The prevailing multimodal training paradigm is facing foundational methodological challenges: PRISM research reveals that applying reinforcement learning (RL) directly after supervised fine-tuning (SFT) leads to 'injured training' [4]. Meanwhile, AI Agent infrastructure is rapidly maturing—Vercel has launched Zero, a lightweight programming language purpose-built for Agents [9], and top-tier VCs are collectively betting on the 'boring backend' of vertical Agents [10], signaling a strategic industry shift—from the large-model arms race toward deployable, engineered intelligent agents.

## 🔍 Core Insights
**The multimodal training paradigm** is encountering foundational methodological challenges: PRISM research shows that applying reinforcement learning (RL) directly after supervised fine-tuning (SFT) results in 'injured training' [4]. At the same time, **AI Agent infrastructure** is accelerating its formation—Vercel has introduced **Zero**, a lightweight programming language designed specifically for Agents [9], while leading venture capital firms are collectively investing in the 'boring backend' of vertical Agents [10], marking a pivotal industry shift—from the large-model arms race toward practical, production-ready agent engineering.
## 🚀 Key Updates
- **Cerebras IPO surpasses $100B market cap—the first public-market valuation milestone for the AI inference sector** [3]: Its wafer-scale chip technology has gained strong investor confidence; OpenAI's $10B+ order underscores the strategic value of inference infrastructure.
- **OpenAI launches a preview version of personal finance capabilities in ChatGPT, integrated with Plaid to connect over 12,000 financial institutions** [23]: This marks the first deep integration with real financial accounts—privacy controls and context-aware financial advice are deployed simultaneously.
- **Direct RL after SFT is proven to cause 'injured training'; PRISM proposes inserting a distribution alignment phase** [4]: The multimodal LLM training pipeline is being restructured—RL is fundamentally about 'paying off debt', not performance uplift.
- **Vercel Labs releases Zero—a new programming language purpose-built for AI Agents** [9]: Designed to be smaller, faster, and easier to debug, Zero targets core efficiency bottlenecks in Agent development.
- **GitHub Copilot will launch as a standalone app—early access applications are now open** [11]: Developer tooling is becoming increasingly productized, lowering the barrier to Agent collaboration.
- **Box CEO Aaron Levie: 'Now is the three-year golden window to found an AI company'** [18]: He urges founders to focus on vertical AI, Agent infrastructure, and service-oriented companies—and to avoid the 'model-centricity trap'.
- **Academia open-sources the full Claude Code paper workflow pipeline—6.4k GitHub stars** [5]: Covers research, writing, peer review, and finalization—establishing a standardized, AI-native scholarly workflow.
- **WeChat Reading's data API sparks three novel AI applications: personalized recommendation, blind-spot analysis of perspectives, and cognitive structure extraction** [2]: User behavioral data is emerging as critical fuel for building cognition-layer AI.
