OpenAI launches GPT-5.4, its most powerful model for enterprise work—and a direct shot at Anthropic

OpenAI has released GPT-5.4, a new AI model the company says is its most capable system to date for professional use. The model combines advanced reasoning, coding, and the ability to autonomously operate computers and software, turning up the heat in the competition for enterprise customers that has been Anthropic’s stronghold.

The new model consolidates some of the capabilities that OpenAI had previously spread across separate models, bringing together the coding strengths of GPT-5.3-Codex—the company’s leading programming model—improved reasoning skills, and the agentic ability for the model to navigate desktops, browsers, and software applications autonomously.

The model is rolling out on Thursday to ChatGPT Plus, Team, and Pro subscribers, as well as through the company’s API. A more powerful version, GPT-5.4 Pro, is also available for users who need maximum performance on complex tasks.

Alongside the model launch, OpenAI is introducing ChatGPT for Excel and Google Sheets in beta, a version of ChatGPT embedded directly in spreadsheets to build, analyze, and update complex financial models. The company is also launching new ChatGPT app integrations—including FactSet, MSCI, Third Bridge, and Moody’s—designed to let teams pull market, company, and internal data into a single workflow.

It also puts OpenAI in more direct competition with rival Anthropic, which launched similar products as part of the Claude for Financial Services launch in July 2025 that were expanded on later in the year. Both companies are racing to capture the enterprise market with tools that can do real-work for sectors ready to adopt AI.

The new announcement could also spark a fresh wave of investor anxiety about the impact of AI on traditional financial data providers, many of whose stocks have already been affected by broader fears of AI-driven disruption to enterprise software. Earlier this year, the release of Anthropic’s Cowork plug-ins triggered a broad selloff across SaaS stocks, as markets spooked on the idea that AI tools could make legacy software providers obsolete.

New agentic capabilities

One of the most significant aspects of GPT-5.4 for enterprise customers is the out-of-the-box agentic capabilities. The model can operate computers and software autonomously, search for and use external tools on demand, and handle complex, multi-step tasks, all without developers having to build that infrastructure themselves.

OpenAI says GPT-5.4 is the company’s most factual and reliable model to date. The company said in a blogpost they had reduced the rate of hallucinations, with individual claims 33% less likely to be false and full responses 18% less likely to contain errors compared to GPT-5.2.

“Developers don’t just need a model that writes code. They need one that thinks through problems the way they do. We’re seeing GPT-5.4 perform exceptionally well at logical reasoning and executing intricate, multi-step, tool-dependent Workflows,” Mario Rodriguez, Chief Product Officer at GitHub, said of the model.

These new features position OpenAI as a more direct player in the increasingly competitive field of agentic products, such as Perplexity Computer, Microsoft’s Copilot Tasks, and OpenClaw. As demonstrated with the recent popularity of OpenClaw, users are increasingly looking for AI systems that can handle extended workflows with minimal human intervention.

OpenAI also says GPT-5.4 is significantly more token-efficient than its predecessors—meaning it uses fewer tokens to solve problems. Despite being priced slightly higher per token than GPT-5.2, OpenAI says those efficiency gains mean it requires fewer tokens to complete many tasks, which could offset the higher cost for some users.
