OpenAI has launched GPT-5, a brand new flagship AI mannequin that can energy the corporate’s subsequent era of ChatGPT.
GPT-5, which was launched Thursday, is OpenAI’s first “unified” AI mannequin and combines the reasoning skills of its o-series of fashions with the quick responses of its GPT sequence. The following-generation mannequin alerts a brand new period for ChatGPT — and its creator, OpenAI — pointing to OpenAI’s broader ambitions to develop AI methods which are extra like brokers than chatbots.
Whereas GPT-4 enabled AI chatbots to supply good responses on all kinds of questions, GPT-5 permits ChatGPT to finish all kinds of duties on behalf of customers — reminiscent of producing software program functions, navigating a person’s calendar, or creating analysis briefs.
With GPT-5, OpenAI has additionally sought to make ChatGPT easier to make use of. As a substitute of asking customers to decide on the suitable settings, GPT-5 comes geared up with a real-time router that decides find out how to provide the perfect reply, whether or not that’s responding to person questions rapidly or taking extra time to “assume” by way of solutions.

Throughout a briefing with reporters, OpenAI CEO Sam Altman claimed GPT-5 is “the perfect mannequin on the planet,” and stated it represented a “important step” alongside the corporate’s path to creating AI that may outperform people at most economically useful work — that’s, synthetic common intelligence (AGI).
“Having one thing like GPT-5 could be just about unimaginable at any earlier time in historical past,” stated Altman.
Beginning Thursday, GPT-5 shall be obtainable to all free customers of ChatGPT as their default mannequin. OpenAI’s VP of ChatGPT, Nick Turley, stated that is a part of the corporate’s effort to offer free customers entry to an AI reasoning mannequin for the primary time. (Beforehand, the corporate gated these extra superior fashions behind a paywall.)
“That is simply one of many ways in which I’m excited to reside the mission, ensuring that these things truly advantages individuals,” stated Turley on the choice, referencing OpenAI’s long-standing mission to distribute superior AI to as many individuals as doable.

The expectations are excessive for GPT-5, one among OpenAI’s most anticipated product launches since ChatGPT put the corporate on the map in 2022. Since then, ChatGPT has grown into one of many world’s hottest client merchandise, reaching greater than 700 million customers each week — practically 10% of the globe’s inhabitants, in keeping with the corporate.
Many see GPT-5 as a bellwether for AI progress broadly, and the mannequin’s reception by Silicon Valley might have profound implications for Massive Tech, Wall Avenue, and policymakers regulating expertise. These stakeholders are watching to see if GPT-5 gives a major leap in AI’s capabilities, very similar to its predecessor, GPT-4, which challenged expectations of what software program can do.
GPT-5 gives a slight edge on the competitors
OpenAI claims GPT-5 is state-of-the-art in a number of domains, barely edging out main AI fashions from Anthropic, Google DeepMind, and Elon Musk’s xAI on key benchmarks. Nonetheless, GPT-5 barely underperforms frontier AI fashions in different areas.
The corporate says GPT-5 gives frontier-level efficiency round coding; Altman stated the mannequin particularly excels at spinning up whole software program functions on demand, in what’s turn into referred to as “vibe coding.”
On SWE-bench Verified — a check of real-world coding duties pulled from GitHub — GPT-5 scores 74.9% on its first try. Meaning GPT-5 simply outperforms Anthropic’s newest Claude Opus 4.1 mannequin, which scored 74.5%, and Google DeepMind’s Gemini 2.5 Professional, which scored 59.6%.
On Humanity’s Final Examination — a troublesome check measuring AI mannequin efficiency throughout math, humanities, and the pure sciences — a model of GPT-5 with prolonged reasoning (GPT-5 Professional) scored 42% when utilizing instruments. That’s barely lower than xAI was capable of obtain with Grok 4 Heavy, which scored 44.4% on the check.

On GPQA Diamond — a check of PhD-level science questions — GPT-5 professional scored 89.4% on its first strive, outperforming Claude Opus 4.1, which scored 80.9%, and Grok 4 Heavy, which scored 88.9%.
OpenAI says GPT-5 is healthier for answering health-related questions. On a check measuring accuracy in AI mannequin responses round healthcare subjects, HealthBench Exhausting Hallucinations, OpenAI says GPT-5 (with pondering) hallucinates simply 1.6% of the time. That is far decrease than the corporate’s earlier GPT-4o and o3 fashions, which scored 12.9% and 15.8, respectively.
Whereas AI chatbots will not be medical professionals, tens of millions of persons are utilizing them for well being recommendation. In response to this phenomenon, the corporate says GPT-5 is extra proactive about flagging potential well being considerations, and serving to customers parse medical outcomes.
As well as, OpenAI says GPT-5 is healthier than different AI fashions on tougher to measure, subjective domains, reminiscent of artistic design and writing. Turley stated GPT-5 responds extra naturally and displays “higher style” than different AI fashions on artistic duties.
“The vibes of this mannequin are actually good,” stated Turley.
GPT-5 can be extra correct than OpenAI’s earlier fashions, and the corporate says it suffers far much less from hallucinations — the tendency for AI fashions to make up data — in comparison with its o-series fashions. Hallucinations appeared to be getting worse in OpenAI’s newest AI reasoning fashions, reminiscent of o3, and OpenAI beforehand stated it didn’t fairly perceive why it was taking place.
In responses to ChatGPT prompts, OpenAI discovered that GPT-5 (with pondering) hallucinates and responds with incorrect data 4.8% of the time. That’s a major discount from o3 and GPT-4o, which rating hallucination charges of twenty-two% and 20.6% on the check.
On a benchmark measuring an AI mannequin’s agentic skill to finish simulated on-line duties, Tau-bench, GPT-5 gives combined efficiency. On a part of check measuring an AI’s skill to navigate an airline web sites, GPT-5 scores 63.5% barely underperforming o3, which scored 64.8%. On one other a part of the check measuring AI’s skill to navigate retail web sites, GPT-5 scores 81.1%, underperforming Claude Opus 4.1, which scored 82.4%.
OpenAI additionally says that GPT-5 is safer than its earlier fashions. Whereas AI reasoning fashions sometimes exhibit an inclination to scheme towards people or lie to advertise their very own objectives, OpenAI discovered that GPT-5 was misleading at a decrease price than different fashions.
OpenAI security analysis lead Alex Beutel stated decreasing deception not solely improves the security of GPT-5, but additionally the person expertise, making a mannequin that’s extra “clear and sincere in methods customers can belief.”
Beutel additionally notes GPT-5 is healthier at discerning between dangerous actors which are making an attempt to misuse ChatGPT and customers making innocent requests. This ends in GPT-5 with the ability to refuse extra unsafe questions, whereas providing fewer rejections to customers searching for innocent data.
Upgrades for shoppers and builders
ChatGPT is getting a couple of person expertise upgrades as a part of the GPT-5 launch. Customers can now choose from 4 new personalities in ChatGPT’s setting: Cynic, Robotic, Listener, and Nerd. The corporate says these will adapt ChatGPT’s responses with out requiring customers to particularly ask the mannequin to reply in a sure manner.
Subscribers to ChatGPT’s $20-per-month Plus plan get greater utilization limits for GPT-5 than free customers. In the meantime, $200-per-month Professional subscribers may have limitless entry to GPT-5, as effectively a souped-up model referred to as GPT-5 Professional that makes use of extra computational assets to supply higher solutions. Organizations on OpenAI’s Staff, Edu, and Enterprise plans will achieve entry to GPT-5 as their default mannequin subsequent week.
For builders, GPT-5 is coming to OpenAI’s API in three sizes — gpt-5, gpt-5-mini, and gpt-5-nano — which is able to spend roughly time “reasoning” by way of duties. Builders also can now management verbosity within the OpenAI API, deciding how lengthy or brief an AI mannequin’s responses ought to be.
The bottom mannequin of GPT-5 will price builders $1.25 per million enter tokens (roughly 750,000 phrases, longer than all the Lord of The Rings sequence), and $10 per million output tokens.
The launch of GPT-5 comes after a busy week for OpenAI. The corporate launched an open-weight reasoning mannequin, gpt-oss, that builders and enterprises can obtain free of charge and a run at a fraction of the fee. The open mannequin practically matched the talents of OpenAI’s earlier high fashions, o3 and o4-mini, however GPT-5 units a brand new commonplace for frontier efficiency in some areas, reminiscent of coding.
Nonetheless, GPT-5 appears to be roughly on par with different frontier AI fashions in a number of areas. Benchmarks, in fact, solely inform a part of the story for any AI mannequin, and it stays to be seen how builders will use GPT-5 in the actual world, and whether or not the mannequin is really a step above the competitors.
