OpenAI upgrades ChatGPT engine for Excel and Google Sheets

Driving the news: GPT-5.4 is designed to be less error-prone, more efficient and better at workplace tasks like drafting documents, OpenAI said.

• The new model can create files in fewer tries with less back-and-forth than prior models, the company said.
• GPT-5.4 outperformed office workers 83% of the time on GDPval, an OpenAI benchmark measuring performance on real-world tasks across 44 occupations.
• The model can also solve problems using fewer tokens, OpenAI says — which can translate to faster responses and lower costs.
• The company is also debuting OpenAI for Financial Services, a set of new tools that includes the version of ChatGPT that runs inside spreadsheets and new apps and skills within ChatGPT.
• Partners include FactSet, MSCI, Third Bridge and Moody's.
  

Zoom in: OpenAI will offer some of GPT 5.4's advances first to developers and those using OpenAI's Codex developer tool, including native computer use, the ability to search for tools and connectors, and support for up to 1 million tokens of context.
