However, the core of these systems has not changed much since early instruction-tuned models like ChatGPT. Even advanced AI agents function on message exchange formats, successively exchanging messages with users, systems, with itself (i.e. chain-of-thought) and tools in a single stream of computation. This bottleneck to a single stream in chat models leads to a number of limitations: the agent cannot act (generate output) while reading, and in reverse, cannot react to new information while writing. Similarly, the agent cannot act while thinking and cannot think while reading or acting on information.\nIn this work, we show that models can be unblocked by switching from instruction-tuning for sequential message formats to instruction-tuning for multiple, parallel streams of computation, splitting each role into a separate stream. Every forward pass of the language model then simultaneously reads from multiple input streams and generates tokens in multiple output streams, all of which causally depend on earlier timesteps. We argue that this data-driven change remedies a number of usability limitations as outlined above, improves model efficiency through parallelization, improves model security through better separation of concerns and can further improve model monitorability.\nReferences & Citations\nLoading...\nBibliographic and Citation Tools\nBibliographic Explorer (What is the Explorer?)\nConnected Papers (What is Connected Papers?)\nLitmaps (What is Litmaps?)\nscite Smart Citations (What are Smart Citations?)\nCode, Data and Media Associated with this Article\nalphaXiv (What is alphaXiv?)\nCatalyzeX Code Finder for Papers (What is CatalyzeX?)\nDagsHub (What is DagsHub?)\nGotit.pub (What is GotitPub?)\nHugging Face (What is Huggingface?)\nScienceCast (What is ScienceCast?)\nDemos\nRecommenders and Search Tools\nInfluence Flower (What are Influence Flowers?)\nCORE Recommender (What is CORE?)\nIArxiv Recommender\n(What is IArxiv?)\narXivLabs: experimental projects with community collaborators\narXivLabs is a framework that allows collaborators to develop and share new arXiv features directly on our website.\nBoth individuals and organizations that work with arXivLabs have embraced and accepted our values of openness, community, excellence, and user data privacy. arXiv is committed to these values and only works with partners that adhere to them.\nHave an idea for a project that will add value for arXiv's community?
