Inside Thinking Machines' Interaction Models (17 minute read)
Thinking Machines is an AI research lab focused on human-AI collaboration. It believes that real work benefits from continuous collaboration, where the human clarifies, redirects, and gives feedback as a model goes along. This requires an interface that supports that instead of treating the human as someone who hands off a task and walks away. Thinking Machines' interaction models make interactivity a part of the model itself. The company plans to open a limited research preview in the coming months, with a wider release later this year.

Popping the GPU Bubble (17 minute read)
AI models typically produce one token at a time - you can't compute the third token before you have the second. The GPU does most of the heavy lifting, but there is also some work that needs to be done by the CPU. GPU bubbles occur when the GPU sits idle in a loop waiting for the GPU to complete its job. This article looks at how to hide these bubbles using a technique called pipeline decoding, which involves starting the GPU work on the next token while the CPU is still finishing the last one.

Why Specialization Is Inevitable (4 minute read)
Domain-specialized AI models consistently outperform generalized ones because finite resources require concentrated capacity. This pattern aligns across optimization mathematics, biological evolution, market competition, and machine learning, proving that universal generality is structurally inefficient under resource constraints.

AI and the future of math (2 minute read)
In this podcast interview with Dwarkesh Patel, 3Blue1Brown creator Grant Sanderson discusses how AI's rapid, uneven progress in mathematics provides a roadmap for how it will transform the broader economy. Sanderson notes that while AI can rapidly brute-force fields like geometry, it still struggles with playful combinatorics problems that require deep conceptual creativity.

Evals belong where your code runs (Sponsor)
It's harder than it should be to evaluate agent performance—especially if waiting for a key event that might occur days later.Agent Evals fixes that. Evaluate agents based on real business outcomes just by wrapping existing code, and using data already collected at execution. Try it free.

Meituan launches LongCat-2.0 1.6T parameter model on APIs (2 minute read)
Meituan has officially launched LongCat-2.0, a massive 1.6 trillion-parameter Mixture-of-Experts model tailored specifically for agentic coding, multi-step workflows, and long-context processing. Notably, the model was unmasked as the engine behind "Owl Alpha," a highly popular stealth model on OpenRouter that recently ranked in the top three by global daily volume.

GeneBench-Pro: Scientific Judgment in AI Agents (9 minute read)
OpenAI's GeneBench-Pro is a benchmark that evaluates how AI agents handle ambiguity, revise assumptions, and choose analysis paths in computational biology. It focuses on research-level tasks across genomics, quantitative biology, and translational medicine.

Miles: A PyTorch-Native Stack for Large-Scale LLM RL Post-Training (14 minute read)
Miles is a framework for large-scale LLM RL post-training. It makes frontier-scale LLM RL easier to build, reproduce, and operate. RL post-training has become a distributed systems problem as models have become larger and run across more distributed and specialized hardware. Miles makes large-scale LLM RL training more composable, reproducible, and easier to scale while keeping the core trainer small enough for researchers and infrastructure teams to customize.

Claude Code Is Quietly Fingerprinting China-Linked API Routers (8 minute read)
Claude Code fingerprints custom API routing inside model context. While Anthropic has real reasons to care about unofficial Claude routers, the implementation is not transparent. Its technique makes a line of model context look semantically neutral while using punctuation to carry routing metadata. It almost crosses the line into becoming spyware.
