Clinical care changes every day. Can the AI agents supporting it change with it? That question sits at the heart of self-evolving LLM agents in healthcare. These systems aim to do more than run a fixed workflow. They update memory, tools, prompts or coordination strategies based on experience, so future tasks benefit from what came before. Promising as that sounds, the hard part is comparing these systems across papers. One system stores reflections for later use. Another revises its prompts. A third changes how multiple agents work together. Each reflects a different kind of adaptation, yet much of it still gets grouped under the same term. To bring more clarity to that space, our work ๐๐ž๐ฒ๐จ๐ง๐ ๐’๐ญ๐š๐ญ๐ข๐œ ๐€๐ ๐ž๐ง๐ญ๐ฌ: ๐€ ๐’๐ข๐ฑ-๐ƒ๐ข๐ฆ๐ž๐ง๐ฌ๐ข๐จ๐ง๐š๐ฅ ๐“๐š๐ฑ๐จ๐ง๐จ๐ฆ๐ฒ ๐š๐ง๐ ๐’๐ฎ๐ซ๐ฏ๐ž๐ฒ ๐จ๐Ÿ ๐’๐ž๐ฅ๐Ÿ-๐„๐ฏ๐จ๐ฅ๐ฏ๐ข๐ง๐  ๐‹๐‹๐Œ ๐€๐ ๐ž๐ง๐ญ๐ฌ ๐Ÿ๐จ๐ซ ๐‡๐ž๐š๐ฅ๐ญ๐ก๐œ๐š๐ซ๐ž introduces a structured framework that organizes self-evolution across six dimensions: Tools, Memory, Context, Policy, Multi-Agent Coordination and Reasoning. Each dimension includes decision trees with graded levels, from static behavior to deeper persistent change. That makes it easier to see not just whether a system adapts but where and how strongly. We applied this framework to 18 representative healthcare agent papers. Most systems show some form of adaptation but it tends to concentrate in memory rather than deeper changes to tools, policy or reasoning. Memory evolution appeared most often. Prompt self-revision showed up in roughly a third of systems. Tool-selection evolution and learned coordination remained uncommon. Formal policy optimization and reasoning-mechanism evolution did not appear in the reviewed set. The takeaway is not that the field lacks ambition, but that most adaptation today still lives in a narrow slice of what self-evolution could mean. We hope this taxonomy helps researchers and practitioners compare systems more clearly and build adaptive clinical AI with greater rigor.

Recently spoke with @AILovesData on building recommendation systems at scale. My biggest takeaways: ๐Ÿšง Constraints shape solutions more than algorithms ๐ŸŽฏ Defining โ€œgoodโ€ matters more than tuning models โšก The future isnโ€™t LLMs replacing RecSys โ€” itโ€™s LLMs augmenting it Watch here โ†’ youtube.com/live/tCdaYcd0mHQโ€ฆ

Looking forward to the insight discussions!
Be sure to join us tomorrow, January 30th for a presentation from @Ahsaasb, for a deep dive into "Production-Grade ML in Practice: Evaluation and Design Frameworks for Recommendation Systems Serving Millions." Learn more: cohere.com/events/cohere-labโ€ฆ

Production ML is less about fancy architectures and more about judgment, trade-offs, and building systems that survive messy data. Really enjoyed this conversation with Data Tinkerer on what it actually takes to run recommendation systems at scale, and how the role evolves as you grow into senior ML ownership. datatinkerer.io/p/how-to-buiโ€ฆ

Excited to share that Iโ€™ll be giving a talk at Cohere Labs on Production-Grade ML in Practice โ€” focusing on how evaluation and design frameworks actually work at scale for real-world recommendation systems. More details - cohere.com/events/cohere-labโ€ฆ

Our ML Industry group is looking forward to hosting @Ahsaasb, Senior ML Engineer at Instacart for a presentation on "Production-Grade ML in Practice: Evaluation and Design Frameworks for Recommendation Systems Serving Millions." Thanks @PrahithaM and @arya_suneesh to organizing this event! ๐Ÿ”ฅ Learn more: cohere.com/events/cohere-labโ€ฆ

Feature suggestion for @Zoom - If two devices/accounts are detected to be in close proximity and attending the same meeting, mute one of the them by default to avoid Echo.

Happy to share that our paper titled "An Instance Level Approach for Shallow Semantic Parsing in Scientific Procedural Text" has been accepted to the Findings of @emnlp2020. It is very uplifting to see an acceptance at this stage of my academic journey #NLProc @raj_umass_nlp

The #NobelPrize committee couldn't reach Paul Milgrom to share the news that he won, so his fellow winner and neighbor Robert Wilson knocked on his door in the middle of the night.

Today the world changed forever. Why? Because a group of Artificial Intelligence researchers released something called "GPT-3". In short: it's a computer program that can interact like a ridiculously intelligent human. And it will blow your mind ๐Ÿ‘‡
