On Monday, former OpenAI researcher Andrej Karpathy shared a practical breakdown of ChatGPT’s various model versions, helping users understand which one to use based on their specific needs.
What Happened: In a post on X, formerly Twitter, Karpathy said many users remain confused about ChatGPT versions like GPT-4o, GPT-4 and “o3.”
“o3 is the obvious best thing for important/hard things. It is a reasoning model that is much stronger than 4o and if you are using ChatGPT professionally and not using o3 you’re ngmi,” he said.
He explained that GPT-4o, OpenAI’s latest model, is ideal as a “daily driver” for easy-to-moderate tasks. “o4 is only available as mini for now, and is not as good as o3, and I’m not super sure why it’s out right now.”

Karpathy offered a quick reference:
Use 4o for simple questions (~40% of his use)
Use o3 for complex, high-stakes queries (~40%)
Use GPT-4.1 for casual coding (~10%)
Use the “Deep Research” toggle—powered by o3—for deep dives (~10%)
He added that this guidance only applies within ChatGPT, as he also uses Anthropic’s Claude, Alphabet Inc.’s GOOG GOOGL Google Gemini, xAI’s Grok and Perplexity for other tasks.

Why It’s Important: OpenAI is reportedly expected to generate over $12 billion in total revenue by the end of 2025, up from $3.7 billion in 2024.
While the Sam Altman-led company hasn’t revealed revenue specifically from its enterprise segment, a Reuters report noted that paying seats for its ChatGPT Enterprise offering rose to 3 million in May, up from 2 million in February.
