OpenAI has announced the GPT-5.3 Codex model, its new Frontier platform, aimed at enhancing AI development, coding efficiency, and large-scale deployment. The move signals a stronger focus on advanced users and enterprise-grade AI solutions.
OpenAI has launched a new AI model called GPT-5.3 Codex, along with a new enterprise platform, Frontier. GPT-5.3 Codex is aimed at boosting Codex, OpenAI’s agentic coding tool marketed for software developers. Frontier aims to help enterprises build, deploy and manage AI agents.
Earlier versions of Codex mainly focused on helping developers write and review code. With the new GPT-5.3 Codex model, OpenAI says Codex can now do much more. According to the company, the model turns Codex into an agent that can do ‘nearly anything developers and professionals do on a computer, expanding who can build software and how work gets done.’
OpenAI stated in the blog post, “GPT-5.3 Codex performs better on several benchmarks and is 25 percent faster than the previous version.” The company also claimed, “New model can create highly functional complex games and apps from scratch over the course of days.”
As part of internal testing, the company used Codex to build two web-based games, consuming millions of tokens over extended runs. “GPT‑5.3-Codex sets a new industry high on SWE-Bench Pro and Terminal-Bench, and shows strong performance on OSWorld and GDPval, four benchmarks we use to measure coding, agentic and real-world capabilities,” OpenAI mentioned.
It also better understands your intent when you ask it to build day-to-day websites than GPT-5.2-Codex.
OpenAI has launched a new end-to-end enterprise platform named Frontier. This new tool is claimed to help businesses build, deploy, and manage AI agents as part of their core enterprise infrastructure. Frontier empowers AI agents to work like reliable team members.
“Frontier gives agents the same skills people need to succeed at work: shared context, onboarding, hands-on learning with feedback, and clear permissions and boundaries. That’s how teams move beyond isolated use cases to AI coworkers that work across the business,” OpenAI mentioned in the blog post.
The tech giant revealed that HP, Intuit, Oracle, State Farm, Thermo Fisher, and Uber are among the first to adopt Frontier.
On Thursday (February 5, 2026), Anthropic introduced its latest high-performing artificial intelligence model, Claude Opus 4.6. The company said this model represents a fundamental shift in how AI handles complex workplace tasks. Anthropic appeals to computer coders and enterprises seeking AI products that prioritize data security and predictability.
With the launch of Claude Opus 4.6, Anthropic is clearly signalling its intent to remain a serious contender in the fast-intensifying AI race dominated by OpenAI. According to US media reports, both companies are widely rumored to be preparing for IPOs in the near future.

GPT-5.3-Codex can help with non-traditional developer tasks such as building slide decks and spreadsheets. OpenAI revealed that GPT-5.3-Codex will run processes that last more than a day.
OpenAI has made its intentions clear in an increasingly competitive AI coding landscape. As rivals like Anthropic push rapid advancements with models like Claude Opus 4.6, the focus is shifting from raw model size to real-world developer productivity, reliability, and tool integration.
For AI users, these launches hint at a future where AI agents play a bigger role in everyday work. The AI arms race is accelerating and users can now expect faster iterations, sharper specialization, and a growing emphasis on practical, developer-first innovation.
