AI startup Runway has launched Gen-4, a high-fidelity video-generating AI model designed for individual and enterprise customers. The tool promises consistent characters and environments, allowing users to create dynamic videos without fine-tuning. Supported by investors like Salesforce and Google, Runway is venturing into the competitive landscape of AI video generation. As it faces legal challenges regarding copyright issues, the company aims to secure a new funding round valued at $4 billion. A recent study indicates that generative AI could disrupt over 100,000 entertainment jobs by 2026.
