ALMA: Meta-Learning Memory for Agents

\n In a groundbreaking shift for agentic systems, researchers from Jeff Clune’s group have unveiled ALMA (Automated meta-Learning of Memory designs for Agentic systems). The system introduces a \"Meta Agent\" that autonomously discovers memory architectures through open-ended exploration in code space. By searching over database schemas, retrieval mechanisms, and update strategies expressed as executable code, ALMA consistently outperforms all human-designed memory baselines across four sequential decision-making benchmarks. This represents a significant step toward AI systems that learn to be continual learners.\n

LLaDA 2.1: Speed Meets Quality

\n Ant Group has released LLaDA 2.1, a major upgrade to discrete diffusion language models. By introducing Token-to-Token (T2T) editing, the model allows for aggressive drafting followed by refinement. The \"Flash\" variant hits an astounding 892 tokens per second, fundamentally changing the speed-quality trade-off in LLM decoding.\n

InftyThink+: Infinite Reasoning

\n Addressing the quadratic cost of long chain-of-thought reasoning, InftyThink+ uses trajectory-level RL to let models autonomously decide when to summarize and resume. The framework yielded a 21% accuracy gain on AIME24, outperforming vanilla long-CoT methods.\n

Agyn: Software Engineering as an Org

\n Agyn models software development as an organizational process with specialized agents (Manager, Researcher, Engineer, Reviewer). It resolves 72.2% of SWE-bench tasks without specific tuning, suggesting organizational design matters as much as model size.\n
