Sora 2 released with improvements on physical world video modeling and a new "character consistency" feature allowing real-world element injection from a single video. The model powers a new Sora social network app with profiles, DMs, and viral videos, emphasizing user control over likeness use. OpenAI employees are actively experimenting with the model. Meanwhile, Anthropic launched Claude 4.5 Sonnet with enhanced intelligence, token efficiency, and agentic tool use, outperforming some competitors and closely tracking GPT-5-high on benchmarks. Ecosystem support includes LangSmith integration and strong coding/math benchmark results.
