Core Insights - Context engineering has emerged as a critical concept in agent development, addressing the challenges of managing extensive context generated during tool calls and long horizon reasoning, which can hinder agent performance and increase costs [2][4][7] - The concept was introduced by Andrej Karpathy, emphasizing the importance of providing the right information at the right time to enhance agent efficiency [4][5] - Context engineering encompasses five main strategies: Offload, Reduce, Retrieve, Isolate, and Cache, which aim to optimize the management of context in AI agents [3][14] Group 1: Context Engineering Overview - Context engineering is seen as a subset of AI engineering, focusing on optimizing the context window for LLMs during tool calls [5][7] - The need for context engineering arises from the limitations of prompt engineering, as agents require context from both human instructions and tool outputs [7][14] - A typical task may involve around 50 tool calls, leading to significant token consumption and potential performance degradation if not managed properly [7][8] Group 2: Strategies for Context Management - **Offload**: This strategy involves transferring context information to external storage rather than sending it back to the model, thus optimizing resource utilization [15][18] - **Reduce**: This method focuses on summarizing or pruning context to eliminate irrelevant information while being cautious of potential data loss [24][28] - **Retrieve**: This strategy entails fetching relevant information from external resources to enhance the context provided to the model [38][40] - **Isolate**: This approach involves separating context for different agents to prevent interference and improve efficiency [46][49] - **Cache**: Caching context can significantly reduce costs and improve efficiency by storing previously computed results for reuse [54][56] Group 3: Practical Applications and Insights - The implementation of context engineering strategies has been validated through various case studies, demonstrating their effectiveness in real-world applications [3][14] - Companies like Manus and Cognition have shared insights on the importance of context management, emphasizing the need for careful design in context handling to avoid performance issues [29][37] - The concept of "the Bitter Lesson" highlights the importance of leveraging computational power and data to enhance AI capabilities, suggesting that simpler, more flexible approaches may yield better long-term results [59][71]
一半美国医生都在用的AI产品,OpenEvidence 是医疗界的 Bloomberg
海外独角兽· 2025-09-16 12:04
Core Argument - OpenEvidence fundamentally changes how doctors access and apply medical knowledge by providing a free AI chatbot diagnostic assistant, bypassing traditional procurement processes and achieving viral growth similar to consumer products. This PLG strategy is replacing static databases like UpToDate with interactive, on-demand evidence-based answers in seconds rather than hours. As of now, OpenEvidence has attracted over 40% of U.S. doctors, initially led by residents and now becoming a mainstream tool among attending physicians, physician assistants, and over 10,000 hospitals [5][10][12]. Market Landscape - OpenEvidence's Total Addressable Market (TAM) intersects two markets: the annual $20 billion marketing budget for healthcare professionals (HCP) in the U.S. and the global $16.6 billion Clinical Decision Support (CDS) market [22]. - The U.S. marketing budget for doctors in 2024 is approximately $28 billion, with about $9-10 billion allocated to digital channels, while $19 billion (around 68%) is still spent on field sales representatives. Digital and point-of-care channels are expected to grow at a CAGR of 9-11% over the next five years [23][24]. - The global CDS market is projected to reach $16.6 billion by 2030, with a CAGR of 7.6%, driven by increasing physician burnout, the surge in EHR data, and the declining costs of LLM inference [26]. Competitive Landscape - OpenEvidence competes with traditional clinical content platforms like UpToDate, which has a strong trust and procurement relationship but is expensive (around $300 per seat) and slow to innovate. OpenEvidence offers a free model that could disrupt this market [50][52]. - AI-native challengers like Abridge and Suki focus on capturing clinical workflows, which poses a risk of OpenEvidence being marginalized as a reference tool rather than a core workflow component [53]. - Big Tech companies like Google and Microsoft have significant advantages in model capabilities and distribution channels, which could allow them to rapidly expand if they integrate clinical-grade assistants with EHR systems [56]. Business Model and Revenue Forecast - OpenEvidence's business model is evolving from a free-to-use model to enterprise-level monetization, primarily through targeted advertising from pharmaceutical companies and medical device manufacturers. The core search experience remains free to maximize user engagement and data network effects [45]. - Revenue is expected to be predominantly from advertising (over 95% in 2025), with a gradual introduction of subscription models starting in 2026, priced 20-30% lower than UpToDate [47][48]. - By 2028, the projected annual recurring revenue (ARR) could reach approximately $230 million, with a shift towards more stable subscription and API revenue streams [49]. Product and Technology - OpenEvidence focuses on providing efficient and accurate clinical support through a unique interactive interface that includes cross-references and literature lists, ensuring traceability and verifiability of information [35]. - The product features a dual-response mode: Care Guidelines and Clinical Evidence, allowing for in-depth interaction and support for complex clinical decisions [36]. - OpenEvidence has achieved a score exceeding 90% on the U.S. Medical Licensing Examination (USMLE), outperforming general LLMs and significantly reducing common AI "hallucination" issues, thereby enhancing trust in AI assistants [38][40]. Team and Funding - The company is led by CEO Daniel Nadler, a successful entrepreneur with a strong academic background, supported by a team of top talents from Harvard and MIT, focusing on translating research into practical applications [57][58]. - OpenEvidence raised $210 million in Series B funding in July 2025, with a post-money valuation of $3.5 billion, indicating strong investor confidence in its growth potential [61].
