It would have taken at least 30 minutes to find root cause. Seer Agent had it in seconds (Sponsor)

It looked like Saturday night would be very bad. Sentry's Head of AI, Indragie, was online when Seer, Sentry's AI debugger, had started failing. The issue was an upstream infra outage on the provider's side - but there was no way to figure that out without digging into dashboards. So Indragie pulled up a new tool: Seer Agent. He told it what he was seeing and waited for the answer.It came in seconds. Seer fixed Seer.Read the blog to get the full story.Curious? See how it works in the live webinar on May 19th

Introducing Grok Build (2 minute read)

Grok Build is a coding agent that runs from the terminal. It is now in early beta for SuperGrok Heavy subscribers. AGENTS.md, plugin, hooks, skills, and MCP servers all work out of the box.

2028: Two scenarios for global AI leadership (28 minute read)

Anthropic outlines two possible 2028 global AI leadership scenarios: one where the US retains its compute advantage and shapes AI norms, and another where China competes closely due to policy inaction. The US currently leads due to strong export controls and advanced chip technology preventing China from keeping pace. Closing loopholes on compute access and restricting distillation attacks are crucial for maintaining the US lead and ensuring democracies shape AI governance.

How We Built Secure, Scalable Agent Sandbox Infrastructure (8 minute read)

There are two ways to sandbox an agent that can execute code: isolate the tool or isolate the agent. Agents should have nothing worth stealing and nothing worth reserving. Isolating the agent requires an extra network hop on every operation and more services to deploy, but there are no secrets to steal, no state to preserve, and agents can be killed, restarted, and scaled independently.

Beyond AI Code Review: Why You Need Code Simulation at Scale (Sponsor)

Production failures don't come from bad code. They come from correct code entering a system nobody fully modeled. AI code review tools see the diff. They don't see configurations, dependencies, user behavior, or infrastructure under load. AI code simulations offer a better approach to understanding production impact before code ships.Learn more → | Book a demo →

Genkit Middleware (10 minute read)

Genkit is a framework for building full-stack, AI-powered and agentic applications for any platform. It supports TypeScript, Go, Dart, and Python. Genkit uses composable hooks that intercept generation calls to implement retries and fall-backs for maximum reliability, human approval before destructive tool calls, and observability across every layer. Its middleware system runs a tool loop that repeats until the model is done. The Genkit Developer can be used to inspect, test, and debug applications and middleware execution.

Unlocking asynchronicity in continuous batching (20 minute read)

Asynchronous batching can reduce idle time between CPU and GPU cycles, improving GPU utilization for inference by 22%. By using CUDA streams and events, CPU tasks prepare batch N+1 during batch N's GPU computation, eliminating idle gaps. This method yields more efficient GPU operations without changing kernels or models, enhancing generation speed substantially.

Microsoft is quietly shopping for an OpenAI replacement (4 minute read)

Microsoft signed a deal with OpenAI late April that amended the company's exclusive license to OpenAI models, freed OpenAI to sell on any other cloud, and removed the AGI clause that would have triggered changes to Microsoft's IP rights once OpenAI's board declared the threshold reached. Microsoft's IP license, a 27% stake worth roughly $135 billion, will be kept through 2032. Microsoft is reportedly looking to purchase Inception, a company that builds diffusion-based language models. It is interesting that Microsoft would spend $13 billion on a partner and then immediately start a shadow procurement process for a replacement.

The economics of superstar AI researchers (12 minute read)

Superstar researchers at frontier labs can earn over a hundred times more than the average AI postdoc. Researcher quantity doesn't easily make up for quality in the field of AI. Even a 2x researcher can earn far more than the median because their contributions easily scale to billions of users. If they can add something that multiple 1x researchers can't, then it's worth paying a lot to capture it.

How to achieve truly serverless GPUs (20 minute read)

Inference workloads are more variable and less predictable than training workloads. This makes them a natural fit for serverless computing. However, serverless computing only works if new replicas can be spun up as fast as demand changes. This article looks at how Modal took AI inference server scaling from multiple kiloseconds to just tens of seconds.

Semis Memo: Supply Chain Inheritance (4 minute read)

Compute Optimal Tokenization (2 minute read)

Researchers derived compression-aware neural scaling laws by training nearly 1,300 models, revealing how bytes per token affect compute allocation. This challenges the heuristic that scales models by 20 tokens per parameter, showing it's due to specific tokenizers. The study suggests scaling should use bytes, not tokens, for better compute efficiency across diverse languages.

Reinforcing Recursive Language Models (18 minute read)

The article discusses using reinforcement learning to fine-tune 4B models as recursive language models (RLMs) for production, achieving efficient task-specific behavior at a lower cost. By training a shared policy for both parent and child RLMs, this approach maintains task performance and reduces the need for multiple models. In tests, this method matches the performance of larger models like Claude Sonnet 4.6 but operates with significantly reduced size and cost.
