Anthropic's Mike Krieger: Claude 4 'can now work for you for much longer'

Anthropic’s launch of Claude 4 marks a shift toward "agentic" AI, moving beyond simple chat interactions to long-horizon virtual collaboration. Chief Product Officer Mike Krieger, formerly the co-founder of Instagram, explains that the new model excels at autonomous task management and complex coding by maintaining memory over hours of work. To combat hallucinations, the system utilizes a citations API that grounds responses in hundreds of verifiable web or document sources. While competitors like OpenAI focus on multimodality and Google on low-latency models, Anthropic prioritizes cross-tool agency and strategic hardware partnerships, such as integrating with Amazon’s Alexa Plus, rather than building proprietary devices. This rapid pace of innovation has even forced the company to revise its hiring practices, now encouraging engineering candidates to use AI during interviews to demonstrate their ability to orchestrate and refine machine-generated output.
