American Marconi Wireless News - OpenAI says new model adept at making AI better

GPT-5.5 was billed as a "new class of intelligence" and comes just months after the launch of its predecessor.

"What is really special about this model is how much more it can do with less guidance," OpenAI co-founder and president Greg Brockman said at a briefing with journalists.

"It can look at an unclear problem and figure out just what needs to happen next."

The model is particularly adept at "agentic" coding and computer use in which digital assistants independently tend to tasks as directed, according to the San Francisco-based startup behind ChatGPT.

"It feels like it's setting the foundation for how we're going to do computer work going forward," Brockman said.

In the short term, OpenAI is focused on letting humans act as "orchestrators" while AI models do the "heavy lifting," chief research officer Mark Chen said at the briefing.

OpenAI was adamant that it built its strongest safeguards to date into GPT-5.5 "to reduce misuse, especially for bio and cyber capabilities."

That means a ramped-up tendency for the latest model to refuse requests to attempt "cyber-related activities," OpenAI executives said.

Rival company Anthropic has held back a new Claude Mythos AI model deemed so adept at finding vulnerabilities in software it could be a boon for hackers.

Anthropic restricted the release of Mythos to select major tech firms to give them a head start in fixing cybersecurity vulnerabilities and is looking into reports of unauthorized use of the model.

"There are enough model releases that it's probably going to be hard to distinguish one from another," Brockman mused during the briefing.

"This model is a real step forward towards the kind of computing that we expect in the future, but it is one step, and we expect to see many."

According to OpenAI, artificial general intelligence in which computers think as well or better than people is no longer theoretical, and AI models that research how to essentially improve themselves take the world further in that direction.

The executives described GPT-5.5 "as one of the clearest steps yet toward models that can accelerate AI research itself."
