Researchers have developed F-Actor, an instruction-following full-duplex conversational speech model that can be trained efficiently on 2,000 hours of data without large-scale pretraining. The model enables explicit control over speaker voice, conversation topic, backchanneling, interruptions, and dialogue initiation, addressing naturalness limitations in current spoken conversational systems.
StepFun has released Step-3.5-Flash-Base, a text generation model available on Hugging Face under Apache 2.0 license. The model is part of the Step 3.5 series and focuses on efficient inference.
Researchers introduce MemSifter, a framework that offloads memory retrieval to smaller proxy models instead of burdening the primary LLM. The approach uses outcome-driven reinforcement learning to optimize retrieval accuracy while minimizing computational overhead during inference.
Researchers introduced MeanFlowSE, a generative speech enhancement model that eliminates the computational bottleneck of multistep inference by learning average velocity over finite intervals rather than instantaneous velocity fields. The single-step approach achieves comparable quality to multistep baselines on VoiceBank-DEMAND while requiring substantially lower computational cost and no knowledge distillation.
Researchers have released xLLM, an open-source Large Language Model inference framework designed for enterprise-scale serving. The framework claims to achieve up to 2.2x higher throughput than vLLM-Ascend when serving Qwen-series models under identical latency constraints, using a novel decoupled architecture that separates service scheduling from engine optimization.
DeepXiv-SDK introduces a three-layer agentic data interface designed to give LLM agents efficient, cost-aware access to scientific literature. The system transforms unstructured data into normalized JSON, offers retrieval tools via CLI, MCP, and Python SDK, and currently covers the complete arXiv corpus with daily synchronization.
