Tandem Training, World Models, and Efficient Agents
Three new arXiv papers on making RL reasoning legible across models, fixing broken world model latent states, and training small agents to beat their teachers.
Refusal Gaps, Prompt Bleed, and Scaling's Logic Limit
Three new papers reveal how LLM safety hinges on persona training, how prompt modules interfere in deployed agents, and why scaling alone cannot reach symbolic reasoning.
Grok 4.3 Review: xAI Bets on Price Over Prestige
Grok 4.3 slashes prices by up to 83%, adds native video input and voice cloning, and carves out a credible position as the most cost-efficient frontier model - with real caveats on coding and latency.
Quantization's Hidden Tax, Cliff Tokens, Smarter Memory
Three new arXiv papers reveal hidden costs in quantized reasoning models, single-token failure triggers, and a new framework that cuts agent memory errors by up to 79%.
AI Diagnosis, Cache Efficiency, and Agent Security
Three papers from today's arXiv: a 32B medical model beats DeepSeek-R1 in rare disease diagnosis, a KV cache method keeps 97% accuracy with 3% memory, and a new benchmark red-teams agentic AI systems.
