Anthropic analyzed millions of real Claude interactions and found the 99.9th percentile session duration nearly doubled to 45+ minutes in 3 months, with software engineering accounting for nearly half of all agentic use.
Anthropic published a new theory explaining why AI assistants like Claude express emotions and use anthropomorphic language—proposing that models select from personas inherited from fictional characters during training.
Opper tested 53 leading LLMs with a deceptively simple logic question about whether to walk or drive to a car wash 50 meters away. Only 11 models answered correctly — the car must be driven to the car wash.
