A preprint introduces a scalable multi-domain dialogue state tracking (DST) framework that uses pretrained BERT to achieve zero-shot generalization across domains without additional training. The system is evaluated on the Schema-Guided Dialogue (SGD) dataset, showing improvement over prior baselines. The work targets scalability challenges in task-oriented dialogue systems like voice assistants.
Anthropic announced that Claude models are the AI backbone of Amazon's newly launched Alexa+, accessed via Amazon Bedrock. The collaboration involved close coordination between Amazon and Anthropic teams over the past year, with Anthropic CPO Mike Krieger leading the integration effort. Alexa+ will begin rolling out in the U.S. within weeks, extending Claude's reach to Amazon's massive consumer device footprint. Anthropic highlights that Alexa+ benefits from Claude's safety capabilities including jailbreaking resistance.
Anthropic has closed a $3.5 billion Series E round at a $61.5 billion post-money valuation, led by Lightspeed Venture Partners with participation from Bessemer, Cisco, Fidelity, General Catalyst, Salesforce Ventures, and others. Proceeds will fund next-generation AI system development, expanded compute capacity, mechanistic interpretability and alignment research, and international expansion. The raise follows the launch of Claude 3.7 Sonnet and Claude Code, with Anthropic citing strong enterprise adoption across customers including Cursor, Zoom, Snowflake, Pfizer, and Amazon's Alexa+.
