Kuaishou's Kling AI Video Unit Raises $3B at $15B Valuation

Google has released Gemini Omni Flash through an API for enterprise customers and developers, enabling conversational video editing and generation. The model consolidates multiple AI tools into a single interface that accepts text, images, and video as inputs and produces finished clips with synced audio. The API rollout makes the technology accessible to marketing and learning-and-development teams that produce most organizational videos, addressing the cost and timeline barriers that have historically limited internal video production.

Higgsfield AI, a San Francisco-based startup that generates images and videos from text prompts, is raising $300 million to $500 million at a $5 billion pre-money valuation, more than quadrupling its valuation from January. The startup's revenue run rate has grown to $500 million this month, more than double its $200 million run rate five months earlier. The funding round signals investor appetite for AI video generation models tailored to specific use cases.

AWS has published a technical guide for building a voice-based healthcare appointment agent using Amazon Nova 2 Sonic and Amazon Bedrock AgentCore. The agent handles patient authentication, appointment confirmation or rescheduling, and health information collection through natural speech conversation. US healthcare no-show rates range from 5-30 percent by specialty, representing significant lost revenue and provider time.

Loka built a voice AI agent using Amazon Nova 2 Sonic that processes audio end-to-end rather than converting speech to text and back, reducing response latency from 3-5 seconds to near-real-time while lowering costs. The approach achieved a speech reasoning score of 87.0 on Big Bench Audio, outperforming Google's Gemini 2.5 Flash (71.0) and OpenAI's GPT Realtime (83.0). The solution addresses a core frustration with traditional voice assistants: robotic, slow responses that damage customer experience and increase support costs.
