OpenAI launched ChatGPT Gov designed to provide U.S. government agencies an additional way to access the tech. In response to pressure from rivals like DeepSeek, OpenAI is changing the way its o3-mini model communicates its step-by-step “thought” process. The Responses API effectively replaces OpenAI’s Assistants API, which the company plans to discontinue in the first half of 2026. OpenAI introduced o3 in December, stating that the model could solve approximately 25% of questions on FrontierMath, a difficult math problem set. Epoch AI, the research institute behind FrontierMath, discovered that o3 achieved a score of approximately 10%, which was significantly lower than OpenAI’s top-reported score.
GPT-4, which was released on March 14, 2023, was made available via API and for premium ChatGPT users. Premium users were originally limited in the number of messages they could send to the new model, but OpenAI increased and eventually removed these limits. It allows users to send text messages, voice messages, and video messages, make voice and video calls, and share images, documents, user locations, and other content. In January 2018, WhatsApp released a standalone business app called WhatsApp Business which can communicate with the standard WhatsApp client. As of May 2025, the service had 3 billion monthly active users, making it the most used messenger app. Flex processing is available in beta on the o3 and o4-mini reasoning models for non-production tasks like model evaluations, data enrichment, and asynchronous workloads.

Although OpenAI notes it may not grant every request since it must balance privacy requests against freedom of expression “in accordance with applicable laws”. The chatbot uses GPT-4, a large language model that uses deep learning to produce human-like text. The feature will start rolling out to ChatGPT Plus, Team, and Pro users around the globe this week. OpenAI has begun testing a feature that lets new ChatGPT users sign up with only a phone number — no email required.

In October 2023 they also introduced passkey support, where a user can verify their login with on-device biometrics, rather than SMS. Visual effects also became available, adding visual filters to a user’s video feed. In December 2023, WhatsApp’s “View Once” feature expanded to include voice messages. In September 2017, WhatsApp’s co-founder Brian Acton left the company to start a nonprofit group, later revealed as the Signal Foundation, which developed the WhatsApp competitor Signal. Both airlines had previously launched customer services on the Facebook Messenger platform.
It can also critique the user’s writing, summarize long documents and translate text from one language to another. The paid version of ChatGPT also offers features like image and voice inputs and integrations with other OpenAI services like the image generator DALL-E. Many individuals use ChatGPT and comparable large language models (LLM) for mental health and emotional support. OpenAI acknowledged that there have been “instances where our 4o model fell short in recognizing signs of delusion or emotional dependency”, and reported that it is working to improve safety.

Google’s Bard launched on February 6, 2023, one day before Microsoft’s announcement of Bing Chat. The company announced a slew of generative AI-powered features to counter OpenAI and Microsoft. Despite this, users may “jailbreak” ChatGPT with prompt engineering techniques to bypass these restrictions. In 2025, OpenAI added several features to make ChatGPT more agentic (capable of autonomously performing longer tasks).
As of 2025, ChatGPT’s website is among the 5 most-visited websites globally, and has over 800 million active weekly users. ChatGPT is a generative artificial intelligence chatbot developed by OpenAI and released in November 2022. It currently uses GPT-5, a generative pre-trained transformer (GPT), to generate text, speech, and images in response to user prompts. In 2016, WhatsApp was accused of copying features from a then-unreleased version of iMessage. On June 13, 2013, WhatsApp announced that they had reached their new daily record by processing 27 billion messages. On May 9, 2014, the government of Iran announced that it had proposed to block the access to WhatsApp service to Iranian residents.

The company has mostly concentrated on challenges in rigid, predictable areas such as math and programming. OpenAI charges $150 for every million tokens (about 750,000 words) input into the model and $600 for every million tokens the model produces. OpenAI also said Mark Chen would step into the expanded role of chief research officer, and Julia Villagra will take on the role of chief people officer. The organization originally estimated that the best-performing configuration of o3 it tested, o3 high, would cost approximately $3,000 to address a single problem. The image generator was made available to all ChatGPT users on March 31, and went viral for being able to create Ghibli-style photos. OpenAI will discontinue its largest AI model, GPT-4.5, from its API even though it was just launched in late February.

When a user deletes media for everyone, WhatsApp does not Tuuri Kasino casino delete images saved in the iOS camera roll and so those users are able to keep the images. In February 2015, WhatsApp implemented voice calling, which helped WhatsApp to attract a different segment of the user population. On November 14, 2016, WhatsApp added video calling for users using Android, iPhone, and Windows Phone devices. In 2023, WhatsApp replaced the Electron-based apps with native versions for their respective platforms.
