WASHINGTON — OpenAI, the San Francisco‑based artificial‑intelligence company, has pulled the rollout of its GPT‑6.1 model, the most advanced generative‑language system it has built to date, after internal reviews flagged significant safety risks. The decision was announced on Tuesday, 29 September 2026, and follows a series of tests that revealed the model could produce disinformation, manipulate public opinion, and generate content that could be used in phishing or fraud campaigns.
Safety review triggers halt
OpenAI’s internal safety team reported that GPT‑6.1, named Astra, exhibited higher propensity for “hallucinations” and could produce plausible but false statements when prompted with ambiguous queries. The model also demonstrated an ability to bypass content filters that had been effective in earlier releases. In a statement released to the press, the company said it had decided to postpone the public launch until it could strengthen the model’s alignment mechanisms and improve its ability to detect and refuse harmful requests.
Industry reaction
Tech analysts noted that the move comes at a time when governments worldwide are tightening regulations on large language models. The European Union’s AI Act, which came into force in 2025, requires high‑risk AI systems to undergo rigorous testing and certification. In the United States, the National Institute of Standards and Technology (NIST) has issued guidance on AI safety that many firms are still adapting to.
Several competitors, including Microsoft and Google, have announced that they will continue to roll out new models under stricter oversight. A spokesperson for Microsoft said the company would “continue to prioritize safety and transparency” in its upcoming releases. Google’s AI division reiterated its commitment to responsible deployment, citing its own “Safety‑First” framework.
Regulatory context
OpenAI’s decision follows a series of high‑profile incidents involving earlier models. In 2024, a GPT‑4.5 iteration was temporarily pulled from commercial use after a user discovered it could generate convincing phishing emails. The company’s CEO, Sam Altman, had previously stated that the organization would “never release a model that could be used to cause harm.”
In the United Kingdom, the Office for Artificial Intelligence has issued a warning that large language models could be used to produce “deep‑fake” text that might influence elections. The UK’s Office for Artificial Intelligence has also called for a “robust governance framework” for AI systems that can produce realistic text.
Future plans
OpenAI said it will continue to develop GPT‑6.1, but the release will be delayed until it can demonstrate that the model meets the company’s safety standards and complies with international regulations. The firm has also announced a partnership with the AI Safety Institute to conduct third‑party audits of its models before public deployment.
In a statement to the press, OpenAI’s chief technology officer noted that the company would “maintain transparency with stakeholders and provide regular updates on the progress of safety improvements.” The company also confirmed that it would keep its existing GPT‑4.5 and GPT‑5 models in operation while it works on the next iteration.
Global impact
The cancellation has implications for businesses that rely on AI for customer service, content creation, and data analysis. Several startups that had planned to integrate GPT‑6.1 into their products have postponed their launch dates. The move also raises questions about the pace of AI innovation and the balance between rapid deployment and responsible stewardship.
OpenAI’s decision is likely to influence other firms in the sector to reassess their own safety protocols. The company’s transparency in announcing the halt is seen as a positive step toward building public trust in AI technologies.
