Both need to prove they can turn a profit.
Their main battleground is winning over corporate leaders who want AI tools to boost productivity.
Anthropic is airing Super Bowl ads mocking OpenAI for introducing ads on ChatGPT.
OpenAI CEO Sam Altman called the ads funny but dishonest.
This rivalry began when OpenAI leaders left to form Anthropic in 2021.
Both companies launched product updates this week.
They also face competition from Google, Amazon and Microsoft.
