Improving quality and robustness in LLM-based text-to-speech systems Low-rank adaptation, data augmentation, and chain-of-thought reasoning are among the techniques enabling accent-free polyglot outputs, improved expressiveness, and reliable synthesis.

Low-rank adaptation enables correctly accented polyglot outputs, while classifier-free guidance boosts expressiveness in LLM-based text-to-speech systems.

Intelligence isn’t about parameter count. It’s about time. As AI models grow larger, they become less insightful, not more. To ensure that they continue to learn, we need to reduce their inference time.

As AI models grow larger, they become less insightful. AWS found a formula that could change everything: intelligence is about time, not scale.

How AI is changing the nature of mathematical research What machine learning theorists learned using AI agents to generate proofs — and what comes next.

AI is accelerating mathematical research while overloading peer review systems. Amazon Scholars and @pennengineering.bsky.social professors Michael Kearns and @aaroth.bsky.social on the promise, the problems, and what needs to change.

Formally verified AES-XTS: The first AES algorithm to join s2n-bignum Simplifying and clarifying the assembly code for core operations enabled automated optimization and verification.

AWS mathematically proved its AES-XTS algorithm is correct, creating the largest proof in s2n-bignum. The algorithm protects customer data in EBS, Nitro cards, and DynamoDB.

Optimizing LoRA target module selection for efficient fine tuning Ablation study clarifies trade-offs between accuracy and efficiency when using low-rank adaptation (LoRA) to fine-tune AI models.

A new Amazon study reveals that targeting LoRA at one model sublayer — or "module" — delivers 98% of multimodule-LoRA performance while cutting latency 22.6%.

How AI is changing the nature of mathematical research What machine learning theorists learned using AI agents to generate proofs — and what comes next.

"As scientists studying the theory of machine learning, we’re already seeing a similar transformation in basic scientific methodology, especially for research of a mathematical nature," write Warren Center affiliates Michael Kearns & Aaron Roth in their Amazon Science op-ed.

Designing AI agents that know when to step back As AI agents become more autonomous, the key challenge isn't what they can do; it's how to design the human side of the equation.

Trust, control, and transparency in agentic AI all depend on one thing: coordination. Amazon Scholar James Pierce introduces a framework and a shared vocabulary to design for it.

Dialogue Boost: How Amazon is using AI to enhance TV and movie dialogue New<b> </b>audio-processing technology is making entertainment more accessible for millions of viewers.

🔊 Audio-processing technology from Amazon separates speech from background sounds using sub-band neural networks compressed to &lt;1% original size.

Using LLMs to improve Amazon product listings Large language models are increasing the accuracy, reliability, and consistency of the product catalogue at scale.

Amazon's LLM-based system improves product listing quality by recognizing standard attribute values, collecting synonyms, and detecting errors. The process updates millions of listings within days:

Intelligence isn’t about parameter count. It’s about time. As AI models grow larger, they become less insightful, not more. To ensure that they continue to learn, we need to reduce their inference time.

What makes AI models truly intelligent? AWS VP Stefano Soatto argues it is not the number of parameters, but how quickly they can reason.

Designing AI interfaces that align with how people actually work "If I were to ding the field right now on one thing, it is that there has been a massive lack of creativity on how people interface with these increasingly smart LLMs and agents."

AI models are getting smarter, but we're still interacting with them the same way we did five years ago. Amazon's AGI Lab explains why the interface problem matters as much as the model problem.

Why a 12-year-old forecasting paper has stood the test of time Amazon Scholar Aravind Srinivasan coauthored a 2014 paper about forecasting civil unrest in Latin America, which won a test-of-time award at KDD 2025.

12 years after publication, EMBERS wins the applied-data-science test-of-time award at KDD. The system used open-source indicators like social media posts and satellite imagery to forecast civil unrest across 10 Latin American nations.

The unseen work of building reliable AI agents "Reinforcement learning gyms" train agents on the many low-level tasks that they must chain together to execute customer requests.

Before an AI agent can book your vacation, it must learn to scroll, click, tab, and navigate other low-level tasks. Amazon's AGI Lab is building "reinforcement learning gyms" where agents practice atomic behaviors, mastering mundane interactions that underpin reliable software operation:

Customizing multiturn AI agents with reinforcement learning Leveraging existing environment simulators and reward functions based on verifiable ground truth boosts task success rate, even with small models and small training datasets.

Reinforcement learning boosts AI agent task success two- to fourfold with small training sets. AWS research shows smaller models can match larger proprietary models at 1% to 2% the cost.
