The MCP Tax Is Real, and It Is Quietly Killing Your Agent's Reasoning
Every time your AI agent makes a tool call through MCP, it pays a tax. Not in dollars (though that too), but in tokens. Tens of thousands of them. Silently…

RL in the Pre-train Space: Why Training on P(y) Beats Training on P(y|x)
RLVR (Reinforcement Learning with Verifiable Rewards) has been the go-to recipe for boosting LLM reasoning since DeepSeek-R1 made it mainstream. The formula is…

The Three Walls Your AI Research Agent Keeps Hitting
Everyone's building AI research agents. Feed them a Kaggle problem, let them explore, iterate, and submit. The promise: autonomous AI that does your ML…

Chain-of-Thought Was Supposed to Be Our Window Into AI Reasoning. Optimization Is Slamming It Shut.
Here's the deal we thought we had with chain-of-thought prompting: let the model show its work, and we can watch the reasoning unfold. If something goes wrong,…

Tucker Attention: GQA, MLA, and MHA Were the Same Thing All Along
For the last two years, the LLM inference community has been playing a game of architectural bingo. Multi-Head Attention (MHA)? Too expensive at scale.…

Your LLM Doesn't Know When It's Wrong. A Second One Might.
The most dangerous failure mode in production LLMs isn't hallucination. It's confident hallucination. The model is dead wrong, and it's absolutely certain…

The Compression Wars: Why Making AI Smaller Is Now Harder Than Making It Bigger
The AI industry just executed a full 180. For five years, the dominant strategy was simple: make the model bigger, throw more compute at it, watch the…

The Best GPU Kernels Are No Longer Written by Humans
AI agents just outperformed FlashAttention-4 and cuDNN on attention kernels. Not by a rounding error. By 10.5%. Let that sink in. The most aggressively…

Your LLM-Only Agent Loops Are Burning Money. Hybrid Workflows Are the Fix.
Three papers dropped this week that, taken together, tell the same story: the era of "just throw everything at the LLM" agent design is ending. What's…

Gemma 12B Just Destroyed GPT-4o on Web Agents. RL Is the Reason.
A 12-billion parameter open-source model outperforming GPT-4o by 3x on real-world web navigation tasks. That's not a typo. That's what happens when you apply…
