Ouroboros is a self-developing agent harness where tools, prompts, and core implementation improve through reviewed commits that become the runtime for subsequent work. It operates via recursive free evolution or experience-driven core evolution triggered by bugs and inefficiencies found during use.
Anthropic has released Claude Opus 5, a model designed to match the performance of Claude Fable 5 at approximately half the price per token while offering more permissive content classifiers. It serves as the new default model on Claude Max and the strongest option for Claude Pro users.
According to the Agent Arena leaderboard, Kimi K3 performs at a level comparable to Opus in non-vision tasks. While some users note that Opus may have an advantage in vision capabilities, the ranking indicates parity for other use cases.
The authors propose ShopX, a foundation model designed to bridge the gap between language understanding and item fulfillment in agentic shopping workflows. Unlike existing approaches that wrap LLMs around separate search pipelines, ShopX uses semantic IDs (SIDs) to allow models to directly operate within the item space.
Researchers introduce PaperPilot, a multi-turn literature search agent that frames scientific search as workflow induction to address underspecified and evolving user intents. Given an anchor paper and query, the system constructs an executable DAG of search operators which can be refined through user feedback.
