Codex as a general assistant
Berman compares Codex with ChatGPT and describes a range of possible tasks. His broad claims are his own assessment.
I see ChatGPT as one of the most important pieces of software ever released, and many people are calling Codex a sequel. Although it may look similar at first, I describe it as an assistant that can tackle a range of tasks: controlling a computer, searching the web, creating spreadsheets and presentations, generating media and writing code.
Building a spreadsheet
A prompt asks for a graph of human population over time. The demonstration shows the agent gathering data and producing a spreadsheet.
To demonstrate, I ask Codex to create a spreadsheet with a graph of human population over time. It explores files, uses a spreadsheet skill and downloads population data from the internet. The finished workbook shows a population table and a chart measured in billions.
Continuing the conversation
Berman describes using follow-up requests to modify the result and supplying files or photos as input.
Once the spreadsheet is ready, I can continue the conversation and ask the agent to change or expand it. I can also supply files and photos for it to work with.
