Hot AI Updates: Zhipu AI Releases 'Glyph' and also Meet ‘kvcached’ (editor's pick)

[Stress Test System from Anthropic and Thinking Machines Lab] A New AI Research from Anthropic and Thinking Machines Lab Stress Tests Model Specs and Reveal Character Differences among Language Models. It introduces a systematic approach that “stress tests” model specifications by generating 300,000 plus value trade off scenarios and measuring cross model disagreement as a quantitative signal of spec gaps and contradictions. The study evaluates 12 frontier models from Anthropic, OpenAI, Google, and xAI, classifies responses on a 0 to 6 value spectrum, and shows that high divergence aligns with specification ambiguities and inconsistent evaluator judgments. Results include provider level value profiles and analysis of refusals and outliers…..

[CV Open Source] Zhipu AI Releases 'Glyph': An AI Framework for Scaling the Context Length through Visual-Text Compression. Glyph scales long context by rendering text into images and letting a vision language model read the pages, which turns token sequences into visual tokens. The research reports 3x to 4x token compression on long text with comparable accuracy to strong 8B baselines. Prefill and decoding speedups are about 4 times, and supervised fine tuning throughput is about 2 times. An LLM driven genetic search tunes font, dpi, and layout for accuracy and compression. Under extreme compression a 128K context VLM can address 1,000,000 token level tasks. Code and model resources are public.

[Open Source AI Infra] Meet ‘kvcached’: A Machine Learning Library to Enable Virtualized, Elastic KV Cache for LLM Serving on Shared GPUs. Large language model serving often wastes GPU memory because engines pre-reserve large static KV cache regions per model, even when requests are bursty or idle. Meet ‘kvcached‘, a library to enable virtualized, elastic KV cache for LLM serving on shared GPUs. kvcached has been developed by a research from Berkeley’s Sky Computing Lab (University of California, Berkeley) in close collaboration with Rice University and UCLA, and with valuable input from collaborators and colleagues at NVIDIA, Intel Corporation, Stanford University. It introduces an OS-style virtual memory abstraction for the KV cache that lets serving engines reserve contiguous virtual space first, then back only the active portions with physical GPU pages on demand. This decoupling raises memory utilization, reduces cold starts, and enables multiple models to time share and space share a device without heavy engine rewrites.
