Reasoning with Sampling: Your Base Model is Smarter Than You Think

"*Frontier reasoning models have exhibited incredible capabilities across a wide array of disciplines, driven by posttraining large language models (LLMs) with reinforcement learning (RL). However, despite the widespread success of this paradigm, much of the literature has been devoted to disentangli..."

I open-sourced Stanford's "Agentic Context Engineering" implementation - agents that learn from execution

"With a little help of Claude Code, I shipped an implementation of Stanford's "Agentic Context Engineering" paper: agents that improve by learning from their own execution. How does it work? A three-agent system (Generator, Reflector, Curator) builds a "playbook" of strategies autonomously: * Execu..."

TokDrift: When LLM Speaks in Subwords but Code Speaks in Grammar

"Large language models (LLMs) for code rely on subword tokenizers, such as byte-pair encoding (BPE), learned from mixed natural language text and programming language code but driven by statistics rather than grammar. As a result, semantically identical code snippets can be tokenized differently depe..."
