OpenAI released GPT-5.4 on March 5 — the first mainline model with native computer use capabilities, a one-million token context window, and ChatGPT for Excel now in beta for Business and Enterprise users.
Why It Matters
For law firms, consultancies, and finance teams, this changes the operator model. A system that can open applications, navigate spreadsheets, and execute multi-step workflows is closer to an autonomous analyst than a chatbot. The gap between AI assistant and AI employee just got materially smaller.
What To Do About It
If you're on ChatGPT Business or Enterprise, request beta access to ChatGPT for Excel and test it on one real financial model this month. If you're evaluating AI for knowledge work, GPT-5.4 just raised the baseline — your benchmarks from six months ago are outdated.
