OpenAI’s Sam Altman and Anthropic’s Dario Amodei had an awkward moment on Thursday as they chose not to hold hands during a group photo of political and tech leaders.

They were on stage at the India AI Impact Summit, alongside Indian Prime Minister Narendra Modi, Google and Alphabet CEO Sundar Pichai, among others. Both had been keynote speakers.

Modi had lifted Altman and Pichai’s hands before an applauding crowd, with others following suit. However, Altman and Amodei, who were next to each other, raised their fists instead of holding hands with one another.

It comes as competition intensifies between ChatGPT maker OpenAI and Claude maker Anthropic, with both vying for their models to become the default choice for consumers globally.

The companies have also recently traded shots over the potential use of adverts in AI models.
