Microsoft released Magentic-One, a multi-agent system for solving general tasks, which can surf the web, write and execute code, and operate through a computer terminal. It is believed to be intended in part to address rival offerings by Salesforce and the scathing derision Salesforce CEO Marc Benioff has aimed at Microsoft’s agentic products.
Anthropic has unexpectedly raised the price of its Claude 3.5 Haiku LLM, citing its high performance, representing a rare reversal which could potentially signal the end of the era of rapidly decreasing LLM prices.

💡 ANALYSIS

This article explores the ways in which AI agents could revolutionize software DevOps—and where that leaves human engineers.
A recap of an interview with OpenAI executives Olivier Godement and Romain Huet in which Godement lays out the challenges of making AI fully agentic but argues that, in a few years, “every human on Earth, every business, has an agent”.
This piece examines why a recent study found coding agent performance on the dominant SWE-Bench assessment may be overestimated by as much as 20-fold, and argues in detail for more careful evals.
Consumers’ trust in companies is at a record low, but, according to a recent survey by Salesforce, they are open to working with AI sales agents to help address that distrust.
🧪 RESEARCH

Source: ArXiv
This ambitious effort used as many as 1,000 agents interacting with each other in a Minecraft world to simulate human civilization, successfully recapitulating societal patterns such as specialization of labor and the spread of religion. Although such work seems frivolous, it has important implications for training agents to function in real human society.
The authors of this paper solve what they term the Agent Communication Trilemma with a custom protocol for LLM agents to communicate with each other, cutting costs five-fold relative to simple natural language.
Prediction markets require an unbiased “oracle” to adjudicate the outcomes of forecasted events with perfect reliability. This piece gives a case study in how Chaos Labs architected such a system using LangChain and LangGraph.
Thanks for reading! Until next time, keep learning and building!
