This year we’ve seen remarkable advances in agentic AI, including systems that conduct deep research, operate computers, complete substantial software engineering tasks, and tackle a range of other complex, multi-step goals. In each case, the industry relied on careful vertical integration: tools and agents were co-designed, co-trained, and tested together for peak performance. For example, OpenAI’s recent models presume the availability of web search and document retrieval tools (opens in new tab). Likewise, the prompts
