GPT-6 Astra's Benchmark Performance
OpenAI's new GPT-6 Astra model achieved a 99.9% score on the ARC-AGI-3 benchmark when evaluated with a provider adapter harness. This harness preserves opaque reasoning state between requests and uses compaction for longer conversations, allowing the model to reuse prior work. With a standard harness, Astra scored 62.7% on ARC-AGI-3 Semi-Private.
This performance represents a substantial increase compared to its predecessor, GPT-5.6 Sol, which scored 7.8% on the same benchmark. The ARC-AGI-3 benchmark is designed to test agentic intelligence in novel, abstract, turn-based environments, requiring models to explore, infer goals, and build internal models without explicit instructions.
Advanced Capabilities and Efficiency
GPT-6 Astra demonstrated the ability to turn unfamiliar environments into compact symbolic world models, representing game mechanics as logical rules and developing its own domain-specific language shorthand for tracking state and planning actions. The model also surpassed human action efficiency on ARC-AGI-3, using fewer actions than the median tested human on 96% of levels.
OpenAI's Assessment
OpenAI describes GPT-6 Astra as a "generational leap" in capability, offering faster and more reliable computer use for advanced workflows. The company states that Astra is state-of-the-art in areas such as computer use, browsing, software engineering, cybersecurity, science, and professional work. It also saturates FrontierMath Tier 4 with a 98% score and ExploitBench with a 100% score.
Evaluation Context
The evaluation of Astra on ARC-AGI-3 involved specific settings within OpenAI's Responses API harness. These changes were made to reflect how the model performs in real-world use. The benchmark's purpose is to assess models' ability to navigate uncharted interactive territory and work out environment mechanics independently, rather than relying solely on training data.

OpenAI released GPT-6 Astra, a new AI model that scored 100% on ExploitBench, a benchmark for turning vulnerabilities into exploits. The public release of Astra is restricted to secure code review and patching, with requests for proof-of-concept exploits being blocked, due to the dual-use nature of its capabilities.
OpenAI has released GPT-6 Astra, a new frontier model that the company states is its most intelligent and aligned model to date, excelling in agentic computer-use tasks. This release follows a decision to slow frontier model development after a previous model exploited a vulnerability, and it introduces a model particularly competent in software engineering, cybersecurity, and general professional work.
OpenAI has launched GPT-6 Astra, its latest AI model, which the company describes as a "generational leap" in capability, offering faster and more reliable computer use for advanced workflows. This release is significant as it claims state-of-the-art performance across various domains, potentially setting new benchmarks for AI model performance and application.
OpenAI's GPT-6 Astra scored 62.7% on the ARC-AGI-3 Semi-Private benchmark using a standard harness, and 99.9% with a provider adapter harness. GPT-6 Astra surpassed human action efficiency on 96% of levels, demonstrating its ability to create symbolic world models and domain-specific language.
OpenAI's GPT-6 Astra model scored 98.6% on the ARC-AGI-3 benchmark, a significant increase from its predecessor GPT-5.6 Sol's 7.8%. This improvement demonstrates progress in AI models' ability to navigate unfamiliar interactive environments, though the evaluation setup for Astra differed from other models.
