Artificial intelligence startup Anthropic says its new AI model can work for nearly seven hours continuously, further signaling AI’s growing presence in the workplace.

During its inaugural developer conference, Anthropic launched two new AI models the startup claims are among the industry's best, at least in terms of how they score on popular benchmarks.

Anthropic is set to roll out two new versions of its Claude artificial intelligence software, including a long-delayed update to its high-end Opus model, as the startup vies to stay ahead of a crowded market.
