OpenAI Releases GPT-6.1 Terra: Cost-Effective Model Focused on Computer Control, Image Analysis and Practical Automation

OpenAI has launched GPT-6.1 Terra, a new model positioned between its high-end GPT-6 Astra and more affordable options in the GPT-6 family. The model emphasizes real-world computer interaction, visual understanding of documents and interfaces, and reduced error rates rather than raw reasoning benchmarks. It supports a 1.05 million token context window, image inputs, and tool use through the Responses API while cutting input token prices by half compared with its predecessor. Published benchmarks show substantial gains on Terminal-Bench 4.0, OSWorld 2.1 and Agents' Last Exam, with error rates dropping sharply at both low and maximum reasoning levels. OpenAI stresses that the model still requires human oversight for high-stakes actions and does not directly process audio or video. The release targets developers and enterprises seeking reliable automation of repetitive multi-step tasks at lower cost than flagship models.

GPT-6 Astra Shows Strong Tool Use and Math Results but Trails in Text Quality Tests

OpenAI released GPT-6 Astra on 3 September 2026 with capabilities for long-horizon tasks involving code, documents and external tools. Independent benchmarks from Artificial Analysis, Epoch AI and others reveal a mixed picture: the model leads in Epoch Capabilities Index and certain coding agent tests yet falls behind Claude Fable 5.1 in text generation and some professional document tasks. Astra solved two previously open problems on FrontierMath Erdős and reached 99.9 percent on ARC-AGI-3 when paired with a state-preserving adapter. The model was rated Critical for cyber capabilities after scoring 100 percent on ExploitBench and discovering two previously unknown vulnerabilities. Pricing starts at $10 per million input tokens, 2.5 times higher than GPT-5.6 Sol, while real-world costs vary sharply depending on task length and retries.

OpenAI GPT-6 Astra Deploys Multi-Agent Parallel Processing, Increasing Local CPU Load and Security Risks

Early users of GPT-6 Astra have observed the model distributing complex tasks across multiple specialized agents that plan, solve, test code, verify results, and iterate after failures. This multi-agent approach enables faster handling of multi-step workflows compared to sequential chatbots. OpenAI states that Astra can control computers, operate browsers and applications, and install or test software, though it has not officially confirmed a native multi-agent architecture. Main computations run in the cloud, but agent tools can execute on user devices or corporate servers, leading to noticeable processor load when multiple agents compile code, launch browsers, run tests, and operate containers simultaneously. Corporate environments face added complexity as each agent requires virtual machines, sandboxes, internal data access, and careful environment cleanup. The increased autonomy has prompted OpenAI to strengthen monitoring of Astra actions and permission boundaries for subscribers of ChatGPT and enterprise clients.

OpenAI Unveils GPT-6 Astra: First Model Rated Critical for Cybersecurity with Record Computer-Use Performance

OpenAI has released GPT-6 Astra, positioning it as a major advance in agentic AI capable of directly operating computer interfaces through mouse, keyboard, and screen interaction. The model achieved 72.6% on the OSWorld 2.0 benchmark, nearly doubling speed compared with GPT-5.6 Sol while delivering higher quality results. On ARC-AGI-3 it scored 62.7% in standard mode and 99.9% with provider-adapted harness, prompting debate over benchmark methodology. Most notably, OpenAI assigned Astra a Critical rating under its Preparedness Framework, the first for any company model, after it autonomously discovered two previously unknown zero-day vulnerabilities in the V8 engine and chained exploits to escape sandboxes. The public version blocks advanced offensive requests, while vetted organizations gain access through the Daybreak Blue program. Independent evaluations show mixed general-intelligence gains but clear improvements in action-oriented tasks and reduced hallucination rates.

OpenAI GPT-6 Astra Reaches 100% Exploit Generation Accuracy on ExploitBench

OpenAI has unveiled GPT-6 Astra, its latest model that demonstrates unprecedented capability in generating working exploits from known vulnerabilities. The model scored a perfect 100% on ExploitBench, significantly outperforming the previous GPT-5.6 Sol at 78.5%. In tests involving recently disclosed vulnerabilities, Astra achieved arbitrary code execution in 39% of cases compared to 11.5% for its predecessor and discovered two previously unknown zero-day flaws. Due to these capabilities, OpenAI has restricted the public release to safe code analysis and patch development only, blocking requests for proof-of-concept exploits. Expanded access for vulnerability research and malware analysis will be provided through the Daybreak program to selected defenders, while the company adds stronger jailbreak protections and activity monitoring.
