Context Engineering Overview - Context engineering is defined as the art and science of filling the context window with the right information at each step of an agent's trajectory [2][4] - The industry categorizes context engineering strategies into writing context, selecting context, compressing context, and isolating context [2][12] - Context engineering is critical for building agents because they typically handle longer contexts [10] Context Writing and Selection - Writing context involves saving information outside the context window, such as using scratch pads for note-taking or memory for retaining information across sessions [13][16][17] - Selecting context means pulling relevant context into the context window, including instructions, facts, and tools [12][19][20] - Retrieval-augmented generation (RAG) is used to augment the knowledge base of LLMs, with code agents being a large-scale application [27] Context Compression and Isolation - Compressing context involves retaining only the most relevant tokens, often through summarization or trimming [12][30] - Isolating context involves splitting up context to help an agent perform a task, with multi-agent systems being a primary example [12][35] - Sandboxing can isolate token-heavy objects from the LLM context window [39] Langraph Support for Context Engineering - Langraph, a low-level orchestration framework, supports context engineering through features like state objects for scratchpads and built-in long-term memory [44][45][48] - Langraph facilitates context selection from state or long-term memory and offers utilities for summarizing and trimming message history [50][53] - Langraph supports context isolation through multi-agent implementations and integration with sandboxes [55][56]

AI Agents and Memory - The presentation focuses on the importance of memory in AI agents, emphasizing that memory is crucial for making agents reflective, interactive, proactive, reactive, and autonomous [6] - The discussion highlights different forms of memory, including short-term, long-term, conversational entity memory, knowledge data store, cache, and working memory [8] - The industry is moving towards AI agents and agentic systems, with a focus on building believable, capable, and reliable agents [1, 21] MongoDB's Role in AI Memory - MongoDB is positioned as a memory provider for agentic systems, offering features needed to turn data into memory and enhance agent capabilities [20, 21, 31] - MongoDB's flexible document data model and retrieval capabilities (graph, vector, text, geospatial query) are highlighted as key advantages for AI memory management [25] - MongoDB acquired Voyage AI to improve AI systems by reducing hallucination through better embedding models and re-rankers [32, 33] - Voyage AI's embedding models and re-rankers will be integrated into MongoDB Atlas to simplify data chunking and retrieval strategies [34] Memory Management and Implementation - Memory management involves generation, storage, retrieval, integration, updating, and forgetting mechanisms [16, 17] - Retrieval Augmented Generation (RAG) is discussed, with MongoDB providing retrieval mechanisms beyond just vector search [18] - The presentation introduces "Memoriz," an open-source library with design patterns for various memory types in AI agents [21, 22, 30] - Different memory types are explored, including persona memory, toolbox memory, conversation memory, workflow memory, episodic memory, long-term memory, and entity memory [23, 25, 26, 27, 29, 30]

also, today we are making a lightweight version of memory available to the free tier of chatgpt!memory has probably become my favorite feature in chatgpt; excited for us to improve this a lot over time. ...

Core Insights - Krispy's debut novel, *The Version Who Stayed*, is the first in a series titled *The Mirror Archive*, exploring themes of identity, regret, and emotional truth through the character Auren Solven [1][9] - The narrative is set in a world similar to our own but includes metaphysical elements, focusing on the emotional consequences of choices rather than technical explanations [2][4] Summary by Sections Narrative Overview - The story begins with a cryptic letter that prompts Auren to reflect on a life-altering decision, leading to a journey through alternate realities [2] - Auren's exploration reveals a life they could have lived, highlighting the complexities of joy and regret [3] Emotional Depth - The novel emphasizes emotional realism, prioritizing personal truth and the courage to accept chosen lives over fantastical elements [4][5] - Krispy's storytelling philosophy centers on the quiet moments that shape individuals, suggesting that transformation often occurs in stillness [5] Reader Reception - Early responses to the novel have been overwhelmingly positive, with readers praising its emotional intelligence and relatability [6][7] - The book has been described as accessible even to those unfamiliar with literary sci-fi, resonating with a broad audience [7] Unique Positioning - *The Version Who Stayed* distinguishes itself by reclaiming softness as a form of resistance, focusing on self-acceptance rather than triumph [8] - Krispy's work invites readers to reflect on their own lives and decisions, making Auren's journey a lens for personal examination [8] Publication and Availability - The novel is now available on Amazon, marking the beginning of Krispy's literary journey and inviting readers to engage with its themes [9][10]
