A Dual Approach to AI Power

OpenAI introduced GPT-5.4 in two distinct variants: GPT-5.4 Thinking and GPT-5.4 Pro, as reported in Business Standard. This strategic split caters to different user needs and complexities.

GPT-5.4 Thinking: Guided Intelligence

GPT-5.4 Thinking is now accessible to Plus, Team, and Pro subscribers of ChatGPT, taking over from its predecessor, GPT-5.2 Thinking. This version introduces a groundbreaking feature: it displays a preliminary plan of its thought process within ChatGPT. This transparency allows users to intervene and guide its direction even before the final answer is generated, fostering a more collaborative AI experience. It also better retains context over long tasks.

GPT-5.4 Pro: Enterprise-Grade Performance

For those needing maximum performance for the most intricate tasks, GPT-5.4 Pro caters to ChatGPT Pro and Enterprise plan users, according to Business Standard. This variant is designed for the most demanding enterprise applications, leveraging more computational power for complex problems. Free ChatGPT users will also benefit, as their requests will be automatically routed to GPT-5.4 when appropriate, ensuring everyone experiences the latest advancements.

Unprecedented Capabilities: Native Computer Control and Expanded Context

GPT-5.4 introduces several technical advancements that push the boundaries of AI interaction and data processing.

Native Computer Control

A cornerstone technical advancement in GPT-5.4 is its native computer control. This innovative feature allows AI agents to operate desktop environments, simulating mouse movements and interacting with software interfaces through screenshots. GPT-5.4 can manage applications and execute multi-step workflows, a capability available through its API and the Codex agent system. This makes GPT-5.4 the first primary OpenAI model with such native computer control abilities, opening doors for unprecedented automation.

Expanded Context Window and Enhanced Image Processing

Furthermore, GPT-5.4 drastically expands its context window to an impressive 1 million tokens. This immense capacity permits the analysis of vast datasets or extensive codebases in a single processing run, significantly reducing the need for manual data chunking and improving comprehension. Image processing also sees significant enhancements, now supporting high-resolution images up to 10.24 megapixels in their original format, allowing for more detailed visual analysis.

Accuracy and Efficiency: Reduced Hallucinations and Token Optimization

OpenAI has reported marked improvements in accuracy and factual reliability with GPT-5.4, addressing one of the long-standing challenges in large language models: hallucinations.

Minimizing Hallucinations

The model exhibits significantly fewer hallucinations; the error rate for claims has decreased by approximately one-third (about 33%) compared to GPT-5.2, according to OpenAI’s introduction. Overall, GPT-5.4 shows an 18% reduction in errors when juxtaposed with GPT-5.2. GPT-5.4 Thinking, in particular, is hailed as OpenAI’s most factually accurate model to date. These improvements are crucial for applications requiring high reliability, and the model also enhances web searches for highly specific queries.

Token Efficiency and Cost Considerations

Despite increased API prices—$2.50 per million input tokens and $15 per million output tokens—GPT-5.4 is more token-efficient than its predecessors. This improved efficiency aims to offset the higher costs by reducing the actual consumption of resources for equivalent tasks. The knowledge base for these new models now extends to August 2025, ensuring more current responses and reducing the need for external web searches, further contributing to efficiency.

Enterprise Integration and Financial Sector Focus

GPT-5.4 solidifies OpenAI’s push into enterprise solutions, demonstrating a clear focus on integrating AI into professional workflows and specialized sectors like finance.

Seamless Spreadsheet Integration

OpenAI has unveiled a new suite of ChatGPT integrations that embed GPT-5.4 directly into Microsoft Excel and Google Sheets, as announced on the OpenAI website. These integrations facilitate granular analysis and automated task execution within spreadsheets, transforming how businesses handle data. Imagine automating complex financial models or generating reports directly from your sheets with AI assistance.

New App Integrations and Financial Products

New ChatGPT app integrations aim to consolidate market, corporate, and internal data into a single workflow, featuring partnerships with entities like FactSet, MSCI, Third Bridge, and Moody’s. This creates a unified platform for comprehensive data analysis. In addition, OpenAI has announced a suite of secure AI products for businesses and financial institutions built upon GPT-5.4. These products are specifically designed for advanced financial analysis and Excel-based modeling, offering a robust toolset for the financial sector.

The Wider GPT-5 Family

The GPT-5.4 launch is part of a broader family of models, including the recently released GPT-5.3 Instant, ensuring a comprehensive upgrade across OpenAI’s offerings.

GPT-5.3 Instant: Enhancing Everyday Conversations

The launch of GPT-5.4 closely followed the release of GPT-5.3 Instant, just two days prior. GPT-5.3 Instant aims to refine everyday chat conversations by delivering more fluent, direct, and relevant responses, while also reducing overly cautious language. It is available to all ChatGPT users and developers via the API as gpt-5.3-chat-latest, improving the general user experience. A routing layer in ChatGPT automatically selects the most appropriate model (Instant, Thinking, or Pro) for each user request.

For those who prefer older models, GPT-5.2 Instant remains an option for paying users in the legacy models section until June 3, 2026. Similarly, GPT-5.2 Thinking will also remain available as a legacy option for three months, before being decommissioned on June 5, 2026.
