Hello.
The main topics this week include:
- Anthropic's update to Claude's constitution
- Apple and Google's collaboration on Gemini-powered Siri announcement
- Yann LeCun's launch of a new startup specializing in world models
This week felt strongly themed around "harmony between AI and humans." Anthropic's announcement of Claude's new constitution demonstrates that AI alignment research is transitioning from purely academic discussions to implementation-level work. Meanwhile, the collaboration between Apple and Google—two competing tech giants—signals that the competition over "who can provide the best user experience" in the mobile AI era is heating up.
The emergence of Yann LeCun's new company, AMI Labs, is also intriguing. He has consistently advocated for the importance of "world models" throughout the current LLM boom. AI that understands not just language but also the causal relationships in the physical world—this could be the technology that defines the next decade.
Additionally, OpenAI's engineering blog has published valuable insights for implementers, including the internal loop of the Codex agent and PostgreSQL scaling techniques supporting 800 million users. For those on the "building" side of AI services, such practical information is invaluable.
Notes
- Focuses on recently collected AI and web development news

New AI Models, Services, and Updates
Anthropic: Announces New Constitution for Claude
Anthropic announced an update to the constitution that serves as the core of "Constitutional AI," which guides the safety and ethical alignment of AI models.
This constitution defines the values Claude uses to generate responses and has been updated to be more human-aligned. This represents a significant advancement in AI alignment (harmony with humans) and will directly influence the behavior of future models.

Yann LeCun: Launches New Startup "AMI Labs" Focused on Building World Models
Yann LeCun, Meta's Chief AI Scientist, unveiled the website for AMI Labs, a new company focused on developing "World Models" that understand the physical world.
While current LLMs demonstrate remarkable capabilities in language processing, they have limitations in understanding physical causal relationships. World models are gaining attention as a next-generation AI architecture that can overcome these limitations, and LeCun's new company is expected to increase focus on this field even further.
