OpenAI has released GPT-5.4, positioning it as its most capable model for professional work. The update focuses on productivity tasks, delivering a notable jump in spreadsheet accuracy and speed, an Excel sidebar add‑on, and stronger presentation output. Human reviewers reported fewer errors and false claims, while token efficiency improvements enable longer, more complex workflows. The model is available to Pro and Enterprise users through ChatGPT and the API, with distinct pricing tiers for standard and Pro versions.
OpenAI Introduces GPT-5.4 for Professional Productivity
OpenAI launched GPT-5.4, describing it as the company’s most capable and efficient frontier model for professional work. The upgrade emphasizes productivity tools such as spreadsheets, presentations, and documents, delivering measurable improvements across these domains.
In benchmark testing focused on spreadsheet modeling, GPT-5.4 achieved an 87% score, a significant rise from the 68% recorded for its predecessor, GPT-5.2. Human reviewers also noted that the model’s presentation output displayed stronger aesthetics, greater visual variety, and more effective use of image generation.
Excel Add‑On Brings ChatGPT Directly Into Spreadsheets
To capitalize on its spreadsheet strengths, OpenAI released an Excel add‑on that places ChatGPT inside the Excel sidebar, mirroring the functionality Google provides with Gemini. This integration allows users to leverage the model’s reasoning and token‑efficiency capabilities without leaving the spreadsheet environment.
Reduced Errors and False Claims
OpenAI reported that GPT-5.4 delivers 33% fewer false claims and 18% fewer responses containing errors compared with GPT-5.2. These reductions are supported by human reviewer assessments and aim to improve reliability for professional users.
Extended Token Limits for Complex Workflows
The model supports up to 1 million tokens for longer or more complex tasks, enabling richer context and more sophisticated agentic operations. This extended capacity is designed for workflows that require extensive data or multi‑step reasoning.
Availability and Pricing
GPT-5.4 rolled out on March 5 for Pro and Enterprise customers, available through the ChatGPT interface, the API, and a specialized GPT-5.4‑Pro tier. The Pro version is priced at $30 per 1 million input tokens and $180 per 1 million output tokens, while the standard model costs $2.50 per 1 million input tokens and $15 per 1 million output tokens.
Overall, GPT-5.4 represents a focused effort by OpenAI to enhance AI‑assisted productivity, particularly for users who rely heavily on spreadsheet and presentation tools.
