## Introducing GPT-6 Astra
GPT-6 Astra is OpenAI's most intelligent and aligned model to date, combining years of research in pre-training, reinforcement learning, and alignment.

> We’re introducing GPT‑6 Astra, the world’s most intelligent and aligned model.
## Saturating frontier benchmarks
The model sets new benchmark highs, reaching 98% on FrontierMath Tier 4, 99.9% on ARC-AGI-3, and 100% on ExploitBench.

> Not only is this the best model we’ve ever tested, but it also represents a meaningful step change in frontier-model performance
## Cheaper scientific workflows
On Terminal-Bench Science 0.1, Astra completed research workflows with a 64.6% success rate while reducing estimated API costs by roughly 31%.
## Unprecedented scope discipline
When faced with impossible tasks, Astra never went beyond its authorized target, compared to previous models that exceeded scope 48% of the time.
## Next-level computer control
Astra autonomously operates desktop applications to fill out forms, update CRMs, run web research, execute software installs, and conduct QA tests.
## Faster knowledge work execution
The model scored 59.3% on Agents' Last Exam while using 65% fewer output tokens, completing OSWorld tasks in 47% less time than previous generations.
## Accelerating physical hardware design
Astra can perform complex printed circuit board layouts in KiCad, placing components and routing copper connections to accelerate hardware engineering.
## Optimized harness for speed
Paired with an updated Codex harness, Astra completes web and desktop automation tasks 1.9 times faster on the Mind2Web benchmark.
## Professional document creation
The model adheres strictly to enterprise templates, generating polished slide decks, spreadsheets, and reports that match existing visual and writing styles.
## Precision 3D CAD modeling
On BenchCAD, Astra reconstructed 3D objects from multi-view renders with a 95.9% geometric overlap score at up to 86% lower API costs.
## Generating interactive 3D worlds
Astra can model architectural assets in Blender and assemble them into walkable Unreal Engine 5 scenes or full WebGL browser games from text prompts.
## Smart ambiguity resolution
When instructions lack detail, Astra asks targeted questions asynchronously while continuing unblocked work, making sensible defaults when unanswered.
## Staying oriented through feedback
Unlike older models that lost track of original goals when receiving mid-task feedback, Astra adapts to new requirements without dropping prior constraints.
## State of the art in coding
Astra hit 57.9% on Terminal-Bench 4.0, outperforming rival models on complex terminal engineering tasks with significantly lower token consumption.

> produces code that requires less iteration to reach production quality
## Persistent notes across long sessions
Codex now allows Astra to keep structured notes across context windows instead of relying on destructive compression summaries that erase vital details.
## Solving open math problems
Astra helped prove that infinitely many prime pairs occur within a distance of 186, while also breaking an 80-year-old bound on large prime gaps.

> The story is: end of one era, start of another.
## Navigating complex scientific tools
Hitting 96.0% on GPQA Diamond, Astra can operate life-science software directly to inspect genetic sequencing quality and visualize data variations.
## Reaching critical cyber thresholds
Astra triggers the Critical threshold under OpenAI's Preparedness Framework, scoring 100% on ExploitBench and 42.4% on ExploitGym.
## Uncovering zero-day vulnerabilities
Evaluating recent Chrome vulnerabilities, Astra discovered two unknown zero-day flaws while achieving an 88% single-pass score on SRE-Bench.
## Strict cyber guardrails
To prevent misuse, Astra refuses to build proof-of-concept exploits, while defensive capabilities like patching are gradually opened through OpenAI Daybreak.
## Industry-leading safety alignment
In computer-use stress tests, Astra caused just 2.4% misaligned outcomes and recorded a 0% rate of attempting to bypass system safety reviews.
## Reduced capability hallucinations
Astra is three times less likely than GPT-5.6 Sol to misrepresent its capabilities or make false claims about what tools it can access.
## Real-time misalignment monitoring
OpenAI is deploying production classifiers that monitor Astra's chain-of-thought reasoning and actions, automatically halting unauthorized behavior.
## Rollout and API pricing
Astra is rolling out across ChatGPT tiers, API ($10/M input, $50/M output tokens), Azure, and AWS Bedrock, with a 2x Fast Mode available for developers.
## Key takeaway

GPT-6 Astra pairs unprecedented computer use and coding performance with rigorous alignment and real-time safety monitoring.
