- GPT-5.4 is so good for spreadsheets that OpenAI launched an Excel add-on
- Human reviewers also noted a boost in presentation output
- Accuracy is also increased with 18% fewer errors
OpenAI has released its latest GPT-5 model, revealing a new platform with some interesting workplace skills – 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 computation.
And for users who need to give it even more context, Codex is experimenting with supporting up to 1M tokens for longer/more complex workflows and agent 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 released not too long ago.
Because of the spreadsheet performance boost, we’re also treated to an Excel add-in to put ChatGPT right inside the Excel sidebar, just like Google has done with Gemini.
The company also used human reviewers to rate presentation output, claiming they preferred the 5.4’s “stronger aesthetics, greater visual variety, and more efficient use of image generation.”
In addition to performance gains, OpenAI also promises to deliver 33% fewer false claims and 18% fewer responses containing errors compared to 5.2.
GPT-5.4 will be rolled out from 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’s more expensive and slower, but promises more accurate and consistent output with maximum justification.
As for pricing, GPT-5.4 Pro will cost $30/1M input tokens and $180/1M output tokens for the API, versus $2.50/1M input tokens and $15/1M output tokens for the regular GPT-5.4, per OpenAI documentation.
