[ITmedia PC USER] “ChatGPT Classic” desktop app will end on January 30, 2027 / Bluetooth SIG announces adoption of new feature “High Data Throughput” Communication speed up to 7.5Mbps

This is a series where you can "binge-read" news on weekends that you may have missed but are a little curious about. This time, let's check out the main news released mainly during the week of November 1st!

“ChatGPT Classic” desktop app will end on January 30, 2027

OpenAI will end the provision of ChatGPT's old desktop application "ChatGPT Classic" on January 30, 2027. Currently, when you start Classic, a dialog appears informing you that the service is discontinued and directing you to download the new ChatGPT desktop app. The dialog explains that all chat history will be carried over and that you can resume where you left off.

On July 9, the company released a new desktop app for macOS and Windows that combines Chat (questions and conversations), Work (research and analysis, creation of documents, spreadsheets, and presentations), and Codex (software development) into one.

The old app remained under the name "ChatGPT Classic" and migration was not required. While it will continue to provide model updates, bug fixes, and security patches, it said new agent features such as Work and Codex will only be available in the new app. With this announcement, there is a limit to the period during which you can continue to use Classic.

Additionally, OpenAI's help article ``Moving to the new ChatGPT desktop app,'' which guides you through the migration process, does not mention the end date as of November 6, and still states that you can continue to use Classic.

Bluetooth SIG announces adoption of new feature "High Data Throughput" Communication speed increases to up to 7.5 Mbps

Bluetooth SIG (SIG) announced on November 4th that it has officially adopted Bluetooth High Data Throughput (HDT), a new feature that speeds up Bluetooth Low Energy (LE) communications. HDT is included in "Bluetooth Core 7.0" as an optional feature.

HDT adds a new physical layer (PHY) to Bluetooth LE with a modulation method that is resistant to noise and interference, and increases the maximum bit rate to 7.5Mbps. Nearly 4 times faster than the current LE 2M PHY (2Mbps). According to a blog published by SIG in July, QPSK and QAM will be used for the modulation method, and the bit rate will be in five stages: 2/3/4/6/7.5Mbps.

Since the rate can be switched for each packet, it is possible to balance speed and stability according to the radio wave conditions. In early demonstrations by member companies, the transfer of a several MB file, which takes about 16 seconds using the current method, has been reduced to about 4 seconds.

In addition to speed, SIG says it will also improve frequency usage efficiency, power savings, and communication stability. This is because the data can be sent in a short time, allowing the wireless part to spend more time in a low power consumption state.

The first major application will be wireless audio, with standardization of specifications for lossless and high-resolution sound source transmission, multi-channel surround sound, and spatial audio. SIG expects to release these specifications in 2027. In addition, it is expected to be used for XR, smart glasses, devices with AI processing, sensor data synchronization of smart watches, firmware updates, etc.
