GPT-4, but it also removes some of the flexibility of switching between models to work around limits. The limits are generous for Plus and Pro subscribers, but free users are substantially restricted.The limits are also subject to change.
