OpenAI has launched ChatGPT 5, making it the default model in ChatGPT and promising faster, more accurate answers.
Free users get default access within hourly message limits before the system switches to GPT-5 Mini. Plus and Pro subscribers enjoy higher limits and access to GPT-5 Pro and “Thinking” modes for more demanding work.
Team and Enterprise plans gain the highest capacity and performance options.
GPT‑5 is a unified system with a smart, efficient model that answers most questions, a deeper reasoning model (GPT‑5 thinking) for harder problems, and a real‑time router that quickly decides which to use based on conversation type, complexity, tool needs, and your explicit intent (for example, if you say “think hard about this” in the prompt).
The router is continuously trained on real signals, including when users switch models, preference rates for responses, and measured correctness, improving over time.
Once usage limits are reached, a mini version of each model handles remaining queries. In the near future, OpenAI plan to integrate these capabilities into a single model.
OpenAI state:
GPT‑5 not only outperforms previous models on benchmarks and answers questions more quickly, but—most importantly—is more useful for real-world queries.
We’ve made significant advances in reducing hallucinations, improving instruction following, and minimizing sycophancy, while leveling up GPT‑5’s performance in three of ChatGPT’s most common uses: writing, coding, and health.
By unifying its AI lineup into a single, adaptable system, OpenAI aims to simplify the ChatGPT experience and scale advanced reasoning for a global audience.
GPT-5’s success will depend on how well it balances speed, accuracy, and user trust—especially as AI competition intensifies.
