Conway Research launches local AI assistant Underdog with backing led by a16z

Conway Research has introduced Underdog, a personal AI assistant designed to run locally, and said it has raised backing from a16z, Khosla Ventures and other investors. a16z has confirmed that it led Conway Research’s seed financing round. The product currently runs directly on Mac, connects to a user’s email and calendar, and handles tasks such as finding emails, organizing schedules and managing day-to-day work. Because the model runs on-device, personal data does not need to be sent to a cloud AI service, and the assistant can still work offline. Conway Research said the public Woof model has 4 billion parameters, with 4-bit weights of about 2.37 GB. The team also built a Husky inference engine optimized for Woof and Apple Silicon. In company testing on an M5 Max, the same model ran faster than MLX across 16 tasks, with peak performance reaching 4.5x. Founder Sigil Wen said many routine jobs do not require the strongest model in a data center every time, and added that Underdog is planned for iPhone, Windows, Linux, Android and NVIDIA devices.

ByteDance’s personal AI assistant is reportedly named Xiaodou, with a standalone app planned

BlockBeats reported in a brief update that Doubao’s in-development personal AI assistant is internally positioned under the name Xiaodou and is expected to launch as a standalone app. The report said the project was not started as a last-minute response after Muse gained traction, noting that the Xiaodou name had already been decided this summer. The personal assistant effort, codenamed Spell, began internal testing in April and was initially led by the Doubao mobile assistant team. More recently, the project has been integrated more closely with Doubao’s existing product lineup and is now being handled jointly by the Spell project team and the Doubao chat team. Under the current product split, Doubao’s main app remains the general AI entry point, Doubao Work is aimed at office use cases, and Xiaodou is targeting the consumer personal assistant segment.

ByteDance’s Doubao names personal AI assistant “Xiaodou,” standalone app said to be in testing

ByteDance’s Doubao has named its personal AI assistant product “Xiaodou,” with a standalone app version also in the plan, according to a Sept. 30 report by Dujia cited by ChainCatcher. The report said the name was finalized during this summer break period and that the product remains in internal testing, with the final public-facing version still subject to change. A separate Sept. 29 report from Sina Tech said Doubao is speeding up work on a personal assistant product and plans to deeply integrate an exploratory internal project code-named “Spell” with Doubao’s existing product lineup. The new product is expected to launch externally relatively soon. As of publication, Doubao had not responded. The report also placed Xiaodou in the context of China’s Personal Agent race. In that lineup, Doubao’s main app handles general conversation, Doubao Work targets enterprise office use, and Xiaodou is aimed at the consumer personal assistant segment. Tencent was previously reported to be secretly developing Handy Bot, while Alibaba’s Qwen team has also proposed building a user-owned Personal Agent. No mature, mass-produced always-on personal Agent product has yet emerged in China, with most offerings still in internal testing or gray rollout preparation.

ByteDance’s Doubao adds travel booking, ride-hailing and navigation services

ByteDance’s AI assistant Doubao has added a set of travel-related services, according to a Sept. 30 report by Yicai cited by ChainCatcher. The product now lets users complete tasks such as flight booking, train ticket purchases, ride-hailing and route navigation directly through natural-language requests. Examples cited in the report include asking Doubao to book a flight from Beijing to Shanghai for the next day or to call a car to Beijing Capital Airport. Doubao then identifies the user’s intent and connects to the relevant service, removing the need to switch between multiple apps. On partnerships, the report said Doubao works with Flight Manager and High-Speed Rail Manager for flight searches, price comparison, online booking and order management. For ride-hailing, it partners with platforms including Caocao Mobility, while navigation services are supported through platforms including Baidu Maps. The report was written by reporter Lü Qian and edited by Yujian.

Meta’s Muse AI assistant accused of exposing user’s home address

Meta’s newly launched Muse AI assistant is facing scrutiny after tech YouTuber Matt Robb said the tool exposed his home address to a stranger after being authorized to access his Facebook Marketplace account. In a post on Threads, Robb said screenshots from the interaction showed Muse acknowledging the mistake. The same screenshots also indicated that the assistant agreed to a deal at a price far below expectations and did not notify him in time. The incident comes only weeks after Meta introduced Muse as a personal AI assistant and highlighted its safety features. Meta had positioned the product as part of its push to keep pace with rivals including Anthropic and OpenAI. The case is now drawing attention to a broader issue around AI agents: whether systems given permission to act on behalf of users can safely handle private and sensitive information without causing unintended disclosure or unwanted transactions.

OpenAI’s mysterious “o” assistant surfaces in code ahead of Sept. 29 DevDay

Evidence pointing to a new OpenAI product called “o” has surfaced in ChatGPT code and user-facing upgrade text, suggesting the company may unveil an always-on AI assistant at its Sept. 29 developer event. A developer identified as Chetaslua reportedly found a direct internal note stating, “Lowercase o is the assistant's product name,” while other references included the phrase “o, your always-on assistant,” a display-name setting, and an “-o” email suffix in configuration logic. The material cited in the source describes “o” as a long-running agent built to stay active in the cloud rather than stop after each prompt-response turn. Reported features include support for 63 languages, a “Fast Mode,” a hosted sandbox for persistent execution, and a shared message board for multiple agents handling different roles such as planning, research, coding, and review. The article also says access is tied to higher-priced tiers: $100 Pro Lite, $200 Pro, and an unreleased $500 Pro Max, while $20 Plus and Codex Plus users are excluded. It frames that split as a sign OpenAI is separating coding assistants from agents built to carry out broader work. OpenAI has not formally confirmed those details in the provided material, but the Sept. 29 DevDay is presented as the key date to watch.
