OpenAI started rolling out GPT-6 Astra by opening access to its next-generation large language model. Astra scored 98% on the FrontierMath Tier 4 test of 50 math challenges, and the rollout had been delayed for several weeks after the model qualified as “critical” for hacking many well-protected systems without human input. OpenAI will now expand Astra to ChatGPT, Codex, and its API over the coming days under the Daybreak program and provide $1 billion in credits for cybersecurity research, training, and support.
OpenAI announced Daybreak for Frontline Defenders, expanding its Daybreak governed cyber defense stack to help frontline defenders protect critical services worldwide. The initiative continues OpenAI’s $1 billion commitment to expand subsidized access, training, technical support, and partnerships, including a U.S. pilot with MS-ISAC. Access and support for defensive cyber AI tools expand for state and local cyber teams, including coverage focused on systems used for water, electricity, local government, and banking.
OpenAI released GPT-6 Astra as a hosted computer-use model aimed at completing multi-step tasks across tools instead of self-hosted chatting. The model is provisioned with a 1,050,000-token context window. Access is limited to OpenAI’s Trusted Access and Daybreak programs, adds experimental config-based long-context note retention for agents, and is priced at $10 per million input tokens and $50 per million output tokens.
GPT-6 Astra launched with claims that it can saturate top-level reasoning benchmarks and perform end-to-end AI engineering tasks, including training model choices, labeling data, running pipelines, deploying and debugging systems, and managing subagents. It achieved 99.9% on ARC-AGI-3 and 97.6% on FrontierMath’s hardest versions, with testing estimating $6 per hour at 33 tokens per second. As a result, teams can use Astra to automate much of the AI engineering workflow in one shot and reduce the need for separate human labor for these operational tasks.

OpenAI is rolling out GPT-6 Astra to a limited set of organizations before expanding availability to all ChatGPT Plus, Pro, Business, and Enterprise users and to the OpenAI API and AWS. The API pricing is $10 per million input tokens and $50 per million output tokens. Model access expands broadly across ChatGPT and developer platforms, and Astra’s published benchmark results emphasize improvements in ARC-AGI 3 (99.9%) and security/long-context tasks.
OpenAI introduced GPT-6 Astra, positioning it as its most capable model while keeping the frontier version mostly locked behind staged access. Astra is priced at $10 per 1M input tokens and $50 per 1M output tokens via the API. Access expands over coming days from selected Daybreak cybersecurity customers and limited bounded tasks, while the model also includes built-in refusals and additional protections to restrict advanced misuse.
GPT-6 Astra posted a 98.6% result on OpenAI’s ARC-AGI-3 benchmark, far above GPT-5.6 Sol’s 7.8%. The score was evaluated via the Responses API harness with two settings changed for real-world use, and OpenAI notes other models used different setups. The result broadens Astra’s performance claims across other benchmarks and is paired with math progress reports, while OpenAI stresses that the ARC-AGI-3 setup makes direct comparisons less straightforward.
OpenAI, Anthropic, xAI, and Google experienced overlapping service interruptions affecting their cloud-based AI model offerings over several hours Thursday morning. Anthropic reported elevated errors starting at 9:23 am ET and said a fix was deployed with resolution by 12:16 pm. Service degradation and partial outages were mitigated and marked resolved for the impacted models as fixes were deployed.
OpenAI launched GPT-6 Astra as its newest flagship model and said it marks the start of an “AGI era.” Astra’s API pricing is $10 per 1 million input tokens and $50 per 1 million output tokens. Access begins with enterprise customers on OpenAI’s Daybreak program and then expands to Plus, Pro, Business, and Enterprise plus the API and AWS in the coming days.
OpenAI released Astra, a new AI model, and positioned it as its most capable and aligned option yet. OpenAI president Greg Brockman said Astra is “most intelligent” and that OpenAI “tested Astra on a variety of security benchmarks,” with availability starting Thursday for OpenAI customers using Daybreak. Astra is rolled out to Daybreak customers first and then expanded over the following week via Pro, Plus, Enterprise, Business plans and the API, alongside new safeguards and monitoring tradeoffs tied to opaque recurrence.
OpenAI started publicly previewing how it evaluated Astra before release, tying the process to the model’s capabilities. The preview focuses on safeguards added after Astra’s capabilities were assessed, specifically to control what it can do. As a result, Astra’s release is accompanied by stronger, capability-based safety measures.
The newsletter points to an additional teaser post from OpenAI’s account as more “launch-day-looking” signaling. The only concrete detail provided is that it is “another teaser.” This adds speculation about timing for something called “Astra,” with no confirmed launch date mentioned.
OpenAI’s account posted additional “launch-day-looking” teasers. The posts suggest a launch “today,” though they do not prove one will happen. The added activity increases speculation about timing for a new model release.
The official ChatGPT account teased a message that “The stars are almost aligned,” tied to an upcoming livestream. The teaser is framed as “Subtle!” in the newsletter. As a result, expectations are rising for what will be announced during the livestream.
OpenAI Codex for enterprise coding agents is being deployed with a customer-operated LiteLLM gateway on Amazon ECS to centralize control over generative-code model access and usage. The validated walkthrough targets the us-east-1 region and uses an example gateway alias openai.gpt-5.5 mapped to bedrock_mantle/openai.gpt-5.5. Codex request traffic is routed from developers’ workstations through the ECS-hosted LiteLLM gateway to Amazon Bedrock, enabling enforced model routing, budgets, rate limits, and gateway telemetry while keeping tool execution local.
OpenAI announced GPT-6 Astra as its next major AI model and said it advances capabilities for tasks like cybersecurity, professional work, software engineering, science, and computer use.
