— Together with advances in general reasoning, coding, and professional knowledge work, GPT‑5.4 enables more reliable agents, faster developer workflows, and higher-quality outputs across ChatGPT, the API, and Codex, OpenAI writes.
On hallucinations, it is 33% less likely to be wrong in its responses, and 18% less apt to have mistakes in replies compared to GPT‑5.2.

The official Codex app has finally arrived for Windows, almost a month to the day after first debuting on macOS.
It runs natively in the Windows Subsystem for Linux, and has integrated terminals for PowerShell, Command Prompt, and Git Bash.
It also has all the «regular» features the Mac version has — and is a fully integrated multi-agent coding environment.
The Windows app is also properly sandboxed, so you can block it from accessing files outside your working folder and «prevent outbound links» unless you approve it, writes OpenAI’s Andrew Ambrosino on x.com.
In addition, your session history is stored on your OpenAI account, making it possible to start coding on a Mac and finish it on Windows without losing work, Engadget notes.
The app is available today from the Microsoft Store.

The reason for this is straightforward, suspecting that Anthropic and OpenAI going public «later this year» will shutter the window to private equity deals.
The latest deal to fund OpenAI with $30 billion «might be the last time» to «invest in a consequential company like this,» Huang admits.
Nvidia has invested some $130 billion in OpenAI in two rounds, the recent straight up investment, and one circular deal where they paid $100 billion in return for OpenAI buying $100 billion in chips from them.
Likewise, Nvidia was an investor in a November funding round for Anthropic, buying $15 billion in shares from the company.

During an all-hands meeting at OpenAI on Tuesday, Sam Altman tried to clear the air on their recent Pentagon contract debacle — which has seen some twists and turns before landing on very clear language against use in mass surveillance.
Of note at the meeting, he said that OpenAI was considering a contract to deploy on NATO’s classified network, although he was confirmed to have misspoken by a spokesperson, saying the deal being considered was for the unclassified parts of the defense alliance.
Later on Wednesday, Reuters confirmed that such a deal is indeed under consideration, citing sources «familiar with the matter.»
While talking, he said, among other things, that the US military had been a «great benefit to all of humanity over the last 250 years,» The WSJ writes, and added that «Clearly, the military has done things that I extremely disagree with, and am sure will do more in the future.»

This has been solved by reducing unnecessary «dead ends,» caveats and «declarative formulations» in order to let the conversation flow more freely — solving one of many users’ major gripes with the current OpenAI models.
The model is also better at search, combining search responses with its own knowledge and reasoning. This should put results into context instead of just summarizing results.
Bu the real update with this model is bringing ChatGPT to a more natural style and tone with freely flowing conversation — which should be far less «cringe.»
OpenAI is promising less «Stop. Take a breath»-responses, or «I’m going to calm this down» kinds of outputs. It should also be better at creative writing.
GPT-5.3-instant is available today in the app (choose Instant in the model selector), API and web, and updates to Thinking and Pro are «coming soon.»

A concerted effort to ditch ChatGPT for Claude has emerged online, even affecting reddit fan forums r/ChatGPT, r/OpenAI and the broader r/Singularity, which on Sunday were brimming with posts about moving to Claude.
Top of the list
As a result, Anthropic’s chatbot has climbed to number one, top of the list for productivity apps in the App Store — beating out both OpenAI and Gemini. Last week, it was hovering around 50th.
At more than double the cost of last years record deal, the funding highly values OpenAI by investors, according to Reuters.
Amazon invested $50 billion, Nvidia put up $30 billion and SoftBank shelled out $30 billion, agreeing to a $840 billion valuation, the largest of any frontier AI lab by far.
«Strategic partnership» with Amazon
Amazon’s deal structure is slightly different, as it comes in the terms of a strategic partnership where OpenAI will receive $15 billion up front, and then qualify for the rest $35 billion «over the coming months.»
OpenAI has committed to using 2 gigawatts of capacity on AWS’ Trainium platform and will make their models available on Amazon’s services.
None of this is said to change OpenAI’s relationship with Microsoft, OpenAI says in a release.
At the same time, OpenAI’s Nick Turley says they have surpassed 900 million weekly users and has 50 million paying subscribers, up from roughly 800 million before.

The spat started when Anthropic refused new terms in their Pentagon contract, saying they would not use their AI for autonomous killing and mass surveillance.
In a stunning reversal, these safeguards are written into an agreement offered just hours later to OpenAI (see below).

The new ChatGPT Android app (v1.2026.055) mentions a new "Naughty chats" setting

According to ChatGPT watcher Tibor Blaho, adult mode is getting closer to going live, with «spicier, adult-themed language.»
The idea was to get age verification on ChatGPT sorted first, so teens could be protected from «sensitive content,» while the app would let «adults be adults.»
Verification was rolled out in January, and people have been asking when ChatGPT for adults would finally ship.
Now The Information (paywalled) is citing sources from an all hands meeting at OpenAI touting an early prototype of a smart speaker.

Ads from Expedia, Qualcomm, Best Buy, and Enterprise Mobility have started appearing in relation to ChatGPT queries, Adweek reports.
The «early tests» have been ongoing since February 9th, and OpenAI is asking advertisers to pay a $200,000 minimum to join in.
— We believe ads play an important role in continuing to support broad access to AI, Asad Awan, ads and monetization lead at OpenAI, tells Adweek in a statement.
— By working closely with partners in this pilot, we’re able to thoughtfully test new ad experiences, he continues.
The advertising intelligence platform Adthena ran a test on over 500 prompts in ChatGPT and found ad placements on only 0.8% of responses, according to Adweek.
Adthena also found ads were clearly labeled, sometimes triggering on the first prompt, that OpenAI is surpisingly focused on privacy and user control, and that the text format seemed familiar and trusted.

Anthropic CEO Dario Amedei and OpenAI CEO Sam Altman were, however, for some reason, placed right next to each other on stage — and the acrimonious rivals promptly refused the gesture.

That’s why OpenAI is now launching «an advanced, optional setting for higher risk users.»
The idea is to disable tools an adversary might use to «to exploit to exfiltrate sensitive data,» such as prompt injection attacks in files or on the web.
When using Lockdown Mode, web use is limited to cached content only, and no live network access is available outside of OpenAI’s «controlled network»
Most people will never need this feature, OpenAI says, but it might be useful for corporate execs, security teams, journalists and officials.
OpenAI is also launching an «Elevated Risk»-setting, that lets users fine-tune network access for Atlas and Codex.
Both features are coming to users «in the coming months.»

Anthropic won that battle, and saw a jump in daily active users of 11%, CNBC writes, quoting BNP Paribas. In comparison, ChatGPT jumped 2.7% and Gemini added 1.4%.
Anthropic also won the battle over social media engagement, with more positive posts (25.5%) after their ad was shown than OpenAI (16.3%) — even though OpenAI led with 25K posts to Anthropic’s 10K.
Measuring through Instagram, OpenAI’s ad scored a 44% positive sentiment from 3,829 engagements on its post, while Anthropic scored 41% on 3,738 mentions, far behind the likes of Pepsi’s 33K mentions.
