OpenAI has launched GPT-4.5 for ChatGPT Plus subscribers, offering enhanced reasoning and performance capabilities.

Sesame’s voice AI companion has generated significant attention for its remarkably natural conversational abilities that users describe as crossing the uncanny valley of voice interaction. This breakthrough demonstrates how a relatively small startup has achieved what major tech companies have struggled with, while also highlighting the business challenges of maintaining competitive advantage in the rapidly evolving AI landscape.
