2. OpenAI delays launch of custom GPT store

According to an internal memo reported on by Reuters on Friday, OpenAI has announced that they will be delaying the launch of its custom GPT store until early 2024. The memo states that the company is continuing to make improvements to the GPTs, and the firing and subsequent re-hiring of founder Sam Altman may have been a factor, but details for the decision have not yet been released to the public.

The company behind the explosive ChatGPT announced on November 6 that they would be rolling out versions of the software that users can custom-build for their specific needs and then share with other users. Tasks these custom GPTs could accomplish included teaching math and designing stickers. Plans were also in place to launch a GPT store at the end of November, where verified builders could list their GPTs.

As of press time, no alternative launch date has been provided by OpenAI.

3. Dell partners with AI startup Imbue

Dell (NYSE: DELL ) struck a deal with AI start-up Imbue worth US$150 million on Wednesday. The two companies have partnered up to build a high-performance computing cluster using Dell PowerEdge XE9680 servers with NVIDIA H100 Tensor Core GPUs. The system is already being used to train Imbue’s foundational model of an AI personal assistant that has advanced reasoning capabilities.

The terms of the deal allow Imbue to design and redesign its model thanks to Dell’s customizable hardware. Cloud providers, such as Google (NASDAQ: GOOGL ) or Amazon (NASDAQ: AMZN ), can limit start-ups down the road. In an interview with Bloomberg , Imbue co-founder Josh Albrecht said that was a major factor in their decision to partner with Dell. “We don’t want to be locked into a computing provider. (Using a cloud provider) would make it much harder for the software side to move off of that in the future. This allows us to be able to remain independent.”
