This has been a memorable week for the open. On Tuesday, the models were seen in the release of a new Openweight Family of GPTOS. Midweek, the news broke that the company was talking to investors to sell potential stocks at a price of $ 500 billion. And now, one of the most expected releases that began just a few years ago after the LLM arms race … GPT5 is finally here.
GPT 5 is out today
The main event was today’s GPT5 release, the first flagship model of the Open after coming to GPT -4 March 2023. The GPT5 will be available to the GPT -Free, Plus, and team users, starting today, with enterprises and education rollout schedules for next week. In addition, the developers will have three API levels: GPT -5, GPT -5 Money, and GPT5 Nano.
The company began its launch by explaining the new design of the chatting logic. Previous chat GPT sessions have carried out users’ normal models and complex tasks to the company’s slow reasoning conditions. The GPT5 will remove this fork.
“So far, our customers have had to choose between standard GPT’s fast response or slower, more thoughtful response from standard GPT models, but GPT5 eliminates this choice, Openi Chief Research Officer Mark Chen said at the launch. The company explained that an internal controller now decides how long the model should think, which aims to provide the best response without extra delay in easy matters.

The benchmark slides at the event show scored 74.9 percent of the GPT5 on the SWE Bench, which measures Big Fixes in the coding projects. The model Aider scores 88 % on the polygroot coding test and the multi-modal MMMU sets a new height on the questioning suit. In 2025 Aime High School Mathematics Examination, the GPT-5 GPT-4O leads to an unknown margin. Open AI staff warned that formal assessments do not cover the issue of every real world use, but he also noted that high scores are compatible with internal observation benefits in reliable reliable.
The company said fraud and fraud during the training were major goals. Safety Lead Sachi Desai said that the GPT -5 shows less facts on internal tests and uses a safe completion method rather than a simple compliance or correction principle. Regarding fraud, Desai explained: “These are instances where the model can misrepresent the user’s actions or lie about the task success. Particularly it can happen when the work is identified, impossible, or lacking key tools. When an application is vague or potentially dangerous, such as instructions for lighting pyrozen fireworks, the model now offers partial guidance, indicates consumers to safety, and explains any refusal. The purpose of this change is to reduce the denial of the blanket, while prevention instructions that can cause damage.
The Open AIGPT 5 is also sending products and API updates built on 5, which includes more natural voice mode, new personal types, and memory that can connect Gmail and Google Calendar, and in addition to a step -by -step study mode for free users. For developers, GPT -5 adds custom tool calls that accept simple text, optional offerings, control a verb, and deepen trade for speed before using the device. The company claims that GPT5 has acquired 97 % on the Tao Square Benchmark for a multi -tool task, which is more than 49 % two months ago.
The launch of the GPT -5 has been very expected since the start of the GPT -4 in 2023. Although today’s rollout was confirmed free, Plus, and team users, and by 4:30 pm, GPT5 was not yet available for anything. A note on the website states, “GPT -5 Rollout: We are slowly rolling GPT5 to ensure stability during launch. Some users cannot still see GPT5 in our account because we increase the availability of stages.”
Sale of employees’ shares can value Openi about $ 500 billion
The news of the launch of the GPT5 with new reports about Openi’s diagnosis and capital plans, as well as news. Bloomberg reports that the company has about $ 500 billion in preliminary talks for secondary sale of shares of employees, including existing investors, including Trip Capital, buying purchases. If completed, the deal will increase the company’s paper price by about $ 300 billion in a $ 40 billion round led by the Soft Bank. Outlet states that Openi also earned $ 8.3 billion last week as the second installment of the finance round round. A secondary sale will give staff a liquidity and can help maintain severe talent competition with companies like Meta and Entropic.
Bloomberg also reported that Openi and Microsoft are rehabilitating their relationships, including access to Microsoft’s shares and open AI technology before the current contract expires in 2030. Microsoft enrolled in a long -term partnership with Openi in 2023, a restless management that proved to be rural, strategic and mutual dependence.
The open profit model is a hybrid, overseeing a profit -earning operating company with a non -profit parent company. The firm has discovered changes in the operating arm, including becoming a Public Benefit Corporation, while stating that non -profit monitoring will continue. Talks about structure and governance are underway with big investors. This debate is coming out in the midst of rapid growth: Openi said it expects Chat GPT to reach 700 million weekly active users this week, with more than 500 million in March.
New Open Weight Model: Is Openi alive in his name?
Another thing about Open AINews that will not be exempted this week is the release of a new Openweight Family of company models: GPTOS. The new models come in 20 billion and 120 billion parameter versions and are available on the faces and gut hubs that are found under Apache 2.0 license.
In a blog announcement, the company said, “These models improve similar open models on reasoning works, demonstrate strong tool use capabilities, and users improve for effective deployment on hardware. The latest internal models of Openi used to learn and use the techniques, and the techniques were used by other techniques.”
Both new models share a transformer architecture that takes advantage of a compound experiences to reduce the number of active parameters needed to take action on the input. The GPT -OSS -12.20B 5.1B parameters activates per token, while the GPT -OSS -20B activates 3.6B. The GPT -OSS -1220B is designed to operate in data centers and on high -end desktop and laptop computers, as it requires 80 GBGPUs to operate. The company says the smaller model, GPT -OSS -20B, can run on most consumer desktops and laptops, the company says, only 16 GB memory is needed, “it makes it ideal for local, or high -speed repetition without expensive infrastructure.” According to the Open note, the GPTOS-1220B model receives a close paralytity with Open AO 4-Meni on the basic reasoning benchmark, while the GPT-OSS-20B model offers similar results with the Open AO 3-mini on the ordinary benchmark.
Since GPTOS has open weight, or public downloadable parameters, researchers can only run models on their hardware instead of host API. This flexibility may be necessary for scientific use matters. Open weight models enable researchers to compare the results through benchmarks, while keeping their domain experiences, inspecting their results and methods, considering their domain data, and keeping the data private and low costs.
Through the GPT-OSS, users can expose the whole thinking thinking, adjust the depth of reasoning, and make each parameter fine. Models follow the instructions, call outdoor tools such as web search or web, and offer provision logs to help the audit results. Open says the purpose of this transparency is to accelerate reproductive research in areas such as molecular design and climate modeling.
Openi has taken the release of GPT-SOS a step forward for open weight models, citing reasoning and safety improvement, and noting how the GPTOS gives its host models more options for research and development how to finish its host model: “We use a healthy open-wearing and we use a healthy environment to help us access. Developers and researchers invite developers and researchers to invite developers and researchers.
