OWN YOUR WEIGHTS

Owning their own weights can be too complex for most businesses. There needs to be a service where companies can bring their workloads to and get back a task-specific model built on their data, tuned to their tasks, running on infrastructure they control. This would provide the benefits of owning their own weights without having to maintain their own models. It would also allow them to continually build and fine-tune the weights and improve their models.

OPENAI MAY HAVE MADE A FATAL MISSTEP IN COPYRIGHT FIGHT WITH NEWS ORGS

News organizations suing OpenAI have accused the AI firm of repeatedly lying for years to conceal evidence of infringement that could hobble its defense. OpenAI privacy engineer Vincent Monaco has revealed that OpenAI misled the court for two years about the cost and burdens of searching ChatGPT logs. OpenAI has pretended from the earliest stages of the case that it did not have the technical ability to search large anonymized samples of ChatGPT logs when it had actually already conducted such searches prior to the start of litigation. The discovery may lead to serious sanctions against OpenAI.
