OpenAI has launched\u00a0GPT-5.1-Codex-Max, a specialized coding model designed to handle complex development tasks autonomously.<\/p>\n
The new system represents a significant leap in agentic AI capabilities, enabling machines to work on coding projects with minimal human intervention. GPT-5.1-Codex-Max operates differently from general-purpose AI models<\/a>.<\/p>\n Built specifically for software engineering, the model features\u00a0compaction technology\u00a0that enables it to process millions of tokens in a single session.<\/p>\n This breakthrough means developers can assign extensive refactoring projects, debugging sessions, and multi-hour agent loops to the AI.<\/p>\n Which completes them independently without losing context or coherence. The model can sustain work for extended periods.<\/p>\n In internal testing, GPT-5.1-Codex-Max completed tasks running for over 24 hours, automatically managing its context window by compacting sessions when necessary.<\/p>\n This capability transforms how teams approach large-scale code<\/a> modernization and complex system maintenance. Performance benchmarks demonstrate substantial improvements over previous versions.<\/p>\n On SWE-bench Verified evaluations, GPT-5.1-Codex-Max achieves 77.9% accuracy compared to 73.7% from its predecessor.<\/p>\n More notably, the model uses 30% fewer thinking tokens while delivering superior results, directly translating to reduced computational costs for developers.<\/p>\n Frontend design tasks showcase these efficiency gains effectively. GPT-5.1-Codex-Max produces high-quality interfaces with approximately 27,000 thinking tokens, compared to 37,000 for older models.<\/p>\n Requiring fewer tool calls and generating more efficient code. The enhanced capabilities bring responsibility.<\/p>\n OpenAI acknowledges<\/a> that advanced coding models can, in theory, assist in cybersecurity attacks. However, the company states it hasn\u2019t observed meaningful abuse at scale.<\/p>\n The team has already disrupted cyber operations by attempting to misuse the model. GPT-5.1-Codex-Max runs in a secure sandbox by default.<\/p>\n File operations remain confined to designated workspaces, and network access stays disabled unless explicitly enabled.<\/p>\n OpenAI recommends keeping Codex restricted, as enabling internet connectivity introduces prompt injection vulnerabilities<\/a>. The company advises developers to review all AI-generated code before deployment.<\/p>\n Codex produces terminal logs and cites tool calls, reducing bug risks, but should complement rather than replace human code reviews.<\/p>\n GPT-5.1-Codex-Max is now available through Codex for ChatGPT Plus, Pro, Business, Edu, and Enterprise subscribers. API access is coming soon.<\/p>\n Internally, 95% of OpenAI\u2019s engineers use Codex weekly, and adoption correlates with approximately 70% more pull requests shipped.<\/p>\n The model represents progress toward reliable AI coding partners that enhance developer productivity while maintaining security standards.<\/p>\n Follow us on Google News<\/a>, LinkedIn<\/a>, and X<\/a> for daily cybersecurity updates.
