OpenAI has begun rolling out GPT-5 across ChatGPT tiers, making the new large language model available to free, Plus, Pro and Team users now, with enterprise and education accounts slated to receive access within a week. The company says the model is available to about 700 million weekly users, but free access comes with capped usage. Paid tiers raise those limits; the article notes ChatGPT Plus and ChatGPT Pro subscribers receive higher or unlimited access and refers to those subscription fees using the placeholder ´? per month´ as presented.
The model is framed as an evolutionary step rather than a leap toward general intelligence. OpenAI emphasised a new ´reasoning model´ and a ´real router´ feature that automatically chooses which internal model to use based on the conversation and prompt complexity. That combination is designed to deliver stronger reasoning and fewer factual errors; OpenAI claims GPT-5 responses are roughly 45 per cent less likely to contain factual errors than GPT-4o. Still, the launch prompted mixed reaction: company demos highlighted PhD-level performance in coding and writing, while some experts cautioned that the update sustains momentum without resolving fundamental limits in current models.
Practical changes for users include better coding assistance, which OpenAI demonstrated by showing how GPT-5 can create interactive apps, websites and simple games from a prompt. ChatGPT powered by GPT-5 also introduces four preset personalities — ´cynic,´ ´robot,´ ´listener´ and ´nerd´ — to make conversations feel more natural and to reduce the ´sycophancy´ seen in prior models. Productivity integrations are expanded too; the chatbot can connect to Gmail and Google Calendar to surface scheduling help, reminders and email follow-ups, although those features will initially roll out to Pro users.
OpenAI highlights improvements on health-related answers, reporting higher HealthBench scores and more proactive, conversational behaviour, but the article reiterates that the chatbot is not a substitute for medical advice. The piece closes by stressing that GPT-5 is easier to use and offers tangible feature upgrades, yet it remains a step on a longer path toward any artificial general intelligence goal. For now, users should expect better reasoning and fewer hallucinations, plus expanded integrations and tiered access controls that steer heavier users toward paid plans.
