Meta's product managers are vibe coding prototype apps and showing them to Mark Zuckerberg (www.businessinsider.com)

Meta product managers are now "vibe coding" prototype apps themselves and showing demos directly to CEO Mark Zuckerberg, using AI assistants to move from idea to working prototype in hours or days. Speakers at the TechEquity AI Summit described Meta’s internal tooling — notably Metamate (a ChatGPT-style assistant trained on internal data) and Devmate (a coding assistant that orchestrates multiple LLMs, including external models such as Anthropic’s) — as powerful enough that non-engineers can tweak interfaces, change designs on the fly, and iterate rapidly. The approach echoes a wider Silicon Valley shift: Google and Microsoft are similarly pushing AI into everyday development and tracking adoption internally through dashboards and programs like Meta’s “Level Up.” For the AI/ML community this signals a structural change in product development: lower barriers to prototyping, accelerated experimentation cycles, and new skill expectations (vibe coding is now a hiring priority at many firms). Technically, it highlights multi-model orchestration, internal fine-tuning on private corpora, and UI-layer integrations that let natural-language instructions generate—or modify—code and front ends. The trade-offs are practical: faster iteration and democratized creation versus new needs for model governance, quality control, and deployment pipelines that can scale safe, maintainable outputs from AI-assisted prototypes.
