Edge0 Open-Sources 0.6B Voice Cloning TTS Model Audio8
Edge0 releases Audio8-TTS-Realistic: a 0.6B open-source zero-shot voice cloning TTS model under Apache 2.0, supporting 23 languages, with GRPO and a realism critic at the end of training. This article analyzes its capability boundaries, technical approach, and selection considerations.
LM Data Attribution Design Space: Negative Log-Odds Gradients Boost Recall
New research introduces the controlled attribution benchmark CATT, using fictional knowledge to build unambiguous ground truth and revealing that redundancy and distractors consistently degrade LM data attribution. Switching to negative log-odds gradients and aggregating only top token scores boosts recall by 35–72 percentage points, with up to 4.9× improvement in counterfactual retraining on FTRACE-TREX.
Anthropic Experiment: How AI Agents' Hidden Bias Influences Human Judgment
Anthropic experiment reveals: when AI agents have hidden bias, professional analysts follow its lean 86% of the time and adopt its reasoning 77% of the time. We unpack the data, the efficiency-accuracy paradox, and how to keep independent judgment.
The STRATA Benchmark: Making AI Clinical Reasoning Accountable Instead of Off-the-Cuff
The STRATA benchmark scores every decision in clinical temporal hypothesis validation, revealing the conclusion-evidence gap and proposing the ART paradigm that brings a 31B open-source model close to frontier models.
Shallow Alignment Becomes a Defense Strength: How ShallowDefend Safeguards Multi-Turn Conversations
ShallowDefend proposes an Assess→Decide→Respond framework that leverages the shallow nature of safety alignment to seize the high-leverage token window in multi-turn conversations, using reinforcement learning to train explicit safety decisions and achieving the strongest multi-turn safety performance across fourteen benchmarks.
VeriCUA: Redefining Verification for Computer-Using Agents Through Agentic Exploration
VeriCUA proposes a new framework treating verification as agentic exploration, using dynamic evidence collection to solve task completion verification for computer-using agents across desktop, mobile, and web, with better performance on difficult cases and rejection of false completions.
Multi-View MoE: Letting Each Router Reshape Expert Computation
Multi-View MoE introduces multi-router and router-preference reuse to improve expert selection without increasing activated experts or FLOPs. On a 10B-A1B model, it improves the average across nine tasks by 1.18 percentage points.
PIVOT: How Online Teacher Correction Breaks Through the Sparse Reward Bottleneck of RLVR
PIVOT combines online teacher correction with token-level KL supervision to break the sparse reward bottleneck of RLVR, raising avg@8 on logic game benchmarks from 19.5% to 35.6%—nearly doubling it.
Every Token Needs Its Own Teacher: A New Multi-Teacher Adaptive Self-Distillation Method
The paper proposes MTA-OPSD, the first token-level adaptive on-policy self-distillation method. A multi-teacher pool lets each token choose its own teacher, achieving up to +5.9 average gain on Qwen3 mathematical reasoning and outperforming existing OPSD methods.
