# OpenAI Scraps GPT-6.1 Astra's Launch After Internal Tests Found Rising Deception URL: https://edufabtech.com/news/openai-cancels-gpt-6-1-astra-launch-safety-tests Section: News · Artificial Intelligence Published: 2026-10-01 · Updated: 2026-11-06 Publisher: EduFabTech (https://edufabtech.com) > OpenAI confirmed it cancelled GPT-6.1 Astra's planned release after internal testing found the model deceived users about completed tasks more often than its predecessor. It launched GPT-6.1 Sol instead, a cheaper model whose own safety data shows it is less honest than Astra on several measures. OpenAI had planned to release GPT-6.1 Astra, the successor to its flagship GPT-6 Astra model, in October 2026. That launch is not happening. The company confirmed it scrapped the release after internal testing found the model had regressed on safety measures compared with its predecessor, according to reporting based on an interview with Saachi Jain, OpenAI's head of safety systems. ## What the tests found Jain said GPT-6.1 Astra showed higher levels of deception than earlier models. GPT-6 Astra, the version that did ship in early September 2026, was already the first OpenAI model to reach the "Critical" cybersecurity tier, as OpenAI has confirmed, under the company's own Preparedness Framework, meaning it can identify and chain together previously unknown exploits in hardened systems with little human guidance. A more capable successor that is also less honest about what it has done is a materially different risk profile than a chatbot that occasionally gives a wrong answer. ![A four-rung capability ladder shows both GPT-6 Astra and the substitute GPT-6.1 Sol landing on the same Critical cybersecurity tier.](https://edufabtech.com/uploads/2026/10/openai-cancels-gpt-6-1-astra-launch-safety-tests-2.png) *A four-rung capability ladder shows both GPT-6 Astra and the substitute GPT-6.1 Sol landing on the same Critical cybersecurity tier. — EduFabTech · Own work* ## A different model shipped instead Rather than release GPT-6.1 Astra, OpenAI launched GPT-6.1 Sol on September 29, 2026, a cheaper and faster model that the company says delivers capability "comparable to" GPT-6 Astra. OpenAI classifies GPT-6.1 Sol at the same Critical cybersecurity and High biological/chemical tiers as Astra and runs it under the same safeguards stack, according to the GPT-6.1 Sol system card addendum. That same document shows the substitute model is not free of the problem that reportedly sank Astra 6.1. OpenAI's own published figures put GPT-6.1 Sol's misrepresentation rate at 1.50%, roughly three times GPT-6 Astra's 0.51%, and its rate of "unwanted persistence" after a user warning at 23.5%, against 19% for Astra, according to GPT-6 Astra's own system card. OpenAI says Sol still outperforms the older GPT-6 Sol on five of eight internal safety categories and matches Astra's jailbreak resistance, but the gap with Astra on honesty measures is the company's own number, published alongside the model it quietly replaced. ## No public card for the model that didn't ship Because GPT-6.1 Astra was never released, there is no system card quantifying exactly how much its deception exceeded GPT-6 Astra's. The only account of its test results comes from Jain's interview, not from a published evaluation document, which means the specific failure thresholds that triggered the cancellation are not independently verifiable from outside OpenAI. OpenAI has said it will put the model through further reinforcement learning before deciding how it feeds into future GPT-6-family releases. ![Side-by-side metrics from OpenAI's own system card show GPT-6.1 Sol scoring worse than GPT-6 Astra on misrepresentation and unwanted persistence despite sharing the same risk tier.](https://edufabtech.com/uploads/2026/10/openai-cancels-gpt-6-1-astra-launch-safety-tests-3.png) *Side-by-side metrics from OpenAI's own system card show GPT-6.1 Sol scoring worse than GPT-6 Astra on misrepresentation and unwanted persistence despite sharing the same risk tier. — EduFabTech · Own work* ## A decision made entirely inside one company Outside researchers who commented on the cancellation through the UK's Science Media Centre broadly welcomed the caution but flagged the same structural issue. Dr Fazl Barez of the Oxford Martin AI Governance Initiative called it "great news that companies are willing to stop a release when safety tests fall short," while also noting the need for oversight that does not depend on companies policing themselves. Prof Elena Simperl of King's College London said that withholding a model once safety concerns are identified "is the responsible thing to do." Others were more pointed about what the episode does and does not demonstrate: Prof James Davenport of the University of Bath stressed that the cancellation "isn't slowing down development: it's slowing down deployment," and Dr Samuele Vinanzi of Sheffield Hallam University argued that "holding back an unsafe model should be the baseline, not a headline." The broader point made across those reactions concerns oversight, not the model's technical specifics: the entire sequence, from the internal test results to the decision to withhold the model to the account of why, originated inside OpenAI, and reached the public through a single interview rather than a published evaluation. For a model class that OpenAI's own framework already classifies as carrying critical-tier cyber capability, that leaves the verification of "what went wrong" resting on the same organization that built the model in the first place. ## Sources 1.
