- GPT-5.4 is so good with spreadsheets that OpenAI released an Excel add-in
- Human reviewers also noticed an increase in the outcome of submissions.
- Accuracy has also increased, with 18% fewer errors
OpenAI has released its latest GPT-5 model, revealing a new platform with some interesting work capabilities, especially if you’re a spreadsheet fan.
GPT-5.4 is being positioned as OpenAI’s “most capable and efficient frontier model for professional work,” offering better token efficiency for reasoning, solving tasks faster, and using less compute.
And for users who need to give it even more context, Codex is experimenting with support for up to 1 million tokens for longer, more complex agency workflows and tasks.
GPT-5.4 loves spreadsheets
For this update, OpenAI focused on professional productivity tasks like spreadsheets, presentations, and documents, and we’re seeing significant improvements across the board. According to the spreadsheet modeling benchmark cited by OpenAI, GPT-5.4 scores 87% compared to 68% for GPT-5.2, a model that came out not long ago.
Given the increase in spreadsheet performance, we’re also getting an Excel add-in to put ChatGPT inside the Excel sidebar, just like Google did with Gemini.
The company also used human reviewers to rate the presentation’s outcome, stating that they preferred the “stronger aesthetics, greater visual variety, and more effective use of image generation” of 5.4.
In addition to increasing performance, OpenAI also promises to deliver 33% fewer false statements and 18% fewer answers containing errors compared to 5.2.
GPT-5.4 will be implemented starting March 5, including Thinking models for ChatGPT, an API, and Codex. Pro and Enterprise users will also get GPT-5.4-Pro on ChatGPT and via the API; It is more expensive and slower, but promises more accurate and consistent results with maximum reasoning.
As for pricing, GPT-5.4 Pro will cost $30/1 million input tokens and $180/1 million output tokens for the API, compared to $2.50/1 million input tokens and $15/1 million output tokens for the regular GPT-5.4, according to OpenAI documentation.
