OpenAI to launch GPT-5, its most powerful model today: What to expect

ChatGPT

OpenAI appears to be gearing up to unveil GPT-5, its next major AI model, during a livestream event this Thursday at 10AM PT. The teaser—“LIVE5TREAM”—all but confirms it, swapping the “s” in “livestream” for a “5.” Recent posts from OpenAI execs have only added fuel to the fire: CEO Sam Altman shared a screenshot with “ChatGPT 5” in the corner, while the head of applied research said he was “excited to see how the public receives GPT-5!”

While OpenAI hasn’t revealed specifics, GPT-5 is widely expected to be a significant upgrade over GPT-4 and GPT-4o. Improvements could include better reasoning, longer context windows, fewer hallucinations, and improved reliability across domains like coding, maths, and scientific writing. Given OpenAI’s growing focus on AI agents, GPT-5 may also be more “tool-aware” and capable of complex multi-step tasks.

One major question is whether GPT-5 will be multimodal. While GPT-4o unified text, image, audio, and video processing in a single model, GPT-5 could push further by enabling more natural conversation and broader sensory input. Enhanced memory features may also be on the table, allowing it to retain context across sessions.

Another thing to watch: performance on benchmarks. OpenAI has been quiet about recent academic testing, but GPT-5 could signal a leap in AI capabilities across coding, language understanding, and decision-making.

Whether GPT-5 becomes available to free users or remains locked behind ChatGPT Plus or enterprise tiers is unclear. But with rivals like Anthropic, Meta, and Google also pushing their own flagship models, Thursday’s launch could reset expectations for what’s possible with AI—and raise the bar for what’s next.
