Scaling MoE reinforcement learning on Amazon EKS with EFA and DeepEP with 40% more throughput
TutoSartup excerpt from this article:
When you post-train a Mixture-of-Experts (MoE) model with Reinforcement Learning from Human Feedback (RLHF) or Group Relative Policy Optimization (GRPO) at scale, three simultaneous challenges emerge... The first requires coordinating heterogeneous compute for rollout generation and policy training... However, sparsity doesn’t remove infrastructure complexity in training... As part of the standa...

Accelerate multimodal RL training with SkyRL on Amazon SageMaker HyperPod
TutoSartup excerpt from this article:
Reinforcement learning (RL) post-training is becoming a standard step in building capable language model agents... Running this at scale, across multiple nodes with hundreds of GPU-hours of rollouts per training run, requires persistent cluster infrastructure... That infrastructure needs to sustain long jobs, recover from hardware failures without losing progress, and provide visibility into train...

NarrateAI: production-ready LLM quality assurance on Amazon Bedrock
TutoSartup excerpt from this article:
Real-Time Streaming Evaluation validates each paragraph the moment it’s produced, overlapping quality checks with generation... The Composite Evaluation Framework runs multiple independent evaluators in parallel against each paragraph... Paragraph independence Validating output paragraph N does not require waiting for paragraph N+1 to be generated... In a sequential pipeline, users wait for all...

Treasury Yield Surge Pressures Rate-Sensitive Shares
TutoSartup excerpt from this article:
Treasury yields continued to rise on Thursday, reaching new multi-decade highs...This relatively weak performance in recent weeks highlights a growing gap versus the broad market, a gap that’s likely to widen if Treasury yields continue to rise... Several factors are driving the bond market’s repricing of yields, including inflation expectations, uncertainty surrounding the Iran conflict, co...

Introducing enhanced custom event buses in Amazon EventBridge for enterprise-scale event-driven applications
TutoSartup excerpt from this article:
Organizations building event-driven applications on Amazon EventBridge typically start with a single custom event bus in one account... To route events between them, teams create multiple event buses connected through cross-account rules or bus-to-bus configurations... Platform teams lose visibility into who is subscribing to which events, cross-account and bus-to-bus routing charges compound quic...
