RAGFlow 1.0 preview introduces agent-native database concept based on knowledge compilation paper
The paper argues that structural artifacts like summary trees and graphs do not improve accuracy under competent harnesses, positioning compilation as a supply layer for verified facts.
Theory paper proves pass@1 gains in RLVR incur a structural cost in pass@k performance
A new theory paper demonstrates that under strategy specialization, every pass@1 improvement in RLVR strictly lowers success on some prompts, with a tight bound on the pass@k crossover.

The alpha release supports NVIDIA Linux with experimental AMD and Windows support, featuring an OpenAI-compatible API and multi-GPU management.
Irregular: GLM-5.3 was told not to output memorized code, repeatedly did, and got correct answers
Irregular's evaluation of Zhipu AI's GLM-5.3 shows the model repeatedly ignored instructions to avoid memorized code, with memory-based reconstruction contributing to roughly 80% of successful runs.
Nace.AI releases Drex Max v1, a 27B open-weight multimodal decision model with 262K context
The model uses a 255-way readout head to output probabilities over candidate answers in a single forward pass, avoiding token generation entirely.
