Self-Improving Agents and Optimization Breakthroughs

Ouroboros self-developing agent achieves SOTA on Terminal-Bench and OSWorld. EvoX Genesis builds a C compiler for $44. Replica (27B) beats frontier models on research replication. GLM-5.3 delivers frontier coding and cyber capabilities. AutoDesign introduces meta-harness optimization. Memory retrieval architecture hybrid router pattern improves agent memory systems. New this run: Second Thought parallel reasoning reduces turn count by 43% without accuracy loss — a training-free optimization for ReAct agents, directly addressing idle-window inefficiency.
