JoyAI-VL-Interaction is an 8B-scale, vision-first model that autonomously decides to respond or delegate without user prompting, aiming to interact with environmental changes like a human would. The system streams ongoing videos for real-time interaction, with pluggable ASR/TTS modules and a background brain. In evaluations, human raters preferred this model over existing video-call assistants across multiple scenarios. The model and system are open-source, representing a new paradigm in interaction modeling for always-on, perceptive agents.
The paper proposes Data2Story, a multi-agent framework that automates data journalism by mimicking a virtual newsroom with distinct roles. It generates evidence-based news stories in multiple formats, such as text articles, interactive maps, and audio, each linked to data sources for verifiability. In evaluations against expert human journalists, Data2Story showed competitive performance, particularly excelling in transparency and auditability. Human journalists still outperform in editorial angle and creative design. The system is designed as a collaborative tool for journalists, not a replacement.
FastContext is a system that decouples repository exploration from code solving in LLM coding agents to reduce token waste from irrelevant snippets. It deploys specialized exploration models as a dedicated subagent, issuing parallel tool calls and delivering focused context via concise file paths and line ranges. The approach cuts token consumption by up to 60% and improves resolution rates by up to 5.5% relative to baseline agents.
APPO is a new agentic reinforcement learning method that improves multi-turn tool-use in large language model agents. It refines branching and credit assignment by focusing on fine-grained token-level decision points rather than coarse heuristic interaction units. The method selects branching locations using token uncertainty and policy-induced likelihood gains, leading to more precise exploration and better credit distribution across branched rollouts. Experiments across 13 benchmarks show APPO consistently boosts performance over existing agentic RL methods by approximately 4 points. The approach also ensures efficient tool-calls and maintains behavioral interpretability.
HarnessX is a platform that enables composable, adaptive, and evolvable agent runtime harnesses. It introduces compositional primitives and AEGIS, a trace-driven evolution engine that iteratively refines harness design using execution feedback. Traditional static, hand-crafted harnesses are replaced with a substitution algebra for dynamic adaptation. Evaluated across multiple benchmarks, HarnessX achieved an average performance improvement of +14.5% over conventional harnesses, highlighting the impact of runtime interface evolution alongside model scaling. The full codebase will be released in the future.
Researchers propose MRAgent, a framework that improves long-horizon memory reasoning for LLM agents. It uses a Cue-Tag-Content graph representation and an active reconstruction mechanism to dynamically retrieve and prune memory paths during inference. This moves beyond the static retrieve-then-reason paradigm, adapting memory access to intermediate reasoning evidence. Experiments show up to 23% performance improvement over baselines and reduced token and runtime costs. The work demonstrates efficient memory reconstruction for complex agent tasks.
