Why GPT-5.5 dominates a benchmark that tests how agents improve themselves
EvoPolicyGym isolates a critical but understudied capability: an agent's ability to refine an executable policy through repeated feedback-constrained edits. The benchmark reveals GPT-5.5 as the strongest performer across 16 environments, and provides trajectory-level diagnostics that expose how different agents allocate budget and convert feedback into tuned parameters.

The 12,000-line secret behind Bing's speed: how mimalloc beat the allocator trade-off
Microsoft Research's mimalloc allocator uses thousands of per-page free lists and a clever page-stealing technique to achieve both high concurrency and low memory overhead, as detailed by the RiSE group in a new technical blog.

The benchmark that made language models speak: how 2018's glue bet changed ai forever
The GLUE benchmark, launched in 2018, transformed natural language processing by providing a standardized yardstick for language understanding. Its legacy lives on in every modern LLM benchmark, from SuperGLUE to the latest arena-style evaluations that define today's AI race.

Efficient World Models
Fast-LeWM just made visual planning stop stumbling over its own steps
Researchers introduce Fast-LeWM, a latent world model that speeds visual planning by predicting future states from action prefixes in parallel. The approach cuts computational costs and error buildup, outperforming prior one-step transition models.

Agent Frameworks
IBM's new open-source agent framework cuts the boilerplate and keeps the brains
IBM's open-source CUGA framework flips the typical agent development model on its head by handling orchestration, state management, and planning. Developers are left to write only a tool list and a prompt. Over two dozen single-file apps demonstrate the approach, from a movie recommender to a multi-agent lead-generation system, all deployable in governed production without needing a rewrite.

OPID feeds agents dense rewards from their own past, no external memory needed
OPID extracts hierarchical skill supervision from completed on-policy trajectories, providing dense token-level guidance for language agent training without external memory. Experiments on ALFWorld, WebShop, and Search-based QA show improved performance and sample efficiency over outcome-only RL and existing skill-distillation methods.
