OpenAI has launched GPT-5, a brand new flagship AI mannequin that can energy the corporate’s subsequent technology of ChatGPT.
GPT-5, which was launched Thursday, is OpenAI’s first “unified” AI mannequin and combines the reasoning talents of its o-series of fashions with the quick responses of its GPT sequence. The following-generation mannequin indicators a brand new period for ChatGPT — and its creator, OpenAI — pointing to OpenAI’s broader ambitions to develop AI techniques which can be extra like brokers than chatbots.
Whereas GPT-4 enabled AI chatbots to supply sensible 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 best settings, GPT-5 comes outfitted with a real-time router that decides find out how to supply one of the best reply, whether or not that’s responding to person questions rapidly or taking further time to “suppose” by way of solutions.
Throughout a briefing with reporters, OpenAI CEO Sam Altman claimed GPT-5 is “one of the best mannequin on the earth,” and mentioned it represented a “vital step” alongside the corporate’s path to growing AI that may outperform people at most economically worthwhile work — that’s, synthetic common intelligence (AGI).
“Having one thing like GPT-5 can be just about unimaginable at any earlier time in historical past,” mentioned 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, mentioned that is a part of the corporate’s effort to provide 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 dwell the mission, ensuring that these items truly advantages folks,” mentioned Turley on the choice, referencing OpenAI’s long-standing mission to distribute superior AI to as many individuals as attainable.

The expectations are excessive for GPT-5, one in every of 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 — almost 10% of the globe’s inhabitants, based on 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 Road, and policymakers regulating expertise. These stakeholders are watching to see if GPT-5 provides a major bounce in AI’s capabilities, very like its predecessor, GPT-4, which challenged expectations of what software program can do.
GPT-5 provides 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. Nevertheless, GPT-5 barely underperforms frontier AI fashions in different areas.
The corporate says GPT-5 provides frontier-level efficiency round coding; Altman mentioned the mannequin particularly excels at spinning up complete software program functions on demand, in what’s develop into often called “vibe coding.”
On SWE-bench Verified — a take a look at 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 tough take a look at 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 take a look at.
On GPQA Diamond — a take a look at of PhD-level science questions — GPT-5 professional scored 89.4% on its first attempt, outperforming Claude Opus 4.1, which scored 80.9%, and Grok 4 Heavy, which scored 88.9%.
OpenAI says GPT-5 is best for answering health-related questions. On a take a look at measuring accuracy in AI mannequin responses round healthcare subjects, HealthBench Laborious 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 usually are not medical professionals, hundreds of thousands of individuals 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 best than different AI fashions on extra difficult-to-measure, subjective domains, reminiscent of inventive design and writing. Turley mentioned GPT-5 responds extra naturally and displays “higher style” than different AI fashions on inventive duties.
“The vibes of this mannequin are actually good,” mentioned 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 mentioned it didn’t fairly perceive why it was occurring.
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%, respectively, on the take a look at.
On a benchmark measuring an AI mannequin’s agentic capacity to finish simulated on-line duties, Tau-bench, GPT-5 provides blended efficiency. On a part of the take a look at measuring an AI’s capacity to navigate an airline’s web site, GPT-5 scores 63.5%, barely underperforming o3, which scored 64.8%. On one other a part of the take a look at measuring AI’s capacity 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 often exhibit an inclination to scheme towards people or lie to advertise their very own targets, OpenAI discovered that GPT-5 was misleading at a decrease price than different fashions.
Alex Beutel, OpenAI’s security analysis lead, mentioned decreasing deception improves not solely the protection of GPT-5, but in addition the person expertise, making a mannequin that’s extra “clear and sincere in methods customers can belief.”
Beutel additionally notes GPT-5 is best at discerning between unhealthy actors who’re attempting to misuse ChatGPT and customers making innocent requests. This ends in GPT-5 having the ability to refuse extra unsafe questions, whereas providing fewer rejections to customers in search of innocent data.
Upgrades for shoppers and builders
ChatGPT is getting just a few 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 approach.
Subscribers to ChatGPT’s $20-per-month Plus plan get larger utilization limits for GPT-5 than free customers. In the meantime, $200-per-month Professional subscribers could have limitless entry to GPT-5, in addition to a souped-up model referred to as GPT-5 Professional that makes use of further computational sources to supply higher solutions. Organizations on OpenAI’s Staff, Edu, and Enterprise plans will acquire 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 kind of time “reasoning” by way of duties. Builders may also now management verbosity within the OpenAI API, deciding how lengthy or quick an AI mannequin’s responses must be.
The bottom mannequin of GPT-5 will price builders $1.25 per million enter tokens (roughly 750,000 phrases, longer than the whole “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 at no cost and run at a fraction of the associated fee. The open mannequin almost matched the talents of OpenAI’s earlier high fashions, o3 and o4-mini, however GPT-5 units a brand new customary for frontier efficiency in some areas, reminiscent of coding.
Nevertheless, 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 true world, and whether or not the mannequin is actually a step above the competitors.
