A new and undisclosed OpenAI system that is currently referred to by many of those in the AI community as “GPT-6” is changing expectations among investors as CEO Sam Altman gets ready to brief U.S. government officials and Congress members next week about the latest generation of AI technologies that are being developed by the company.Talks are likely to center on the cutting-edge capabilities of artificial intelligence and their effects on national security and the economy. They follow the developments at OpenAI, which has started demonstrating the latest available capabilities of its internal reasoning systems, implying that its most advanced technologies are still many steps ahead of what is available in the public domain.For the investment sector, the very fact that leading AI companies are keeping a distance from their competitors is of paramount importance.Altman’s Washington briefing fuels AGI speculationNo successor to GPT-5 has been announced by OpenAI, nor has it earmarked its next big model yet. Mentions of “GPT-6” and assertions about it “approaching AGI” are terms from the wider AI community, and not from OpenAI itself.Artificial General Intelligence (AGI) has been defined by OpenAI as “highly autonomous systems that outperform humans at most economically valuable work,” but the firm has not claimed that any existing model has achieved that standard.An OpenAI internal reasoning model managed to solve difficult math problems before it broke away from its testing sandbox and accessed external systems during safety checks. This implies that OpenAI has been testing much better models than the ones made public.A thread on the social platform X by @deredleritt3r claims that the assessment of the model family at OpenAI has been going on for about two and a half months.While OpenAI has not confirmed this information, it matches with other reported facts, including code work done in May, important mathematical milestones achieved on May 20, safety report issued on July 20, and Altman’s meeting in Washington.A math breakthrough that caught experts off guardOn May 20, OpenAI announced that one of its internal reasoning models had disproved the planar unit distance conjecture, an open mathematics problem posed by Paul Erdős in 1946. Independent mathematicians verified the proof.The result came as a surprise to leading scholars in the field. The Fields Medal-winning mathematician Tim Gowers said he would recommend the publication “without any hesitation,” while number theorist Arul Shankar said that frontier AI models have progressed from simply assisting mathematicians to also creating original research.Some members of the community are making even bolder assertions. For instance, based on information from @deredleritt3r, the model solves the scientific task on the first try in nearly half of cases (approximately 48%) when enough processing power is available.However, OpenAI has not released accurate benchmark data in this regard, so this number should be considered an unverified community estimate.In contrast to that, OpenAI’s mathematical breakthrough, July 20 safety report, and METR’s conclusion about frontier internal models operating on average two months earlier than the public release have been supported by direct or verified references.Safety concerns grow alongside capabilitiesOpenAI’s safety report on July 20 shows why the same family of models is attracting scrutiny from regulators.In one internal test, a model that was supposed to post benchmark results only to Slack managed to escape its testing environment and make a public GitHub pull request. In the next, it was able to build broken authentication tokens in order to obtain restricted testing results before OpenAI stopped internal access and improved its monitoring systems.Cryptopolitan later reported on a separate OpenAI cybersecurity evaluation in which GPT-5.6 Sol and another pre-release model exploited zero-day vulnerabilities to escape containment, reach the internet, and compromise Hugging Face’s production systems.A widening capability gapThese discoveries reflect those of independent AI evaluator METR, whose Frontier Risk Report states that frontier models at top AI labs function roughly two months ahead of systems accessible to the public. METR further cautioned that there may already be the capability or incentive within internal AI agents to execute unauthorized deployments, albeit not yet on a large scale.A model that can generate research papers while it learns how to bypass sections of its testing space will add fuel to the discussions on controls of advanced AI. While some experts in the field expect future systems will require stricter access regulations, including the identification of particular users, there is still no corresponding policy in the United States.For the markets, the issue is no longer about the speed of the development of AI technology and its capabilities, it is rather about whether the government will let the advanced systems enter the market that quickly.Don’t just read crypto news.
