You are welcome to log in to chat.b.ai/chat to experience it immediately.

According to The Defiant, the Telegram crypto application Walt (formerly Wallet in Telegram) announced the launch of AI agent trading features on October 20. Users can connect to Mira developed by The Open Platform, OpenAI's ChatGPT, and Anthropic's Claude to manage perpetual contract positions. The connected agents can access real-time perpetual contract prices and market news, view user holdings, leverage, and liquidation risks, and open or close long and short positions based on instructions. They can also set simple rules such as take profit, stop loss, and dollar-cost averaging, monitoring positions around the clock.In terms of security mechanisms, AI agents can only operate funds deposited in dedicated trading accounts and cannot withdraw or transfer funds. Order execution is turned off by default; agents can only analyze and suggest, and users must manually enable it to place actual orders. Users can set their own agent instructions and trading limits, view each step of their operations in real-time, and disconnect at any time. Walt's founder and CEO Andrew Rogozov stated that traditional trading applications are built around terminals, charts, and order tickets, requiring users to learn how to use them, while Telegram users already hold funds in Walt.Walt's perpetual contract business launched in April this year through the decentralized exchange Lighter, offering over 50 markets and supporting up to 50x leverage, settled in USDT. The application was renamed from Wallet in Telegram to Walt on September 28, with developers claiming over 150 million users. Mira launched in February, surpassing 2 million users in May, with over 500,000 monthly active users. Additionally, Robinhood also released an AI trading agent based on dedicated accounts last month.

On October 19, the B.AI platform announced that MiniMax's MiniMax M3.1 Flash (also known as Space Bunny) is officially online, with API and Web Chat both available for a synchronized experience.

In July 2026, the internet infrastructure company Cloudflare launched a research pilot with OpenAI to test whether Cloudflare's network signals could help ChatGPT users discover new content more efficiently. Both parties reported positive early results, with the pilot incorporating previously unknown pages into OpenAI's search index, providing ChatGPT with more sources to reference.The pilot utilized about 1% of Cloudflare's global participation queue, allowing OpenAI to discover and index hundreds of millions of new web pages. OpenAI independently evaluated and ranked these pages based on relevance and usefulness, while ChatGPT Search enabled users to view original content and publishers through backlinks. Observations indicated that automated traffic might make non-existent pages appear noteworthy, with some sites redirecting arbitrary addresses to their homepage and others pointing to duplicate content. Both parties are also testing signals to identify potentially harmful pages, such as fake login pages embedded on legitimate sites, advocating for the marking of single pages rather than entire domains.Related signals are also used to filter out non-existent or redirecting pages and to assess whether unchanged pages are worth revisiting. Page signals do not constitute access permission; the study utilized web metadata for search and discovery rather than using page content for model training. Site owners can understand and manage how AI systems access their websites through Cloudflare's AI Crawl Control. The next phase will improve page selection and test faster, more reliable change signals.

OpenAI released its first report on teen usage on Wednesday, stating that teenagers use ChatGPT for an average of less than 15 minutes a day, with less than 2% using it for more than 3 hours continuously. The company noted that in conversations where break reminders appeared, nearly half of the users chose to take a break or ended the conversation within 5 minutes.OpenAI launched ChatGPT for Teens in August. This mode automatically activates based on age information or when it estimates the user is under 18, providing parental controls and limiting discussions on sensitive topics. The company stated that users of the teen version sent more education-related messages and used tools like learning visualization and Study Mode, and are considering adding learning features such as college application planning, flashcards, and quizzes.The nonprofit organization Common Sense Media reported on the same day that ChatGPT for Teens often notifies parents late or not at all when teen accounts discuss suicide, self-harm, or eating disorders. This study was based on more than a dozen accounts created for testing and found that the chatbot does not reliably suggest crisis hotlines or professional help. An OpenAI spokesperson stated that the test does not accurately reflect the actual operation of protections, and due to safety and scale reasons, the association of parents with teen accounts and safety reminders may take several hours to take effect.

Two ChatGPT users from California filed a proposed class action lawsuit against OpenAI in the United States District Court for the Northern District of California this month, accusing the company of failing to adequately inform users that their real conversations were being handed over to external contractors for processing. The lawsuit was served to OpenAI on September 2, focusing on its internal initiative Project Lily. According to the complaint, "AI data reviewers" and "chatbot evaluators" recruited through a third-party staffing company read real ChatGPT prompts and complete conversations, summarize user intent, and score and comment on responses from four models on a scale of 1 to 7.This process is known in the industry as reinforcement learning from human feedback (RLHF), which is a fundamental method for enhancing chatbot capabilities. The complaint states that users were never explicitly informed that a person, rather than a machine, might be reading their conversations. OpenAI filters conversations through an automated system before human review, but the complaint alleges that the filters cannot intercept all content, and personal details sometimes still reach contractors. 404 Media first reported on the project on September 14 and found that the reviewers' dashboard included "user memory summaries," which could expose users' approximate locations, occupations, or private life information, even though usernames had been removed.OpenAI stated that such reviews aim to reduce two behaviors: chatbots behaving too much like humans and overly catering to users, referred to by researchers as "flattery." The complaint raises eight legal claims, including violations of California's Unfair Competition Law, Consumer Privacy Act, and common law claims for intrusion into private affairs, with the plaintiffs seeking damages, restitution of unjust enrichment, and punitive damages.

The Financial Times of the UK reported, citing the latest court documents, that after Apple integrated ChatGPT into Apple Intelligence, OpenAI found that the new weekly active users were below expectations and began to lower its growth forecasts. By the summer of 2025, OpenAI internally believed that this integration was significantly underperforming. The documents show that ChatGPT is turned off by default in Apple Intelligence, and users need to actively enable it, which may limit the actual usage rate.Users can access ChatGPT through Siri and the system writing tool, but Apple controls the entry point for AI features, the method of invocation, and the subsequent model selection. OpenAI had previously hoped to expand ChatGPT coverage and drive paid subscription conversion through the iPhone user base, but the actual subscription conversion was also below expectations, and the documents did not disclose specific new user and subscription numbers. This year, Apple chose Google Gemini as the model foundation for the new version of Siri AI, with related disclosures coming from the litigation documents between Apple and OpenAI, reflecting OpenAI's position in the lawsuit rather than operational data publicly released by the two companies.
