Synopsis
OpenAI unveils GPT-5.5, its most advanced model for research, capable of handling complex tasks with minimal guidance. This new AI can plan, use tools, and self-correct, marking a significant step towards machines accelerating AI research and potentially AGI. It's now available to Plus, Pro, Business, and Enterprise users.Listen to this article in summarized format
In a blog post, OpenAI claimed that users do not need to carefully manage every step. They can give GPT-5.5 a messy, multi-part task and let it plan, use tools, check its work, handle uncertainty, and continue working through challenges.
The company highlighted improvements in areas such as agentic coding, computer-based tasks, knowledge work, and early-stage scientific research.
"What is really special about this model is how much more it can do with less guidance," OpenAI cofounder and president Greg Brockman said at a briefing with journalists, as reported by news site AFP. "It can look at an unclear problem and figure out just what needs to happen next."
"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.
The blog added: “GPT-5.5 delivers this step up in intelligence without compromising on speed: larger, more capable models are often slower to serve, but GPT-5.5 matches GPT-5.4 per-token latency in real-world serving, while performing at a much higher level of intelligence.”
OpenAI further said that artificial general intelligence, or AGI, where machines can match or surpass human thinking, is no longer purely theoretical. Systems that can conduct research and refine themselves represent meaningful progress in that direction.
Company executives described GPT-5.5 as "one of the clearest steps yet toward models that can accelerate AI research itself."
Safety
The company said it is launching GPT-5.5 with its most robust safeguards so far, aimed at limiting misuse while maintaining access for productive applications.
“We evaluated this model across our full suite of safety and preparedness frameworks, worked with internal and external redteamers, added targeted testing for advanced cybersecurity and biology capabilities, and collected feedback on real use cases from nearly 200 trusted early-access partners before release,” it said.
Availability
OpenAI said that GPT-5.5 is rolling out to Plus, Pro, Business, and Enterprise users in ChatGPT and Codex, and GPT-5.5 Pro is rolling out to Pro, Business, and Enterprise users in ChatGPT.
The company noted that API deployments require different safeguards, and that it is working closely with partners and customers on safety and security requirements to serve the model at scale. "We'll bring GPT‑5.5 and GPT‑5.5 Pro to the API very soon," it added
